Surface quality of The mold processing affects three aspects of the service life of the parts.
die on three aspects of service life of parts: the influence of surface quality of
the corrosion resistance of 1 on parts. Whether it is chemical or electrochemical corrosion, the corrosion degree is related to the roughness of the surface. Corrosive medium is generally in the surface roughness concave Valley, especially in the surface crack in the strongest role. The corrosion process is usually carried out by the micro cracks in the hollow Valley to the inner layer of the metal layer. Effect of surface quality of
fatigue strength of parts. 2 on Under the action of alternating load, the surface roughness, scratches and cracks and other defects can cause stress concentration And fatigue crack, resulting in fatigue damage of parts. Effect of the surface quality of
3 on the coordination properties of parts cooperation relationship between the compound die of mating parts is used amount of interference or clearance to represent, in the gap, if the parts with rough surface and make the mating components soon wear and increase with the gap, with nature and reduce fitting accuracy. the surface quality of
