C616车床主轴传动由于缺乏制动装置,主轴甩车较大。为了提高生产效率,操作者常常熟练地利用反车进行制动,从而导致机床变速箱超负荷,使齿轮等零件损坏。经我厂使用的五台C616车床计算,去年用去的维修时间为278小时,其中变速箱故障共16次,计148小时,平均30时/台,是我厂一般机床停机维修时间的三倍之多。因此,这一机构 C616 lathe spindle drive due to the lack of braking device, spindle rejection car larger. In order to improve production efficiency, operators often skillfully use the anti-vehicle brake, resulting in overload machine tool transmission, gear and other parts damaged. The calculation of the five C616 lathes used by our factory was 278 hours last year, of which gearbox failures totaled 16 times in 148 hours, an average of 30 hours / station, which is three times the downtime of the general machine tool in our factory Much. So this body
