A Gear Collet is a special-purpose precision collet designed specifically to hold gears, splines, pinions, and toothed components during machining and grinding operations.
Unlike standard collets, gear collets are engineered to match the gear bore, face, and reference surfaces, ensuring accurate concentricity, repeatability, and distortion-free clamping.
Gear collets are essential in applications where gear accuracy, tooth alignment, and surface finish are critical.
Applications
Gear Collets are widely used in:
- Gear hobbing machines
- Gear shaping machines
- Gear grinding machines
- CNC turning & finishing of gears
- Automotive transmission gears
- Industrial gearboxes & pinions
- Spline & toothed component machining
- Mass production gear manufacturing
Key Features
- ✔ Designed as per gear bore & face geometry
- ✔ High concentricity for accurate tooth profile
- ✔ Uniform clamping without gear distortion
- ✔ Excellent repeatability for batch production
- ✔ Hardened & precision-ground clamping surfaces
- ✔ Suitable for high-speed gear machining
- ✔ Long service life with stable gripping force
- ✔ Custom designs for special gear profiles
Working Principle
The gear collet clamps the gear from the bore (ID) or outer reference surface, depending on design.
Axial actuation (manual, pneumatic, or hydraulic) causes the collet segments to grip uniformly, keeping the gear perfectly centered during cutting or grinding.
