Factors Affecting Surface Roughness of Cnc Metal Processing Precision Parts

Back to list 发布日期:18年06 月11日 Source: Jindong Metal Products Release Date: June 11, 2018

What are the factors that affect the surface roughness of cnc hardware processing precision parts? The surface roughness determines the quality of the part. The better the roughness, the higher the quality of the part. Objectively speaking, the main factors affecting the surface roughness of precision hardware parts are The following three aspects:

First, physical factors. During the cutting process of the workpiece, the fillet and extrusion of the blade can deform the metal material, which will seriously deteriorate the surface roughness. When machining plastic materials, it will also form chip deposits due to the formation of band cutting. Nodules and very high hardness. The appearance and performance of the built-up edge are very irregular, so it is very easy for the surface of the workpiece to have different widths, widths, and widths. This will inevitably increase the surface roughness of the product.

Second, the process factors, in terms of our precision metal parts processing technology, in fact, there are many factors that will affect its surface roughness, mainly including cutters, workpiece materials, CNC machining conditions and other factors.

Third, the geometric factors are mainly affected by the shape, declination, and declination of the tool, which will be greatly affected by the surface roughness.
