我厂过去用普通车床车削轴瓦内、外圆时,操作频繁,劳动强度大,效率低,机床床身容易磨损。为改变这一落后状态,我厂机械加工车间的工人和技术人员破除迷信,解放思想,大胆革新,终于试制成功无床身液压传 In the past, our factory used common turning lathe to make the inner and outer circles of the bearing. The operation is frequent, the labor intensity is high, the efficiency is low, and the machine bed is easy to wear. In order to change this backward state, the factory workers and technicians in the mechanical processing workshop got rid of superstition, emancipated their minds, boldly innovated, and finally succeeded in trial-manufacture without bed hydraulic pressure transmission
