Especially in e-mobility (e-bikes, e-scooters), transmissions are designed to be as compact as possible. Often, this translates into thin-walled workpieces that must be clamped and machined. With the required roundness tolerances in the micrometer range, radial clamping is not possible. For this reason, we have developed and designed our FLD twist finger chucks. The chucks center the workpieces very gently on the outside diameter, subsequent clamping is performed via twist fingers, and the control of the centering can even be released if required. Hence, only axial force components act on the workpiece, and excellent roundness values can be achieved.
Advantages
• Tight roundness tolerances
• Designed for high RPM
• In the main, sealed and protected by air purge
• Fast change-over of the jaws
