Superfinitura di micropezzi di tornitura e fresatura

La tecnologia di lavorazione micro CNC adotta un metodo completamente automatico per la superfinitura della superficie delle parti metalliche. Attraverso una sorta di azione meccanochimica, viene rimosso il materiale di 1-40μm sulla superficie delle parti metalliche, e la qualità superficiale della superficie lavorata raggiunge o è migliore del livello N1 dello standard ISO. La tecnologia di lavorazione Micro CNC viene utilizzata principalmente nei due campi della lucidatura ultraprecisa e della brillantatura ultraprecisa. 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.

In general, 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), titanio, Pretreatment (PVD, CVD, galvanica) before and after surface hard coating treatment.
