Powered abrasive grinding, cutting, polishing, and wire buffing wheels create
special safety problems because they may throw off flying fragments. Before an abrasive wheel is mounted, it should be inspected closely and sound or ring-tested to be sure that it is free from cracks or defects. When conducting a sound test, tap the wheel gently with a light non-metallic instrument. A sound and undamaged wheel will give a clear metallic tone or "ring." If it sounds cracked or dead, the wheel could fly apart during use. Therefore, it must not be used. To prevent the wheel from cracking, the user should be sure it fits freely on the spindle. The spindle nut must be tightened enough to hold the wheel in place, without distorting the flange. Follow the manufacturer's recommendations. Care must be taken to assure that the spindle wheel will not exceed the abrasive wheel specifications. |
