Description

Technical Field

[0001] The utility model relates to the technical field of precision mechanical engineering, in particular to a high-precision numerical control cutting machine tool for precision mechanical engineering. Background Art

[0002] Precision machining is a process of changing the shape, size or performance of a workpiece by using machining machinery. According to the temperature state of the workpiece being machined, it is divided into cold machining and hot machining. Generally, machining at room temperature does not cause chemical or phase changes in the workpiece, which is called cold machining. Generally, machining at a temperature higher or lower than room temperature will cause chemical or phase changes in the workpiece, which is called hot machining. Cold machining can be divided into cutting machining and pressure machining according to the difference in machining methods. Common hot machining includes heat treatment, forging, casting and welding. CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, and decode them, express them in coded numbers, and input them into the CNC device through the information carrier. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically machine the parts according to the shape and size required by the drawing. CNC cutting machine tools are required for cutting precision mechanical parts.
