1. A press machine for forming a part, comprising:
a linear actuator having a male-female screw arrangement and an actuator rod that is threadably coupled to the male-female screw arrangement;
a press ram that is coupled to the actuator rod of the linear actuator, the press ram for receiving a tool for engaging and forming a part;
a planetary gear system including a ring gear, a sun gear, and a plurality of planet gears located between the sun gear and the ring gear, the planetary gear system having an output shaft that provides rotational movement to the male-female screw arrangement of the linear actuator;
a first motor coupled to the planetary gear system for producing a high-speed condition on the linear actuator for advancing the press ram toward the part, the first motor coupled to the sun gear to drive the sun gear; and
a second motor coupled to the planetary gear system for producing a high-force condition on the linear actuator for forming the part with the tool on the press ram, the second motor coupled to the ring gear to drive the ring gear.
