Bearing grinding method

Abstract

The invention discloses a bearing grinding method and belongs to the field of metallurgical machinery maintenance. According to the bearing grinding method, when a grinding machine is assembled, one side, without the opening, of a bearing is made to be downward, so that cutting fluid is prevented from entering the bearing in the grinding process; coarse grinding is conducted on 10 micrometers of the bearing, and then accurate grinding is conducted. The bearing grinding method can improve the grinding accuracy of the bearing, ensure the assembly accuracy of the bearing, achieve stability of a rolling mill roll system, effectively avoid the off-tracking phenomenon of strip steel, improve the rolling efficiency of the strip steel, and improve the product quality of the strip steel.

Description

technical field [0001] The invention belongs to the field of metallurgical machinery maintenance, and in particular relates to a bearing grinding method. Background technique [0002] During the rolling process of the 20-high rolling mill, when the rolling speed reaches 200m / min, the deviation of the strip often occurs, resulting in poor shape of the strip. Contents of the invention [0003] In order to improve the bearing grinding precision, ensure the bearing assembly precision, and realize the stability of the rolling mill roll system, the invention provides a bearing grinding method. [0004] Technical scheme of the present invention is: [0005] 1. When assembling with the grinding machine, put the side of the bearing without opening downwards to prevent cutting fluid from entering the bearing during the grinding process; [0006] 2. Coarse grinding 10um enters the fine grinding process. [0007] The invention can improve the grinding precision of the bearing, ens...
