摘要： A machine tool has a cam shaft and indexing drive mechanism which is driven by a servomotor and is therefore adapted for operation within a wide range of operational parameters. An encoder mechanism provides feedback to the servo drive mechanism to effect operational control. The machine tool further comprises a variable frequency drive motor which operates the spindles of the machine tool independently of the cam shaft and indexing drive. A servo-operated threading mechanism is operable at one or more workstations of the machine tool to provide threading of parts manufactured thereby. A computer control system controls and monitors the entire operation of the machine tool.
