Gear profile grinding machines

The machines of the ZPI model are developed for profile grind-ing of highly precise internal gears with large modules. Especially the series production in the wind energy sector requires higher stiffness and stronger grinding power. A heavy internal grinding device was developed especially for this purpose, with the greatest emphasis on the rigidity of the grinding spindle bearing.

The measuring device is permanently integrated in the grinding head which leads to a reduction of set-up times to a minimum.
