Introduction to the knowledge of five-axis linkage machine tools
First, the advantages The use of a five-axis linkage machine makes it easy to clamp the workpiece. No special fixture is needed during processing, which reduces the cost of the fixture, avoids multiple clamping and improves the precision of the mold processing. Machining molds with five-axis technology can reduce the number of fixtures used. In addition, because the five-axis linkage machine saves many special tools during machining, the tool cost is reduced. The five-axis linkage machine tool can increase the effective cutting edge length of the tool during machining, reduce the cutting force, improve the tool life and reduce the cost. Using a five-axis linkage machine tool to process the mold 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. Second, the type The five-axis linkage machine has vertical, horizontal and cradle two-axis NC table, NC table NC indexing head, NC table 90 axis, NC table 45B axis, NC table A axis, two-axis NC spindle, etc. Types of. There are 7 kinds of five-axis linkage modes in the above six categories, each with its own characteristics. It can't be said which form is better. It can only be said which type of 5-axis machining is suitable for your product. Third, the trend of development 1. The first is to use linear motor drive technology. After more than ten years of development, linear motor technology has been very mature. The problem that the linear motor has just been developed to be susceptible to interference and large heat generation has been solved, and the positioning technology of the linear motor is quickly stopped in high-speed movement, and some machine tool manufacturers use damping technology to solve it. 2, followed by the use of dual drive technology. For the wider workbench or gantry type, if the intermediate drive is used, the driving force is not guaranteed to be at the center, which tends to cause tilting, resulting in poor dynamic performance. With dual drives, dual scales and a drive module, dynamic performance is perfect. A drive command, the dual drive works at the same time, the grating ruler to detect whether the two points are balanced, if it is unbalanced, it is balanced by different instructions. Of course, the development of five-axis linkage machine technology is far more than that, and many technologies will be reflected in DMG's machine tools.

Linear motors have the advantages of linear drive, no drive chain, no wear and no backlash, so they can achieve the best positioning accuracy. Linear motors have high dynamics and accelerations can exceed 2g. The linear motor drive also features high reliability and maintenance-free operation.
