Abstract
Official abstract text for this publication.
The invention provides a machine tool capable of expanding the slidable range of the moving unit without making the oil feeding system complicated. A machine tool in which a moving unit slides against a supporting unit with a sliding surface of the supporting unit facing a sliding surface of the moving unit, comprises a first oil groove formed on an unexposed portion of the sliding surface of the supporting unit; a second oil groove formed on an unexposed portion of the sliding surface of the moving unit; and an oil inlet formed on one of the first oil groove and the second oil groove. Lubricant fed through the oil inlet is supplied to the other of the first oil groove and the second oil groove.
First claim
Opening claim text (preview).
What is claimed is: 1. A machine tool in which a moving unit slides against a supporting unit with a sliding surface of the supporting unit facing a sliding surface of the moving unit, the machine tool comprising: a first oil groove formed on an unexposed portion of the sliding surface of the supporting unit; a second oil groove formed on an unexposed portion of the sliding surface of the moving unit; and an oil inlet formed on one of the first oil groove and the second oil groove, wherein the first oil groove and the second oil groove are arranged to have an intersection therebetween and wherein lubricant fed through the oil inlet is supplied to the other of the first oil groove and the second oil groove via the one of the first oil groove and the second oil groove and the intersection. 2. The machine tool of claim 1 wherein the moving unit slides against the supporting unit within a predetermined range, a lowermost part of one of the first oil groove and the second oil groove is in a position not higher than a lowermost part of the other of the first oil groove and the second oil groove, and the oil inlet is formed on the lowermost part of the one of the first oil groove and the second oil groove.
