Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, in particular to a production device for a precision bearing ring or a bearing. Background Art

[0002] A bearing is a mechanical element used to support rotating or linear motion, reduce friction and improve motion efficiency. Bearing rings are an important part of bearings and are usually divided into inner and outer rings. Their main function is to provide a smooth surface so that rolling elements (such as balls or rollers) can move freely on them, thereby reducing friction and supporting rotation or linear motion. When the bearing ring in the bearing is processed, the inner and outer sides of the bearing ring need to be turned. In the traditional bearing ring turning process, the bearing ring is first fixed on the positioning mechanism and rotated at high speed, and then the outer side of the bearing ring is turned using a turning tool head.
