Chrome steel ball grinding is the process of micro-cutting and destroying the surface of Chrome steel balls with abrasives. There are two types of micro-cutting, which are sliding cutting and rolling cutting. Among them, sliding cutting refers to the process of overlapping and staggering the numerous linear cuts formed by the extrusion and scraping of the surface of the Chrome steel ball under the action of abrasive grain cleavage; rolling cutting refers to grinding due to irregular shapes. The process of rolling and rotating the granules on the surface of the Chrome steel ball to form an egg skin-shaped point-like indentation process. During the Chrome steel ball grinding process, abrasives are continuously added to the grinding disc. The chemical action of the active substance will cause the oxide film on the surface of the Chrome steel ball to fall off quickly.
