由于新机床的供应量远远满足不了机器制造业发展的需要,所以即使在航空工业,在生产第一线已服役二、三十年的旧机床也还不能退伍,看来还得继续再使用一个相当长的阶段。这样就使各厂的机修工作极其繁重。在航空工厂,除产品车间各有维修组外,还都有专门的机修车间,承担机床的大、中修任务。从机修工人的数量看,大概不会少于直接生产工人的五分之一,并且技术等级普遍较高。但机修质量往往并不理想。所以有些使用单位反映
As the supply of new machine tools can not meet the needs of the machine manufacturing industry, even in the aviation industry, old machines that have been in production for 20 to 30 years at the front line of production can not be retired and it seems that they have to continue to use them A fairly long period. This made the mechanics of the plants extremely heavy. In the aviation factory, in addition to the repair shop each product group, but also have a special machine shop, bear the machine tool, repair tasks. From the number of mechanics, probably no less than one-fifth of the direct production workers, and generally higher technical grade. However, the quality of the mechanics is often not ideal. So some use units reflect
