HYDROSTATIC PRESSURE GUIDE MECHANISM AND MACHINE TOOL |
| 摘要 |
A hydrostatic pressure guide mechanism includes: a guide member having a smooth guide surface; a movement member having a slide surface facing the guide surface and an annular placement groove formed on the slide surface; an annular seal member (hermetically closing member) that is disposed in the placement groove and capable of hermetically contacting with the guide surface; an oil supply structure configured to supply an oil into a static pressure pocket on the slide surface surrounded by the seal member; and an oil recovery structure configured to recover the oil from the static pressure pocket, in which the oil recovery structure has a recovery hole that is formed in the static pressure pocket and is opened on the slide surface. |

1. A hydrostatic pressure guide mechanism comprising:
a guide member having a smooth guide surface; a movement member having a slide surface facing the guide surface and an annular placement groove formed on the slide surface; an annular hermetically-closing member that is disposed in the placement groove and capable of hermetically contacting with the guide surface; an oil supply structure configured to supply oil into a region on the slide surface surrounded by the hermetically closing member; and an oil recovery structure configured to recover the oil from the region on the slide surface surrounded by the hermetically closing member, wherein the oil recovery structure comprises a recovery hole that is formed in the region on the slide surface surrounded by the hermetically closing member and is opened on the slide surface. |
