Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, specifically to a CNC machine tool for metal product processing. Background Technology

[0002] In metal product processing, CNC machine tools and CNC lathes are required, mainly used for machining rotating parts such as shafts and discs. They can perform various machining operations such as turning external diameters, internal holes, threads, and conical surfaces. The CNC system controls the movement trajectory of the cutting tool to achieve high-precision machining. CNC machine tools are widely used in metal product processing.

[0003] Existing CNC machine tools for metal product processing still have the following problems when in use: their clamping time is long. In order to ensure machining accuracy, the clamping and preparation of parts on the machine tool is relatively cumbersome and takes up a lot of time. In addition, when adjusting the position of the machining tool mechanism, it is mainly a horizontal position adjustment, which is usually a lead screw assembly. The transmission efficiency of the lead screw assembly is limited. During the lead screw transmission process, there is a lot of friction between the lead screw and the nut, especially at high speed, which generates a large frictional force, resulting in a reduction in transmission efficiency. In addition, its load capacity is limited, which may become a limiting factor. Utility Model Content
