Clamp chuck for tool holder e.g. for balancing machine, has radial and axial clamping elements with at least one spring-biased support surface enclosing tool holder coupling shaft

摘要

The clamp chuck secures a tool holder (5) to a rotary machine spindle (3) via a chuck body (11) provided with a central opening (13) for reception of the coupling shaft (7) of the tool holder, acted on by radial and axial centering elements (15,17), with at least one spring-biased support surface enclosing the mantle surface of the coupling shaft and axial clamping elements (31,33).
