Description

Technical Field

[0001] The utility model relates to the technical field of steel ball processing, in particular to a transmission shaft steel ball grinding machine with a dust collecting function. Background Art

[0002] Steel balls are essential for the bearing and crushing industries. Common steel balls include bearing steel balls, stainless steel balls, carbon steel balls, and alloy balls. Although small, steel balls have a very important bearing capacity and lifespan in the transmission world, and their production process directly affects product quality.

[0003] Steel balls are usually formed by cold forging and stamping. The formed steel balls have burrs and rings, and need to be ground to make the surface smooth. Usually, the steel balls are repeatedly ground between two grinding discs, and diamond powder and grinding fluid are added to help the steel balls grind. However, steel ball grinding will produce a large amount of metal debris. The fine metal debris and diamond powder may float in the air with the vibration generated by the operation of the motor, and workers may inhale them into their lungs. Most of the metal debris is mixed with the grinding fluid, which is inconvenient to recover. For this reason, we propose a drive shaft steel ball grinder with dust collection function.
