In the process of machining the steel ball, special equipment is needed to grind and polish the steel ball so as to achieve the best using effect of the steel ball. The steel balls with larger specifications are generally ground and polished by using a grinding wheel, the steel balls with smaller specifications are generally ground and polished by using a whipped barrel, the so-called whipped barrel is a cylindrical grinding box with a grinding layer arranged in an inner cavity, and when the grinding box rotates, the steel balls roll on the inner wall of the grinding box and rub against the inner wall to achieve the grinding effect. However, the inner wall of the common polishing box is a simple arc surface, the polishing area is small, and the polishing efficiency is low.
Because the steps of selecting inferior-quality products are not carried out in the separation and polishing processes of the steel balls, the steel balls polished out can have the inferior-quality products with the defects of sand inclusion, slag inclusion, holes, mold dislocation and the like, and how to select the inferior-quality products is also a technical problem which needs to be considered by technical personnel.
