CNC AXES
  • High-speed direct-drive hob head with CNC shifting
    • Automatic retraction of X-axis during power failure, preventing hob damage
  • Direct drive torque motor for the work spindle
    • Driven via FANUC® spindle motor with rotary encoder for accuracy
  • Flexible standard dialogue program offering:
    • One or two gears on a single workpiece
    • Radial, axial, climb, and/or conventional hobbing on single- or two-cut cycle
    • Crowning (lead modification) and deburring using two equal hobs
    • Automatic shifting over broken hob section
  • CNC by FANUC® 0i-MF with 7 axes (optional 8 with gantry automation)
    • Tangential position of hob head (shifting) by CNC
  • Miter gear (straight bevel gear) cutting for:
    • Index milling
    • Conikron generating for modules ≤ 0.5 mn, 50.8 DP
  • Precision, repeatability, and control with linear scale on the X-axis
  • Cast iron machine base for optimum stability and dampening
    • Slant bed design concept for optimal chip removal
  • Optional re-hobbing (skiving)

Bolstering your quality and productivity.

The Hera 90 CNC gear hobbing machine combines advanced technology, precision components, and economic pricing to enable profitable production of high quality spur gears, helical gears, straight bevel gears, worms, and other hobbed profiles.
