Detachable, high precision and rigid connection of a tool, workpiece or gauge holder to the nose of a machine tool spindle

摘要

Interface between the spindle nose (1) and the fixture flange (11) of interchangeable tool, gauge or workpiece holder (7) of a machine tool with a shortened centring taper (8) on the underside of the flange of the holder (7), said taper being formed as an axially and radially rigid but in circumference elastically expansible tubular stub (15), which due to its elastic properties adapts itself to the diameter of the centring taper (6) on the spindle nose (1).
