上海明精机床厂在过去一直生产中小型的普通车床,要完成今年的大型机床任务,便有很多客观困难,主要是厂房比较低矮简陋,不能装配大型机床;没有起重设备;更缺乏加工大机床部件的设备。因此在制造2公尺落地车床的时候,便碰到一些关键问题,一时得不到解决。这台落地车床的车头箱重三噸,要镗17个孔与括平面,厂里只有一台φ90公厘的“老爷”镗床,效能非常的低,操作又不方便,第一台的镗孔时间足足化了六天六夜。后来虽经工人同志
In the past, Shanghai Ming Jing Machine Tool Factory had been producing small and medium-size general lathes in the past. To accomplish this year’s large-scale machine tool tasks, there were many objective difficulties. The main problems were the relatively low-level workshops, the inability to assemble large machine tools, the lack of lifting equipment and the lack of processing Large machine parts of the equipment. Therefore, when manufacturing a 2-meter floor-standing lathe, it encountered some key problems that could not be solved for a time. This floor lathe front box weighing three tons, to bored 17 holes and including the plane, the factory only one φ90 mm “master” boring machine, the performance is very low, the operation is not convenient, the first boring Time is full six days and six nights. Later, though the workers comrades
