Interface between tool holder and clamping shaft

摘要

The chuck (25) has two clamps (27) fitted on the tool holder (3), which are displaceable in opposite directions by an actuator (49), and whose clamping surfaces (65) in the area of the vertex of the clamp have a recess so that the region of the clamping surfaces at a distance from the vertex touch the inner surface (19) of a fitment pin (15) in front of the vertex of the clamp, thus guaranteeing a four-face clamping.tension.The clamps are identically and symmetrically formed and are fitted to a clamping mandrel in the recess (11) of the tool holder and extending in the assembled state of the interface (1) into the fitment pin.
