Abstract
A method and apparatus are used for automatically cutting workpieces on a portable lathe. By using the method and apparatus, the machining processes including charging the workpieces into a chuck, holding the workpieces on the chuck, cutting the workpieces with a cutting tool, loosening the workpieces from the chuck, and discharging the workpieces from the chuck are automatically performed under a timing control of a timer. In the method, the workpieces are charged into and discharged from the chuck by blowing the compressed air of a pair of air nozzles respectively onto the opposite ends of the workpieces. The operation of the chuck is controlled by a hydraulic clutch drivable by a hydraulic cylinder.
