MarGear GMX 400 W Universal gear measuring center
Precision, fully automatic testing of gears and gear cutting tools up to an outer diameter of 400 mm.

Combining gear measuring tasks with various form & position features has never been easier.

With over 6000 units sold, the MarWin environment is a clear and simple way of creating complete programs in Teach In mode.
This improves programming efficiency and reduces the possibility of incorrect use.

Proven GMX realtime machine error correction is also used for positioning movements with the new MarEcon control unit, guaranteeing maximum speed and precision throughout the entire measuring and movement sequence.

Gear and form measurements are carried out on a single measuring instrument.

High precision 3D scanning sensor combined with directly driven C axis for accuracy and efficiency.
