Abstract
The invention concerns a machine for the chip-forming machining and the measurement of gears and screw-type workpieces. Arranged on a swivel head (6) swivellable about an axis (A) at right angles to the rotary axis of the workpiece (4) are functional units (8a, 8b, 8c, 8d) with machining and measuring tools (10, 12, 14, 15, 17) which are displaceable radially and parallel relative to the swivel axis (A), which said tools can be brought consecutively into engagement with the workpiece (4), thus making possible the application of different tools (10, 12, 14, 15, 17) and machining techniques in the same work set-up without colliding. The work spindle (1) is driven by electric motor either directly or via a gear unit.
Claims19
Machine for the chip-forming machining of gears and screw-type workpieces, comprising:
- a. a work spindle for the accommodation of a gear or screw-type workpiece to be ground, the said spindle being located for rotation about a first axis on a first slide,
- b. a machine bed bearing the first slide, the first slide being displaceable parallel to the first axis, and
- c. a swivel head located for rotation about a second axis,
- wherein on the end front face of the swivel head directed towards the work spindle at least two, preferably four functional units are arranged, which are equipped with machining tools or measuring tools and wherein at least two of said functional units are arranged displaceable relative to the swivel head, where by displacement relative to the swivel head and by swivelling of the swivel head said at least two functional units can be brought as required into active connection with the gear or screw-type workpiece to be machined.
