What are the factors affecting the surface roughness of precision hardware parts, surface roughness determines the quality of the parts, the better the roughness of the parts, the higher the quality, objectively speaking, the factors affecting the surface roughness of precision hardware parts are mainly the following three aspects.
First, physical factors, in the cutting process of the workpiece, the cutting edge rounding and extrusion can make the metal material deformation, which will make the surface roughness seriously deteriorate, in the processing of plastic materials will also be formed because of the formation of ribbon cutting and the formation of chip tumor, and very high hardness. The appearance of chipformers is very irregular, so they can easily cause tool marks of varying depths and widths on the surface of the workpiece. This inevitably increases the surface roughness of the product.
Second, the process factors, from our precision hardware parts machining process, in fact, there are many factors will have an impact on its surface roughness, mainly tool, workpiece material, CNC machining conditions and other aspects of the factors.
Third, geometric factors, mainly subject to the shape of the tool, declination, sub-declination, etc. will be surface roughness has a greater impact.
