--- title: "Precision Gear Machining | NN, Inc." description: "NN manufactures components used for safely connecting high voltage electrical devices commonly used in electrical vehicles and energy storage systems." canonical: "https://www.nninc.com/technologies/precision-machining/precision-gear-machining/" last_updated: "2024-08-02T21:42:25+00:00" --- # Beyond Reliable Precision Gear Machining ## The precision capabilities to meet your component requirement. Gear are a critical component in systems to mechanically transfer torque in many devices including steering systems, transmissions, and motor drives. NN Inc. has the precision manufacturing capabilities to produce many pinion, worm gears, and other gears. Our gear manufacturing technology includes gear shapers gear hobbing, and precision gear machining. NN Inc. has a gear manufacturing process that can optimally meet our customer’s gear type, tolerance, and production volume requirements. ## Gear Hobbing The gear hobbing is process uses a conical cutter. During manufacturing both the cutter and the workpiece rotates with the cutter revolving around the gear blank. This process is suitable to make spur gears, worm gears, sprockets, and pinions. | **Component sizes** - Max Hob Dia.: 110 mm - Workpiece Dia: 150 mm - Length max: 180 mm | **General Tolerances** - OD: +/- 0.01 mm - ID: +/- 0.01 mm - Angular position 0.050 mm - Concentricity 0.020 mm | | --- | --- | Hobbing is more accurate the machined gears but less accurate than grinding. It is suited for high volume lower mix production ## Gear Shaping The gear shaping is a process that uses a cutter made to the geometric profile of the gear. The reciprocating motion of the cutter and the rotation of workpiece creates the desired gear shape. Helical gears, internal gears, and spur gears can all be manufacturing using gear shaping. | **Component sizes** - Pitch Dia: 254 mm - Stroke Length: 127 mm | **General Tolerances** - OD: +/- 0.01 mm - ID: +/- 0.01 mm - Angular position 0.050 mm - Concentricity 0.020 mm | | --- | --- | Gear Shaping is more accurate the machined gears but less accurate than grinding. It is capable complex tooth profiles. It is suited for high volume lower mix production. ## Multi-Axis CNC Turning Centers NN Inc has Multi-Axis CNC Turning Center with wide ranges of capabilities making them well suited for Low volume high mix components. Machines are capable of drilling, milling, hobbing, broaching and skiving. | **Component sizes** - Diameter: 8 to 50mm - Length: 60 -170mm | **General Tolerances** - OD: +/- 0.01 mm - ID: +/- 0.01 mm - Position0.050mm | | --- | --- | Tighter tolerance can be achieved depending on datums and designs. Multi-Axis CNC Turning Machines are scalable to meet many different volume requirements economically. ## Thread Rolling Need more Information **Component sizes** - Diameter: - Length: **General Tolerances** - OD: - Roundness: - Finish: Tighter tolerance can be achieved depending on datums and designs. Ideal for high volume of larger parts. The variety of station tool also allow for components with high feature counts. ## Contact Us and See What We Can Create Together [Contact Us](https://www.nninc.com/contact/) [![NN, Inc.](https://www.nninc.com/wp-content/themes/nninc/images/logo.svg)](https://www.nninc.com/) ## NN, Inc. 6210 Ardrey Kell Rd.
