GRF-6

Finishing the tooth
surface with
high precision.

GRF-6 is developed as a machine to finish the tooth surface of planetary gear smoothly and precisely in a short cycle time. It is designed to make the structure simple and solid. High-speed rolling can contribute to cost reduction. Production capacity is four times by that of shaving machine. Rotary dies have a long life and can be used 500,000 to 1,000,000 times. The small module gear can be also finished by this machine.

FEATURES

  • Finish processing gears
    at high speed.

    Processing in as little as 10 seconds or less is also possible.

  • Minimum waste.

    To plastically process the surface of gears, minimizing chip generation.

  • The tools have an extended
    lifespan, resulting in reduced
    tool costs.

    Due to the long lifespan of the rolling dies, tool replacement is unnecessary for an extended period.
