1. High hardness, sharp edges, and corners, good cutting performance, machining accuracy, and low grinding heat. It is a good tool for grinding. 2. The grinding wheel has high accuracy, high efficiency, and good roughness, resulting in less abrasive consumption and long service life. 3. Corundum has small particle size, impact resistance, and uniform particles. 4. Suitable for grinding hard and heat-sensitive steel, such as hardened steel, high carbon steel, alloy steel, and so on. Widely used for grinding and forming cutting tools, gears, threads, thin-walled parts, etc. 5. Please select the appropriate grinding wheel for appearance and sound inspection before installation. 6. Newly installed or used wheels every other day should be idling for more than one minute before use. 7. Do not stand in front of the wheel. The grinding wheel is fragile and should not be impacted or dropped; the storage should be dry and flat, and should not be stressed.
