Abstract: A motor powered milling machine vice clamping actuator for use with a miffing machine vice having a rotatable shaft includes an elongated housing including an opening in a first end and a second end, a vice shaft receiving socket rotatably disposed within the housing and exposed through the opening for receiving the rotatable shaft of the vice, wherein the vice shaft receiving socket is complementary configured to frictionally engage the vice shaft of the milling machine vice. A motor operably connected to the second end of the housing which is laterally disposed to the vice shaft receiving socket having a drive mechanism which interconnects to the vice shaft receiving socket and an actuator switch operable connects to the motor for controlling direction of the drive mechanism.
