Abstract
The invention discloses a steel ball production machining method. The method comprises the steps of selecting a proper finished product wire raw material, sequentially carrying out wire straightening, shearing, passivating, annealing, quenching, first-time tempering, grinding, second-time tempering and cleaning, and obtaining steel ball finished products. A shorn cylindrical blank is subject to passivating treatment through a tumbling mill, defects of flanges and the like generated after shearing are overcome, the under-punching defect appearing in the subsequent cold upsetting process is overcome, and in addition, compared with an existing heat treatment technology, the method has the beneficial effects that the hardness and the strength of the steel balls are obviously improved, and the quality requirement of the steel balls is met.
