Abstract:
A method and apparatus for a power feed drill. The power feed drill comprises a servo motor, a roller screw, a ball spline shaft, an air motor, and a collet chuck. The roller screw is rotatably mounted to the servo motor. The ball spline shaft has a first end connected to the roller screw, wherein rotation of the roller screw in a first direction moves the ball spline shaft in the first direction and wherein rotation of the roller screw in a second direction moves the ball spline shaft in an opposite direction to the first direction along an axis. The air motor is capable of transmitting rotation motion to the ball spline shaft to rotate around the axis. The collet chuck is fixably attached to a second end of the ball spline shaft, wherein the collet chuck is adapted to receive a tool.
