Factors affecting the surface roughness of precision metal parts

  What are the factors affecting the surface roughness of precision metal parts? The surface roughness determines the quality of the parts. The better the roughness, the higher the quality of the parts. Objectively speaking, the factors affecting the surface roughness of precision metal parts are mainly the following three. Aspects:

  1 Physical factors, during the cutting process of the workpiece, the corners and extrusion of the cutting edge can deform the metal material, which will seriously deteriorate the surface roughness. In the processing of plastic materials, the built-up edge will also form due to the formation of ribbon cutting, and The hardness is very high. The appearance of the built-up edge is very irregular, so it is very easy to make the surface of the workpiece appear in different depths and widths. This will inevitably increase the surface roughness of the product.

  2 Process factors, in terms of our precision metal parts processing technology, there are actually many factors that will affect its surface roughness, mainly in terms of tools, workpiece materials, CNC machining conditions and other factors.

  3 Geometric factors, mainly subject to the shape of the tool, declination, secondary declination, etc. will be greatly affected by the surface roughness.
