With the application of tool coating technology of pvd coating machine, as the cutting speed of tools is getting higher and higher, customers have higher and higher requirements for coating quality and performance. Not only are the coatings required to have ultra-hardness and wear resistance, but also The surface finish of the tool and the surface finish of the processed products are also getting higher and higher.

        Therefore, the post-treatment process of the coating of the tool coating of the vacuum coating machine has begun to receive widespread attention.
        This technology is mainly aimed at grinding and polishing the surface of the coated tool through special equipment after coating different tools. The life of the coated tool through this treatment can be increased by 20% to 100 on the basis of the life of the ordinary coated tool. %about.
        Through this post-treatment, the micro-particle phenomenon generated during the arc evaporation process can be completely solved. As we all know, the arc evaporation process of pvd coating machines and pvd coating equipment can generate super energy, which is unmatched by any other process. The energy radiation surface generated by the arc evaporation process is extremely strong, which can make the target material highly ionized and form high Precise plasma zone, thus forming super strong bonding force, highly dense film. But at the same time, it will also produce tiny particles on the coating surface of vacuum coating machines and pvd coating equipment. Although such tiny particles can only be observed under a high-power microscope, it can be compared with the surface roughness of the tool itself. It is negligible and has no effect on ordinary normal machining. However, with the continuous advancement of science and technology, various new materials and difficult-to-process materials have been continuously applied to various high-precision fields. Users have higher and higher requirements for the quality, durability and performance of the cutting tools. Therefore, the pvd coating machine coating The surface quality requirements of layered products are getting higher and higher.
         In response to this situation, the coating post-treatment process developed by Huicheng Vacuum has completely solved the particle problem in the arc evaporation process. Especially the post-treatment of the high-aluminum-titanium film of our company’s pvd coating machine: AlTiNPT (aluminum-titanium ratio is 70/30), the film itself has super-hard, wear-resistant, and high-temperature characteristics, and after coating post-treatment , The film surface is highly delicate and smooth, which greatly reduces the cutting resistance of the tool during the cutting process, enhances the chip removal function, thereby improving the cooling effect during the cutting process, and greatly prolongs the use effect and life of the tool. At present, our post-processing technology is mainly applied to cutting tools that require high quality, such as wheel groove milling cutters in the steam turbine industry, high-speed dry cutting end mills, and cemented carbide indexable inserts. With the continuous recognition of customers, we have gradually extended this process to other taps, reamers and various mold coating post-treatments that require high quality.
