Micromachining technology and its application

Microfabrication technology is a new processing technology invented by Swiss company BinC. It won two invention awards at the International Surface Treatment Exhibition (SITS) held in Paris, France in 2004 and the ALLIANCE exhibition held in Lyon, France in 2004. Micro-processing technology and equipment are protected by international patents.

Microfabrication technology combines two innovative technologies of ultra-fine brightening and ultra-fine polishing to selectively retain the microstructure of the surface to improve the friction and sliding properties of the surface (surface technology), replacing traditional manual with mechanization and automation. Polished to enhance the aesthetic function of the surface. This micromachining technology is applied to cutting tools, stamping and forging tools, surface treatment of mechanical parts such as aerospace, automotive, medical equipment, plastic injection molds, etc., which can greatly improve the surface performance of parts.

Principle of micromachining

The micro-machining technology uses a fully automatic method to super-finish the surface of metal parts, and removes 1 to 40 μm of material on the surface of metal parts by a mechanochemical action to achieve N1 grade with a surface roughness of finished or better than ISO standard. Surface Quality. Micro-machining technology is mainly used in the fields of super-fine polishing and super-fine brightness. Ultra-fine polishing automates the traditional manual polishing process, while ultra-fine polishing creates a new surface topology.

An outstanding advantage of microfabrication technology is the ability to impart a new microstructure to the surface of the part. These microstructures improve the adaptability of the part surface to specific application functions. Such as reducing friction and mechanical differences, improving wear resistance, improving the deposition properties of the surface before and after coating.

In general, ultra-fine brightness can remove the secondary micro-rough surface, and the thickness of the secondary rough surface is between 0 and 20 μm, which is located between the peaks of the primary micro-rough surface of the surface of the part. Ultra-fine polishing removes the primary micro-rough surface partially or entirely, with values ​​between 10 and 40 μm, depending of course on the initial state of the surface of the part material.

Micromachining technology has been able to process materials such as annealed and hardened steel, copper and copper alloys, cast iron, Inconel nickel alloy (nickel-based alloy), titanium metal, surface hard coating pretreatment (PVD, CVD, electroplating ).

Microfabrication is an innovative micromachining process that selectively refines the surface roughness and topology of the object being processed. This mechanochemical processing technology is a fully automated processing technology for automotive, electronics, chemical, metallurgical, mechanical, and aerospace manufacturing industries, especially injection molds, tool and machine tools, high precision parts, optics. And surface pretreatment before and after hard coating treatment.

Application of micromachining technology

Micro-machining technology can reduce the friction and improve the anti-wear performance by changing the fine structure of the material surface, and significantly improve the surface properties of the material. It has broad application prospects in the tool industry. If the ultra-fine brightening technology is adopted, the secondary micro-rough surface can be completely eliminated, the friction can be reduced, the chip removing performance of the tool can be improved, and the cutting force can be reduced; while the primary rough surface is maintained, the lubricating oil film is protected and the chip discharging performance of the tool is improved. , to reduce heat; if the pretreatment coating base is optimized before the coating treatment, or the coating is completely removed after the coating to cause a rough surface, the adhesion of the PVD coating can be improved, the service life of the tool can be extended, and the tool surface can be eliminated. The problem of built-up edge.

This innovative process has clearly demonstrated in recent years in many industrial applications that microfabrication technology can significantly reduce the cost of superfinishing; greatly shorten the production cycle; conveniently improve the quality of the surface, and use this processing Processed surfaces have unparalleled consistency and reproducibility.
