Description

Technical Field

[0001] The utility model relates to the technical field of machine tool lubrication, in particular to a machine tool lubrication system. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program control system, which solves the problem of complex, precise, small-batch, and multi-variety parts processing. The most common existing CNC machine tools are three-axis CNC machine tools and five-axis CNC machine tools, that is, each axis can move in one direction to achieve processing of parts in all directions. The axis of the machine tool is a lead screw design, which controls the stable movement of the part processing mechanism by rotating the lead screw and coordinating the limit of the sliding shaft. In order to ensure the accuracy of the processing, the lead screw and sliding shaft need to be lubricated with lubricating oil to reduce the friction resistance when the part processing mechanism moves.
