Background

With the improvement of the requirements of various industries on the precision and the service life of conical and cylindrical roller bearings, the requirements on rolling elements, namely rollers, are higher and higher, wherein the processing of the end surfaces of the rollers is more and more important in each processing of the rollers. At present, in the processing of the ball base surface of a roller, a simple horizontal ball base surface grinding machine is mostly adopted, a working disc cannot be made to be large due to structural limitation, and meanwhile, eccentric vibration is easy to generate due to the fact that an axis is in the horizontal direction, and the rotating speed cannot be high. The diameter of the ball base surface depends on the diameter of the working disc, so that the ball base surface with large diameter cannot be processed; because the rotating speed cannot be increased, the processing efficiency of the ball base surface is low, and the processing quality cannot be improved. In addition, in most of the ball-based surface processing of the roller, grinding is used as a final step of the ball-based surface processing, and the processing quality (particularly, the appearance quality) cannot be further improved.

An effective solution to the problems in the related art has not been proposed yet.
