Does Automotive Wheel Machining Benefit From a Purpose-Built Wheel Machine?


Victor Taichung Machinery Works, based in Taiwan, makes a wide variety of machine tools, including turning machines and multi-purpose milling machines, but an interesting specialty application of the company are wheel machines.

 

In the video above, we speak with Wayne Hsueh, director of overseas marketing division at Victor Taichung Machinery Works about the difference between wheel machines and general purpose multi-axis machine tools.

 

“The car wheel machine is for clamping the part, because for the part to be clamped, you need a special chuck,” Hsueh explained.

 

“Usually for special purpose machines, the chuck is the key component to reduce setup time and for clamping efficiency. Wheel chips are also different from steel chips, so even a chip conveyor and the protection of ball screws are also somewhat different. For special purpose machines, you should pay attention to the kind of part you’re making, what kinds of chips are produced, what kind of coolant you use and how you dispose of it.”

 

Hsueh explains that Victor Taichung’s special-purpose wheel machines are actually modified general-purpose machines – this saves costs for the company as well as its customers.

 

“We can mass produce all the machine parts, as 80 percent of parts are compatible (between machines),” Hsueh said. “We have some customers that want special-purpose machines only and we pay a lot of attention to them. If we increase production of our general-purpose machine, the special-purpose machine would also become cheaper. We like it cheaper for mass production. That’s why we have a special machine for wheels, but wheel machines are heavy duty for heavy cutting. You need a very reliable machine base and fortunately at Victor Taichung Machines, we build the machines this way from the beginning.”

Understanding The Different Types of CNC Lathe Machine

Many people are surprised that there are different kinds of CNC lathes. Although the concept behind the machines is much the same, there are differences. Before choosing just any CNC lathe services, it would be helpful for you to have a better understanding of this machine and its unique types. That way, you end up hiring the right CNC cutting service – one that can accomplish what you need done.

 

Lathe Machine Types

 

For CNC lathe machines, there are four primary types.

 

  • Speed Lathes –

    The speed lathe has a simple design. On this machine, there is only a headstock, tailstock, and tool post. Although the speed lathe only operates in either three or four speeds, the spindle speed is high. Typically, people use this type of lathe for light machine work, including metal spinning, wood turning, and metal polishing.

 

  • Engine Lathes –

    Of all lathe machines, the engine lathe is the most commonly used. Not only is this lathe incredible for lower-power operations, but it is great for high-power operations as well. This machine also comes in a variety of lengths up to 60 feet. Although many CNC machine shop services rely on even more sophisticated equipment, an engine lathe is often part of the lineup. This lathe also operates on a broad range of speed ratios, and because of that, it can machine different metals.

 

  • Turret Lathes –

    Especially for quick operations, the turret lathe is ideal. Mounted on to a single structure are various types of tool posts. This single setup makes it possible to finish jobs quickly. Along with a capstan wheel for positioning the next tool, this machine performs a sequential process using the turret but without the workpiece moving, thereby preventing errors associated with misalignment.

 

  • Tool Room Lathes –

    By being so versatile, this type of lathe machine provides unbeatable and enhanced finishing. Also, the tool room lathe has more speeds, it gives different feeds, and for manufacturing die, it works perfectly.

 

Along with the most common types of lathe machines, there are others, including automatic lathes, brake drum lathes, crankshaft lathes, duplicating lathes, jeweler’s bench lathes, and multi-spindle lathes.

 

Trusting the Best

 

With so many options, it is important that you choose the right CNC lathe services.

Something You Should Know About Capping Machines

An Excellent Automatic Capping Machine is must-have equipment in liquid packing line.

 

Capping machines are used to secure caps onto bottles and drums. There are three basic types of equipment: manual, semi-automatic, and automatic. Manual capping machines aid in the setting or holding of products. Operators are responsible for most controls and activities. Semi-automatic capping machines allow a single operator to perform routine activities quickly and accurately. These cappers help with both placement and packaging. Automatic capping machines perform activities without operator intervention. In fully-automatic applications, operator involvement is limited to the replenishment of packaging components.

 

Types of Capping Machine

Rate and cap type are important specifications to consider when selecting capping machines. The rate is the number of pieces per minute that the capper produces. Cap types include:

 

  • Child-Resistant Closures:

Child-resistant closures (or caps) have a mechanism that makes it difficult for a child to open. Pharmaceutical container caps are an example.

 

  • Cork Caps:

Cork caps use the lightweight elastic outer bar of the cork oak, especially for bottle closures.

 

  • Crimp Flutes:

Capping machines press crimp flutes into the flaring skirt of a shallow metal disk. In turn, this disk holds an inner disk made of a resilient lining material to form the actual seal.

 

  • Press-On Closures:

Press-on closures are held in place through the use of beads or undercuts instead of threads. They are sometimes called snap-fit closures.

 

  • Screw Caps:

Screw caps are secured to the container with a threaded connection.

 

  • Tamper-Proof Seals:

Tamper-proof closures change in appearance after they are removed. An example is a tear-off band from a cap that either falls off or tears so that the break is easily seen.

 

  • Tear-Off Caps:

Tear-off caps or seals are designed to be torn off. Capping machines designed for specialized or proprietary closing methods are also available.

 

What are The Applications of Capping Machinery?

Capping machines differ in terms of applications and features. Some cappers are designed for industrial or general packaging operations. Others are designed for agricultural, chemical, cosmetic, or food and beverage processing applications. Capping machines for household products, medical and military-related products, paints and coatings, and pharmaceutical products are also available.

 

The Recommendable Automatic Capping Machine Manufacturer

Having reliable automatic capping machine is essential in liquid packing line, different types of capping machine will be involved in the capping process depended on the closure type and package shape. KWT carries versatility capping solution for different scope of packaging line.

 

Established in 1997, KWT is the leading packaging machinery manufacturer in Taiwan.

Understanding Modern Press Brakes

This overview provides a brief discussion of press drives, crowning systems, and tooling setup found on today’s press brakes.

 

Does this sound familiar? An operator is working with a mechanical press brake, which has a ram that has to complete its full cycle and a stroke cycle speed that can’t be adjusted, but before he can get started he has to figure out the appropriate bend allowance and k factor for the job.

 

If that sounds familiar, you have been around press brakes for quite a while, or you have a good knowledge of how bending used to occur in fabrication shops. You also probably know that bending is not done that way for the most part today.

 

Modern press brakes are much safer and don’t require as much manual intervention as their predecessors. They are sophisticated machines designed to keep pace with today’s rapid fabricating environment. Let’s take a look at the different elements that separate today’s modern equipment from yesterday’s older pieces of iron.

 

The Press Drive

Hydraulic press brakes are not necessarily new, and that explains why they perform most of the forming work in fab shops.

 

Their operation is very simple to understand. These presses operate synchronized hydraulic cylinders on the C-frames that move the ram. A flow control feeds oil into cylinders to move pistons, which control the movement of the ram. It’s an inexpensive way to generate a lot of force.

 

In the old days, a limit switch was used for controlling the brake. Now CNCs are used. Along with high-precision flow control valves, today’s hydraulic press brakes provide a great deal of control and power cost-effectively.

 

Most of these hydraulic valves are mounted directly on the hydraulic cylinders. A number of years ago, fabricators had to deal with pipes breaking and rams falling. The press brake manufacturers solved the problem by eliminating or minimizing the piping. Today’s hydraulic press brakes should not be confused with those from several years ago.

 

Hybrid brakes are now more widely available than ever before. With a hydraulic drive, when you turn the pump in one direction, you are pumping the ram down. When you turn the pump in the other direction, you are pumping the ram up. The hybrid concept kind of simulates a screw and a nut. It’s a bidirectional pump, and a servomotor controls the pump’s back and forth motion. You don’t have a three-phase AC motor droning all day long, pumping the ram occasionally. Now the motor is pumping the ramp only when the CNC calls for the force.

 

What are the advantages? You get fast response time, minimal piping, good speeds (2 to 500 inches per minute [IPM]), and high efficiency when it comes to performance. However, a hybrid brake is not an inexpensive system.

 

Electric press brakes have made a big splash in the market in recent years. Many fabricators associate “electric” with direct-drive press brakes. In these electric devices, a ball screw system, which relies on recirculating balls to alleviate friction instead of lubricants, drives the rams down.

 

Roller screw technology has emerged as a new technology that helps to increase the load capacity for these electric brakes. These screw types have multiple threaded helical rollers that are found around a threaded shaft. This setup converts a motor’s rotary motion into linear movement to move a press brake ram. These roller screws tend to add more load-bearing surface in the press drive.

 

What are some of the advantages? It’s not necessarily the speeds, but the acceleration factor. Typically press brakes can accelerate only at a certain rate. With an electric brake, you can take that acceleration factor much higher without drawing air bubbles into the oil and so forth.

 

Some manufacturers are using dual drives on the electric brake; one drive is for rapid approach and the other drive is for the bending. This allows you to tune your ball screws and roller screws for different applications.

 

It should be mentioned that there’s another way to convert a small force to a large force. Let’s call it the block-and-tackle drive. Brakes with belts are an example. It also can be called a single-acting electric drive.

 

With this type of drive, the ram moves in one direction, which has certain advantages. Because it is a single directional system, it might be less complicated and less expensive. And you minimize some shifting time at the bottom of the stroke because you just released the servomotors and the ram reverses.

 

A lot of these belt or block-and-tackle drives also distribute bending load across the entire ram. Every time a belt is fed over a pulley, it’s like a 10-time reduction in the gear ratio. This can create big performance advantages for electric brakes when compared to hydraulic brakes.

 

The sweet spot for these electric brakes is the lighter tonnages. If you look at the conventional machines on the market, you will see a segment of equipment in the 100-ton or less range; that’s good for the electric and hybrid type of presses. At 100 tons and higher, an electric press brake requires plenty of kilowatts to generate the force necessary to do the job. At that point, any energy savings that the electric press brake generated when compared to a hydraulic brake is negligible. Simply put, you can’t get energy for nothing.

 

So how do you transfer the force from the drive to the press brake? The three concepts are the central drive, the dual drive, and the distributed drive.

 

The central drive is more cost-effective. It’s simple. It’s limited to basically center or near-center bending. You don’t have offset capabilities with the center drive system.

 

The single drive system does provide some advantage with machine deflection. If the ram is pushing down at the center of the upper beam and the lower beam is supported on the side frames, you get a deflection pattern at the center of the bend.

 

For a dual-drive system, which is conventional technology in today’s metal fabricating world, when you start forcing the ram down, the deflection in the center of the machine has to be compensated for. Press brake manufacturers address this deflection in many ways that might be worthy of an article on its own.

 

The distributed drive is a hybrid between the center and the dual drive in which the drive cylinders are moved in just a little bit from the side of the machine. This creates parallel deflection compensation. You can compensate a little bit for the machine flex by where you put those drives.

 

With the distributed drive, the load is spread across the entire ram. Practically no deflection on the ram is the result.

 

Bed Crowning

Crowning is how a press brake compensates for machine deflection.

 

Most of the machines have some sort of mechanical deflection device on the machines. Wedges and hydraulic cylinders are used to compensate as the load increases.

 

In closed-loop systems, the center of the brake is actually under CNC as well.

 

Tool Setup

The setup time on most press brakes is equal to the tool change time. Working under the premise that a program is done offline or that a job is being rerun, a press brake should have downtime only when an operator is changing out tools for the next job.

 

The most cost-effective means to address quick tooling changeover is to use tooling designed to be placed in and removed from the ram easily. The most common types of tools that fit this description are push-button or click tooling.

 

A push-button in the front of the tooling keeps the tool from falling out of the ram. A hydraulic cylinder not only clamps the tool, but seats it; clamping and seating the tool are done simultaneously. A high-precision tool setup can be done very quickly.

 

There is a weight limit on that click. When a segment gets above 30 lbs., the tool needs to be end-loaded. Many fabricators purchase smaller segments of the tool to stay under the 30-lb. limit, so all of the tools can have the clicks.

 

Bending Speed

Bending speed is the hot-button topic today in fabricating circles. A typical press brake, maybe 5- to 10-year-old technology, can make around 600 bends per hour if it is running at top speeds. A high-dynamic press brake, such as an electric brake, can make up to 900 bends per hour. That’s a significant improvement.

 

It’s important to note that the machine is bending only a certain amount of time, however, say 20 percent of the time during a shift.

 

Using a batch size of 25 as an example, you are looking at five minutes for setup; five seconds to pick and place the part; five seconds to bend; five seconds to reposition; five seconds to bend, until the part is finally put in the stack. The total production time might be 20 minutes, but the bending time is only six minutes, which is right around 30 percent of total time.

 

So what is the advantage of the high speed? It’s with the small parts. If you have a standard machine and a high-speed machine working on small parts, the high speed really has a tremendous advantage.

 

But as parts get bigger, it could take several minutes to turn and bend them. A fab shop can have a machine that is infinitely fast, but the throughput is minimized because of the extra material handling time.

 

Stroke Optimization

Stroke optimization is the next important discussion point in bending technology. A press brake can go only so fast before it starts to lose accuracy and performance quality.

 

In some European countries, the press brake can’t go beyond a certain threshold for safety reasons. The solution is to live with a fixed speed and find ways to optimize that speed and improve the number of bends per hour.

 

With the focus on stroke optimization, you will be seeing press brakes capable of up to 1,000 bends per hour without increasing the machine speeds.

 

Part Design

CAD systems, such as SolidWorks® and Pro E®, give any person the ability to draw a hole anywhere on a part—even when they shouldn’t be placing the hole there. You can tell the part designer that a hole shouldn’t be so close to the bend line, but the designer thinks that if the CAD software allows it, then it should be possible.

 

Using this example of putting a hole too close to a bend line, you can try and resolve the potential blowout with a rotating V-die set. Rotating supports in the die allow the bending process to mimic a folding operation. The result is a clean bend because the sheet metal is supported throughout the bending process. These types of tools also greatly improve the accuracy because the part is not allowed to move in the die.

 

The other solution is to solve this problem with software. Software can identify where the blowouts are going to be, and hopefully the part designer can move the hole to avoid the blowout.

 

Of course, nothing trumps experience. If the part designer has bending experience, he knows that a relief cut can be introduced to the bend line. This slit eliminates the deformation before the part hits the shop floor.

 

Automatic Tool Changing

Automatic tool changing is being found on more press brakes today, and this technology is making the biggest impact on shop floor operations.

 

The advantage is that tool changing is happening while the operator is doing other tasks. Normally the operator has to get some blanks, log in and out of a job order, take care of paperwork, set up bins around the brake, and set up support arms. While the operator is doing that, the tool changes are being done for him.

 

The hardest thing about running a press brake is the setup. Once the machine is set up, anyone can run the machine. The new controllers show inexperienced operators how to handle the part. Some of the machines today even project a video image on the ram right in front of the operator’s face, so there is no need to look to the side monitor.

 

The press brakes that have the automatic tool changing option come with different magazine styles for the tool changer. Some are located in the rear behind the backgauge. Some are located to the side of the press brake. Some are located behind the bending window, but along the side of the frame. These arrangements create different-sized footprints for the machines.

 

Automatic Angle Correction

Automatic angle correction addresses springback that occurs in certain hard-to-bend material. The value of this type of system is that you don’t lose time trying to achieve the desired angle. There is no need for repeated cycles of bending and releasing while hunting for that angle.

 

In press brakes with this type of angle correction, the ram drives the sheet metal into the die to achieve the angle in the loaded position. Whether the punch is long or short, the V die is large or small, the material is thick or thin, the loaded angle is maintained. When the ram releases and retreats, the sheet metal reverts to a rested state, with springback likely affecting a change in angle from that achieved under load. Lasers or sensors measure the current angle, and the control software determines just what sort of restrike is needed to achieve the desired angle. Typically after the restrike, the part meets customer specifications.

 

Human-Machine Interface

Modern controls have made it possible for North American fabricators to compete with cheap labor in other countries. A fab shop doesn’t need a $50-per-hour press brake operator to produce complex parts, which is good because that fabricator can’t sell those parts for $20 any longer. Today those parts go for $2 apiece. Modern controls make it so an operator with limited experience can follow the bending sequence on the monitor and produce a part with several bends in a respectable amount of time.

 

These controls also make it simple to program a job. Even though it makes more sense to put these programs together offline, away from the machine, many shops still program at the press brake. So how simple is it? The operator plugs in the parameters of the job and then drags his finger across the screen to create a profile shape. The control software takes that profile shape and produces a bend sequence to create it. The only thing left to do is assign a part number to the job. No one is figuring bend speed, bend allowance, or the correct backgauge height. When the program is generated, the operator just follows the instructions.

 

There was a time when people were required to know much more about the bending process and metal properties if they wanted to be successful press brake operators. Now a lot of that knowledge is contained in the control software. Operators just need to be engaged in completing jobs in an efficient and timely manner. That approach gets parts to the customer by deadlines and results in positive customer relationships.

 

Modern press brakes have evolved to keep up with the need for quick turnaround of parts. They are creating competitive advantages for metal fabricators that older press brakes simply can’t match.

Something You Should Know About CNC Equipment

CNC machines are electro-mechanical devices that manipulate machine shop tools using computer programming inputs. Did you know? The name “CNC” actually stands for Computer Numerical Control and it represents one of two common methods to generate prototypes from a digital software file.

 

The first CNC equipment was developed in the 1940s and 50s and relied on a common telecommunication data storage technology known as “punched tape” or “perforated paper tape.” Punched tape technology is long obsolete as the data medium quickly transitioned to analog and then digital computer processing in the 1950s and 1960s.

 

How Does CNC Equipment Works:

 

Machining in general is a way to transform a stock piece of material such as a block of plastic and arrive at a finished product (typically a prototype part) by means of a controlled material removal process. Similar to the other prototype development technology, FDM (3D printing), CNC relies on digital instructions from a Computer Aided Manufacturing (CAM) or Computer Aided Design (CAD) file like Solidworks 3D. The CNC machine interprets the design as instructions for cutting prototype parts. The ability to program computer devices to control machine tools rapidly advances shop productivity by automating the highly technical and labor intensive processes. Automated cuts improve both the speed and the accuracy with which prototype parts can be created – especially when the material is critical (such as is the case with polypropylene – read more about polypropylene).

 

Oftentimes machining processes require the use of multiple tools to make the desired cuts (e.g. different sized drill bits). CNC equipment commonly combines tools into common units or cells from which the machine can draw. Basic machines move in one or two axes while advanced machines move laterally in the x, y axis, longitudinally in the z axis, and oftentimes rotationally about one or more axes. Multi axis machines are capable of flipping parts over automatically, allowing you to remove material that was previously “underneath.” This eliminates the need for workers to flip the prototype stock material and allows you to cut all sides without the need for manual intervention. Fully automated cuts are generally more accurate than what is possible with manual inputs. That said, sometimes finishing work like etching is better accomplished by hand as well as simple cuts that would require extensive design work to program the machine for automation.

 

Want to learn about the different types of CNC equipment? Read more below.

 

Types of CNC Equipment:

CNC machines typically fall into one the two general categories: conventional machining technologies and novel machining technology:

 

Conventional Technologies:

 

  • Drills:

Drills work by spinning a drill bit and moving the bit about and into contact with a stationary block of stock material.

 

  • Lathes:

Lathes, very much the inverse of drills, spin the block of material against the drill bit (instead of spinning the drill bit and putting it into contact with the material). Lathes typically make contact with the material by laterally moving a cutting tool until it progressively touches the spinning material.

 

  • Milling Machines:

Milling machines are probably the most common CNC equipment in use today. They involve the use of rotary cutting tools to remove material from the stock unit.

 

Novel Technologies:

 

  • Electrical and/or Chemical Machining:

There are a number of novel technologies that use specialized techniques to cut material. Examples include Electron Beam Machining, Electrochemical machining, Electrical Discharge Machining (EDM), photochemical machining, and Ultrasonic machining. Most of these technologies are highly specialized and are used in special cases for mass-production involving a particular type of material.

 

  • Other Cutting Mediums:

There are a number of other novel technologies that use different mediums to cut material. Examples include laser cutting machines, oxy-fuel cutting machines, plasma cutting machines, and water-jet cutting technology.

 

Materials Used:

Almost any material can be used in a CNC equipment. It really depends on the application. Common materials include metals such as aluminum, brass, copper, steel, and titanium, as well as wood, foam, fiberglass, and plastics such as polypropylene.

 

Application for Rapid Prototyping:

CNC equipment was the first major break-through in the field of rapid-prototyping. Before numerical control (in the case of punched tape technology) and computer numerical control (with analog and digital computing), parts had to be machined by hand. This invariably led to larger margins of error in end prototype products and even more so if/when machines were manually used for larger scale manufacturing.

 

Application for Manufacturing:

Many novel CNC specialty machines are built specifically for niche manufacturing processes. For example, electrochemical machining is used to cut highly durable metal products not otherwise feasible. Conventional CNC equipment is more adept at and typically used for prototype development than manufacturing.

 

By the way, when mentioned CNC equipment, I recommend that you can try to visit the website of SEHO Industry Co., Ltd. if you need more information about CNC machinery. SEHO is the professional supplier of specializing in new or used CNC machinery.

No Machines Are Called Shoe Manufacturing Machines?!

Someone will need to buy shoe-manufacturing machines to make sandals, heels, and boots. However, they don’t know what they are called because running a “shoe making machine” query on Google simply isn’t working. In this article, I will tell you something about “shoe manufacturing machines”.

 

First and Foremost, There is No “shoe Making Machine” As Such.

 

Shoes are made on several machines including gluers, injection molders, sole makers, toe binders, riveters, upper stretchers, lasts, heat curing ovens, sewing machines, and more. There’s no one machine where you dump in plastic pellets, a square of leather and a buckle and a perfectly finished sandal is spit out the other end. There are lots of steps-each step requires a different machine and there’s some hand work too. Rivets are set by a worker using a riveter. Uppers are sewn by a skilled operator on a special sewing machine designed for sewing uppers. Soles are glued down and cured in a heat treater. So the machines you see are used for making shoes -even if they aren’t called “shoe manufacturing machines

You might want to become a bit more familiar with the tools, words and terminology and machines used in making shoes. Several fashion colleges have programs for shoe and footwear design starting with design and moving into making shoes and manufacturing processes. You will learn the way they are made and the correct words for each step in manufacturing. Speaking of words -change your search terms: you will have better luck searching for footwear manufacturing equipment and supplies. Again you will find injection molders, sewing machines, heat treaters, cement lasters, leather cutters, skivers, lasting equipment, belt solers, sanders, and band saws, welt stitchers, and more. While none are called “shoe making machines” all are integral parts of the process in footwear manufacturing.

 

To start you might want to learn custom shoemaking – this is far more doable with less investment. You can start by getting a job in a shoe repair shop and learning the equipment, how it works, what tools are essential (lasts are the most important piece of equipment and/or tool used in making shoes) what goes into making high quality shoes, and how to make and repair shoes. Or look for a custom footwear maker/seller and work there. Learning from a master is a time honored method of learning a skill. When you know what you need from seeing what the master crafts-person uses you can find the specific machinery you need.

 

Find Out The Right and Suitable Shoe Making Equipment

 

There are courses in custom footwear and shoe-making -these will help you get a handle on the tools, machinery and the process used in making higher quality footwear. Custom shoe-making can be done in an artisan workshop setting: high fashion shoes and boots made mostly by hand in small quantities can be sold for higher prices and for high profits -and with time you can start to make a name for yourself the same way people like Ferragamo and Louboutin started. Again you won’t find anything labeled “shoes making machine” but you will find lasters, stitchers and more and you will know why these machines are what you are looking for.

 

MINZ Inc. divided shoe making equipment into three parts, one is shoes cutting machine including plane type cutting machine and traveling head type cutting machine, another is cutting machine energy saving system, and the other is automation development equipment. Their average energy saving is 70~90% comparing to traditional power system. When the machine is not cutting, it generates zero noise, and the temperature of hydraulic fluid and motor are reduced half.

How to Use a Tool Grinding Machine

Tips! Do you know what you’ll need when you use a tool grinding machine? Tell you some essential tools below:

 

  • Heavy Work Gloves
  • Tool And Cutter Grinder Machine
  • Tools To Sharpen
  • Safety Glasses

 

 

Usage of Tool Grinding Machine

A tool and cutter grinder is used to sharpen the edges of tools that have gone dull. The tool grinding machine is not a toy and takes special care and training in order to operate correctly. The tool and cutter grinder is also a rather large machine found in machine shops. It is recommended to take your tools to a professional to grind and sharpen them. The following article will explain how a professional operates a tool grinding machine.

4 Steps to Correctly Use Tool and Cutter Grinder

Step 1 – Prime the Machine

It is always a good idea to turn the tool and cutter grinder on to warm it up. A cold grinder will create rough cuts while a warm or hot grinder disc will produce the best result. Allow the tool grinding machine to run for several minutes before taking tool to the grinding disc.

 

Step 2 – Safety Precautions

Just looking at the tool grinding machine suggests a medieval torture device. There is a lot of moving parts, guides and rails to worry about as well as the grinding disc itself. Always wear heavy work gloves when using the machine. You also need to wear safety goggles. The grinding disc is typically abrasive and made with diamonds. When grinder begins to sharpen the tool it can cause small fragments of the tool, the disc or sparks to fly toward your face. Getting any of these superheated fragments in your eye can be very dangerous.

 

Step 3 – Examine the Tool

Not all tools are made the same and it is important to examine the tool you are about to use the tool grinding machine on. You are looking for the angle of the tool, including which way the blade is curved, how the edges are cut and the contact points. This is incredibly important because to properly use the tool and cutter grinder you need to know what direction the tool needs to go. If you fail to do this, you can severely damage the tool you are trying to bring back to life.

 

Step 4 – Using the Tool Grinding Machine

Double check all of your safety areas and examine your clearance. The kind of tool you are using will determine what the settings need to be. For this information you should always consult the instruction manual that came with the machine you have access to. Not every tool grinding machine is the same when it comes to this. Turn the machine on and keep a safe distance from the grinding disc. Remember the curvature of the tool you are sharpening and place it against the grinding disc at the appropriate angle. A knife, for example, would be approximately 45 degrees. Use short movements and firm pressure until you are satisfied it is sharp.

Before Buying A Surface Grinder, Something You Need to Understand

The surface grinder you need will depend largely on the material that needs grinding. For instance, if any metal surface needs grinding, the grinding wheel should be made of a highly abrasive material, and it should have numerous cutting niches embedded in it. On the other hand, for grinding a wooden surface, what you need is a lesser abrasive wheel.

 

The Types of Surface Grinder

 

There are two basic types of surface grinders, and they are:

 

  • The Planer-type
  • The Rotary-type

 

In the Planer-type, the grinding wheel remains stationary, while the worktable moves in a back-and-forth motion. This movement is controlled either manually or through some hydraulic drive system. These grinders are selected when overall grinding is required once the machine component has left the foundry.

 

In the Rotary type, the grinding wheel rotates, as does the circular worktable. These rotary surface grinders are selected when the precision machine parts require grinding, before being fitted into its housing. In both the surface grinder types, the safety hazards are well taken care of, and because of this, accidents rarely happen.

 

Things to do After a Surface Grinding Job Is Over

 

After a surface grinding job is over, the entire work station should be cleared of debris. If the work was done on a wooden material, the saw dust may be supplied to those who make composite boards, while the shavings from the metal surface can be sent to steel mills for melting.

 

However, what matters most is the safe clean-up of the work area, as otherwise, someone might get injured from carelessly thrown bits of metal shavings. Also, the surface grinder needs attention after each operation. It should be checked for any flying debris that blocks its air vents or any damage caused to the moving parts.

 

TONG YI Machinery Inc. is the outstanding rotary surface grinder manufacturer in Taiwan. If you need more information about kinds of surface grinding machines, welcome to visit their website and feel free to send inquiry or contact with them.
