平面磨床加工薄片工件难度较大。因为,一、工件薄,钢性差,磁吸盘易吸牢,造成跑活和工件重叠,挤碎砂轮;二、砂轮作横向进给时,由于工件本身不平使工件在砂轮下转动;三、砂轮与工件的瞬间接触,产生极大的磨削热(其温度约在500°～750℃左右),随着冷却液的大量供应,使坯料发生局部变形(即工件翘曲变形);四、不平度难控制,往往达不到图纸要求;五、由于工件薄,在磁力作用下容易产生变形,磁力消除后,工件恢复
Surface grinder processing sheet workpiece more difficult. Because, one, the workpiece is thin, steel is poor, magnetic sucker easy to absorb a prison, resulting in running and work overlap, crushing grinding wheel; Second, the grinding wheel for horizontal feed, due to uneven workpiece itself so that the workpiece turns under the wheel; With the instantaneous contact with the workpiece, resulting in a great grinding heat (its temperature is about 500 ° ~ 750 ℃ or so), with the large supply of coolant, the billet local deformation (that is, the workpiece warpage); Fourth, uneven Difficult to control, often fail to meet the requirements of the drawings; Fifth, due to thin workpieces, easy to produce deformation under the action of magnetic force, the magnetic elimination, the workpiece recovery
