The diamond grinding wheel has strong abrasive grain, long life, and low abrasion, making the diamond grinding wheel give full play to its wear resistance and great grinding effect in high-speed, ultra-high-speed, high-efficiency and high-precision grinding. It becomes the first ideal tool for the grinding of brittle materials such as glass, ceramic, gems, stones and hard alloys. Feature: Effectively grind difficult-to-machine materials such as hard alloys, glass, and ceramics. High wear resistance makes diamond grinding wheel a tool that can satisfy both high efficiency and precision machining. Good cutting performance ensures the smaller grinding force, reducing the grinding power and energy consumption. Good thermal conductivity can avoid burns, cracks of the workpiece, greatly improving the processing quality. Ideal tool for the grinding of brittle materials such as glass, ceramic, gems, stones and hard alloys.
