Factors affecting surface roughness of precision metal parts

- Aug 01, 2017 -

First, physical factors, in the workpiece cutting process, the blade fillet and extrusion can make the metal deformation, which will make the surface roughness seriously deteriorated, in the processing of plastic materials will also be formed by the formation of banded cutting and the formation of a very high hardness. The appearance of the chip is very irregular, so it is very easy to make the surface of the workpiece with different depth and width of the knife, this will inevitably increase the surface roughness of the product.

Second, the process factors, from our precision metal parts processing technology, in fact, there are many factors will affect its surface roughness, the main tools, workpiece materials, CNC processing conditions and other factors.

Third, the geometrical factors, mainly affected by the shape of the tool, deflection angle, and the deflection angle of the surface will be greatly influenced by roughness.
