Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically to a CNC machine tool that can be used for both vertical and horizontal machining. Background Technology

[0002] General-purpose CNC machine tools primarily operate on three axes: X, Y, and Z. For workpieces requiring machining multiple faces, a fourth axis is often added. However, this introduces limitations during machining, and accuracy cannot be guaranteed precisely due to clamping methods and stress factors. Therefore, it has limitations for high-precision multi-faceted machining of parts. Commonly used three-axis machine tools cannot meet the precision requirements of high-precision multi-faceted parts. Adding an external fourth or fifth axis also faces constraints. Therefore, a CNC machine tool capable of handling multi-faceted machining with guaranteed accuracy is needed. Utility Model Content

[0008] Compared with the prior art, the beneficial effects of this utility model are: after the workpiece is clamped, the rotary machine tool and the crossbeam work together to process multiple surfaces, and then the machine tool is controlled to move along the gantry linear guide to the horizontal machining base to complete the processing of the remaining unprocessed surfaces of the workpiece. Thus, at least five surfaces of the workpiece can be processed, which provides high processing flexibility and greatly improves the processing efficiency of the workpiece, meeting the processing requirements of customers.
