1. A lathe comprising:
a frame including a base and a bed, with the bed mounted on a top face of the base, and with the bed extending along a rotational axis of the lathe; a carriage including a saddle and a cross sliding board, with the saddle movable on a top face of the bed relative to the frame along the rotational axis, with the cross sliding board movable on a top face of the saddle relative to the saddle in a transverse direction perpendicular to the rotational axis, with a cross feed screw received in the saddle and extending along a first rotating axis that extends in the transverse direction, with the cross feed screw rotatable relative to the saddle about the first rotating axis to drive the cross sliding board to move in the transverse direction relative to the saddle, with a driven gear mounted on and jointly rotatable with the cross feed screw, with the saddle further including a servo motor extending along a second rotating axis, with the servo motor including a driving shaft extending along the second rotating axis, with a driving gear mounted on and jointly rotatable with the driving shaft, with the driving gear rotatable about the second rotating axis to drive the driven gear to rotate, with the carriage including a controller electrically connected to the servo motor, and with the controller operable to control the servo motor to rotate or stop. |
