ABSTRACT:
The disclosed embodiments are directed to an improved automatic screw machine employing a first servomotor connected to cause rotation of a first set of tooling cams independently of the operation of a spindle drive, and a second servomotor to cause rotation of a second set of cams independently of the operation of the spindle drive, wherein a multi-axis controller controls at least the speed of the spindle drive in conjunction with at least each of the two servomotors, and where the operation of at least the two servomotors is electronically synchronized.
