During the application process, if cracks are found locally on the grinding wheel, it should be immediately stopped and replaced with a new grinding wheel to prevent the formation of grinding wheel breakage and personal injury.

3、 Diamond grinding wheel expired and cannot be used anymore

The new grinding wheel received from the warehouse may not necessarily be a qualified grinding wheel, and even the new grinding wheel purchased from the manufacturer may not necessarily be a qualified grinding wheel. Any grinding wheel has a certain useful period, and when used within that period, it is a qualified grinding wheel; If used beyond its useful life, it is not necessarily a qualified grinding wheel. The regulation states that grinding wheels should be used within their useful life. After one year of storage, resin and rubber bonded grinding wheels need to undergo reverse testing, and only those who pass the test can be used.
