5-3 Sound test Before Grinding wheel mounted in Grinding wheel head, place it on center shaft, strike it with a wood hammer, the sound shall be clear. Never use the Grinding wheel that is not usable based on such test. 5-4 Mounting Grinding wheel Mount Grinding wheel shall require experienced operators who shall softly push it into the fastener. Do not force it in. Grinding wheel side and between with the fastener shall be added elastic ring. Do not use paper for fixing the sides of Grinding wheel for wet grinding otherwise, when it gets dry, it will cause Grinding wheel loose; retaining nut should be tightened up to ensure Grinding wheel is secured firmly but excessive tightening is not recommended. Check tightness often is highly recommended. 5-5 Grinding wheel balance Calibrate When obtain perfect grinding finish is desired, carefully Calibrate Grinding wheel is essential. When Calibrate, one can use balancer or balance scale or electronic power balancer. Delivered with M/C, Grinding wheel and its fastener all have been conducted dynamic and static balance. However, check often is required due to Grinding wheel wearing. New Grinding wheel normally is balanced, and can be used right after sound test. Calibrate its balance is recommended after a period of use. When grinding to use Grinding/cutting liquid, idle run for 15 minutes is necessary for Grinding wheel to cause Grinding wheel orifices moisture escape to avoid bias. 5-6 Test run Before use of any Grinding wheel, test run at maxi. Allowable speed for 5 minutes is required and nobody shall stand near it. Only Grinding wheel that pass the test can be used. Please observe the max. allowable speed, do not exceed it. 51

5-7 Dressing Grinding wheel shall often be maintained in circular manner, and irregular Grinding wheel can be maintained in circular manner through appropriate Dresser Dressing. 5-8 Dry grinding Dry grinding operator shall wear protective glasses and dust shall be removed if worked for long. 52
