ABSTRACT:
Improved chucks for supporting elongate objects having conical end portions, such as single crystal ingots of semiconductor material, while such objects are held and rotated, as in a lathe. A base portion of the chuck includes bores to accept fasteners to fasten the base to a headstock or tailstock of a lathe. The base includes a receptacle for holding an annular chuck insert which has a conical socket surface to engage the body, such as a conical end portion of a single crystal ingot, to be held and rotated. Alternatively, the base may have three or more rollers spaced equally about a central axis and rotatable about roller axes all located in a plane perpendicular to the central axis.
