[0003] Most of the existing resin grinding wheels do not have a good heat dissipation effect. Therefore, during the high-speed rotation of the resin grinding wheel cutting disc, it is easy for the body to heat up and produce high temperature, which can easily cause its structure to deform slightly and break, thereby causing the cutting quality of the resin grinding wheel cutting disc to decrease. In view of this, a resin grinding wheel with automatic coaxial function is proposed to solve the above problem. Utility Model Content

[0012] Both sheets of resin grinding wheels are provided with heat-conducting holes, and the metal reinforcing sheet is inlaid with a heating rod;

[0013] The overheating rod passes through the heat-conducting through hole and is welded and fixed to the metal heat-conducting rod.

[0021] Both ends of the fixed top rod are arc-shaped.

[0022] Compared with the prior art, the beneficial effects of the utility model are:
