Bearing ferrule , outer diameter rescue

On the ferrule , outer raceway rescue
bearing manufacturer ring grinding design basis for the inner or outer diameter , that is, first grinding inside ( outside ) diameter after grinding raceway, within circle , for example, if the inner raceway asymmetric type defects exist , you need to accurately measure the parts diameter size , and calculate the maximum amount of M and grinding inner raceway defect maximum grinding capacity M1. When M1 <M when the grinding required when the inner diameter of center shift , the maximum offset of M1 / 2, which give the processing of the inner raceway diameter of the defect in advance the amount of relative increase in grinding , internal grinding, and then raceway , its focus will be grinding defects , scrap was saved. When M1 ≥ M , the normal grinding mill can not afford .
Center offset method is used to ensure the parts grinding hardness, case depth under the premise of the total offset can not be completed in a single shift grinding , grinding generally divided into several times , that is, through the offset test grinding - measurement - adjust offset - try to complete the iterative process of grinding , to be worn defects , re- alignment, the normal Bearing test machine correction ovality . This method is less efficient , but requires the operator to have a higher level of technology , but in the stand-alone, single-piece production using this method to save a high success rate , not to delay the production schedule. After several years of proven good effect.

Bearing ferrule , outer diameter rescue
First, the presence of the defect part ( asymmetric type ) accurate measurement of the dimensions , where the calculated minimum grinding capacity ( to the finished size of the grinding capacity deviation ) M, and then grinding the parts center offset ( defect toward the direction of increasing offset grinding capacity ) , the maximum offset of M / 2, that the relative increase of the defect at the grinding capacity , focusing grinding .
