Machine tool industry

In CNC machine tools, the AC servo electric machine tool worktable is mainly used for motion control. In order to display or control the displacement of the machine tool worktable, it is often necessary to convert it into a digital quantity. For this purpose, position sensors are required. Commonly used ones include code disks, induction synchronizers, synchronizers and gratings, etc. CNC machine tools generally use code disks and gratings (hereinafter referred to as encoders) for position detection.
