Solid Carbide Gear Hob Cutters Tool Golden Color Ti-Al-XN coating

 Solid Carbide Gear Hob Cutters

Coated tools have become the symbol of modern cutting tools, and the proportion of use in tools has exceeded 50%. Various tools used in cutting, including turning tools, boring tools, drills, reamers, broaches, taps, thread combs, rolling heads, milling cutters, forming tools, gear hob and gear shapers, etc. A coating process is used to improve their performance.

There are four types of coated knives: coated high-speed steel knives, coated carbide knives, and coated knives on ceramic and superhard material (diamond or cubic boron nitride) inserts. But the former two types of coated knives are used the most. The coating on ceramic and superhard material inserts is a material with a lower hardness than the substrate. The purpose is to improve the fracture toughness of the insert surface (can be increased by more than 10%), reduce the chipping and breakage of the insert, and expand the scope of application.
New coating technology
The new Ti-Al-XN coating technology is to use vapor deposition method to coat the surface of high-strength tool substrate with a few microns of high hardness and high wear resistance refractory Ti-Al-XN coating, so as to reduce tool wear and prolong life. The purpose of increasing cutting speed. It is an important achievement achieved by the national major special project of high-end CNC machine tools and basic manufacturing equipment.
