Super acabamento de micro peças de torneamento e fresamento

A tecnologia de usinagem micro CNC adota um método totalmente automático para superacabamento da superfície das peças metálicas. Através de uma espécie de ação mecanoquímica, o material de 1-40μm na superfície das peças metálicas é removido, e a qualidade da superfície processada atinge ou é melhor que o nível N1 do padrão ISO. A tecnologia de usinagem micro CNC é usada principalmente nos dois campos de polimento de ultraprecisão e abrilhantamento de ultraprecisão. Ultra-precision polishing automates the traditional manual polishing process; The super-precision brightening generates a new surface topology.

An outstanding advantage of micro-CNC machining technology is that it can give new microstructures to the surface of the part. 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 coating.

Em geral, super-precision brightening can remove secondary micro-rough surfaces. The thickness of the secondary rough surface is between 0 e 20 μm, located between the peaks of the primary micro rough surface of the part surface. The super-finishing polishing removes the primary microscopic rough surface partially or entirely, and its value is between 10 e 40 μm. Of course this depends on the initial state of the part material surface.

The materials that can be processed by microfabrication technology so far are: Annealed and hardened steel, Copper and copper alloys, cast iron, Inconel nickel alloy (nickel-based alloy), titânio, Pretreatment (PVD, CVD, galvanoplastia) before and after surface hard coating treatment.
