TiCN-based cermet tools have excellent performance in the semi-finishing and finishing of various steels, castings, and powder metallurgy materials, especially in the mold processing industry. Because of their good wear resistance and heat resistance, so It can maintain the sharpness of its cutting edge for a long time at high temperature, and its service life is 3-10 times that of tungsten steel.
In order to prevent repeated thermal shock from causing damage to the tool, try to choose dry cutting. Due to the relatively small thermal conductivity of cermets, most of the cutting heat generated in high-speed cutting is absorbed by iron filings, and the temperature rise of the workpiece is small, so there is no need to worry about thermal expansion and thermal deformation of the workpiece.
At present, cermet milling cutters have gradually replaced cemented carbide cutters in the field of milling and finishing. WC is the main component of cemented carbide and is considered to be a strategic material raw material. With the continuous rise of global tungsten prices, domestic high-speed precision With the increasing popularity of machining, the application range of cermet milling cutters is constantly expanding. In the near future, cermet will definitely become the mainstream material for metal cutting.
