Cut metal gear
CMR Group
Production of custom reducing gears.
Main features
The materials used to manufactures the gears are, in order of importance:
steel, cast iron, bronze and at times light alloys (for toothing with a low level of stress).
Steel gears can be manufactured with hardened and tempered materials (140-400 Brinell) which are processed without altering the level of final hardness, or with case-hardened toothing, processed before the thermal treatment, including those to be subjected to induction hardening.
Case-hardened gears are suitable for heavy work applications where the materials used are nickel, nickel–chrome, and nickel-chrome-molybdenum alloy steels as they are subject to distortion.
