Technológia mikro CNC obrábania využíva plne automatickú metódu na superfinišovanie povrchu kovových častí. Prostredníctvom určitého druhu mechanochemického pôsobenia, odstráni sa materiál 1-40μm na povrchu kovových častí, a kvalita povrchu opracovaného povrchu dosahuje alebo je lepšia ako úroveň N1 normy ISO. Technológia mikro CNC obrábania sa používa hlavne v dvoch oblastiach ultra presného leštenia a ultra presného zjasňovania. 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.
Všeobecne, super-precision brightening can remove secondary micro-rough surfaces. The thickness of the secondary rough surface is between 0 a 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 a 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), titán, Pretreatment (PVD, CVD, galvanické pokovovanie) before and after surface hard coating treatment.
