ABSTRACT:
A coordinate measuring machine with a drive and braking arrangement for a spindle sleeve which is displaceable in the Z-direction through the intermediary of a threaded spindle. A motor power output or take-off shaft and the threaded spindle, which are arranged axially-parallel relative to each other, are in a driving connection with each other through the interposition of a belt drive with a belt tensioning and supervisory or monitoring arrangement, whereby a brake pulley is flange mounted to the belt pulley for the drive of the threaded spindle, and a braking clamp or a disc brake acts on the brake shoes.
