去年我厂在WX009深孔磨床、M7120A平面磨床、M1432B外圆磨床、M6025C和M612万能工具磨床等五种型号的六台机床上,成功地应用了液体静压轴承,效果良好。改造后的磨床主轴回转精度,都有大幅度的提高,振摆量在5微米以内;磨削光洁度在▽9～▽11, Last year, we successfully applied hydrostatic bearing on WX009 deep hole grinder, M7120A surface grinder, M1432B cylindrical grinding machine, M6025C and M612 universal tool grinder, and achieved good results. After the transformation of the grinding spindle rotation accuracy, have a substantial increase in the amount of vibration within 5 microns; grinding finish in ▽ 9 ~ ▽ 11,
