PURPOSE:To aim at the promotion of labor-saving and efficiency, by making the machining of multisurfaces of a work performable simultaneously or continuously. CONSTITUTION:A rotary table 4 is indexibly installed in an index table 2, while an index shaft is inserted coaxially through inside the table 4, and plural index tables 10 are rotatably set up in the rotary table 4 at equal angles. And, each of these tables 10 and index shafts are coupled together at each commensurate position via an index mechanism having the same indexing angle. Therefore, when a drill unit C exists in the central position in its machining range D, drilling to a tip end face W1 of a work W comes possible to be done. When the drill unit C is situated in an ascending position, machining to four sides W2-W5 of the work W can be performed. At the same time, even at the descending position of the unit C, machining to four sides W6-W9 can be done. Therefore, machining for nine sides in total to one work comes possible to be done. In addition, machining for multisurfaces is thus possible simultaneously or continuously. |
