Microfabrication Technology and Its Application

Microfabrication technology is a new type of processing technology invented by Switzerland's BinC company. It won two invention awards at the International Surface Finishing Exhibition (SITS) 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.

The microfabrication technology combines the two innovative technologies of ultra-fine brightening and super-finish polishing to selectively retain the microstructure of the surface to improve the friction and sliding properties of the surface (surface technology), replacing the traditional manual with mechanization and automation Polished to enhance the aesthetics of the surface. This micro-machining technology is applied to the surface treatment of cutting tools, punching and forging tools, and aviation, automotive, medical equipment, plastic injection molds and other mechanical parts, which can greatly improve the surface performance of the parts.

Microfabrication principle

The micro-fabrication 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 through a mechanochemical action to achieve a N1 class surface roughness that is equal to or better than the ISO standard. Surface Quality. Microfabrication technology is mainly used in the two fields of superfinishing polishing and superfine brightening. Ultra-fine polishing automates the traditional manual polishing process, while ultra-fine brightening creates a new surface topology.

One of the outstanding advantages of microfabrication technology is the ability to give the part surface a new microstructure. These microstructures can improve the adaptability of part surfaces to specific application functions. Such as reducing friction and mechanical differences, improve wear resistance, improve surface deposition performance before and after coating.

In general, ultra-fine brightening removes the secondary micro-rough surface. The thickness of the secondary rough surface is between 0 and 20 μm, and it is located between the peaks of the primary micro-rough surface of the part surface. Superfinishing, on the other hand, partially or entirely removes the primary micro-roughened surface, and its value is between 10 and 40 μm, depending of course on the initial state of the surface of the part material.

The microfabrication technology has so far been able to process materials such as annealing and quenching of steel, copper and copper alloys, cast iron, Inconel nickel alloys (nickel base alloys), titanium metals, and surface hard coatings before and after pretreatment (PVD, CVD, electroplating).

Microfabrication technology is an innovative micromachining process that selectively refines the surface micro-roughness and topology of the object being processed. This mechanochemical processing technology is a fully automated processing technology and is applicable to industries such as automobile manufacturing, electronics, chemical engineering, metallurgy, machinery manufacturing, aerospace manufacturing, etc., especially injection molds, tools and machine tools, high-precision parts, and optical devices. , And before and after hard coating treatment surface pretreatment.

Micromachining Technology Application

The microfabrication technology can reduce the friction, improve the wear resistance, and significantly improve the surface properties of the material by changing the fine structure of the material surface, and has a broad application prospect in the tool industry. Such as using ultra-fine brightening technology, completely eliminate the secondary micro-rough surface, reduce friction, can improve tool chip removal performance, reduce cutting force; while maintaining the primary rough surface, is conducive to the protection of the lubricating film, improve tool chip removal performance , Reduce heat generation; if the pretreatment coating base surface is optimized before the coating treatment, or after the coating is completely removed to cause a rough surface, the adhesion performance of the PVD coating can be improved, the service life of the tool can be prolonged, and the tool surface can be eliminated. Problems with BUE.

The practical application of this innovative processing technology in many industrial fields in recent years clearly shows that micro-fabrication technology can significantly reduce the cost of ultra-finishing; greatly shorten the production cycle; easily improve the quality of the surface, and use this processing Processed surfaces have unmatched consistency and reproducibility.
