How Is the CNC Spring Forming Machine Beneficial for Manufacturers?

The importance of the coiled metal spring has only been growing since its invention in the 18th century. Heavy duty coiled metal springs are popularly used in items ranging from shocks in bicycles to even instruments for the aerospace industry. Much of the world’s springs are made by the use of manually operated machines based on the engineering designs of the late 19th century. However, backed by several advantages, companies are increasingly shifting their preference towards the CNC spring forming machine.

 

What Is The CNC Spring Forming Machine?

CNC or Computerized Numeric Control is a technology where digital commands are interpreted by a physical machine so as to perform specific precision manufacturing function. Like the modern CNC based wire bending machine and the pipe bending machine, the spring forming machine has a set of mechanical arms with strong iron based components that can precisely bend metal wires to make springs, based on the set of CAD/CAM commands that are provided to a connected computer.

 

Cost Efficiency Guaranteed

Compared to traditional spring forming machines, the modern CNC spring forming machine can directly save the cost of labor and transportation. In traditional manufacturing settings, companies are often required to outsource the spring production to another producer. But with the entry of affordable CNC based spring bending machines in the market, many modern equipment manufacturers already produce spring within their own facilities. This has allowed manufacturers to not just make their supply chain leaner but also reduce the overall production cycles. With this innovation, individuals and businesses can even set up their own new spring manufacturing plant at drastically lower prices compared to the traditional settings, without even requiring the installation of expensive furnaces.

 

Option to Mass Customize

One of the biggest advantages of the CNC spring forming machine is the added ability to manufacture different varieties of springs with the same machine. In traditional settings, tedious changes have to be made so as to manufacture different variety of springs. But, with the CNC, a mere change in the CAD/CAM command can easily allow the manufacturing of different diameter and size variants of springs as required along the next stages of production. In fact, the CNC spring forming machines can even exceed the capacity of production, compared to traditional settings.

 

Saving Manufacturing and Warehousing Spaces

The modern CNC spring forming machine can be adjusted even in tight spaces to manufacture springs as and when required. The highly rapid and efficient production of springs means that companies don’t need to spend their resources on maintaining enormous warehousing spaces for the springs, in the manner they would need to do for traditional industries. Hence, with the host of advantages offered by CNC, an investment in the CNC spring forming machines is indeed justified.

Guide of Laser Cutting Machine: The Right Way to Find Laser Cutting Equipment

This type of capital equipment expenditure is a big deal, so fabricators should know what to ask to find the right fit.

 

Tailift Laser Cutter 

For most manufacturers, buying an industrial laser cutting machine is a major investment. It’s not just the initial price you pay, but the fact that the purchase will have a great impact on the entire manufacturing process. If the wrong equipment is chosen, you have to live with the decision for quite a long time. It is not unusual to see manufacturers keep a laser for seven to 10 years.

 

Do you know the best way to go about purchasing a laser cutting machine? Even if you currently own one, how long ago did you buy it, and what has changed since then?

 

This guide should help you in making a capital purchase decision that will drive your manufacturing operations to new heights.

 

What’s The Application?

Perhaps the real question is, “Should I even be buying a laser cutting machine?” For many reasons, investing in a different cutting system may make more sense for a company’s manufacturing activities. Investigating all available options can minimize any possible regrets in the future.

 

Depending on the part volume, a stamping press may deliver the lowest cost per part. When speaking of metal forming in a press, however, you also are talking about the need to invest in tooling. Stamping also presents the ability to perform multiple tasks, such as forming and tapping, as part of the production process.

 

A traditional turret punch press can cut out holes and shapes economically, but, again, it involves tooling. A punching machine also can’t match the production speeds of laser cutting machines. As with a stamping press, some forming can be done on the punch press.

 

A high-definition plasma system is good for thick materials and for applications in which the edge quality isn’t critical. An abrasive waterjet also is good for thick materials and for applications in which the metal can’t have a heat-affected zone, which is a problem with most thermal cutting methods. Both plasma and waterjet cutting systems cost less than laser cutting machines, but many times do not match the laser’s cutting speed. Of course, plasma cutting and waterjet systems can boost productivity with the use of multiple heads and the ability to cut stacked blanks; the application obviously would influence what exactly you need.

 

Do We Really Need to Invest in Laser Cutting?

A company that doesn’t have a laser cutting machine generally subcontracts the work to one or several job shops with that capability. This scenario doesn’t involve a lot of risk and can work if you have some flexibility with lead times.

 

But there will come that time when you have to ask yourself if it is time for the company to bring laser cutting in-house. This has to be considered even if the business relationship with the subcontractor is great.

 

How do you know if it is the right time to own a laser? Look at how much you are spending monthly for laser-cut parts. In the words of Henry Ford, “If you need a machine and don’t buy it, then you will ultimately find that you have paid for it and don’t have it.”

 

If the decision is made to bring laser cutting in-house, you may be put in a position where you need to justify why the investment needs to be made. The costs associated with subcontracting out the laser cutting are just the starting point for the justification. How much more productive will the manufacturing process be with in-house laser cutting? How does this affect lead times? From an expense standpoint, not only do you have the cost of the laser cutting machine, you have labor and consumable costs, such as laser cutting assist gas.

 

Figuring out these answers will give upper management or even a lending institution an idea about production savings and subsequent return on investment following the initial investment.

 

What Does It Mean to Control the Laser Cutting Process?

Other than monetary issues, when manufacturers offer reasons as to why they are looking at purchasing a laser cutting machine, they mention “control.” Ask yourself these questions to see if you fall into this category:

 

  • How many times have we lost business because of late delivery?
  • Have we ever had to reject parts because of poor quality?
  • How would it help our image if we had our own laser cutting capabilities?

 

Who Should We Buy the Laser Cutting Machine From?

As a manufacturer, you have numerous sources to purchase a laser cutting machine. There are dealers that specialize in used equipment and original equipment manufacturers that offer state-of-the-art cutting equipment and even refurbished machines that may not have the production process of new machines, but still can perform much more efficiently than machines of a similar age with no rework done to them.

 

Ask the OEMs questions about service availability. Today’s technology does not require as much maintenance, but when a machine goes down, you’ll want it back up and running as soon as possible. Also find out about parts availability and delivery. Again, a laser cutting machine that can’t cut because of a damaged part just doesn’t cut it.

 

Be aware that laser cutting machines from OEMs that are recognizable in the industry typically have higher resale values.

 

CO2 or Fiber Technology?

Two types of lasers currently make up a majority of the industrial market: traditional CO2 gas lasers and newer solid-state fiber lasers. CO2 lasers have been the workhorses of the metal fabricating industry for the previous two decades. These lasers operate by running electricity through a gas-filled resonator (which includes CO2) and using mirrors to focus and deliver the beam. In a fiber laser, banks of diodes are used to create the laser, and it is channeled and amplified through fiber-optic cable, similar to that used in the telecommunication industry.

 

The fiber laser, which made its debut around 2008, has lower operating costs and delivers higher cutting speeds than the CO2 laser. Early on the fiber technology could cut at these higher speeds only on thin materials, but with the advent of more powerful lasers, fiber lasers are demonstrating robust cutting speeds even in 0.5-in.-thick material. As a result, fiber laser cutters tend to be a popular choice, despite their higher price.

 

Also, fiber technology may open new opportunities for a fabricator. These machines can cut reflective material, such as brass and copper, whereas it is difficult for CO2 lasers.

 

Some applications still remain better suited to CO2 lasers, such as applications that require good edge quality on thicker or specialized materials. Also, some manufacturers may feel comfortable with CO2 technology because they’ve used it for several years, and the company has in-house maintenance expertise.

 

After the end of the warranty period, keep in mind that you will have to make a decision about ongoing maintenance. Are you comfortable relying primarily on the OEM for service, or do you like to be self-sufficient, perhaps relying on a third-party source for any maintenance? Because the fiber laser has fewer moving parts or mirrors when it comes to laser generating, unlike a conventional CO2 resonator, it will require less maintenance over its lifetime.

 

Will We Need Material Handling?

Choosing some level of automatic material handling equipment also is an important consideration. This is even more important today, primarily because of the significantly faster cutting speeds of the fiber laser technology.

 

That’s why it’s necessary to understand just how you will use this new laser cutting capability. Do you plan to run the laser only a few hours each day or multiple shifts? Based on the typical time to process a sheet of material, can your operator keep up with manually loading and unloading the laser, even if it has a second shuttle table? How important is minimizing the labor cost in the part production to making a profit and remaining competitive in your business?

 

Sometimes metal fabricators choose not to buy material handling automation immediately. If you choose this route, ensure that pallet systems or even an automated storage and retrieval tower can be added easily in the future.

 

Will We Need New Software?

In many instances, manufacturers are already using a software package that everyone is used to. Will that software be able to work efficiently with the new laser cutting machine, or will you be better off purchasing the OEM’s software? If the latter, what new capabilities come with the new software?

 

As more of the manufacturing world is talking about increased interconnectivity among machines and software systems, it behooves you to ask if the new software is capable of running other machines already in place on the shop floor. Additionally, it’s worth having a conversation as to how the laser might integrate into the company’s network. Laser cutting speeds aren’t the only thing increasing at an incredibly fast pace; collecting pertinent manufacturing information in the blink of an eye is leading to more timely and impactful decision making for manufacturers.

 

What Is the True Cost of Running the Equipment?

With such a large investment, a manufacturer needs to know at what level of efficiency the equipment is operating. You need to know more than just if the machine is running or not running. This is where equipment performance monitoring comes in.

 

It’s important for you to find out if software can measure the laser cutting machine’s overall equipment efficiency (OEE) in real time. If so, can the software be used for your other laser cutting machines, if you have them, so that you might discover “hidden capacity” where you thought there was none?

 

With the cost of about 1 percent of the equipment price, monitoring software can provide a 10 to 50 percent productivity gain with paybacks of less than four months.

 

How Will We Finance the Purchase?

While some manufacturers pay cash for a laser, the majority use some method to finance the purchase. Don’t assume that your bank is the best source for funding the laser equipment purchase. Look at other alternatives, including the OEM, many of which own their own financing arms.

 

Also, don’t assume you will receive better service if you choose the OEM’s financing option.

 

What’s Involved with Delivery and Installation?

Preparation is required for a successful delivery and installation. First, what type of foundation, if any, is going to be required? Second, the laser cutting machine has to be located in the right place in the facility, preferably away from harsh environmental areas. You also should have found the best location for the laser so that it contributes to an efficient flow of laser-cut blanks to downstream manufacturing processes.

 

For a lot of companies, the delivery of a new piece of major manufacturing equipment is a new experience. The company that supplied the laser cutting machine can answer your questions about shipping and rigging; they do this all the time.

 

What Can Be Done to Make the Purchasing Decision Easier?

Answering these questions and obtaining quotes based on the feedback can be used to narrow down the selection of the supplier of a laser cutting machine to two to three sources. From there you need to find the right model, ask the right questions during equipment demonstrations, and work toward an acceptable price. Remember, there are many important items to discuss during the final negotiation.

 

The purchase of such a machine can be an overwhelming task. That’s why it might make sense to join an industry association, such as the Fabricators & Manufacturers Association, to network with manufacturing peers to learn from them, or even seek out the assistance of someone that has been through or is familiar with this type of industrial equipment purchase. Such an effort likely would prove to be worthwhile.

 

If you have interest or requirement of laser cutting machines, I recommend you to visit Tailift Co., Ltd. – they are the world-famous fiber laser cutting machine manufacturer. You can find high quality, efficiency, and accuracy laser cutters at Tailift. Now, contact with Tailift for more details of laser cutting.

The Different Types of Plastics and How they are Recycled

It’s in bottles, containers, wrapping, and other everyday items. Plastic is as versatile as it is recyclable. By recycling the plastics you use every day, you can reduce your impact on the environment and help businesses cut costs. However, not all types of plastics are created equal. The number within the recycling symbol on plastic containers provides a wealth of information about their safety, biodegradability and recyclability. Here’s a 101 of what these various SPI codes mean.

 

  1. PETE or PET (Polyethylene Terephthalate)

Commonly found in beverage bottles, perishable food containers and mouthwash, clear PET plastics are generally considered safe, but can absorb odors and flavors from foods and liquids stored in them. Most recycling programs accept this plastic. PET plastics are recycled into carpet, furniture, and fiber for winter garments.

 

  1. HDPE (High Density Polyethylene)

HDPE is another commonly recycled plastic deemed safe. HDPE products have a very low risk of leaching into foods or liquids. You’ll find this plastic in milk jugs, yogurt tubs cleaning product containers, body wash bottles and similar products. Many children’s toys are also made from HDPE. Recycled HDPE is made into pens, plastic lumber, plastic fencing, picnic tables and bottles.

 

  1. V or PVC (Polyvinyl Chloride)

Found in food wrap, plumbing pipes, tiles, windows and medical equipment, PVC is seldom recycled. PVC plastics contain harmful chemicals linked to a variety of ailments, including bone and liver diseases and developmental issues in children and infants. Keep PVC items away from foods and drinks. Specialized programs recycle PVC into flooring, paneling and roadside gutters to name a few.

 

  1. LDPE (Low-Density Polyethylene)

More recycling programs are beginning to accept LDPE plastics. A very clean and safe plastic, LDPE is found in household items like plastic wrap, grocery bags, frozen food containers and squeezable bottles. Recycled LDPE is made into such items as garbage cans, paneling, furniture, flooring and bubble wrap.

 

  1. PP (Polypropylene)

Another safe plastic, PP is quite sturdy and found in Tupperware, syrup bottles, medicine bottles and yogurt containers. PP is recycled into heavy-duty items like pallets, ice scrapers, rakes and battery cables. Many recycling programs accept PP.

 

  1. PS (Polystyrene)

An easily recognizable plastic, PS or Styrofoam is found in beverage cups, insulation, packing materials, egg cartons and disposable dinnerware. Styrofoam is notorious for leaching and poor recyclability, though some programs may accept it. PS is recycled into various items including insulation, school supplies and license plate framing.

 

  1. Miscellaneous Plastics

SPI code 7 is a potpourri of plastics, one of which is polycarbonate. Sunglasses, computer casing, nylon, compact discs and baby bottles may contain #7. These types of plastics are hard to recycle and contain the toxic chemical BPA, a dangerous hormone disruptor that can cause health problems. Plastic #7 is primarily recycled into plastic lumber and specialized products.

Swing Arm Clicker Press Maintenance

The most widely used die cutting machine in the world: the swing arm clicker press. If you’re reading this post, perhaps you own or manage one. With a good operator that has a routine or system, a swing arm clicker press can put out a lot of cut material in a small amount of time. It’s important to take care of your dies and make the right adjustments for that respective die, but it’s also important to keep your machine maintained for optimal performance, and protection of those dies.

 

Swing arm clicker presses are most frequently used with leather, footwear, gaskets, foam & rubber, plastics and textiles. Let’s say you just received a large sheet of rubber and have a die (or dies) that need to be cut with it. You go to turn on your machine and get it warmed up, adjust the height settings, do a test press, and notice that the machine is pressing down too hard. When this occurs, your order may need to be halted. This not only bottlenecks your process, but it sets back the recipient of the order, and if it happens mid-pressing, it could ruin your die.

 

Regular maintenance can avoid downtime, ruined dies, and even increase productivity. You can best maintain your machine by keeping it and its components clean. Debris and dust can clog filters and cause electrical components to lose connection.

 

Sometimes the issues can be something simple, or it could be something more serious like a cylinder seal replacement. All of them revolve around press pressure. Some issues we see include:

 

  • Electrical Component Failure, in particular, the pressure switch. When this component starts to fail, the press may start acting up and give you differential pressure between cuts.
  • Motor or pumps can go bad, which causes a loss of pressure. Perhaps you used to be able to cut on 5, now you need to set the press to 9 or 10.
  • Broken Hydraulic System. You may see air in the oil, holes or lose hoses, and filter issues.
  • Bad seals

 

If you have issue or requirement of swing arm clicker press, I recommend you to visit MINZ Inc. – they are the professional manufacturer of specializing in eco shoe cutting machines. Now, welcome to check out their website for more details of ECO hydraulic swing arm cutting machine.

What are Thermoforming and Vacuum Forming?

Thermoforming

The Thermoforming process converts plastic sheet into products using heat. It is a process where heated thermoplastic sheets are molded to conform the sheet to a mold and once the shape is formed and allowed to cool, it is trimmed to create a part or product.

 

Heavy-gauge thermoforming typically produces more “permanent” or end use types of products. Thick or heavy gauge thermoforming usually requires tooling specific to each part because the part size can be very large and parts are trimmed on CNC routers or die cutting presses.

 

Vacuum Forming

Vacuum forming consists of heating a thermoplastic sheet to make it pliable and then applying vacuum pressure between the mold surface and the plastic sheet to remove any trapped air so the sheet conforms to a male or female mold, depending on the characteristics of the part. The additional pressure can allow thicker gauge material to be formed with more intricate detail and sharper corners.

 

What Is The Difference Between Thermoforming And Vacuum Forming?

The difference between thermoforming and vacuum forming is that vacuum forming has the additional process where vacuum pressure is used to conform plastic to the mold during forming.

 

If you have requirements of vacuum forming services, please do not miss Marathon Enterprise Co., Ltd. – they are the professional and experienced thermoforming plastic sheet supplier in Taiwan. At Marathon, you can get services of customizing PP sheets, LDPE sheets, transparent plastic sheet, PP food container, etc. To get more details, please do not hesitate to contact Marathon at +886-3-3590801.

Common Types of Deburring Machines

The deburring industry offers a number of solutions for deburring and parts finishing – almost any type of need can be addressed by a deburring machine solution. The markets and applications for these deburring machines are also wide in variety – including automotive, aerospace, defense, and, of course, manufacturing.

 

Most deburring solutions begin with a customer consultation that takes into consideration a number of highly-specialized requirements that must be met for a competent and complete solution to be suggested or custom-built. No application need is exactly like another. Given that there are a number of differences between the more common deburring machine solutions, the following is a listing of a number of deburring solutions and a description of their use.

 

Portable deburring machines come in a number of varieties. Some come on casters and some come on carts. Portable deburring machines are an excellent choice for shops that employ CNC mills or lathes. The portable deburring machine on casters can be maneuvered to accommodate finishing needs after the primary cutting is completed – right as the parts come off the mill or lathe.

 

The magnetic deburring machines offer an in-line, through-feed deburring process that is typically suited for higher production requirements. Traditionally, these magnetic deburring machines address flat parts that require deburring on both sides. A magnetic conveyor belt helps to keep parts in alignment as they are passed by both sets of brushes. As these deburring machines are capable of handling parts in quantity, an integrated coolant system keeps the system cool and helps to prolong brush life. The magnetic deburring machines can typically handle parts up to 4” thick and at 6” in diameter.

 

The bevel gear deburring machine makes use of a single large-diameter nylon radial brush to deburr small bevel gears. Dual spindle models allow for the loading or unloading of a part while another part is under the deburring process. Again, an integrated coolant system comes standard.

 

A parallel-axis gear deburring machine is rugged, dependable, and efficient – a perfect deburring solution for a manufacturer with a number of different parts profiles that need to be stored and recalled when there is a call for a particular deburring need. The parallel-axis gear deburring machine is a deburring workhorse that can store hundreds of part profiles for recall. The parallel- axis gear deburring machine also features a zero set-up changeover system that eliminates most of the time required to switch from one type of part to another.

 

A ring gear deburring machine offers consistent quality in deburring a variety of parts sizes. Like many of the other large deburring machines, these ring gear deburring machines feature an integrated coolant system as well.

Guillotine vs. Swing Beam Shear

Guillotine Shear:

A guillotine shear is a machine that can shear or cut various materials with a guillotine design. The word “guillotine” is associated with a blade that drops along a vertical track. This type of machine was primarily used in familiar history as a method of execution, particularly in the French Revolution, but the modern guillotine shear cutter is a tool used to form and shape products for a market.

 

The principles of the guillotine shear were incorporated into the design of metal shears and have been the primary design for all of these years. Some of the shortcomings of a guillotine shear are that it must run in gibs and ways and therefore need a certain amount of clearance which has a direct effect on the thinnest sheet that can be cut.

 

Also, the ram moves down with approximately 1 degree of backward motion. This allows the cut sheet to clear the back gauge and drop, although sometimes even this is not enough and the cut part is wedged between the lower blade and the back gauge.

 

When a guillotine shear has a throat it must be heavily re-enforced to avoid the deflection that would normally result from a deep throat. The apron of the upper ram is heavily gusseted to keep the blades parallel to the bottom blades. This system has worked well for hundreds of years however times change and new engineering becomes available.

 

A guillotine type shear can have several different applications in the manufacturing industry. They can be used for either wholesale or retail product design i.e. a sheet metal wholesaler can use a large guillotine shear model to cut simple pieces of raw material for tier pallet shipping; a retail shop can use a different model of guillotine shear to shape metal pieces for specific designs for any kind of retail item.

 

Swing Beam Shear:

On a swing beam shear the ram moves on bearings so there is no play what so ever. This allows the swing beam shear to be able to cut paper as long as the blades are sharp. The ram moves from a fulcrum point in the rear of the side frames giving the shear a massive amount of plate between it and the cutting point. This means almost no detectable deflection.

 

The back gauge is attached to the bottom of the cutting column and moves up as the blade goes down. This means there will never be a possibility for the material to become stuck between the blade and the back gauge.

 

Rather than gussets on the apron a swing beam shear wraps the entire ram as one solid gusset making it much stronger than a similarly gusseted ram. It can have a deep throat with no possibility of deflection and can cut even the thickest piece of metal with a very low rake angle.

 

In my opinion the swing beam shear reviewed the short comings of the guillotine shear and fixed them; however, it is important to remember that before making a decision on purchasing any kind of a shearing machine factors such as the type of shear, required capacity, productivity options, and safety should be carefully evaluated.

 

One important consideration used in deciding what shear is the right one for any job is the capacity required to perform the job. Most of the shears on the market today list capacities for mild steel and stainless steel. It is advised to compare a fabricator’s requirements to those of the actual machine.

 

Some shear capacities are rated on mild steel, which may have 60,000 pounds per square inch (PSI) tensile strength, while others are rated for A-36 steel or 80,000 PSI tensile strength.

 

Capacities for stainless steel are almost always less than those for mild or A-36 steel. Surprisingly enough certain grades of aluminum require as much power to shear steel does. As always, when making a decision on any kind of metalworking machinery purchase, it is important to work with a reputable and knowledgeable company that can answer all the questions regarding the performance and capacity for the machine.

 

If you need more information of swing beam shear or hydraulic guillotine shear, I recommend you to visit Yeh Chiun Industrial Co., Ltd. – they are the professional manufacturer of specializing in press brakes and hydraulic shears. Now, check out their website and feel free to contact with Yeh Chiun for more details.

Everything You Need to Know About Diamond Files & How to Use Them

What is a Diamond File?

Diamond Files are manufactured by electroplating diamond on to steel blanks using nickel. The smaller the particles, the finer the grit of the file. This is why diamond files are referred to in grits rather like sandpaper. The higher the number, the smaller the grit and the finer the finish. For example a 600 grit diamond file will be much finer than 220 grit.

 

Why Use a Diamond File instead of a Traditional Steel File?

As you know traditional steel files have teeth rather like a saw blade. The smaller the teeth, the finer the cut of the file, but all these teeth are lined up in the same direction. So this means that with a traditional file it will only cut in one direction like a saw. Even when you have a round or half round file, they still only cut in a forward direction. They don’t work sideways or in a circular motion, for example.

 

In contrast diamond files don’t actually have teeth as such, but diamond grit. This gives diamond files the unique property in that they will work in any direction.

 

Diamond Files cut in all directions, produce a better finish

The distribution of diamond particles enables the diamond needle file to not only cut in all directions but also produce a much better finish. Therefore diamond needle files can offer a fantastic abrasive for a variety of applications.

 

Due to the hardness of diamond, diamond files can be used on a variety of materials that other abrasives will not have an impact upon.

 

Diamond Files Cut On The Pull Stroke As Well As The Push Stroke

When you’re working in small intricate areas the diamond file will work on the pull stroke just as effectively as it does on the push stroke. So this may make it slightly easier in confined spaces. It also means in theory that it will cut twice as fast as a toothed file of the same grit because it’s cutting on the pull as well as on the push stroke.

 

Another huge advantage is the fact that they also work sideways and with a twisting motion.

 

How to Use Diamond Files

  1. Use The Tip Of A Diamond File For Detailed Areas Such As Ring Shanks

You can use the fine tiny points of the files to get into tiny areas. As long as you can move the file in any direction, it will cut and it will file for you. This is particularly useful with a large round 600 grit diamond file tool as it can be rotated inside a hole or outside a ring, and it will cut in 360 degrees.

 

Great for the inside of ring shanks and also for deep burring. A large half round 220 grit file is also great for the inside of rings and bangles and it has a nice wide flat profile so that can be used on the outside of rings without changing files. A great companion to the 600 round file.

 

  1. Sharpening Carbide Cutting Tools

Over time tungsten carbide cutting tools will dull and it is often easier to have a hand tool abrasive that you can take straight to the cutting tool, rather than having to take a cutting tool to an electric grinding wheel. 600 grit diamond files are the best grade for this application.

 

  1. Enlarging Holes

A round diamond needle file can be used for opening up a huge array of holes in hardened surfaces, 600 grit being the most common for most applications. Small screw holes in watches and clocks to holes in jewels and beads can all be opened up with a round diamond file tool. Choose diamond files that are either 600 or 900 grit for the best results.

 

  1. Removing Excess Solder

If you solder a post onto the back of an earring, for example, a square 600 grit diamond file will help you get right into that solid joint and clean up both the horizontal and vertical surfaces. It also has a very nice sharp point. A round diamond file can be used for removing excessive solder inside a ring band and the finish is finer than what you would achieve with a traditional ring file.

 

  1. Fitting Clock And Watch Glasses

Sometimes when fitting watch or clock crystals the sizes need to be altered slightly, the use of a 600 grit diamond needle file will produce the required result in minimal time.

 

  1. Refacing Clock & Watch Pallets

Clock and watch pallets are very hard and become burred and mis-shapen over time. The use of a 900 grit fine diamond file can radically change the surface of the pallet for a more efficient movement.

 

  1. Shaping Precious Stones For Jewellery

Precious stones can be extremely hard, especially quartz, sapphire and ruby, and when setting stones into jewellery small alterations may be required. No other abrasive will have such an effective impact as a diamond needle file. Fine grades such as the 600 and 900 grit are ideal for making these small adjustments. Try a small flat 600 grit file, or a small half round 900 grit for superfine finishes.

 

  1. Repivoting Clock And Watches

Removing the burrs and wear from pivots is often difficult due to its hardness, especially in French clocks. The use of a 600 grit diamond needle file can have the pivot running smoothly in no time at all.

 

  1. Bevelling Cut Crystal Glasses And Filing Glass

We all know it is very easy to chip the rim of your precious crystal glass and due to the cost of replacing one in a set, using a diamond needle file can be far more economical to bevel the lip of the glass. It is essential that a 600 grit diamond file is used and half round shape is by far the most versatile for the contour of the glass.

 

  1. Sharpening Household Objects

Scissors, penknives, garden tools, kitchen knives, small screwdrivers, guitar and violin strings can all be sharpened to a razor sharp finish in very little time. You can use various sizes of diamond file for this application but a 600 grit is recommended.

 

  1. Cross Graining Burnishing Tools

Over time burnishing tools lose their burnishing ability, only diamond files can re-address the cross grain of a sapphire burnisher or hardened steel burnisher. Opt for the 600 grit for the best results.

 

  1. Sharpening Fishing Hooks And Ice Screws For Winter Climbing

One of the most important tools of an angler has to be his hook and in carp fishing in particular this has to be razor sharp (sticky sharp) The use of a Flat 600 grit diamond needle file is ideal for this due to its size and profile. It is very important that the very hard to find diamond escapement file is used for this operation, this allows dexterous filing all around the hook point.

Workholding of the Month: Turret or Gang Tooling?

What Is Gang Tooling and Turret Tooling?

While you can mount a conventional manual lathe Quick Change Toolpost (QCTP) on a CNC lathe, this is typically only done for toolroom lathes. For production lathes, tooling is generally mounted either on a gang plate or on a turret. Ironically, the picture shows both formats in use, each turret tool station has a gang plate mount, which multiplies the number of tools available from each turret position.

 

Pure gang tooling is the simplest option. In this mode, the tools are mounted in a row on the lathes cross slide. Accessing a tool is a matter of pulling back from the work piece along the spindle’s axis to keep the tools from colliding, sliding the X-axis until the correct tool is in position, and then moving along the Z-axis back to start cutting.

 

Which One Is Better?

There’s a long list of pros and cons for each that we’ll get to shortly, but as promised, let’s start with the top level conclusion:

 

The choice of gang tooling versus turret on a CNC lathe has more to do with what kind of parts you’ll be making than anything else. Gang tooling is very hard to beat for smaller diameter, short parts that don’t require a tailstock. Turrets are hard to beat for versatility, and are a must-have when you need a tailstock for your part.

 

In going through the many articles I researched on the topic, I frequently came across machinists who wished they could use their gang lathes for everything, but had turret machines for parts that were too long and thin to be made with a gang lathe. In some ways, that almost means that the “competition” between gang and turret is a bit misleading. Perhaps a better “competition” would be gang lathes versus Swiss machines.

 

In exchange for more cost, complexity, and the requirement of bar stock that is more expensive because it has to be compatible with the Swiss bushing setup, a Swiss machine can turn parts that would be too long and spindly to do with a gang lathe.

 

Gang Tooling Advantages

  • Speed

Let’s start with the Gang Tool Gang’s view on why their machines are better.

 

If the part can be made on a gang lathe, it can be made faster and more cheaply than on a turret.

 

Remember, some parts just can’t be made on a gang lathe because you can’t use a tailstock – the gang tooling would run into the workpiece if it can’t get completely away from the workpiece, which it can’t because the tailstock is in the way. There are some gang lathes that have retractable tailstocks, but retracting a tailstock each time a tool change is needed defeats the main advantage of a gang lathe – super fast tool changes.

 

The gang tool change is super-fast because it uses slide motion to do tool changes and requires no turret indexing. If you think about it, the typical turret has to move to its tool change position before it can start to spin the right tool into place. Once the tool is in place, it can then move back to cutting position. This is almost exactly the same amount of motion needed for the worst-case gang tool change, but the gang tool has no indexing to do – It moves to the tool change position (different for each gang tool) and moves the next tool into place, then moves straight back. The most commonly used tools are placed in the center of the gang plate and they only move a small fraction of the distance to the furthest tool change position the turret needs.

 

Hence the gang tool is nearly always faster. You hear quotes from gang tool machinists like, “The gang tool machine can finish the part, part it off, bar feeder advance the material, and its well into the second part before the turret lathe can finish the second op.”

 

  • Simplicity and Low Cost

Turrets are expensive precision devices with lots of moving parts. Gang tooling is minimalist. It involves a few blocks mounted on the cross-slide and that’s it. The lathe’s normal axis motors and leadscrews do all the work for a tool change. This means gang lathes can often be a lot cheaper than turret lathes. In some cases, shops buy two gang lathes for what a single fancy dual-spindle turret lathe would’ve cost and feel they’re coming out way ahead.

 

If your part needs live tooling, perhaps to machine wrench flats onto a part or to drill a bolt circle on a flange, it is much cheaper to do with gang tooling. Pneumatic spindles, cable driven spindles, and smaller electrical spindles can all be pressed into service if the lathe has an index able C-Axis spindle. Motorizing a turret drives up the cost in many ways because of the difficulties of transmitting rotary power out to the tool positions on a rotary turret. It also drives up the size of the turret, making live turret tooling impractical on smaller lathes.

 

Gang tooling tends to be cheaper while turret tooling tends to be more costly, but can be larger scale and more robust.

 

  • Fast Setup

This is one that swings back and forth, but if you look at the ability to swap out an entire block of tools easily with gang tooling, it’s hard to see how setup can’t be done more quickly since it can be done offline or saved as an assembled block of tools for various jobs.

 

Alternately, a lot of gang work can be done with a basic set of tools and just changing one block that holds a twist drill of a particular size, for example.

 

  • Accuracy

Simplicity and a reduction in moving parts eliminates tolerance stack up and various kinds of slop (backlash) in the moving parts of a turret. The accuracy issue is all about achieving the correct center line (Y-axis) position with the tool. Once shimmed into place, or a custom bushing drilled for a twist drill, it’s hard to get more accurate.

 

Another factor that gives the gang lathe an accuracy advantage is they’re used to move shorter distances while machining a part.

 

  • Robustness

This one is closely related to simplicity. There’s not a lot to go wrong on a gang lathe. A turret has all the wear points and parts to break of a gang lathe plus a whole lot more. If you crash a turret, you may have an expensive repair bill, or you may simply need to realign it.

 

Turret Advantages

  • Flexibility

Let’s turn to turrets before we start thinking gang lathes are the only way to go. The number one advantage of a turret is flexibility. You can use a tailstock with one, which allows much longer and skinnier parts than could be made on a gang lathe.

 

In addition to length, turrets allow larger diameter parts. If you think about it, a gang tool setup needs clearance for the part to fit between any two tools. This limits the diameter or the number of tools you can put on the gang plate. The turret lets you have your cake and eat it too because it leaves room for much larger diameter parts.

 

  • Much Easier Programming

While experienced gang lathe users find programming easy, beginners will find turret programming to be far easier than gang tooling. With the gang lathe you have to worry about clearing the part for a tool change. This can be tricky with different setups and part diameters. Make a wrong move and a tool crashes into the part.

 

Also, gang users have to deal with the idea of both positive and negative, since tools are on either side of the workpiece. Turret users only have to deal with one sign and generally pick positive since that’s simpler and more intuitive. Of course, the fancier lathes will mount both a front and a rear turret, at which point they deal with positive and negative as well.

How Do Hydraulic Jacks Work?

A jack is a device that uses force to lift heavy loads. The primary mechanism with which force is applied varies, depending on the specific type of jack, but is typically a screw thread or a hydraulic cylinder. Jacks can be categorized based on the type of force they employ: mechanical or hydraulic. Mechanical jacks, such as car jacks and house jacks, lift heavy equipment and are rated based on lifting capacity (for example, the number of tons they can lift). Hydraulic jacks tend to be stronger and can lift heavier loads higher, and include bottle jacks and floor jacks.

 

How Do Hydraulic Jacks Work?

 

Hydraulic jacks depend on force generated by pressure. Essentially, if two cylinders (a large and a small one) are connected and force is applied to one cylinder, equal pressure is generated in both cylinders. However, because one cylinder has a larger area, the force the larger cylinder produces will be higher, although the pressure in the two cylinders will remain the same. Hydraulic jacks depend on this basic principle to lift heavy loads: they use pump plungers to move oil through two cylinders. The plunger is first drawn back, which opens the suction valve ball within and draws oil into the pump chamber. As the plunger is pushed forward, the oil moves through an external discharge check valve into the cylinder chamber, and the suction valve closes, which results in pressure building within the cylinder.

 

Types of Hydraulic Valves

 

Two common types of hydraulic jacks include bottle jacks and floor jacks.

 

  • Bottle Jacks

Bottle jacks became popular in the early 1900s when the automobile industry began to take off. Also called hand jacks, bottle jacks provided an easy way for an individual to lift up a vehicle for roadside inspection or service. Their resemblance to milk bottles earned bottle jacks their name—today, they range in size and weight to offer a lifting capability ranging from one hundred to several tons. Bottle jacks feature a vertical shaft, which supports a platform (called a bearing pad) that directly bears the weight of the object as it is lifted.

 

Although they are most commonly used in the automobile industry (1.5 to 5 ton jacks are frequently used to lift cars), bottle jacks have other uses as well. In the medical industry they can be used in hydraulic stretchers and patient lifts. In industrial applications, they can be found as pipe benders used in plumbing, as cable slicers for electrical projects, and as material lifts within warehouses. Their ability to lift heavy loads plays a big role in enabling the repair of large agricultural machinery and in many construction operations. Bottle jacks can be secured within a frame, mounted on a beam, or simply used as they are for easier jack transportation.

 

  • Floor Jacks

Unlike bottle jack shafts, the shaft in a floor jacks is horizontal—the shaft pushes on a crank that connects to a lifting pad, which is then lifted horizontally. Floor jacks typically provide a greater range of vertical lift than bottle jacks, and are available in two sizes. The original jack is about four feet long, a foot wide, and weights around 200 pounds—they can lift 4-10 tons. A more compact model was later made, which is about three feet in length, and can lift 11/2 tons.  Although “mini jacks” are also produced, they are not a recognized standard type of floor jack. Typically, one of the first two sizes should be used.
