Title:

Document Type and Number:

WIPO Patent Application WO/2022/205542

Kind Code:

A1

Abstract:

A negative-pressure adsorption static-pressure supporting guide rail of a machining machine tool, comprising a guide rail groove (1), a guide rail body, and a static pressure supporting assembly. The guide rail groove (1) is fixedly formed in the lower side surface of a workbench; the guide rail body is fixedly provided on the upper side surface of the machine tool; and the guide rail groove (1) is disposed corresponding to the guide rail body. By means of the static-pressure supporting assembly, the guide rail groove and the guide rail body are in a pure liquid friction state, so that the machining machine tool has the advantages of high motion precision, low friction resistance, and the like. Further provided is a cylindrical grinding machine comprising the negative-pressure adsorption static-pressure supporting guide rail.
