What is the multi-axis CNC machining technology like?

Mar 27, 2021

As the basis of modern mechanical manufacturing technology, CNC machining technology has caused significant changes in the mechanical manufacturing process. Compared with traditional processing technology, modern numerical control processing technology is significantly different in many aspects such as processing technology, processing process control, or processing equipment and process equipment. We know clearly that CNC machine tools have three linear coordinate axes, X, Y, and Z. Multi-axis means that a machine tool has at least the 4th axis. Generally speaking, multi-axis CNC machining refers to CNC machining with more than 4 axes, and the representative is 5-axis CNC machining.

Multi-axis CNC machining can control the linkage of more than 4 coordinate axes at the same time, combining CNC milling, CNC boring, CNC drilling and other functions together. After a workpiece is clamped, the machining surface can be milled, bored, and drilled. Process processing effectively prevents positioning errors caused by multiple installations, reduces the production cycle, and improves processing accuracy. With the rapid development of production model manufacturing technology, higher requirements are put forward for the processing experience and processing efficiency of the machining center, and this multi-axis CNC machining technology has been better developed.

With the development of CNC technology, multi-axis CNC machining centers are becoming more and more widely used. Their biggest advantage is that they make the processing of originally complex parts a lot easier, moreover, they reduce the processing cycle and improve the surface processing quality. The use of five-axis linkage machine tool processing can quickly complete the production model processing, fast delivery, better guarantee the processing quality of the production model, and make the processing easier. In the traditional production model processing, the vertical machining center is also used to complete the milling of the workpiece. With the continuous development of production model manufacturing technology, some of the weaknesses of the vertical machining center itself have become more and more obvious. In modern production model processing, ball-end milling cutters are widely used for processing. The benefits of ball-end milling cutters in production model processing are very clear. However, if a vertical machining center is used, the linear velocity of the bottom surface is zero, so that the bottom surface The finish is very poor. Assuming the use of four- and five-axis linkage machine tool processing technology to process production models, the above-mentioned insufficiency can be overcome.
