PURPOSE:To increase the number of stockable tools by providing a tool storing part on the circumference of a rotary table of doughnut shape provided with a space through which a main spindle can pass at the center. CONSTITUTION:An arbitrary tool pot 2 of a rotary table 1 is located immediately below a main spindle 6 by rotating the rotary table 1 and horizontally moving a slide table 13, and the main spindle 6 is lowered to mount a tool 3. The main spindle 6 is located in the space at the center of the rotary table 1 by moving the slide table 13, and a corresponding ring 14 of the standard size is located immediately below the main spindle 6 by moving the main table. The main spindle 6 is lowered to pass through the space of the rotary table 1, and the standard size is stored by the ring 14 of the constant size, and then, the main spindle 6 is further lowered, and the tool 3 is guided by a guide ring to machine the work. Because the rotary table 1 can be freely moved, it is arbitrarily rotated to allow the free preparation of the next tool or the free change of the tool. |
