PURPOSE: To machine a part of a workpiece concealed by a main spindle, by a second spindle, by mounting the second spindle facing toward the main spindle, making the rotary shafts of both spindles parallel with each other, and holding a two axis slide system on a frame. CONSTITUTION: In the locating of a stationary slide way 18 relative to a drum 14, a spindle 23 is axially located on one of the indexing positions of a spindle 15. Whereby the spindle 23 is positioned coaxially with the spindle 15. The indexing position where the spindle 23 is coaxially located, is a retrieving position selected by the continuous movement of the drum 14. Whereby a workpiece which is passed through five retrieving positions to be machined at each position once or more, can be moved to the spindle 23. Further the spindle 23 is drawn out along the slide ways 21, 18, so that it can be axially positioned on the selected one of the tools of a turret 25, whereby an end part of the workpiece is machined. |
