Why does CNC precision machining need electroplating?
by：QY Precision 2020-02-20
CNC parts processing often involves surface treatment technology, one of which is more common in electroplating.
The so-called electroplating is the process of applying electrolysis principle to the metal surface and plating a thin layer of other metals or alloys.
Plating metal coatings on the substrate is intended to change the surface properties or dimensions of the substrate.
In the CNC lathe machining process, what is the effect of electroplating as a surface treatment skill? Now please come with Xiaobian to find out. Electroplating is generally divided into water plating and vacuum plating.
The specific method adopted by Shenzhen CNC machining manufacturers should be based on the characteristics of non-standard mechanical parts processing. Some CNC parts processing (Such as Ring)
It is small in size and cannot be fixed with a fixture. It needs to be hung up and placed in a water plating solution for slight shaking in a short period of time (Such as silver plating, only 30 seconds)Can be done, this way is called water plating.
Some CNC precision machining volumes are relatively large, can be fixed on the fixture, sprayed with conductive paint, and then vacuum, this method is called vacuum plating.
Electroplating in CNC lathe processing, coating metal is selected with corrosion-resistant metal, which can enhance metal corrosion resistance, add hardness, avoid wear, improve conductivity, lubricity, heat resistance, and beautiful surface.
Although Shenzhen CNC machining uses electroplating skills, there are still differences in electroplating due to different processing materials.
If the metal material is directly plated, it will simply fall, so the metal plating needs to be sprayed with a layer of primer, so that the electroplating effect will be very good, and the anti-corrosion time will be longer.
However, the adsorption force of plastic is relatively strong and can be directly electroplated on the surface.
