M8101A和M8102A两种型号的双端面磨床原是活塞环双端面磨削的专用机床。去年新昌轴承总厂第一次将这两种型号的机床用于轴承套圈加工,效率高,刚性好,加工平行差小,操作调整比较方便。在1989年11月召开的两种双端面磨床现场座谈会上,得到二十多个轴承厂和机床厂代表的好评,并纷纷要求订货。会后,乳山机床厂为了使该机更有利于轴承套圈的加工,进行了一些改进,将原来的活塞环送料机构改为适合
M8101A and M8102A two types of double-face grinding machine is the original double-sided piston ring grinding machine. Last year, Xinchang Bearing Factory for the first time these two models of machine tools for bearing rings processing, high efficiency, good rigidity, processing small difference in parallel, the operation is more convenient to adjust. In November 1989 held two kinds of double-face grinder on-site seminar, received more than 20 bearing plant and machine tool plant representatives praised, and have ordered the order. After the meeting, Rushan Machine Tool Plant in order to make the machine more conducive to the processing of bearing rings, made some improvements, the original piston ring feed mechanism to suit
