Gear tooth and thread grinding machine

abcdThe invention concerns a machine for the chip-forming machining and the measurement of gears and screw-type workpieces. Arranged on a swivel head swivellable about an axis (A) at right angles to the rotary axis of the workpiece are functional units with machining and measuring tools which are displaceable radially and parallel relative to the swivel axis (A), which said tools can be brought consecutively into engagement with the workpiece, thus making possible the application of different tools and machining techniques in the same work set-up without colliding. The work spindle is driven by electric motor either directly or via a gear unit.
