The VIPER 500 cylindrical gear grinding machine is designed for component diameters 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 with small grinding wheels for custom jobs and multiplewheel technology (K), as well as generating grinding (W) or (KW). The VIPER 500 W / KW configuration allows both profile grinding and continuous generating grinding on the same machine – with minimal retooling 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

The machine dimensions of the standard version are for orientation only. The final machine dimension / final space requirement depends on the individual configuration of the machine.
Special machine axis arrangement guarantees high reliability in the production process
Automatic adjustment of the grinding oil nozzles ensures the same process for every grinding wheel diameter
Automatic grinding stock analysis
Adaptive process sequences thanks to variable stroke rate and dressing
Measurements taken during the production process itself (including optional correction calculation in the machine) provide quick assurance of a successful production run
Quick changeover from generating grinding to profile grinding just by swapping out the grinding wheel, grinding wheel flange, and diamond dressing roll in less than 5 minutes (VIPER 500 W)
Quick grinding wheel changes using the swivel axis, which moves the grinding wheel 180 degrees toward the operator
Tool quick-clamping system enables fast and easy tool changes (VIPER 500 W)
Short retooling times for internal grinding in less than 15 minutes
