Description

Technical Field

[0001] The utility model relates to the field of grinding processing devices, in particular to a closing grinding device. Background Art

[0002] Edge grinding devices are devices used for precision grinding and finishing of workpieces, usually in metalworking, woodworking or other material processing fields. These devices can help grind, polish and finish the edges or surfaces of workpieces to achieve the desired accuracy and smoothness.

[0003] A general closed workpiece is a barrel-shaped object with one end open and the other end spherically sealed. During the operation of general automatic grinding equipment, the grinding device needs to exert a certain pressure on the grinding surface to ensure the grinding effect. However, due to its own structure, the open end of the closed workpiece is prone to deformation and shrinkage when squeezed by external force, resulting in errors in the workpiece size after grinding.
