Abstract
The motion system for a CMM includes a measuring axis with an air bearing, a control unit for determining a position of the measuring probe in a reference frame and outputting the position as a measuring result. The first air bearing includes a guideway, slide having a slide surface and a gas outlet within the slide surface. The gas outlet is for providing a gas cushion in a gap between the slide surface and the guideway. A cover is arranged around the slide so a gap is provided between the cover and the guideway and a hollow space is provided between the cover and the slide. A wiper is arranged on the cover. A nozzle unit is supplied by a second gas supply line and for providing a high-pressure gas flow directed onto the guideway.
