Micromachining technology and its application

micromachining technology is a new processing technology invented by Swiss binc company to take its arithmetic average value. It won two invention awards at the international surface treatment exhibition (SIT) held in Paris, France in 2004 and the alliance exhibition held in Lyon, France in 2004. Micro processing technology and equipment have international patent protection

micro machining technology combines two innovative technologies, ultra precision brightening and ultra precision polishing, which can selectively retain the microstructure of the surface to improve the friction and sliding performance of the surface (surface technology), replace the traditional manual polishing with mechanization and automation, and improve the aesthetic function of the surface. This micro machining technology is applied to the surface treatment of cutting tools, stamping and forging tools, aviation, automotive, medical devices, plastic injection molds and other mechanical parts, which can greatly improve the surface performance of parts

principle of micro machining

micro machining technology uses a fully automatic way to ultra finish the surface of metal parts, and removes 1 ~ 40% of the surface of metal parts through a mechanochemical action μ M, and the surface roughness of the machined surface reaches or is better than the N1 level surface quality of ISO standard. Micro machining technology is mainly used in two fields: ultra precision polishing and ultra precision brightening. Ultra precision polishing automates the traditional manual polishing process; And super fine brightening generates a new surface topology

one of the outstanding advantages of micro machining technology is that it can give new microstructure to the surface of parts. These microstructures can improve the adaptability of the part surface to specific application functions. Such as reducing friction and mechanical differences, improving wear resistance, and improving the deposition performance of the surface before and after plating

in general, superfinishing and brightening can remove the secondary micro rough surface, and the thickness of the secondary rough surface is 0 ~ 20 μ M, between the peaks of the primary micro rough surface of the part surface. While superfinishing removes the primary micro rough surface partially or completely, with a value of 10 ~ 40 μ M, of course, depends on the initial state of the material surface of the part

the materials that can be processed by micro machining technology so far include annealed and quenched steel, copper and copper alloy, cast iron, Inconel nickel alloy (nickel base alloy), titanium metal, pretreatment before and after surface hard coating treatment (PVD, CVD, electroplating)

technology patent

micromachining technology China's extruder industry has many beneficial conditions in foreign trade and export. It is an innovative micromachining process that selectively refines the surface micro roughness and topological structure of the processed object. This mechanochemical processing technology is a fully automated processing technology, which is suitable for automotive manufacturing, electronics, chemical industry, metallurgy, machinery manufacturing, aviation manufacturing and other industries, especially injection mold, cutting tools and machine tools, high-precision parts, optical devices, and surface pretreatment before and after hard coating treatment

Application of micro machining technology

micro machining technology can reduce friction, improve wear resistance and significantly improve the surface properties of materials by changing the micro structure of the material surface. It has a broad application prospect in the tool industry. For example, using ultra precision brightening technology to completely eliminate the secondary micro rough surface and reduce friction can improve the chip removal performance of the tool and reduce the cutting force; Keeping the primary rough surface is conducive to protecting the lubricating oil film, improving the chip removal performance of the tool and reducing heating; If the base surface of the pretreatment coating is optimized before the coating treatment, or the rough surface caused by the coating is completely removed after the coating, the adhesion performance of the PVD coating can be improved, the surface bonding strength can be extended, the service life of the tool can be prolonged, and the problem of chip buildup on the tool surface can be eliminated. "

The practical application of this innovative processing technology in many industrial fields in recent years clearly shows that micro machining technology can significantly reduce the cost of ultra precision machining; Greatly shorten the production cycle; It is convenient to improve the quality of the surface, and the surface processed by this processing technology has unparalleled consistency and reproducibility.
