A brief introduction to multi-axis CNC machining technology

Multi-axis machining should be precisely multi-coordinate linkage machining. At present, most control processing equipment can realize up to five coordinate linkage. There are many types of such equipment, and the structure type and control system are different. As the basis of modern mechanical manufacturing technology, CNC machining technology has made significant changes in the mechanical manufacturing process. Titanium Machinery is the main product of the company with rotary top, screw, shaft machining, CNC lathe machining, shank shank and collet post. Compared with traditional machining technology, modern CNC machining technology is processed. Process control, as well as processing equipment and process equipment, are significantly different. The CNC machine we are familiar with has three linear axes of XYZ, and the multi-axis refers to at least the 4th axis on one machine. The so-called multi-axis CNC machining refers to CNC machining of more than 4 axes, and the representative one is 5-axis CNC machining. Multi-axis CNC machining can simultaneously control the linkage of more than 4 coordinate axes, and combine the functions of CNC milling, CNC boring, CNC drilling, etc. After the workpiece is clamped, the workpiece can be milled, boring, drilling and other processes. The machining effectively avoids the positioning error caused by multiple installations, shortens the production cycle and improves the machining accuracy. With the rapid development of mold manufacturing technology, the processing capacity and processing efficiency of the machining center are put forward higher requirements, so the multi-axis CNC machining technology has achieved unprecedented development. With the development of numerical control technology, multi-axis CNC machining centers are getting more and more widely used. Their greatest advantage is that it makes the processing of the original complex parts much easier, and shortens the processing cycle and improves the processing quality of the surface. The improvement of product quality has improved the performance requirements of the products, such as the finishing of the lamp mould and the headlight mould of the car: the machining of the five-axis linkage machine with double turntable, due to the special optical effect requirements of the headlight mould, many small curved pairs for reflection The precision and finish of the processing have very high index requirements, especially the finish, which is almost required to achieve a mirror effect. It is easy to cut the mirror surface with a high-speed cutting process equipment and a five-axis linkage machine with a ball milling cutter, and the backward processing technology in the past is almost impossible to achieve. The use of five-axis linkage machine tool can quickly complete the mold processing, fast delivery, better guarantee the processing quality of the mold, make mold processing easier, and make mold modification easier. In the traditional mold processing, the vertical machining center is generally used to complete the milling of the workpiece. With the continuous development of mold manufacturing technology, some weaknesses of the vertical machining center itself are becoming more and more obvious. Modern mold processing is generally processed by ball-end milling cutters. The benefits of ball-end milling cutters in mold processing are very obvious, but if a vertical machining center is used, the bottom line has zero line speed, so the bottom surface has a poor finish. If the four or five-axis linkage machining technology is used to process the mold, the above shortcomings can be overcome.
