Toolink Engineering is pleased to represent S&T Dynamics and their Model H200. The H200 CNC Gear Hobbing Machine’s high speed and high rigidity make it an ideal choice for automotive applications and similar gear cutting in a production setting. CNC controls enable automation and provide convenient operation by GUD (Global User Data) environment.

  • Built-in Torque Motor – The H200 has a built-in Torque Motor with Direct Drive System is applied to accelerate the rotation speed of the table to accomplish a high-speed and precise gear cutting process. The built-in torque motor decreases errors and backlash.
  • Semi-Dry Cutting System – The application of a Semi-dry Cutting System, which processes air cutting through the installed M.Q.L. Unit without using neat cutting oil, not only improves the roughness of the processing gear but also utilizes an environmentally friendly processing technology.
  • Fast and Precise Hob Setting – Disc Spring Clamping System, Hob Arbor Support, Hob Centering Unit
    With the application of a Disc Spring and Hob Arbor Support that utilizes a Hydraulic Quill, it is possible to perform faster Hob Setting. Moreover, it is possible to adjust the fine Hob Setting from an external machine installed at the Hob Centering Unit.
