How can the bearing steel ball diameter be the same size May 14, 2018

The internal stress of the steel ball of the bearing steel is mainly under the action of the external force during the operation, and effectively exists inside the material itself. To a certain extent, the balance stress of the material itself needs to be maintained. The internal stress is generally due to the deformation due to the external force during the processing of the steel ball, and generates internal forces in the metallurgical structure inside the steel to resist the external forces and try to make the object From the position after the deformation to the deformation, the roundness of the ball is not changed.

The internal stress of the bearing steel ball has its internal stress, so that it will be used for a long time, which will directly cause the surface of the steel ball to be easily broken, mainly because of the interaction between the internal stress of the steel ball and the external force. The surface tends to become brittle and the ball will break during grinding and polishing. Therefore, the stress in the steel ball must be released. There are many ways to eliminate the internal stress, you can heat treatment of the metal workpiece, you can also strengthen the treatment of the metal workpiece, or by tapping the internal stress elimination method.

How can the bearing steel ball diameter be the same size

Bearing steel ball to a certain extent, to control the diameter of the steel ball, to a certain extent, the first step is the need for cold heading step need to adjust and control the size, each cutting or because not every ball is subject to the same rotation and With the transfer of force, the ball will have various problems in the various steps of circulation. Surface scratches, inconsistent size, etc. Thus, the selection of steel balls is an important link.

The bearing steel ball can be selected after each operation in the process of operation. When it is used, it needs to filter out the unqualified ball size, so that it can effectively ensure the stainless steel to a certain extent. The diameter of the ball is uniform.

The diameter of the bearing steel ball is tightly controlled. To a certain extent, the ball sorting machine is indispensable. The steel ball sorting machine has an accuracy of 0.001 mm or less. The ball in the ball can be selected. It also ensures the quality of finished steel balls produced by precision steel ball mills.
