Easy manual actuation The TOROK manual chuck is primarily used in tool prototyping on machines without a clamping cylinder. For example, thanks to its easy manual actuation, when used on grinding machines you can safely and delicately clamp. In combination with our clamping device adaptations, such as the MANDO Adapt mandrel-in-chuck or the jaw module, many more clamping options are possible. Lightweight variant And most recent: Thanks to the optional lightweight CFRP design, with the TOROK CFK you save one-third the weight. This is particularly set-up friendly and it offloads the machine spindle bearings.
