PURPOSE: A numerically controlled milling machine is provided to process a peripheral surface of a workpiece in the form of an annular rod and to form a screw at the peripheral surface of a workpiece by fixing the workpiece to the numerically controlled milling machine. CONSTITUTION: A front/rear guide rail(2) is formed at both sides of a base body(1) in a length direction. A moving table(3) is installed on an upper portion of the front/rear guide rail(2). The moving table(3) is reciprocated in front and rear directions guided by the front/rear guide rail(2). A left/right guide rail is formed at both sides of the moving table(3). A moving motor(4) having a driving screw is installed at a front of the moving table. The moving table(3) is moved forward and backward driven by the moving motor(4). A moving table(7) is formed on the left/right guide rail(5). The moving table(7) is equipped with a moving motor(6) having a driving screw, so that the moving table(7) is moved in left and right directions by the moving motor(6). A clamp(11) is fixedly installed at an upper end of the moving table(7).
