We grind and measure cylindrical gears with outer involute straight or helical gearing with the Niles ZE 400 gear profile grinding machine.

The subsequent inspection is carried out in the KLINGELNBERG P26 gear measuring center.
 
We issue inspection reports according to DIN 3962 or ISO 1328 from the inspection machine. We can provide the complete production of gears and whole gearboxes including subsequent testing. Typical products include aircraft gearboxes, hydraulic and fuel pumps, and more.

Many years of experience
We manufacture aircraft gearboxes as separate devices and as part of our auxiliary power units and turboprop and turboshaft engines. Thanks to this, we have extensive experience with the production of gears and units.
Cooperate with us
We also offer measurement and, eventually, final product testing.
