Overview

Toolink Engineering is proud to introduce the S&T Dynamics Model H80. The H80 high-speed CNC gear hobbing machine features zero-backlash, high rigidity torque motors for the table rather than the more traditional worm-drive system. Each machine has control options of Siemens 828D or Fanuc 18iMB.

  • Hob Spindle Eagle PD Drive – Enables realization of high-speed (3,000 rpm) and zero-backlash with Eagle PD Drive on hob spindle.
  • Built-in Torque Motor for Zero-Backlash – Realization of high speed (Max 450 rpm) and zero-backlash with Direct drive type Built-in Torque motor on C-axis.
  • Wet Cutting / Dry Cutting – Wet and dry hobbing processes on the same machine that satisfies a variety of customer’s requirements.
  • Ring Loader – Simple structure high-speed ring loader enables a variety of automation.
