n.導(dǎo)軌

The reasons for selecting open or closed hydrostatic guideway on the CNC double column boring and milling machine were discussed. 并對(duì)數(shù)控龍門(mén)鏜銑床床身工作臺(tái)導(dǎo)軌副采用開(kāi)式或閉式靜壓導(dǎo)軌的理由分別進(jìn)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(jīng)由模擬結(jié)果得知，導(dǎo)軌圓軸平行度為影響直線(xiàn)度誤差的主要原因，此外，適當(dāng)?shù)膹椈深A(yù)壓力能有效的減少直線(xiàn)度誤差。
