摘要

The table (2) is used to support the workpiece. A flow generating device produces a gas flow on the top side (17.1, 17.2) of the table in the region between the workpiece and the top side of the table, on which the workpiece is arranged during machining. The support surface consists of at least two sectors in longitudinal sequence, separated by a gap (16). Outflow apertures (15) guide gas under pressure to create a gas cushion between the surface sector and the underside of the workpiece.
