Efficient Precision Grinding

  • A direct drive system powered by a built-in motor is employed for the dresser. High-precision dressing finish is possible thanks to high degree of vibration suppression.
  • The turning table employs motor direct drive (DD) system, hydrostatic bearings, and high-precision scale that, along with the dresser, contribute to high-accuracy, highly-efficient machining.

Drastically Shortened Non-Cutting Time Improves Productivity

  • Equipped with machining path optimization function that estimates the grinding stock of all teeth based on automatic meshing data.
  • Equipped with eccentricity compensation function that measures error in workpiece positioning and offsets it in the machining operation. (Reduced setup time)
  • High-speed, high-precision measurement by means of new measurement method.
  • An ample work space is secured around the table to facilitate workpiece and jig changeover.

Large Color LCD Screen Improves Visibility and Operability

  • Large color LCD screen is adopted for enhanced visibility.
  • Data input is performed on a minimum sequence of programming screens.
  • Programming is further simplified by the graphic display.
