H 900

H 900

The machine is designed for processing of big gears, pinions, shafts, ring gears and internal gears with diameter up to 900mm and module 28mm. Rigid and stable design of main machine components provides damping of vibrations and prevents heating. Integrated mode provides even heating of workpieces thus preventing them from deformation and loosing of accuracy.

Power, precision and power-efficiency
  • Backlash drive of high-precision double worm gear
  • High quality with even acceleration and feed even at low rotary speeds of the work table
  • High power-efficiency in comparison with direct drives

For processing of parts with large modules and tooth height Modul machines with PowerCutting option are recommended. This option includes a high-capacity hob head with enlarged swivel angle.

  • High torque 1500 Nm
  • Drive with water cooling
  • Big size of mills – up to 300 mm
  • Enlarged swivel angle

PowerCutting hob head provides maximal utilisation of capacity of mills with swivelling cutting inserts. Depending on size of batch and cost of tools the parts are hobbed or form milled. PowerCutting hob head and corresponding special equipment are especially recommended for milling of parts with large modules, teeth with nonstandard height, gears with large angles of inclination, hardened or ductile materials and especially long or heavy workpieces.
