VIPER 500

HÖFLER Cylindrical Gear Grinding Machine


Convertible machine for individual requirements

The VIPER 500 cylindrical gear grinding machine is designed for component diameters of up to 500 mm and is optimally suited for small to medium-sized batches. To suit individual requirements, the machine is available in three different configurations: profile grinding, small grinding wheels for custom jobs and multiple-wheel technology (K) and generation grinding (W) . The special machine axis arrangement is a contributing factor to the machine's tried-and-tested precision, consistent quality and tremendous flexibility. The highly dynamic axes allow optimized 5-axis machining of wide variety of modifications in the shortest possible grinding time.

  • Convertible machine for generating, profile, and internal grinding (VIPER 500 W)
  • Retooling from generation grinding to profile grinding in less than 5 minutes (VIPER 500 W)
  • Retooling to internal grinding in less than 15 minutes
  • Highly dynamic axes at 5 m/sec2 acceleration and 20 m/min rapid traverse
  • Low-maintenance machine concept due to separation of working chamber from drive technology
  • No pump station needed for grinding oil
  • Optimal energy efficiency (e2) thanks to recovery and on-demand powering of units
