What are the main factors that affect the quality of metal cutting?
Mechanical surface quality refers to the micro roughness of the machined surface after the machining, also known as roughness. The surface quality of the machined parts directly influences the physical, chemical and mechanical properties of the machined parts. The performance, reliability and life of the product depend to a great extent on the surface quality of the main parts.
Influence of wear resistance on surface quality. A just finished friction pair two contact surface, the initial stage in the surface roughness of the peaks of the contact, the actual contact area is far less than the theoretical contact area in contact with each other, the Department has a very large unit of stress, the actual contact area generated at the shear plastic deformation and elastic deformation between shape and peak damage caused by severe wear.
It is of great significance to correctly understand the connotation of the surface quality of the parts and to analyze the various technological factors affecting the surface quality in the process of mechanical processing, to improve the surface quality and to improve the performance of the products.
