How is the bearing steel ball processed

- Jun 14, 2019-

The simple production process of bearing steel ball includes ball blank forming, de-ringing, rough grinding, soft grinding, heat treatment, ball forming, light ball, hard grinding, fine grinding, fine grinding and super fine grinding. The wire is stretched to the required wire diameter by a wire drawing machine; the drawn wire is placed in a steel ball cold heading machine, and the steel mold is beaten into a ball embryo; the two cast iron grinding balls in the light ball machine are rounded. The plate pressurizes the cold blast embryo to remove the outer band and the two poles on the globule.


Two cast iron grinding balls in the soft ball machine honing the ball of the photosphere to make the ball embryos into the required ball diameter and surface roughness; loading the ball into the heat treatment furnace for carburizing, quenching and tempering the ball It has a certain carburizing layer and hardness, toughness and crushing load; the grinding wheel circular plate in the grinding machine pressurizes the heat-treated ball embryo to remove the black oxide layer on the surface of the ball and correct the accuracy of the ball.


Grinding the ball embryo in the lapping machine to achieve the precision and smoothness required for the finished product; polishing cleaning: pour the ball into the polishing drum and rotate it with a polishing detergent to clean the surface; use manual visual inspection Whether there is any flaw on the surface of the steel ball, and the roundness is measured by a micrometer, the variation of the batch diameter and the surface roughness measured by the surface roughness meter are used as the final inspection. The surface of the bearing steel ball that meets the requirements is coated with anti-rust oil and then packed in a carton or woven bag. After the customer has requirements, it must be packaged and shipped according to customer
