Description

Technical Field

[0001] The utility model relates to the technical field of machining machine tools, in particular to an assembly and adjustment device for a screw feeding mechanism. Background Art

[0002] During the processing of CNC precision machine tools, the friction between the screw and the nut causes the temperature to rise, which causes the screw to stretch due to the temperature rise, resulting in errors in the machine tool accuracy.
