Abstract

A system for performing machining operations on different portions of workpieces comprising a plurality of workstations including a lathe disposed along a predetermined path, in the present instance, a circular path. A turntable supports a plurality of workpiece chucking devices equi-spaced circumferentially around the turntable. The turntable rotates relative to the workstations to position a workpiece chucking device at each workstation permitting different machining operations to be performed on workpieces simultaneously. The chucking devices are moveable on the turntable in a radial direction to present the workpieces to the various tools at the workstations. The workpiece chucking devices include spindle motors and means for synchronizing the speeds of the spindle motors of the chucking devices with the lathe motor.
