Abstract
The invention relates to a high speed turning machine for machining a rotating workpiece to have a predetermined profile surface by using a cutting tool mounted on a pivotal tool holder that is reciprocated rapidly toward and from the workpiece surface. An armature of a linear motor is mounted on the pivotal toolholder. The toolholder is mounted in frictionless bearings. The armature is positioned on the toolholder relative to the tool and its pivot axis to provide a substantial mechanical advantage.
