The tip of properly use of abrasive wheels :
Do always handle and store wheels in a careful manner. Do visually inspect all wheels before mounting for possible damage. Do make sure operating speed of machine does not exceed speed marked on wheel, its blotter container. Do check mounting flanges for equal size, relieved as required & correct diameter. Do use mounting blotters as required by A.N.S.I. Standard. Do be sure work rest is properly adjusted on bench, pedestal and floor stand grinders. Do always use safety guard that covers a minimum of one-half (1/2) the abrasive wheel. Do allow newly mounted wheels to run at operating speed. Do always wear safety glasses or some type of approved eye protection while grinding or cutting. Do turn off coolant before stopping wheel to avoid creating an out-of-balance condition Do follow common sense safety considerations. Do follow federal, state and local laws and regulations.
Don't use a wheel that has been dropped or appears to have been abused. Don't force a wheel onto the machine or alter the size of the mounting hole. Don't ever exceed maximum operating speed established for the wheel. Don't use mounting flanges on which the bearing surfaces are not clean, flat and smooth. Don't tighten the mounting nut excessively. Don't grind on the side of conventional, straight or Type 1 wheels. Don't use a wheel on any machine that is not properly designed for the specific application of the wheel. Don't start the machine until the safety guard is properly and securely in place. Don't jam work into the wheel. Don't stand directly in front of a grinding/cutting wheel whenever a machine is in operation. Don't grind or cut material for which the wheel is not designed.
