Abstract
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).
Claims10
Detachable, high precision and rigid connection of a tool, workpiece or gauge holder (7) with a spindle nose (1) of a machine tool spindle (3), comprising a first centring taper (6) on the spindle nose (1) and a first plane location surface (22) on the spindle nose (1), on the holder (7) a second centring taper (8) for mating with the first centring taper (6) and a second plane location surface (10) for mating with the first location surface (22), characterized in that one of the centring tapers (6, 8) is formed on a tubular stub (15, 24) and that the axial length (16) of this centring taper (6, 8) is 20% to 50% of the axial length of the tubular stub (15, 24) in such a manner that this centring taper (6, 8) is circumferentially elastic.
