Description

Workpiece grinding and positioning device

Technical Field

The utility model relates to the technical field of workpiece processing equipment, in particular to a workpiece grinding and positioning device.

Background Art

As we all know, in the process of machining, in order to remove burrs on the inner surface of the workpiece and make it smooth, it is easy to continue processing or reach the finished product, the workpiece needs to be polished. Grinding equipment is needed in the grinding process. Grinding equipment is widely used for the finishing and surface polishing of workpieces before proceeding to the next step.

When processing a disc workpiece, a fixing device is usually used to fix the disc workpiece, and then the staff manually grinds the periphery of the disc workpiece with a handheld grinder. However, in actual use, the staff only grinds the disc workpiece based on their work experience. During the grinding process, uneven grinding is likely to occur around the disc workpiece, affecting product quality.
