Description

Technical Field

[0001] The invention relates to the field of grinding wheel grinding equipment, in particular to a grinding wheel grinding auxiliary device. Background Art

[0002] When the grinding wheel is grinding, its abrasive grains are irregular polyhedrons with blunt edges. The grinding process is a complex process consisting of three actions: cutting, scoring (extrusion) and polishing. During the grinding process, some of the more prominent and sharp abrasive grains on the grinding wheel cut deeper into the workpiece, cutting a larger thickness and playing a cutting role; while the duller abrasive grains play a scoring role, squeezing into fine grooves on the surface of the workpiece; and the duller sand grains play a polishing role. After the cylindrical pipe is cut, the cut surfaces at both ends need to be polished. Generally, the staff holds the pipe to polish. Manual operation cannot guarantee the stability of the grinding angle and force, resulting in uneven grinding quality. Holding the pipe for a long time makes the pipe rotate slowly, which requires a high level of ability of the staff. In addition, long-term work consumes a lot of physical energy.
