Victor Taichung Takes Milling to The Next Level With New P76 VMC Series

Victor Taichung P76 Vertical Machining Center

High performance milling has just been taken to a new plateau with the arrival of the new P76 vertical machining center from Victor Taichung. The new 3-axis VMC only recently arrived in the UK and it is already setting new standards for performance, productivity and precision among the subcontract machining community.

 

Quality is assured with Victor Taichung and this latest addition to the stable at the Rochdale Company is the epitome of a high quality machining center. The new P76 incorporates a 30 tool ATC that can change tools in a blistering 1.6 seconds with a chip-to-chip time of 4 seconds. This speed is matched by the rapid feed rates of 48m/min in X and Y axes with 32m/min possible in the Z plane.

 

Not only does the new P76 have the facility to speed around its X, Y and Z work envelope of 760mm by 500mm by 510mm, the machine also demonstrates rigidity and stability through its BBT-40 face and taper contact spindle configuration and the certified meehanite structure that has an extremely wide base of 1166mm. Whilst the BBT spindle system enforces rigidity through the spindle nose and cutting tool to improve tool life, cutting speeds and feeds; the exceptionally wide casting base dampens vibration and adds stability. The result is the ability to conduct heavier cutting at higher speeds and feeds, which will certainly improve productivity. Furthermore, these characteristics will enhance surface finish and precision for the end user.

 

To increase material removal rates, the P76 has an 18.5kW spindle motor that delivers high torque levels throughout the speed range that reaches a top spindle speed of 12,000rpm. Accepting a maximum component weight of 500kg on its 840mm by 500mm table, the new P76 machining center is loaded with a range of standard accessories that includes a fully enclosed splash guard, FANUC 0i-MF CNC control unit with a user friendly 10.4 inch monitor and spindle oil cooler to maintain performance and longevity. Additionally, the P76 offers rigid taping, remote MPG, 3-step warning light, leveling pads, auto power-off and a screw type swarf removal system.

 

The base model of the new P76 is very well equipped to meet the demands of the modern machine shop. However, for end-users looking for a higher-specification solution, Victor Taichung can tailor the machine to the needs of the customer with optional extras that include a 40 tool ATC, coolant gun, automatic tool length measurement, auto part measuring and even a 4th and 5th axis interface. For enhanced precision and meeting the needs of high speed machining, the P76 can be configured with a 15,000rpm spindle, linear scales, rotary tables, oil skimmer, automatic doors, through spindle coolant, a Heidenhain TNC-620/640 CNC control and much more.

Horizontal Machining Center Vs. Vertical Machining Center: Is a VMC or an HMC Better?

Every year, Modern Machine Shop does studies on the machine shop industry. One of the most helpful things they do is their Top Shops report, which does a detailed breakdown of the differences between what the fastest growing and most profitable machine shops are doing compared to the “average” machine shop.

 

Horizontal Machining Center Costs and Benefits

 

The top shops had higher gross sales per machine that average shop – $266,123 versus $152,000. That is huge. One of the major differences: top shops spent 10% of their gross revenues on equipment versus 2% for average shops.

 

One place that makes a difference: invest in horizontal machining centers. You probably know that a horizontal machining center (HMC) costs more than a vertical machining center (VMC) – but do you know that 61 percent of the “top shops” invest in HMCs – and an additional 41% of them also invest in multi-face tombstones?

 

More important: an HMC can be as productive as two or more VMCs. In fact an article written by Modern Machine Shop in 2013 called “Worth Three Machines” highlighted how one company used its HMC to do as much work as 3 VMCs.

 

Review of HMCs vs VMCs

 

HMCs cost a lot more than VMCs. How much more? The Association For Manufacturing Technology says the average HMC costs $375,000 vs. just $115,000 for the average VMC. That’s why 4 times as many VMCs are bought than HMCs every year.

 

If you look at just the cost of the machine, it might make sense to purchase a VMC, but if instead of looking at the price, you look at what you get for each dollar spent, the numbers look a little different.

 

Since very few companies pay cash for their machines, let’s look at monthly payments on HMCs Versus VMCs:

 

For an easy comparison, we’ll look at a 5-year lease on each machine, assuming your company has a good credit profile.

 

  • HMC average cost: $375,000. Average monthly lease payment: $7,050 per month
  • VMC average cost: $115,000. Average monthly lease payment: $2,250 per month
  • Difference in monthly payment: $4,800 per month

 

OK, so a HMC costs, on average, $4,800 a month more than a VMC. Yes, that’s a lot more, but the real question is:

 

Will the extra profits you reap by having that HMC be more than that $4,800 a month?

 

The key driver in machine tool utilization is spindle run time. This is where HMC’s really shine. The average spindle run time on an HMC is 85% versus 25% on a VMC. So what does that mean? That means, on average, less than a third of the labor required to make the same part.

 

Whether it makes sense to invest in the HMC depends on your business model, as obviously the savings in setup times from the HMC are more important on long runs than on short runs, but if you do any long run stuff at all, the savings are pretty apparent.

 

Figure the minimum cost of a machine operator after accounting for wages, benefits, labor burden, etc. has to be roughly $6,000 a month. Since your HMC can do the work of three VMCs, it would cost $18,000 in labor to do the same work on VMCs as you get done on HMC’s.

 

True Costs and Pricing of HMC VS VMC

 

OK, yes, the example above is a little bit simplified, but doing an apple to apples comparison, it gets us “close enough” to the info we need to make a decision. With everything else being equal:

 

An HMC costs $4,800 more per month to finance than a VMC.

Using a VMC will cost you $12,000 per month more in labor than an HMC.

All other things being equal, the HMC will save you $12,000-$4,800, or $7,200 a month.

 

Let’s repeat that: after taking into account the extra monthly cost of the HMC, it will still save you $7,200 a month in labor costs.

 

As an added bonus, more expensive equipment can typically be financed for longer period of time: on the average $375,000 you would be able to finance for 7 years instead of just 5, which would drop your payment from $7,050 per month to $5,450 per month.

 

In both cases, if you lease you should be able to write off the entire payment as an operating expense, with the option to buy the equipment at the end for 10% of the original price. Another option, is an equipment finance agreement, which costs a little bit more (roughly 8% higher payments) but you would own the equipment at the end for $1.

 

The advantage of leasing over buying – tax treatment. Prior to January 2014 Section 179 of the tax code gave you a huge upfront deduction (up to $500k) when purchasing but that number has been curtailed to just $25,000 for 2014 so leasing is starting to make more sense for most companies.

 

Which Is Better?

 

The choice of Horizontal Machining Center or Vertical Machining Center depends on your business model, and some other things, but hopefully this article has given you something to chew on while making this decision.

 

If you need more information about vertical machining center and horizontal machining center, I recommend that you can visit the website of CNC-TAKANG: www.takangcnc.com.

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.”

What Are The Disadvantages of Fabric Dyeing?

Do you know how the colored fabrics get the attractive colors and in different shades? Mostly, the coloration of the greige fabrics is done in the dyeing process. I have explained different types of fabric dyeing processes in a separate article. In this post, I will show you various disadvantages of the fabric dyeing.

 

Disadvantages of Fabric Dyeing

Among the many drawbacks of fabric dyeing, the following are important.

 

Variation of shade from beginning till the end along the running length of the fabrics, thus resulting in tailing. This creates a greater number of shade lots resulting in more of color groups among the garments.

 

Variation of shade from one selvedge to the other, resulting in increasing the consumption and wastage of fabrics per meter while conversion to garments.

 

Below satisfactory packaging efficiency, below 80% in most of the mills, due to the above problems, which are just two out of the innumerable ones generated in fabric dyeing.

 

Although the cost is apparently lower in fabric dyeing, the lower packing efficiency and the higher number of reprocessing practically shoots up the fabric cost. Also, reprocessing in most cases is based on trial and error without a surety of getting the desired results.

 

What replaced fabric dyeing?

 

To overcome the drawbacks of fabric dyeing as well as to add value to the fabrics, yarn dyeing was introduced as an alternative. The advantages of yarn dyeing are:

 

Checks and stripes could be made easily which was difficult earlier. They added to the varieties of fabrics that could be made.

 

Dyeing a yarn was easier with the machines involved smaller in size and volume.

 

Reprocessing was easier with predictable results.

 

Fabric defects generated due to yarn dyeing was lesser as compared to fabric dyeing.

 

Although process cost is higher in a case of yarn dyeing as compared to fabric dyeing, the lower reprocessing rate and lesser fabric defects generated keep the fabric cost in control with more of varieties.

 

Yarn dyeing is however not a new innovation altogether; it was in fact extensively used for the purposes of surface designs, embroidery, and handcrafted textiles. The bulk operation of the same gathered momentum after fabric dyeing could not be improved beyond a certain limit in terms of efficiency.

Introduction about Types of Milling Machine

The usual classification according to the general design of the milling machines is as follows:

 

Column and Knee Type Milling Machine

For general workshop the most commonly used is the column and knee type. These machines have a single spindle only. They derive their name “Column and Knee” type from the fact that the work table is supported on a knee like casting which can slide in a vertical direction along a vertical column. The up and down movement of the table can accommodate work of various heights.

 

Plain Milling Machine

These machines are of the column and knee type and consist of a rigid frame or box structure. It consists of a table, a saddle and a knee. This gives three straight-line movements perpendicular to each other. The arbor is fixed in position, and the tool rotates while the work is fed past the cutter in a straight line. It is a useful machine for manufacturing operation involving simple, straight line cut.

 

Universal Milling Machine

A universal milling machine is so named because it may be adapted to a very wide range of milling operation. A universal milling machine can be distinguished from a plain milling machine that the table of a universal milling is mounted on a circular swiveling base which has degree graduations and the table can be swiveled to any angle up to 450 on either side of the normal position. This is advantageous when milling spirals. Thus in a universal milling machine in addition to three movement as incorporated in a plain milling machine, the table may have a fourth movement when it is fed at an angle to the milling cutter.

 

Omniversal Milling Machine

In this machine, the table having all the movements of a universal milling machine, and can be tilted in a vertical plane by providing a swing arrangement at the knee. The entire knee assembly is mounted in such a way that it may be fed in longitudinal direction horizontally. The additional swiveling arrangement of the table enables it to machine taper spiral grooved in reamers, bevel gears etc. it is essentially a tool room and experimental shop machine.

 

Vertical Milling Machine

There are two types of vertical spindle milling machines. Fixed Bed Type VS Column and Knee Type. A vertical milling machine can be distinguished from a horizontal milling machine by the position of its spindle, which is vertical or perpendicular to the work table. The machine may be a plain or universal type and has all the movements of the table for proper setting and feeding the work. The spindle head which is clamped to the vertical column may be swiveled at an angle, permitting the milling cutter mounted on the spindle to work on angular surfaces. In some machine the spindle can be adjusted up or down relative to the work.

 

Manufacturing or Bed Type Milling Machine

  • Horizontal Simplex Milling Machine:

These types of machines are production type machines and are of rigid structure which yields high production of interchangeable jobs. It has got one spindle head.

 

  • Horizontal Duplex Milling Machine:

Milling machines using the two spindles. For finishing two surfaces of casting at a time.

 

  • Triplex Milling Machine:

Milling machines using the three spindles, two horizontal and one vertical for finishing three surfaces of casting at a time.

 

Planner type Milling Machine

They are used for heavy work. Upto a maximum of four tool heads can be mounted over it, which can be adjusted vertically and traverse directions. It has a robust and constructions like a planer.

 

Special type Milling Machine

  • Continuous Feed Rotary Milling Machine:

The construction of the machine is a modification of a vertical milling machine and adapted for machining flat surfaces at production rate. The face milling cutters are mounted on two or more vertical spindles and a number of work pieces are clamped on the horizontal surface of a circular table which rotates about vertical axis. The cutters may be set at different heights relative to the work so that when one of the cutters is roughing the pieces the other is finishing them. Operator may carry out a continuous loading and unloading of the work pieces, while the milling is in progress.

 

  • Drum Type Milling Machine:

The drum type milling machine is similar to rotary table milling machine in that its work supporting table which is called a drum, rotates in a horizontal axis. The cutters are face mills and are usually roughing and finishing cutters similar to those of a rotary table miller. Fixture is mounted to the drum either on each face or on the periphery. When the work is mounted on the periphery, the operation is usually facing the two ends of the work piece to the precise length. The finished machined parts are removed after one complete turn of the drum and then new ones are mounted on it.

Vertical Turning Center: Myths vs. Reality

Vertical turning center may be most misunderstood and under-applied technology available in manufacturing today. The myth associated with vertical turning is that it is only applicable to large heavy parts. However, vertical turning brings as many advantages for small parts manufacturing as it does for large, heavy parts.

 

Target applications for vertical turning are the obvious heavy, hard-to-load workpieces requiring a crane or automation, or nonconforming part shapes that need to be fixture as opposed to traditional centralizing chucking. Additionally, fragile work pieces requiring low clamping pressures to prevent distortion also benefit from the vertical turning process. Let us not forget all the challenging parts out there with interrupted cuts and unbalanced work pieces. Therefore, if you stop for a minute and think about the applications I just outlined, the only popular turning applications I did not mention are those requiring a tailstock.

 

Taking Advantage of Gravity

So now that we have the gears turning, you may be asking yourself “what advantages does vertical turning provide that allows so many applications to benefit from it?” Before we get into the specifics, take a minute and think about how parts move through your shop. If you’re processing chucker parts, I’d guess that nearly 100% of these parts move through your shop on a pallet lying flat, and we do this because it’s the most stable way. What makes this the best way to move and store your parts? Gravity.

 

Well, gravity is the number one, largest contributor to the vertical turning process. Gravity is a constant, providing a positive downward force on the workpiece, assisting the workholding. This assists those heavy machining applications by providing additional stability especially on those delicate parts that like to resemble eggs or potato chips after machining. Minimal clamp force can be applied to these types of parts and gravity keeps the part in the chuck. I have actually machined parts and removed them from the chuck without even opening the chuck after machining. Try that on your horizontal spindle lathe – I bet you dig the part out of the chip conveyor.

 

The Advantages of Additional Support

Having the spindle vertical, as opposed to horizontal, allows the spindle to be supported 360°, eliminating spindle droop and increasing the maximum weight allowable on the spindle. The additional support also dissipates the cutting forces created by heavy and or interrupted cutting. Eliminating spindle droop also allows capabilities for achieving better part flatness and perpendicularity accuracies.

 

Ergonomic Advantage

The vertical turning center also provides a distinct ergonomic advantage by facilitating part loading. I’ve witnessed operators performing some very unsafe acts by actually placing one foot into a horizontal lathe to hold a workpiece in place on locators while closing the chuck. With the vertical lathe, an operator can simply place the part into the chuck, just like they place it onto a pallet, and close the chuck while gravity does its job.

 

Footprint Advantage

I visit shops on a weekly basis and I repeatedly hear from customers that they’re challenged with a lack of floor space. Brick and mortar is expensive. Many shops simply do not have the luxury of being able to add on to their facility, and they need to utilize every square foot available. I also see literally hundreds of horizontal lathes running chucker work and the tailstock is never used. Many machines may go their entire life and never have tailstock used. This creates another huge advantage of the vertical turning center as it normally consumes one-half of the footprints of a horizontal lathe. And more times than not, the footprint of a twin spindle vertical lathe is still either less than or equal to a horizontal lathe.

 

When you’re looking for your next turning center, I hope you consider the advantages and profitability that vertical turning center can bring to your business. If you’d like help evaluating your options, try to contact with FALCON Machine Tools Co., Ltd., they are the outstanding manufacturer of specializing in milling machines, grinding machines, and turning machines.

Flexible High-Speed Mold Machining

Molds and dies come in all different shapes and sizes, and flexible high-speed machining plays an important role in their manufacture. Double column machining centers are powerful, efficient machines with a wide range of functionalities that can give you the results you are looking to achieve.

 

If you’re in the market to purchase a double-column machine, there are several factors to consider before making an investment. Ultimately, you need to decide upon the criteria that currently matters the most to you, while also considering what your manufacturing needs may be down the road. For example, which functionalities are the most important to your large mold machining? Is it multiple attachments, tolerance control, a compact footprint or bed size?

 

Here are some of the variables that need to be considered when setting up particular specifications for your desired double column machining centers:

 

  • Vertical machining:

Vertical machining is ideal for simple work like cutting holes in large plates. Simplicity is the name of the game, so a double-column vertical machine is ideal if you don’t need five-sided functionality. With this type of system, the spindle is fixed and not easily changed out.

 

  • Five-sided machining:

Some double-columns can be configured with vertical and horizontal attachments that allow the machine to function as both a vertical and horizontal machine. If your part needs multiple-face machining, this functionality should be an important consideration. Rather than repositioning a part, the operator can machine it in one clamping, which produces a more streamlined approach to mold machining.

 

  • Five-axis machining:

This functionality allows for full five-axis part contouring. It is also useful for shape profiling and for light–to-medium cutting applications. In addition, five-axis machining allows for shorter setup times and reduced workholding requirements, which generate more complete parts per operation.

 

  • Five-axis indexing:

For heavy-duty cutting applications, five-axis indexing functionality is essential. It’s rugged and offers more powerful cutting options in one- to five-degree increments and it is ideal for process-intensive machining such as mold making. This type of machining improves accuracy, reduces tool change time and can yield significant increases in productivity.

 

  • Tolerance control:

Consider the type of tolerances your parts require, and then look for a machine that offers options or enhancements on tolerance. High speed and accuracy are essential for increasing throughput, and with today’s technology, you should not have to choose between the two. You can achieve high speeds without sacrificing quality, and a throughput advantage will give you a competitive edge in the marketplace.

 

  • Enclosures:

Double columns are massive machines, so running them in the safest manner possible should always be a priority. Most people think enclosures are solely used to maintain operator safety, but they also keep the manufacturing area clean and neat. Jobs are contained, as coolant is prevented from spraying and chips from flying. Enclosures are mainly used for containing the bed however, rather than the entire machine.

 

  • Bed size:

The size of the parts to be machined will determine bed size. As mentioned earlier, be sure to consider your current and future needs, as beds cannot be changed out. Carefully pick a bed large enough to access all sides of the parts that you’re cutting, especially if you will be manufacturing a part that requires multiple-face machining.

 

Lastly, it may be a smart to consider a double column machining center that is built specifically for your needs and desired functionalities. An off-the-shelf solution may not be the best fit. Weighing the benefits of the available functionalities will help you decide which machine is best-suited for your mold making needs, both today and tomorrow.

HMCs – Machining On Five Axes

Modern commercial machining can be accomplished in a variety of ways. Simple jobs, such as perpendicular drilling, can still be processed with a manually operated machine. Even a fairly complicated component can be produced with the primitive computerized numerical control (CNC) machine tools of the 1980s.

 

Some Modern engineers and designers, however, are constantly pushing the machining envelop by imagining ever more complex designs. The components described by these complex designs often require a 5-axis CNC horizontal machining center (HMC) in order to be performed to the proper tolerances.

 

What is a 5-axis CNC horizontal machining center? It is a state-of-the-art computer-controlled milling machine. Actually, its name alone does a fairly decent job of describing its major attributes. Horizontal refers to the orientation of the main spindle. Vertical machining centers do exist and, although less expensive, are sometimes considered inferior in precision and capability.

 

The 5-axis refers to the ability of the machine to physically manipulate the component and of the cutting head. The X, Y and Z axes are the normal axes familiar to everyone: up and down, side-to-side and rotational movement. In addition, movement along a C-axis is asymmetric and allows for eccentric turning. Lastly, the B-axis allows for the tilting of the machining head itself. Computer control of these movements allows for the creation of almost any shape.

 

CNC refers to the computerized numerical control of the machine. A computer controls all aspects of the process. It rotates the component on the five axes, controls the depth of cuts and bores and automatically determines the correct tool necessary. This last feature is accomplished through the use of a magazine that houses a wide variety of tools. A typical magazine will hold a drill, lathe, plane, screw tap, gear shaper and many other dies.

 

The Rigid construction of the device is another key feature that allows it to produce the most complicated components within the specified tolerances. But without the proper materials and bracing, the entire machine would flex and ruin the accuracy of the tooling.

 

All of these features allow for the production of components to a tolerance of 1/10,000 of an inch while maintaining greater efficiency and productivity.

 

Horizontal machining centers are feats of engineering and they are interesting to witness in action. It takes the skill of a human to imagine and create the programming that allows these wonders to do their work.
