Abstract:
1. A machine tool assembly comprising: a basic body having a clamping axis and an actuator movement axis, and comprising an insert holding arrangement, the actuator movement axis defining a forward engagement direction and a rearward disengagement direction; a clamp mounted to the basic body, configured to move along the clamping axis relative to the basic body, and comprising a clamp ramping surface and a clamping surface; and an actuator component mounted to the basic body and configured to move along the actuator movement axis; the actuator component comprising a rear first portion and a front second portion; the front second portion being closer than the rear first portion to the clamp ramping surface and comprising: an actuator relief surface which is outwardly slanted relative to the rearward disengagement direction to thereby form an acute internal relief angle α with the actuator movement axis; and an actuator ramping surface connected at a discontinuity to the actuator relief surface and outwardly slanted relative to the rearward disengagement direction to thereby form an acute internal ramping angle β with the actuator movement axis, the ramping angle β being smaller than the relief angle α; wherein the machine tool assembly is adjustable between: an engagement position in which the actuator ramping surface abuts the clamp ramping surface, thereby biasing the clamp's clamping surface towards the insert holding arrangement; and a disengagement position in which the actuator relief surface is located closer than the actuator ramping surface to the clamp ramping surface.
