在贯彻JB 1577～1578-75卧轴矩台平面磨床精度标准过程中,由于磨头体的φ280 D-φ 270D-φ190 D1三连孔轴心线对 55°燕尾导轨的平行度严重超差(见图1“×”),为了达到磨头横向移动对工作台纵向移动的垂直度0.04/300mm(第 6项精度)和砂轮轮中心线对工作台纵向移动的垂直度 0.04
In the implementation of JB 1577 ~ 1578-75 horizontal axis moment table grinder accuracy standards, because the grinding body φ280 D-φ270D-φ190 D1 triple hole axis of the 55 ° dovetail rail parallelism serious tolerance See Fig. 1 “×”). In order to achieve 0.04 / 300mm (item 6) of the vertical movement of the grinding head in the longitudinal direction of the table and the verticality of the grinding wheel centerline to the longitudinal movement of the table by 0.04
