In the mechanical parts processing industry, many parts choose different surface treatment methods according to different processing technology. Does the surface treatment process affect the accuracy of parts? Let’s see
In the process of mechanical parts processing, the common surface treatment processes of metal materials are: Aluminum natural color oxidation, black oxidation, sandblasting, nickel plating, hard white, bluing and other different coloring. The general steel surface treatment processes are: blackening, chromium plating, zinc plating (black zinc), etc. according to the different surface processing processes of drawings, different treatment processes are selected. When the precision of precision parts is high and the surface treatment process affects the precision, the appropriate processing quantity of parts should be reserved first.
General steel surface treatment process chromium plating, zinc plating and blackening will not affect the overall dimensions of the parts. In case of aluminum blackening and oxidation, it will have more or less impact on the required precision holes. There is a special way to control the hole size accuracy during the treatment. Therefore, the surface treatment process has a certain impact on the accuracy of parts, which can be controlled in the process of processing or treatment.
The above is whether the surface treatment process has an impact on the accuracy of parts, thank you for sharing!
