The five-axis high-speed precision-machining numerical control machine tool comprises a T-shaped machine tool bed, the machine tool bed comprises a transverse machine tool bed body in an X-axis direction and a vertical machine tool bed body in a Y-axis direction, slide rails are arranged on both of the transverse machine tool bed body and the vertical machine tool bed body, and high-precision roller linear guide rails are adopted to serve as the slide rails. The five-axis high-speed precision-machining numerical control machine tool has the advantages that the machine tool is arranged in a high-reinforcement structure and subjected to multiple times of artificial aging treatment so as to achieve high vibration resistance and high rigidity and ensure machining precision and long-term stability; the high-precision roller linear guide rails are adopted on the machine tool bed bodies in the X-axis direction, the Y-axis direction and a Z-axis direction to achieve high rigidity, low noise, small frictional characteristic, precise positioning and the like, quick movement is achieved, machining efficiency and part size precision are improved substantially, and yield of machine tool products is increased.

Description

technical field [0001] The invention relates to the field of machining, in particular to a five-axis high-speed precision machining numerical control machine tool. Background technique [0002] CNC machine tools are entering the era of high-speed machining. The rapid movement and positioning of the moving parts of CNC machine tools and high-speed cutting processing have greatly improved productivity. CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The range of sound speed and feed rate of the spindle of CNC machine tools is large, which allows the machine tool to perform powerful cutting with large cutting volume. The indicators of machine tool technical performance can ultimately be attributed to machining accuracy and production efficiency. Machining accuracy includes the dimensional accuracy, shape accuracy, position accuracy, surface quality and accuracy retention of the machine tool to be processed. [0003] The unreasonable d...

Problems solved by technology

[0003] The unreasonable design of the guide rail structure of the existing CNC machine tools results in defects such as high noise and friction during the processing process, and it is difficult to guarantee the processing accuracy of the parts, which eventually leads to a high frequency of equipment failures, and the parts are scrapped because the processing accuracy does not meet the requirements. Thereby seriously affecting the improvement of work efficiency and economic benefits of enterprises
