Document Type and Number:
WIPO Patent Application WO/2023/171601
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide: a machine tool system in which a machine tool lubricant that contains no oil-soluble material derived from mineral oil is cyclically used; and a hydraulic liquid and a processing liquid for machine tools. [Solution] This machine tool system is for employing a machine tool that operates under an environment in which a hydraulic liquid gets mixed with a processing liquid used for the processing of members to be processed by the machine tool. In the machine tool system, water-soluble materials that contain no oil-soluble material derived from mineral oil are used for both the hydraulic and processing liquids. The machine tool system comprises: a recovery means which is installed on the downstream side of a lubricant flow channel in the machine tool where the hydraulic and processing liquids are mixed and recovered after exhibiting a lubricating effect; a discharge container which is in communication with the recovery means and which is for accumulating the hydraulic and processing liquids; and a circulation means that suctions, in an intact form without causing oil-water separation, the hydraulic and processing liquids from an inflow port disposed inside the discharge container at a location away from the bottom, and that returns the hydraulic and processing liquids to a processing liquid feed passage and/or a hydraulic liquid feed passage.
