Care should be taken to prop-erly adjust machine parts so that there is not sufficient space be-tween them and the wheel to allow the work to become work rest should be adjusted as closely as possible to thegrinding wheel, as breakage may be caused from somethingdropping between the rest and the wheel. Instances are known where breakage was the result of the. Wheel Broken from Excessive Heat Get. I Led in Grinding grinding surface of the wheel becoming very much the direct cause for such breakages is the fact that thewheel becomes glazed so that excessive pressure is necessary tokeep up production. The remedy is to keep the wheel sharp orobtain a wheel better suited for the operation in question. Serious accidents have happened where large castings areground while suspended by means of a chain hoist and throughcarelessness the castings are allowed to strike against the wheel. A cause of wheels running out of true is directly traceable tolack of proper attention to the machine bearings. The bearingsbecome highly heated, the bearing metal flows, a heavy brakeaction is produced on the spindle and when the machine isstopped the momentum of the grinding wheel is sufficient to loosenthe mounting. When the wheel is started again, the nut will notautomatically tighten and the wheel will be running under dan-gerous conditions. Wheels
