卸荷式静压导轨在数控铣磨机床上的应用

Application of Unloading Hydrostatic Slide of CNC Milling-Grinding Machine

介绍液体卸荷式静压导轨应用于数控龙门铣磨机床的优点,根据数控龙门铣磨机床的整体结构方案及其导轨的工况确定了卸荷式静压导轨的结构方案,选用开式卸荷式静压导轨,提高导轨运动精度,使其运行平稳,并能长期保持制造精度。

The advantages of the unloading hydrostatic slide which was applied in the CNC Milling-Grinding Machine are introduced. The structure scheme of the unloading hydrostatic slide is determined based on the whole structure scheme and the guide＇s working condition of the CNC Milling-Grinding Machine. The open-hydrostatic guideways design is selected. It can improve the accuracy of rail movement and move smoothly. It can also keep accuracy in long term.
