Gear Cutting, Shaving and Shaping Tools

Gear cutting, shaving, and shaping tools are precision instruments used to manufacture high‑accuracy gears for automotive, industrial, and aerospace applications. Gear cutting typically involves hobbing or milling, where rotating cutters progressively generate the gear tooth profile under controlled feed and synchronization. Shaving is a finishing operation performed on hardened or semi‑hardened gears using a toothed shaving cutter that removes small amounts of material to improve surface finish, tooth accuracy, and noise behavior. Gear shaping uses a reciprocating pinion‑shaped cutter that gradually forms internal and external gears, especially when the geometry prevents hobbing. Tooling materials include high‑speed steel (HSS), powder‑metal HSS-E-PM, and Cemented Carbide, often enhanced with coatings like TiN, TiAlN, or AlCrN for wear and thermal resistance. Precision grinding and advanced tooth geometry design ensure high tool life and cutting performance. Applications include transmission gears, differential components, pumps, industrial gearboxes, robotics, and machinery requiring tight tolerances and optimized gear meshing.
