摘要

"WORKING PARTS ON A TOOL, SUBSTANCES FOR A WORKING TABLE, AND METHODS OF OPERATING A WORKING TABLE, AND CALIBRATING A TOOLING TABLE". A workpiece clamping table (1) is disclosed in a machine tool which includes a plurality of mutually juxtaposed clamping elements (3) which each have a respective tube tube unit. (10) with a top end suction plate (11), the concentric tubes (13, 14) of the telescopic tube unit (10) being displaceable relative to one another by means of a positioning drive ( 12), the positioning drive (12) is arranged coaxially with respect to the telescopic tube unit (10) and is or releasably coupled with the displaceable telescopic tube (13) by means of a positive locking buffer coupling (21, 25). or is permanently coupled to the displaceable telescopic tube (13), and is electrically connected to a power supply (53) via a releasable plug connection (50, 52).
