Eccentric Chucks -
Machining of Eccentric Shafts in One Clamping

Another speciality from STIEFELMAYER. Eccentricities of up to 6 m can be infinitely set with the STIEFELMAYER eccentric chuck.

Switching backwards and forwards between centric and eccentric machining can be done with a running spindle – an advantage that leads to reduced machining times for the workpiece.

Technical features:

• “on the fly” offsetting; centric – eccentric – centric machining during spindle rotation
• up to 6 mm eccentricity, fully adjustable
• mechanical lock, hydraulic actuation
• speed up to 3000 RPM
• integrated centrifugal force compensation
• for clamping diameter up to 40 mm
