我厂生产CW6143普通车床,过去珩磨尾座孔是在摇臂钻床上借助简易的珩磨工具进行人工珩磨,工效低、劳动强度大,且孔的光洁度和精度都很差,不能满足生产的需要。为了解决生产的急需,我厂于1974年10月制成一台立式液压珩孔机床,完成一件尾座孔的珩磨只需一人操作5～6分钟,大大提高了工效,改善了劳动条件,提高了珩孔质量。在掌握合理的珩磨工艺条件下,孔的椭圆度及不同心度均可控制在0.01毫米以内,光洁度可达 I plant CW6143 ordinary lathe production, honing tailstock hole in the past on the radial drilling machine with a simple honing tool for artificial honing, low efficiency, labor-intensive, and the hole of the finish and accuracy are poor, can not meet the production needs. In order to solve the urgent need of production, I plant in October 1974 made a vertical hydraulic honing machine, finishing a tail hole honing only one person operation for 5 to 6 minutes, greatly improving the work efficiency and improve working conditions , Improve the honing quality. In a reasonable honing process conditions, the hole ovality and different heart can be controlled within 0.01 mm, the finish up
