Problems solved by technology

[0002] As a commonly used abrasive tool, the grinding wheel is in a high-speed rotating state and needs to withstand a large impact force. Therefore, there are high requirements for the strength, impact resistance, heat resistance and corrosion resistance of the grinding wheel; the grinding wheel It is mainly made of abrasives and binders after compaction, drying, and roasting. In practical applications, it should be based on the use conditions of the grinding wheel workpiece. The existing grinding wheels cannot effectively balance the wear resistance, self-sharpening, cost, and grinding accuracy.
