Introduction
630-Stainless steel bar are round or polygonal long stick-shaped workpieces with a certain length, which need to be polished during the production of the bar material. The stainless steel rod is placed in the gap between the two rollers and comes into contact with the two rollers at the same time, so that the motor drives the rotating shaft and the driving wheel to rotate. The driving wheel drives the driven wheel and the roller to rotate synchronously through the conveyor belt. The grinding machine moves, because the stainless steel rod and the roller want to contact, during the moving process, the roller rough grinds it, and then enters the grinder for fine grinding. After the processing, the stainless steel rod is sent out by the feeding device on the right.
