The reasons for selecting open or closed hydrostatic guideway on the CNC double column boring and milling machine were discussed. 并對數控龍門鏜銑床床身工作臺導軌副采用開式或閉式靜壓導軌的理由分別進行了論述。
From the simulation result, straightness error is affected by guideway parallel, and the suitable pre-load can improve the error effectively. 經由模擬結果得知，導軌圓軸平行度為影響直線度誤差的主要原因，此外，適當的彈簧預壓力能有效的減少直線度誤差。
