我厂在以提高产品质量为中心的增产运动中,对龙门刨床的主要零件(如床身、立柱、横梁等)提出了中间公差的要求,即在原图纸规定的基础上,提高四分之一的精度要求。为了达到中间公差,我们采取了各种措施,总结了工人在龙门刨床上磨削加工的经验。现将床身导轨磨削加工的一些经验介 I plant in order to improve product quality as the center of the increase in production campaign, the main planer planing machine parts (such as bed, column, beams, etc.) put forward the requirements of the middle tolerance, that is, the provisions of the original drawings, an increase of one-fourth The accuracy requirements. In order to achieve intermediate tolerances, we have taken various measures to summarize the workers’ experience of grinding on a planer. Now the bed rail grinding experience of some medium
