The reasons for selecting open or closed hydrostatic guideway on the CNC double column boring and milling machine were discussed. 并对数控龙门镗铣床床身工作台导轨副采用开式或闭式静压导轨的理由分别进行了论述。
From the simulation result, straightness error is affected by guideway parallel, and the suitable pre-load can improve the error effectively. 经由模拟结果得知，导轨圆轴平行度为影响直线度误差的主要原因，此外，适当的弹簧预压力能有效的减少直线度误差。
