Under normal circumstances, the damage of mechanical equipment parts starts from the surface of the parts.
Under normal circumstances, the damage of mechanical equipment parts starts from the surface of the parts. The performance of a product, especially the stability and durability of the product, depends to a large extent on the processing technology and processing quality of the surface of the parts. Processing Parts Factory Zhuhai Baiwei Machinery Analysis Factors Affecting Parts Surface Quality
1, cutting affects the surface roughness, in the mechanical cutting process, will leave the residual traces of the cutting layer on the surface, its shape and the geometry of the tool, we can reduce the feed of the tool, the main angle and the auxiliary angle or increase the radius of the tip of the arc to reduce the height of the residual traces. We can also increase the tool rake angle to prevent the degree of plastic deformation during cutting, to achieve the purpose of reducing surface roughness.
2. The nature of the workpiece material will affect the surface quality of the machined parts. When processing plastic materials, the extrusion of the metal by the tool will cause plastic deformation, and the tool will force the workpiece to be separated from the cutting. Tearing effect, resulting in an increase in the roughness value of its surface. If the toughness of the processed material is better, the plastic deformation of the metal will be greater, and the surface of the processed part will be rougher. For the processing of high toughness materials, higher cutting speed can be adopted to improve the surface finish.
