Super efterbehandling af drejning og fræsning af mikrodele

Mikro-CNC-bearbejdningsteknologien anvender en fuldautomatisk metode til superfinishing af overfladen af ​​metaldele. Gennem en slags mekanokemisk handling, materialet på 1-40μm på overfladen af ​​metaldelene fjernes, og overfladekvaliteten af ​​den behandlede overflade når eller er bedre end N1-niveauet i ISO-standarden. Mikro-CNC-bearbejdningsteknologi bruges hovedsageligt inden for de to områder af ultra-præcisionspolering og ultra-præcisionsblanking. 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.

Generelt, super-precision brightening can remove secondary micro-rough surfaces. The thickness of the secondary rough surface is between 0 og 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 og 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), titanium, Pretreatment (PVD, CVD, galvanisering) before and after surface hard coating treatment.
