Workpiece holder for exact positioning on a clamping chuck and clamping device with a chuck and workpiece holder positioned exactly thereon

摘要

A tool holder for fitting workpieces onto a chuck has a central axial bore (3) to fit the workpiece (4) and with reference systems (8, 9) on opposite sides to fit the system either way round into the chuck. The reference systems are independently adjusted to ensure a precision fit for both orientations.
