Abstract
A lathe having a spindle which has a flange for the mounting of a chuck in whose base sliding weights are displaceably mounted in radial grooves and act on the bases of the chuck jaws through rocking reversing pins for the compensation of centrifugal force. To achieve a minimum overhang of the chuck, the lathe is constructed such that the chuck base and the spindle flange are made in one piece, and that the chuck body is fastened releasably on the spindle flange.
