Victor Taichung Sees 70% of Orders for Customized Machine Tools

Posted on by

Taiwan-based machine maker Victor Taichung Machinery Works has coped with waning competitiveness in prices for the export markets by offering customized manufacturing services to create product differentiation, with around 70% of orders associated with customization, according to company chairman MH Huang.

 

Huang said that Taiwan machine tool makers used to see their quotes some 30-40% lower than those offered by their biggest competitors from Japan, but such a price competitiveness has been significantly undermined by the sharp depreciation of the Japanese yen. As a result, international customers have turned to Japan machine tool brands, directly squeezing the survival space for Taiwan makers.

 

Huang said that since 2013, Victor Taichung has maintained a customer value-creating application center, gathering the firm’s experienced sales staff and engineers to directly face customers and respond to their actual needs. This way, Victor Taichung can agilely adjust its product development strategies based on direct responses from customers, thus effectively boosting product values and customer loyalty through customized production services.

 

Huang stressed that Taiwan machine tool makers cannot compete well with China and Korea rivals in terms of production volume of low- to medium-tier models or with Japan makers in the market for high-end products. Accordingly, he indicated, it will be a major challenge for business transformation of Taiwan machine tool builders as to how they can work out differentiation to highlight corporate values and even develop the market for higher-end products.

Buying a Five-Axis: Selecting the Right Machine

Posted on by

Horizontal or vertical? Trunnion or swivel head? What’s the effective difference between different configurations of five-axis machining centers?

 

Not all 5 axis machining centers are alike. Here’s where the application for which they will be used must be considered. You need to know what cutting speeds you’re going to run, for example. The type of spindle, the arrangement of rotary axes, rapid traverse rates, feed rates and available horsepower are other major considerations. Do you intend to machine primarily aluminum, stainless steel or titanium? How rigid does the machine need to be? What surface-finish quality do you require? What part accuracy are you trying to achieve? These are all questions you’ll need to answer in order to select the right machine for your application.

 

If you’re primarily machining aluminum, you may prefer a spindle capable of higher speed, such as 20,000 rpm, with higher rapid traverse rates, especially if you’re using smaller-diameter tools. Likewise, if you’re machining stainless or alloy steel for complex mold surfaces, you will likely be using small tools and high spindle speeds to achieve exceptionally smooth surface finishes.

 

Be aware that some machines are designed for cutting only aluminum. Others are suitable for steel and tough alloys, which require more rigidity, higher horsepower, lower spindle speeds, slower rotary speeds, higher torque and stronger box ways to make deep cuts with bigger tools. Machining different grades of steel, titanium alloys or even harder materials may require a heftier machine; however, this hefty machine would need to rotate the table excessively fast to achieve adequate surface speeds for cutting aluminum. The result might be disappointing.

 

When specifying out a five axis machining center, obtaining the expert advice of an experienced engineer is recommended.

 

Horizontal or Vertical

Horizontal five-axis machines are normally equipped with an automatic pallet changer (APC) ready to be installed on the shop floor. If you’re machining aerospace components that have deep pockets or waffling designed to reduce finished-part weight, the high volume of chips will naturally drop into the conveyor. In addition, horizontal five-axis machines tend to be heavier and more rigid, which helps when cutting steel and titanium.

 

In contrast, vertical five-axis machines tend to be more agile for processing smaller parts. VMCs tend to enable better operator access and can often take heavier cuts, but clearing chips can be inconvenient. High-pressure, through-the-spindle coolant delivery comes in handy to remedy chip accumulation.

 

Swiveling-Head or Trunnion Style

There are pros and cons to different types of machine designs. If you’re loading heavy parts, the non-tilting table on a swiveling-head machine is often preferred, because this type of table offers greater rigidity for holding big, heavy parts. The swiveling head enables the use of shorter, standard tooling, because all tool rotations occur above the part. Swiveling-head machines tend to be more versatile, lending themselves to using multiple fixtures, vises or tombstones. This somewhat simulates the appeal of an HMC.

 

A trunnion-style machine is often preferred in moldmaking, because both rotary axes are contained in the trunnion table itself and the spindle head is stationary. This configuration is similar to that of the three- or four-axis machines most moldmakers are already used to. The spindle head reaches out over the tilting table, providing better undercut capabilities and some access to the underside of the part. As the spindle head itself does not rotate, trunnion-style machines tend to be more effective in heavy chip removal and can use full X, Y and Z travels to accommodate large parts.

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

Posted on by


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.”

Main Features and Benefits of CNC Milling Machine

Posted on by

CNC (Computer Numerical Control) milling machine is one of the common machine tools in machinery industry. It is the popular form of CNC that can perform those repetitive tasks of drilling and turning that used to be human jobs long time ago.

 

CNC Mills are classified based on the number of axes that they have. Axes are labeled as x and y for horizontal movement, and z for vertical movement.

 

Basically, this milling machine has four axes which are Milling Head Z, Table Z, Table Y, and Table X. The quantity of axes it has is often presented in many different ways.

 

For example, there is a five-axis machine. The extra 5th axis is in the form of a horizontal pivot for the milling head that ensure the excellent flexibility of machining with the end mill at an angle follow the table.

 

It is usually programmed by using a series of standard commands that we named it as G-codes to represent specific CNC tasks in alpha-numeric form.

 

There are many different sizes for this machine based on the purpose and location of usage, as well as the materials that need to be cut.

 

Besides that, the size of motor affects the speed of cutting the materials. Normally, materials like plastic and wood are the easiest things to cut, unlike steel that need stronger milling machine and longer time.

 

To evaluate the performance of milling, we can look at its rigidity. For example, the more rigid a mill is, the more precisely it drills and cuts. CNC mills normally have better & tougher engines for higher rigidity compared to manual counterparts.

 

With CNC milling machine, we can improve the speed of cut compared to manual operation. It also reduced the rejection when rigidity results increased. Thus, in long run business, it will indeed save a lot of time and overhead due to less wastage happened.

 

Another benefit is the accuracy of cut through CNC milling machine with a computer numerically controlled machine. In production line, it is very important to have all the parts produced exactly the same. However, nothing is perfect. CNC milling machine may also have a possibility of fault lies in the operator due to a mill can cut with absolute precision as close as.0001 of an inch.

 

In addition, many mills have beds that are able to move at different angles for easy cutting jobs, different angled cut as well as more difficult drilling operation. This is one of the benefits over manual mills.

 

Lastly, with the automated cooling systems, it is able to maintain the quality of raw material by spraying or blasting the hot metal or even tooling with specially formulated coolant.

 

With the benefits of CNC milling machine stated above, it is really worth the money to invest a CNC milling machine for your business use. And there are the popular brands that available in the market, such as Mori Seiki, Dahlih, CNC Takang, DMTG, Mastika, HACO, Takisawa, Okamoto, Creator, Agma, L & L, Hurco, Okuma, Extron, Enshu, Equiptop, Komatsu, Jiuh Yeh.

What Is a Swiss Lathe?

Posted on by

A Swiss lathe is a style of lathe in which the collet, or holding mechanism, is recessed behind a guide bushing. Swiss lathes are also being known as Swiss turning centers, Swiss automatic lathes or Swiss screw machines. A Swiss lathe is different from a traditional lathe in that the collet, which holds the bar stock, is not directly exposed to the tooling and bed of the lathe. This type of configuration allows this machine tool certain benefits over a traditional type of lathe.

 

The Swiss lathe’s advantages over a traditional lathe is largely because it uses a guide bushing. The purpose of the guide bushing is to provide additional support to the stock material as the part is being turned or machined. The guide bushing fits closely, but not tightly, around the bar stock material. Supporting the bar stock material, a guide bushing functions in a similar manner as a steady rest would on the carriage of a traditional lathe.

 

Swiss-style lathes generally hold better tolerances on parts because the turning operations are performed within close proximity to this guide bushing. The guide bushing provides rigidity to the turned part because only a minimal amount of stock is exposed after leaving the bushing until the turning tools are engaged. With the rigidity that the guide bushing imparts on the stock, these machines are particularly well adapted for holding tight tolerances. Another payoff is the Swiss style lathe’s ability to turn small-diameter parts or parts with large length-to-diameter ratios. Tool chatter typically is minimized because of the tool/guide bushing juxtaposition.

 

There are two types of Swiss lathe machine tools. Mechanical lathes use cams, gearing systems and mechanical linkages to move the headstock and manipulate the collet and tooling. These types of machines have been replaced in many places by computer numerical control (CNC) Swiss lathes.

 

A CNC Swiss lathe will utilize many computer-controlled components. A great number of these components can be adjusted while the machine is in operation. The advantage of a CNC Swiss lathe is that the precision of a traditional machine is maintained while the functionality of the machine is increased with the addition of a computer and its controlled components.

 

Modern types of CNC Swiss lathes might include multiple axis and live secondary tooling, moving tail stocks or secondary spindles. Depending on the desired part configuration, some Swiss lathes have the capability of turning and machining parts complete. This eliminates the need for secondary operations.

 

A disadvantage with all Swiss lathes is the bar stock remnants. These generally are longer than those found on a traditional type of lathe and generally would be considered scrap. Long remnants are the result of the configuration of the collet and guide bushing in this machine.

What Are the Different Types of Metal-working Machinery?

Posted on by

Metal-working machinery includes a wide variety of equipment used to cut and shape metal. These machines offer an alternative to shaping these metals by hand, resulting in greater precision and higher production levels. They can be found in many metalworking shops, manufacturing and industrial facilities throughout the world, as well as in the homes of hobbyists. Metalworking machines come in many forms, including lathes, milling machines, and planers. This equipment also includes basic tools used to modify the surface or finish of metal, including grinders, polishing equipment, and embossing machines.

 

Lathes are one of the most widely used types of metal-working machinery. These devices rotate a metal object around a spindle. As it rotates, tools and cutting bits shape or cut the metal into the desired form. These machines can range from small desk-top units to large floor models. While some may be manually operated, most rely on computer programming using computer numerical control (CNC) software.

 

The milling machine can be thought of as a more advanced version of the lathe. This metal-working machinery holds an object in place as the worktable moves around it. Unlike the lathe, milling machines can modify metal across three dimensions, not just two. Micro milling machines can even be used to cut and shape items that are invisible to the naked eye. Like a lathe, milling equipment generally relies on CNC software for precise control and programming.

 

A metal planer can be used to cut or shave metal in a single linear direction. These machines hold the metal object stationary, and then run a cutting blade across the surface to smooth or flatten the material. Planers can also be used to cut slots or other shapes into the face of a product.

 

Metal-working machines can also include equipment used to bend and shape sheet metal. For example, a metal brake creates folds or bends in sheets of steel and other metals. Similar machines are used to stamp or emboss patterns into metal, or to roll it flat. These machines can be either manually operated or controlled using a CNC system depending on where they are used.

 

Extruding and casting equipment are other types of metal-working machinery. In casting, workers make a mold of an object and use it to shape molten metal. Extrusion involves forcing hot metal through a die. The shape of the die determines the shape and profile of the final product.

 

SEHO provides much different second hand metal-working machinery such as CNC grinding machinery etc. machine tools. If you are interested in learning more information about used machinery, welcome to visit our website and feel free to contact with SEHO Industry Co., Ltd.
