Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, in particular to a tilting centerless grinder for processing bearings. Background Art

[0002] Tilt bearings are essential components used to support rotating mechanical shafts. To ensure optimal contact between the shaft and bearing, bearing machining requires precision and efficiency. Centerless grinders are specialized equipment commonly used for bearing machining, enabling high-precision and efficient machining.

The utility model provides a centerless grinder for processing precision bearings. Through the design and use of a series of structures, the utility model solves the problem that although the purpose of spraying water to cool the processed bearings and recycling water resources can be achieved during use, the driving power source of the grinding wheel and guide wheel, such as the drive motor, cannot be simultaneously dissipated and cooled during use, thereby extending the service life of the drive motor and thereby improving the practicality of the centerless grinder for processing precision bearings.
