Compact cross table, linearmotor driven

SKF positioning systems designed a series of compact cross tables that are driven with ironless linearmotors. High guiding / positioning accuracy and high dynamic lead to a perfect solution for wafer measurement. The free area through the whole unit optimizes the mounting position of the measurement device.
