    Abstract: A machine tool assembly includes a basic body, and a clamp and an actuator component mounted to the basic body. The clamp and actuator components include ramping surfaces for cooperatively biasing the clamp into an engagement position. The actuator component is configured to move along an actuator movement axis and includes an actuator relief surface connected, and extending at a different angle, to the actuator component's ramping surface. The different angle is configured to facilitate disengagement of the actuator component and clamp for a smaller movement of the actuator component along the actuator movement axis than would have been the case in the absence of such configuration, thereby allowing a compact construction of the assembly.
