What are the post-processing methods of CNC machining?

101 Published by admin Mar 13,2020

CNC machining method of workpiece surface, the first depends on the technical requirements of machining surface.However, it should be noted that these technical requirements are not necessarily the requirements specified in the part drawing, and sometimes they may be higher than the requirements in the part drawing due to technological reasons.

CNC machining

CNC machining hardware surface processing subdivision can be divided into: metal oxidation processing, metal paint processing, electroplating, surface polishing processing, metal corrosion processing and so on

1.oxidation processing: the hardware factory in the production of finished metal products (mainly aluminum) to its use of oxidation processing, hardware products surface hardened, let it not easy to receive wear. 

2.spray paint processing: hardware factory in the production of large pieces of hardware finished products are used to spray paint processing, through the spray paint processing hardware to avoid rust, such as: daily supplies, electrical shell, handicrafts

CNC machining

3. electroplating: electroplating is also the most common CNC processing hardware processing technology, through modern technology on the surface of hardware electroplating, to ensure that products used for a long time without mildew embroidery, electroplating processing common: screws, stamping parts, batteries, car parts, small ornaments, etc.

4.surface polishing machining: surface polishing processing generally longer used in daily necessities, burrs treatment on the surface of a CNC machining metal products such as: we produce a comb, comb is by stamping parts, stamping out comb edge is very sharp, we have to part by polishing the edges sharp thrown into the smooth face, so that in the process of use does not cause harm to human body.
