Large dia-size gear shaping machine SEA1600


Processes both internal and external gears for workpieces up to diameter of φ1600 mm and a gear width of up to 350 mm.

  • A 800 mm axial stroke enables the use of workpieces of a wide range of specifications.

Main spindle quick return mechanism included as standard equipment.

  • A new main spindle quick return mechanism and reduced return time for the special gear-shaper cutter enable cycle time to be shortened by 10 to 30%.

(Options) An optional ATC can be added, and a stocker for four sets of cutter arbors is available for the rear of the machine.

  • Change even large, heavy cutters easily and automatically.
  • Auto switch between rough and finishing cutters, even during the processing cycle.

(Option) A base tangent length measuring device can also be installed, with the measurement probe moved and measured using a 2-axis NC.

  • Final processing based on in-process measurements achieves target tooth thickness in one cycle.
  • Manually switch between internal-external gear measurements.
