Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheels, in particular to a high heat dissipation grinding wheel. Background Art

[0002] Grinding wheel is also called bonded abrasive. Grinding wheel is a bonded abrasive that is bonded into a certain shape (mostly round with a through hole in the center) by a binder. It has a certain strength. Grinding wheel will generate a lot of heat during high-speed operation. After long-term use, the existing grinding wheel structure will inevitably produce certain mechanical fatigue, and the grinding wheel needs to be cooled.

[0003] The existing grinding wheel cooling method is to stop working after a certain period of use, and the grinding wheel will dissipate heat naturally. Some grinding wheels made of special materials can be directly sprayed with cold water for heat dissipation.

[0004] This method of naturally letting the grinding wheel stand still and spraying to cool it down has some problems. For example, static heat dissipation affects the work efficiency, and some grinding wheels cannot be directly sprayed with cold water to cool them down. For this reason, we propose a high heat dissipation grinding wheel. Utility Model Content
