Universal gear grinding machine ZE40A


Capable of Grinding a Wide Variety of Workpiece in Generating and Form Grinding Methods

  • Both generation grinding and profile grinding are available.
    (Grinding wheel is dressed to any desired shape as mounted on the machine to tackle complex tooth profile modification)
  • Grinds workpieces with Φ400 mm external diameter (Φ600 mm at maximum)
  • 400-mm axial stroke facilitates grinding shaft workpieces
  • Module 0.5 to 8 supported.
  • With the tooth shape modification function and the bias modification function, the machine grinds various types of gear profile.

Simple Setup Change Facilitates Small Volume Production

  • Simple compensation function that facilitates precise machining from the first workpiece
  • Tooth meshing between the grinding wheel and the dresser, as well as between the grinding wheel and the workpiece, during setup are automated.

Measuring Device (Equipped inside the Machine) Optionally Available

  • A newly developed high-speed, high-accuracy workpiece measuring device that is equipped inside the machine is available.
  • By automatically calculating compensation amount from the measurement results, the device facilitates precision machining of large-diameter workpieces that require long setup time.
