往复活塞式压缩机环状阀片是薄片零件,刚性差,易变形,两端面粗糙度要求高,而且成品要求不带磁性。因此,在普通平面磨床上采用电磁吸盘装夹进行磨削的方法不能达到质量要求。我们采用的磨削方法是:如图所示,以阀片内孔和端面定位,湿绒布吸紧工件与转盘一起旋转,磨削一端面,再将工件翻面,磨削另一端面,如此反复若干次,就能达到图纸要求。 Reciprocating piston compressor ring valve is a thin sheet parts, poor rigidity, easy to deform, demanding both ends of the roughness, and the finished product requirements without magnetic. Therefore, the ordinary surface grinder on the use of electromagnetic chuck clamping method of grinding can not meet the quality requirements. We use the grinding method is: As shown in the valve hole and the end surface positioning, wet velvet suction workpiece with turntable rotation, grinding one end, then the workpiece turned over, grinding the other end, and so on Repeated several times, will be able to meet the drawings requirements.
