(1) Improve the oxidation resistance temperature of the tool surface.

(2) Significantly reduce the coefficient of friction, physical vapor deposition PVD coating technology, significantly improve the hardness and wear resistance of the tool surface, can withstand higher cutting temperature carbide rotary file, alloy grinding head, tungsten steel grinding head, While the surface hardness is improved, the substrate has sufficient toughness; therefore, it has broad application prospects. At present, CNC machine tools have been widely used in the cutting process of coated carbide rotary files, alloy grinding heads, tungsten steel grinding heads; commonly used coating technology There are two types of physical vapor deposition (PVD) and chemical vapor deposition (CVD), which are conducive to reducing the thermal wear of the tool. The commonly used coating materials are carbides, nitrides, carbonitrides, oxides, borides, silicides, Sulfide, diamond and diamond-like carbide more than 10 kinds of carbide rotary files, alloy grinding heads, tungsten steel grinding heads, the most widely used carbide matrix materials are TiC, TiN, Al2O3, TiCN, TiAlN and their composites Coating and other hard coating materials, and make dry cutting possible. Due to the low deposition temperature of cemented carbide rotary files, alloy grinding heads, tungsten steel grinding heads, the impact on the base material is small. The excellent performance of the coating is mainly manifested as:

(3) Yuyao Ji Ting Cutting Tool Factory guarantees the impact toughness of the tools, and at the same time, the carbide rotary files, alloy grinding heads, tungsten steel grinding heads, and coated carbide cutting tools are on the carbide substrate with better toughness. Improve the cutting function, improve the processing efficiency and life. Carbide rotary file, alloy grinding head, tungsten steel grinding head, good chemical stability. Improve the friction and chip removal ability of the tool surface, and coat a few micrometers to tens of micrometers with a high wear resistance refractory metal compound or non-metal compound, which better solves the hardness and wear resistance of the tool material The contradiction between toughness and toughness, the coating can be a single coating or a composite coating, which combines the advantages of high strength and high toughness of the substrate, high hardness and high wear resistance of the coating, so the application of cemented carbide rotary files is becoming more widely used. , Alloy grinding head, tungsten steel grinding head.
