Spindle Motor Of Machining Center

Development Trends:

1. Firstly, the adoption of linear motor drive technology. After more than a decade of development, linear motor technology has become very mature. The issues of susceptibility to interference and high heat generation that were present when linear motors were first developed have been resolved. Additionally, the precise positioning technology of linear motors, which allows for rapid stopping at ultra-high speeds, has been addressed by some gear manufacturers through the use of damping technology.

The advantages of linear motors include linear drive, no transmission gears, no wear, and no backlash, which enables them to achieve excellent precision levels. Linear motors have high dynamics, with instantaneous acceleration exceeding 3g. The use of linear motor drives also offers high reliability and maintenance-free characteristics.

1. Secondly, the adoption of dual-drive technology. For wider worktables or gantry crane configurations, if central drive is used, it is difficult to ensure that the driving force is centered, which can easily lead to tilting and weak dynamic performance. By using dual drives, dual gratings, and a single drive control module, nearly perfect dynamic performance can be achieved. With a single drive command, the dual drives work simultaneously, and the gratings are used to detect whether the two points are balanced. If they are not balanced, different commands are used to achieve balance. Of course, the development trends of five-axis simultaneous machine tool technology extend far beyond these, and many of these technologies are likely to be reflected in DMG MORI's CNC machine tool products.
