The key groove b 2 of the
The main shaft 2, which is transmitted to the ram 4 via the 6 and has the turning tool b fitted therein, is fixed to the ram 4 while fixing the bearing 3 in the correct position by the tapered ring bodies 8 and 8 ', so that the cutting is performed as in the conventional case. Since the main component of the force is not directly transmitted to the bearing 3 via the main shaft housing 2, the precision of the bearing 3 is not deteriorated and heavy cutting can be performed without damage.

定の加工を行うことができる。Since the present invention is constructed as described above, when the rotary tool is mounted and the hole is drilled or tapped, the taper ring body is slid and released to fix the ram and the spindle by the clamp means. After releasing, the main shaft can be rotatably mounted on the ram via the bearing as in the conventional case, and the predetermined processing can be performed on the work.

を行うことができる。When a turning tool is attached and a cutting operation is carried out, the taper ring body is slid between the taper bearing surface and the opposed taper bearing surface by the clamp means to fix the main shaft in the radial direction and to mount the bearing. Since it is possible to perform turning without damaging it, the main component of the cutting force is transmitted to the bearing via the main shaft, which deteriorates the accuracy of the bearing or damages it, as in the conventional tool mounting device for turning centers. It is possible to carry out the cutting work without reaching to.
