我厂有一台东德进口的轧辊磨床,可磨最大直径为1m,长度为6m,用于磨削四辊冷轧机和平整机用的轧辊。自1971年投产以来,只进行过一些检查及排除故障性的小修。1981年,机床运转开始不正常,精磨出的轧辊出现了可见的纵向波纹,光洁度下降至▽V8,严重影响了冷轧耐热板和不锈钢板的表面质量。 经检查发现: 1)砂轮轴和轴承间隙约0.03mm; 2)床身导轨A、B、C三项精度均超差,
Our factory has an East Germany imported roller grinder, grinding maximum diameter of 1m, length of 6m, for grinding four-roll cold rolling mill and leveling machine roll. Since its commissioning in 1971, only a few minor repairs have been conducted to check and troubleshoot. In 1981, the operation of the machine tool began to be abnormal, the visible longitudinal corrugation appeared on the finished roller, the finish decreased to ▽ V8, seriously affecting the surface quality of the cold-rolled heat-resistant plate and the stainless steel plate. The inspection found that: 1) grinding wheel shaft and bearing clearance of about 0.03mm; 2) bed rail A, B, C are three ultra-precision,
