Clamp system for a tool at a machine tool spindle has an insert in the spindle drilling or base holder, with moving clamp sections which grip behind a shoulder to shorten the clamp and give balanced rotation

摘要

The clamp system for the release attachment of machine spindles (11) or base holder with the tool holder (12) or tool, especially at machine tools for metal removal, has at least two clamps (23,24) which can be spread apart. An insert is in the drilling (19) of the machine spindle or the base holder, with a clamp sections (51) which move at least partially radially outwards. When the insert is in the clamping position, the clamp sections grip behind a circular shoulder (53) in the drilling, at least partially.
