Why CNC precision machining requires electroplating

CNC parts processing often involves surface treatment processes, one of which is more common in electroplating. The so-called electroplating is the process of applying a thin layer of other metals or alloys using the principle of electrolysis on the surface of metals. The metal plating layer is coated on the substrate, and the intention of electroplating is to modify the surface properties or scale of the substrate.

Electroplating is generally divided into water plating and vacuum plating. Some CNC parts (such as rings) are small in size and cannot be fixed with a clamp. They need to be hung up and placed in a water plating solution for slight shaking, which can be completed in a short time (such as silver plating, only 30 seconds) This method is called water plating. Some CNC precision machining has a relatively large volume, which can be fixed on a fixture, sprayed with conductive paint, and then evacuated. This method is called vacuum plating.

The electroplating in CNC lathe processing, the coating metal is mostly corrosion-resistant metal, which can enhance the metal's corrosion resistance, add hardness, avoid wear, improve conductivity, lubricity, heat resistance, and beautiful surface. Although CNC machining in Shenzhen uses electroplating skills, there are still differences in electroplating because of different processing materials. If the metal material is directly electroplated, it will simply fall, so the metal electroplating needs to be sprayed with a layer of primer first, so that the electroplating effect will be very good, and the anti-corrosion time will be longer. The plastic has a strong adsorption force and can be directly electroplated on the surface.
