Carbide End Mills Cutter type
Commonly used CNC milling cutter
Now several of the more commonly used types of milling cutter on its application to illustrate.
(A) single-blade cutter
The tool processing efficiency is high, the use of high-quality carbide for the body, the general use of cutting edge sharp grinding process, and high-capacity chip removal, the tool in the high-speed cutting in the non-sticky, low heat, high finish. It is widely used in handicrafts, electronics, advertising, decoration and wood processing industries, suitable for factory batch processing and high demand products.
(2) two-edged end mills and four-edged end mills
This type of tool is generally used in the overall alloy structure, which is characterized by a strong stability, the tool can be a solid work in the processing surface, so that the quality of processing can be effectively guaranteed. Applicable materials, such as carbon steel, die steel, alloy steel, tool steel, stainless steel, titanium alloy, cast iron, suitable for general mold, mechanical parts processing.
(3) thread cutter
With the development of CNC machine tools in China, thread cutter is getting more and more recognized, it is a good processing performance, become a lower thread processing costs, improve efficiency, to solve the thread processing problems of powerful processing tools. As the current thread cutter manufacturing materials for the carbide, the processing line speed of up to 80 ~ 200M / MIN, and high-speed wire cone processing line speed of only 10 ~ 30M / MIN, so the thread cutter for high-speed cutting, processing thread The surface finish also increased significantly. High hardness materials and high temperature alloy materials, such as titanium alloy, nickel-based alloy thread processing has always been a more difficult problem, mainly because the high-speed steel taper processing of the above material thread, the tool life is short, and the use of carbide drilling Knife for the hard material thread processing is the effect of the ideal solution. Machinable hardness of HRC58 ~ 62. For threading of high temperature alloy materials, thread milling machines also show very excellent processing performance and longer than expected long life. For the same pitch, different diameter of the threaded hole, the use of tap processing need to more than the tool to complete, but if the use of thread cutter processing, the use of a tool can be. In the tap wear, the processing thread size is less than the tolerance can not continue to use, can only be scrapped; and when the thread cutter wear, processing screw hole size is less than the tolerance, the CNC system through the necessary tool radius compensation adjustment, you can continue Machined size qualified thread. Similarly, in order to obtain high-precision threaded holes, the use of thread cutter to adjust the tool radius of the method, than the production of high-precision tap is much easier. For small diameter thread processing, especially high-hardness materials and high-temperature materials in the thread processing, the tap sometimes break, plug the threaded hole, and even scrap the parts; the use of thread cutter, the diameter of the tool is smaller than the processing hole, even broken The use of thread milling, compared with the tap, tool cutting force significantly reduced, which is large diameter thread processing, is particularly important to solve the machine load is too large, it is not easy to remove the screw hole, Can not drive the tap processing problems.
