ABSTRACT:
The invention is of an X-Y coordinate positioning device, in which a U-shaped profiled rail is placed on a worktable. Within this rail, a lengthwise slide is moved along the X-coordinate by a first linear drive system driven by a stationary motor. Mounted on this lengthwise slide is a cross-slide for motion along the Y-coordinate. The cross-slide is moved by a second motor-driven linear drive system. In order to reduce the inertial loads, the second linear drive system includes a stationary stepping control motor, which drives a profiled toothed belt. The toothed belt engages toothed guide rollers at the ends of the cross-slide.
