Abstract
A chuck (10) has a chuck body (12), which is provided with three guide devices (24), on each of which is received a radially movable clamping holder (34) for fixing a workpiece to chuck body (12), the guide device (24) being constructed separately from the chuck body (12). Guide device (24) is integrally joined by a polymer concrete filling (46) to the chuck body (12) for a force transfer between guide device (24) and chuck body (12). There is no need for a particularly precise manufacture of the outer contour of guide device (24) and the recess (20) in chuck body (12), because the polymer concrete (46) is able to compensate tolerances.
Claims15
A chuck with a chuck body, said chuck body being provided with at least two guide devices, each guide device being fabricated as a separate part from said chuck body,
- wherein said chuck body has at least two recesses for receiving said guide devices, wherein each said guide device as well as each said recess extends longitudinally in a radial direction of the chuck body, each recess being at least partly filled with a hardenable filling material to fix each guide device in the chuck body,
- wherein at least one movable clamping holder is received on each said guide device for fixing a workpiece to said chuck body, wherein the moveable clamping holder has a movement direction in the radial direction of the chuck body,
- wherein the recess and the filling material for one guide device are separate from the recess and the filling material for the at least one other guide device.
