日本岡本(Okamoto)公司生产的PSG-52 UAN型卧轴矩台平面磨床(图1)结构紧凑、操作方便。它的结构特点是磨头前后位置固定不动,主轴用高精度滚动轴承,回转精度稳定在0.02μm左右;以十字导轨形式使负荷承载面积大,位置稳定性好;配备薄壁型工作台及滑鞍座,高度位差润滑,使工作台浮起量为5μm,工作台的运动灵敏稳定;被磨工件直线性精度可达0.003mm/500mm,表面粗糙度R_α0.1μm;工作台纵向运动和滑鞍横向运动时导轨都可悬
Japan Okamoto (Okamoto) company’s PSG-52 UAN horizontal axis moment table grinder (Figure 1) compact structure, easy to operate. Its structure is characterized by fixed position before and after the grinding head, the spindle with high-precision rolling bearings, slewing accuracy of about 0.02μm; cross-rail form to load carrying area, good position stability; with thin-walled workbench and slide Saddles, a high degree of error lubrication, the table floating amount of 5μm, the worktable motion sensitive and stable; workpiece straightness accuracy of up to 0.003mm / 500mm, surface roughness R_α0.1μm; table longitudinal and sliding Saddle rail lateral movement can be suspended
