Besides the traditional applications, Cattini acquired a significant experience in manufacturing complex gears for innovative transmissions like heavy duty CVTs for high-end ag tractors, world’s first dual clutch transmission for heavy trucks, high power density solutions in compact design for large construction machinery. All proven options to increase power density are available like grinding superfinishing, isotropic finishing, shot peening and phosphating.

An in-house state-of-the-art press quenching/plug quenching heat treatment is available to minimize the inevitable distorsions on such items while excellent partners perform less critical treatments like carburizing, induction hardening and nitriding.

Almost the entire production of cylindrical gears is hard finished by the most advanced gear grinding technology while other options are under evaluation, especially for gears with insufficent gap to be finished with a grinding wheel.
