The cutting performance of the tool material is related to the durability and productivity of the tool. The processing of the tool material affects the manufacturing and blade grinding quality of the tool itself. Because tungsten carbide has better heat resistance and wear resistance than high -speed steel, it is used to use it. Therefore The tools made of tungsten carbide materials are more suitable for cutting and processing of stainless steel.
Tungsten carbide divided into two categories: tungsten cobalt alloy (YG) and tungsten cobalt -titanium alloy (YT). Tungsten cobalt alloys have good toughness. The tools made can use a larger front corner and blade to grind the sharp blade mouth. During the cutting process, the dandruff is easy to deform, the cutting is brisk, and the dandruff is not easy to stick. Therefore, under normal circumstances, it is more appropriate to process stainless steel with tungsten carbide. In particular, tungsten carbide blade should be used in the case of rough machining and disconnected cutting of large vibration. It is not as crisp as crisp as tungsten cobalt -titanium alloy, not easy to sharpen, and easy to collapse. The redness of tungsten cobalt -titanium alloy is better. Under high temperature conditions, it is more resistant to tungsten and cobalt alloy. However, its crispness is large, impact and vibration, and generally use stainless steel stainless car tools.

The cutting performance of the material is related to the durability and productivity of the tool, and the processing of the tool material affects the manufacturing and blade quality of the tool itself. It is advisable to choose knife materials with high hardness, anti -adhesion and good toughness, such as YG hard alloy, it is best not to choose YT -type hard alloys, especially when processing 1gr18ni9Ti Austenite stainless steel should be avoided. alloy. Because ti (TI) and YT -class hard alloys in stainless steel have a close -up effect, crumbs can easily take away the TI in the alloy and promote the wear of the tool. In addition, the requirements for the surface roughness of the cutting part of the tool to increase the surface smoothness of the cutting part of the tool, which can reduce the resistance when the chip is cut and increase the durability of the tool. Compared with processing ordinary carbon steel, when processing stainless steel, the amount of cutting should be appropriately reduced to reduce the wear of the tool; at the same time, the appropriate cooling lubrication should be selected to reduce the cutting heat and cutting force during the cutting process to extend the service life of the tool.
