Internal cylindrical grinding machine ZPI

for gearsfor large workpiecesCNC

Product description
The ZPI series is a profile grinding machine designed for the grinding of highly precise internal gears with large modules. It is engineered for series production demands such as those in the wind energy sector, where increased stiffness and grinding power are required. A heavy internal grinding unit with reinforced grinding spindle bearing ensures process stability. The measuring device is permanently integrated in the grinding head to minimize set-up times and support repeatable production.

Key features

• Profile grinding of internal gears
• Wobble compensation for concentricity control
• Grinding head with double-spindle dresser
