Problems solved by technology

[0003] At present, the domestic grinding wheel has not solved the problem of wear resistance well. The self-sharpening of the grinding wheel is poor, so it can only be used temporarily by reducing the hardness of the grinding wheel, but the reduction of the hardness of the grinding wheel will make the grinding wheel consume too quickly. Security risks
In addition, the contact area between the ordinary grinding wheel and the parts is large, the friction resistance is large, the temperature in the grinding area is high, and the parts are prone to thermal deformation due to excessive temperature.

Description

technical field [0001] The invention relates to the field of grinding wheel materials, in particular to a high-hardness and wear-resistant grinding wheel and a preparation method thereof. Background technique [0002] The grinding wheel is an important cutting tool mainly made of abrasives and applied on the grinding machine. Whether the selection of the grinding wheel is suitable or not directly affects the grinding performance and processing accuracy of the grinding machine. Therefore, the grinding wheel is an important factor for the performance of the grinding machine. When determining the specifications of the grinding wheel, the main factors to be considered are: the material and hardness of the workpiece, the grinding amount and precision requirements, the grinding method, the speed of the grinding wheel, the grinding contact area and the intensity of the grinding method, etc. There are many types of grinding wheels, and there are various shapes and sizes. Due to the ...
