Gear Machining
Gear machining is used to manufacture components that transmit torque, motion, or precise synchronization in mechanical systems and power transmission assemblies. Typical applications include spur gears, pinions, splined shafts, bevel gears, worms, internal gears, and splined profiles. The most suitable manufacturing process and finishing operations are selected according to the required accuracy, gear type, production volume, and the intended function of the component.
What Can We Manufacture with This Technology?
- Typical components: spur gears, pinions, splined shafts, bevel gears, worms, internal gears, and splined hubs
- Gear types: spur, helical, bevel, internal, worm, involute splines, and other gear profiles
- Part size: from small precision gears to large transmission and machine components
- Required properties: running accuracy, torque transmission, service life, low noise, and wear resistance
- Production volumes: prototypes, small batches, and recurring serial production, depending on the component type and manufacturing process
What Types of Gears Can We Manufacture?
Depending on the application, a wide range of gear types can be manufactured on standalone gears, shafts, hubs, and other rotating components. The most suitable manufacturing process is determined by the component geometry, module, accuracy class, tooth profile, meshing requirements, and any subsequent heat treatment or gear grinding operations.
- Spur and helical gears: straight and helical gears for standard power transmission applications
- Internal gears: for hubs, ring gears, and specialized transmission components
- Bevel gears: for transmitting motion between intersecting shafts
- Worm gears: worms and worm wheels for applications requiring high gear reduction ratios
- Splines and special profiles: involute splines, custom tooth profiles, drive features, and other functional profiles
Gear Machining Capabilities
The gear machining process is selected according to the component type, required accuracy, material, heat treatment requirements, and production volume. Standard machining methods are often sufficient for simpler or lower-precision components, while high-performance transmission parts require specialized gear machining technologies and subsequent finishing operations.
- Gear hobbing: the most common process for manufacturing external spur and helical gears, as well as splines
- Gear shaping: suitable for both external and internal gears, especially where gear hobbing cannot be used
- Broaching: primarily used for internal profiles, splines, and high-volume production
- Form milling: suitable for simpler components, prototypes, and small production batches
- Power skiving: a fast and efficient process for manufacturing both internal and external gears in serial production
- Gear grinding: used to achieve high precision, low noise, and final finishing after heat treatment
- Gear shaving / gear honing / gear lapping: finishing processes used to improve surface quality, gear geometry, and running performance
- Turning and milling of gear blanks: preparation of the basic component geometry before gear cutting
- Bevel gear machining: specialized processes for manufacturing bevel gears according to the transmission design
- Worm and worm wheel machining: specialized machining processes for worm gear drives
- Gear rolling / gear forming: chipless manufacturing processes suitable for selected gear profiles and high-volume production
- Electrical discharge machining (EDM) and other specialized processes: used for specific gear profiles, tooling, and highly complex geometries
