Maching of NPTF thread milling cutters

Maching of NPTF thread milling cutters

Development and application of thread milling cutters:

As a method of machining thread by CNC machine tools, thread milling is first popular in Europe and America. After that, with the development of CNC machine tools in China, it has gradually been accepted and loved by Chinese customers. Thread milling is accomplished by means of the three-axis linkage function of the CNC machining center machine and the G02 or G03 helical interpolation command. The thread milling method itself has certain natural advantages. 

Since the current thread milling cutter is made of cemented carbide or other special alloys, the processing line speed can reach 80-200m/min, and the processing speed of high-speed steel cone is only 10~30m/min, so the thread milling cutter is suitable for high speed. The surface finish of the machined and machined threads is also greatly improved. Threading of high-hardness materials and high-temperature alloy materials, such as titanium alloys and nickel-based alloys, has always been a difficult problem, mainly because high-speed steel wire cones have a shorter tool life when machining the above-mentioned material threads, and use hard alloy thread milling. Knives for hard material threading are an ideal solution. The machinable hardness is HRC 58-62. For threading of superalloy materials, thread milling cutters also exhibit excellent processing performance and an unexpectedly long life. For threaded holes of the same pitch and different diameters, it takes a lot of tools to complete the tapping, but if you use a thread milling cutter, you can use a tool. After the tap wear and the thread size of the thread are less than the tolerance, it can not be used continuously, and can only be scrapped; when the thread milling cutter is worn and the threaded hole size is smaller than the tolerance, the necessary tool radius compensation adjustment can be performed by the numerical control system to continue. Threads of acceptable size are machined. Similarly, in order to obtain high-precision threaded holes, it is much easier to use a thread milling cutter to adjust the tool radius than to produce high-precision taps.



ADVANTAGE:
1. When machining large threaded holes, the wire tapping efficiency is low, and the thread milling cutter can be realized instantaneously.
2.The thread milling cutter cuts into powdery short chips, and there is no possibility of wrapping the knife. The wire tapping is processed into spiral iron filings, which is easy to wrap the knife.
3. thread milling cutters are non-total tooth contact cutting, and the machine load and cutting force are smaller than the wire tapping.
4.The clamping is simple, the tapping requires a flexible tapping shank, and the thread milling cutter can be used with ER.HSK. Hydraulic
