Edge grinding whetstone with high heat dissipation performance

The utility model relates to the technical field of diamond grinding tools, in particular to a high-heat-dissipation edge grinding whetstone which comprises a fixing frame, supporting legs and a supporting frame, the supporting legs are arranged below the fixing frame, the supporting frame is arranged above the fixing frame, a cooling box is fixedly connected in the fixing frame, and the cooling box is fixedly connected with the supporting frame. When the lens grinding device works, air is sucked through an air suction pump to fix a lens on a suction head, a movable ball is adjusted through the suction head to adjust the lens to a proper angle, the lens is ground by sliding the fixing device, and a motor drives a grinding stone to grind during grinding. In the grinding process, water in the cooling box is conveyed into the grinding stone through the conveying pipe by the water pump and is discharged through the water discharging pipe in the grinding stone for cooling, heat generated in the grinding process ca
