Stainless steel tungsten steel milling cutters are coated with several micrometers of high hardness, high wear resistant and refractory material Ti-Al-X-N coating on the surface of high-strength tool matrix using vapor deposition method to reduce tool wear, extend tool service life, and improve cutting speed.

The core technology of bearing tools: machine tools are referred to as "machines for manufacturing machines". If CNC machine tools are a work of art in modern industrial civilization, then hard alloy cutting tools are diamonds on the artwork, and the light of diamonds comes from a coating several micrometers thick on the surface of the tool.
Coated cutting tools have the characteristics of high surface hardness, good wear resistance, stable chemical properties, heat resistance, oxidation resistance, low friction coefficient, and low thermal conductivity. The reason is that the coating material serves as a chemical barrier and thermal barrier, reducing diffusion and chemical reactions between the tool and the workpiece, thereby reducing tool wear, increasing tool life by more than three times, and increasing cutting speed by 20% and 100%. It can be said that the thin coating carries the core technology of the cutting tool.
At present, the proportion of coated tools in cutting tools has reached 80%. Due to the monopoly of foreign enterprises in the field of cutting tools, the status of cutting tools and their core coating technology is increasingly valued in the special projects of CNC machine tools in China, and breakthroughs in coating technology have also been included in many topics.
