Reasons That Grinding Wheel Molds Are Not Durable

There will be wastage in the process of using grinding wheel. In fact, users have been aware that grinding wheel itself belongs to consumable items. What we care about is the speed and the degree of the grinding wheel wear. These problems are always difficult problems for users. Now, we can let professional and technical personnel solve the "puzzles" for users.

A, The material problem about the main parts of molds : improper material selection. The material performance is bad and not wear-resisting; Die steels have not been refined, with a large amount of metallurgical defects; Convex-concave die and forging stock forging process are imperfect, and there remains hidden dangers about heat treatment.

B, The structure design of molds : The mold structure is not reasonable. The thin punch does not have strengthening device design; The discharging mouth is not free; The strong discharging force makes the punch under aggravated cyclic loading.

C, The molding process is imperfect, which is mainly shown in the convex and concave die forging: The internal quality is poor, and there is a problem about heat treatment technology and process, which causes the convex and concave die with soft point and uneven hardness. Sometimes, it produces micro cracks; The grinding and polishing do not meet the designated requirements; The surface roughness value is too large.

D, It does not have lubrication effect or the lubrication effect is not that great.
