Abstract: A linear guide for a coordinate measuring machine. The linear guide comprises at least one plate-shaped main body and at least one guide rail. The plate-shaped main body has a material with a first coefficient of thermal expansion. The at least one guide rail has a material with a second coefficient of thermal expansion, which differs from the first coefficient of thermal expansion. The guide rail is connected to the plate-shaped main body, and arranged in a neutral axis of the plate-shaped main body.

Abstract: A coordinate measuring equipment has at least one part that is movably guided on a guideway for measuring a workpiece and a drive for moving the part along the guideway. The drive for moving the part is connected to the guideway by means of a frictional connection.

Abstract: A spindle drive for a coordinate measuring machine, wherein a spindle nut which is fastened within a receiving member is seated on a driven threaded spindle. Intermediate the receiving member and a retaining member, the spindle is fixedly connected with a component which is to be driven, through the interposition of roll bodies for producing a compensating clearance radially relative to the spindle axis and a compensating or equilibrating for wobbling motions of the spindle.

Abstract: A coordinate measuring machine with a base frame which is essentially constructed in the mode of a portal or gantry-type structure which concurrently forms a measuring table, and with a cross-carrier which spans over the measuring table and receives a measuring carriage with a spindle, and which supports itself with one arm on a guideway located in front of the measuring table.

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.
