Description
technical field [0001] The invention belongs to the technical field of steel ball sorting, and in particular relates to a high-precision sorting device and method for steel ball diameters. Background technique [0002] The consistency of the geometric size of the steel ball has a direct impact on the quality of the bearing. The better the ball size consistency, the better the bearing quality. At present, the steel balls produced by most domestic manufacturers have a diameter variation of 0.5 μm to 1 μm in the same batch, and a roundness error of 0.05 μm to 0.08 μm. Domestic steel ball sorting equipment adopts mechanical roller screening. Due to the processing and assembly precision, this sorting method cannot achieve high-precision screening. The highest sorting precision that can be achieved at present is 2 μm. In order to further improve the quality of the bearing, it is necessary to sort the steel balls into different groups according to the diameter, and the inner dia...
