Its geometric parameters and physical properties directly affect the performance, level, quality and reliability of the bearing. The strengthening processing of bearing steel balls is usually carried out by a grinder. It mainly involves adding bearing steel balls and grinding materials to the drum of the grinder, and then driving the drum to rotate, so that the bearing steel balls produce centrifugal phenomena in the high-speed rotating drum, causing the bearing steel balls to collide with each other, which plays a role in surface strengthening.
