What are the factors affecting the surface roughness of precision hardware parts? The surface roughness determines the quality of the parts. The higher the roughness, the better the quality of the parts. Objectively speaking, the following three factors affect the surface roughness of precision metal parts: Aspects:
First, the physical factors, in the cutting process of the workpiece, the fillet and the extrusion of the blade can deform the metal material, which will cause the surface roughness to be seriously deteriorated. In the processing of the plastic material, the chipping will form a chip due to the formation of a chip. Tumor, and hardness is very high. The appearance of the built-up edge is very irregular, so it is very easy for the surface of the workpiece to appear uneven knife marks. This will inevitably increase the surface roughness of the product
Second, the process factors, from the perspective of our precision metal parts processing technology, there are actually many factors that will affect the surface roughness, mainly the factors of the cutter, the workpiece material, the numerical control processing conditions and so on.
Third, geometric factors, mainly subject to the shape of the tool, declination, declination, etc. will be affected by the surface roughness
