MS74100A磨床是发动机厂三泵车间磨小连杆两个端面的设备,是小连杆生产线的第一道工序。加工时锻造毛坯面定位,电磁工作台将工件吸住。一、设备存在的问题该设备存在的问题是电磁工作台磁力不够,磨削时吸不住工件。按工艺要求,两磨头的一次加工分别为0.30mm (粗磨)和0.20mm (精磨)。机床出厂的设计标准是在磨削量为0.25mm时吸牢工件。但是据操作工人反映,在加工余量为0.04～0.05mm时就有工件
MS74100A grinding machine is the engine plant three pump mill small connecting rod both ends of the equipment, is the first rod production line process. Forging rough surface processing positioning, the electromagnetic table will suck the workpiece. First, the equipment problems The problem with the equipment is the electromagnetic table magnetic enough, unable to absorb the workpiece grinding. According to process requirements, two grinding head of a process were 0.30mm (coarse grinding) and 0.20mm (fine grinding). The design standard of the machine tool factory is to absorb the workpiece when the grinding amount is 0.25mm. However, according to the operation of workers reflected in the machining allowance of 0.04 ~ 0.05mm when there is a workpiece
