A plurality of support columns 6 are evenly arranged between the heat-conducting support plate 5 and the alloy reinforcing rib plate 7 to ensure the connection stability between the heat-conducting support plate 5 and the alloy reinforcing rib plate 7. Part of the grinding heat generated during grinding flows to the outside through the heat-conducting groove 4, and part of the grinding heat is transferred through the heat-conducting support plate 5, and the open gap between the heat-conducting support plate 5 and the alloy reinforcing rib plate 7 is used to quickly dissipate heat.
