Abstract
A guide mechanism for a machine tool includes a movement member and a guide member in a form of first and second rails the movement member and the guide member relatively movable to each other. A hydrostatic pressure guide mechanism and a sliding guide mechanism are formed between the movement member and the first and second rails. The hydrostatic pressure guide mechanism includes a static pressure chamber, a seal portion sealing a periphery of the static pressure chamber, and a supply passage configured to supply a lubricating oil into the static pressure chamber.
