Any grinding wheel has its certain wear requirements. When the wear reaches a certain level, a new grinding wheel must be replaced. Using it to save material is an extremely unsafe violation. When the grinding wheel is worn to a diameter 10mm larger than that of the chuck, a new grinding wheel should be replaced.
validity issue
The new grinding wheel taken out of the warehouse is not necessarily a qualified grinding wheel, and even the new grinding wheel purchased from the manufacturer is not necessarily a qualified grinding wheel. Any grinding wheel has a certain shelf life and can be used within the shelf life;
If it is used beyond the expiration date, it is not necessarily a qualified grinding wheel. According to relevant regulations, "grinding wheels should be used within the validity period. Resin and rubber bonded grinding wheels must be re-tested after being stored for one year, and can only be used after passing the test."
Texture problems During use, if cracks are found on the grinding wheel, stop using it immediately and replace it with a new one to avoid accidents caused by damage to the grinding wheel.
