The development trend of entrepreneurial five-axis CNC machine tools?

2022-04-06

1. The pioneering five-axis CNC machine tool firstly adopts linear motor drive technology. After more than ten years of development, the linear motor technology has become very mature. The problem that linear motors are susceptible to interference and large heat generation has been solved. The positioning technology of linear motors not only stops quickly during high-speed movement, but also some machine tool manufacturers use damping technology to solve them. The advantages of linear motors are linear drive, no transmission chain, no wear, and no backlash, so they can achieve the best positioning accuracy. Linear motors are highly dynamic, with accelerations exceeding 2g. The use of linear motor drive also has the characteristics of high reliability and maintenance-free.

2. If the entrepreneurial five-axis CNC machine tool adopts the intermediate drive, it is impossible to ensure that the driving force is in the center, which is easy to cause inclination and poor dynamic performance. With dual drives, dual gratings, and one drive module, the dynamic performance is perfect. One drive command, the two drives work at the same time, the grating ruler detects whether the two points are balanced, and if they are not balanced, they are balanced by different commands. Of course, the development of five-axis linkage machine tool technology is far more than that, and many technologies will be reflected in future machine tool products.
