Description

Technical Field

[0001] The invention relates to the field of grinding wheels, and more particularly to a high-efficiency grinding wheel for cutting castings and a cutting device thereof. Background Art

[0002] Grinding wheels are abrasive tools used in the grinding process. They are mainly made of ordinary abrasives bonded by a binder and can be used for grinding and cutting.

[0003] During the cutting process, the surface of the existing resin-bonded grinding wheel will produce severe friction with the cutting object, resulting in high temperature on the grinding wheel surface. Since the resin is not resistant to high temperatures, the binder will burn under continuous high temperatures, thereby causing damage to the resin-bonded grinding wheel. At this time, during the continuous high-temperature cutting process, the grinding wheel needs to be protected by sprinkling water to cool it down. Traditional sprinkling water to cool it down is mainly operated manually, which is relatively inconvenient to operate. In view of this, we propose an efficient casting cutting grinding wheel and its cutting equipment. Summary of the invention
