材２３は下降する。An annular support member 22 is fixed on the fixed support cylinder 7, and a sliding member 23 is provided above the annular support member 22 so as to be slidable in the vertical direction. The sliding movement of the sliding member n is carried out while being guided along the guide surfaces 22a and 22b of the supporting member 220. These guide surfaces are sealed with the sliding member n)
(A seal is provided between the sliding member 4 and the support member 4.) An annular space 5 sealed by the seal.
is formed. When compressed air is sent into this space via the boat 28 from the compressed air supply source n, the sliding member 23#'i rises. On the other hand, the sliding member 23 is compressed 3
When the supply of compressed air into the space 25 is cut off, the sliding member 23 descends due to the force of the springs 30.

きる。Although only one air outlet 8 is shown in the illustrated embodiment, a plurality of air outlets may be provided in the circumferential direction. By doing this, it is also possible to detect the presence or absence of an inclination of the cover 7W##f of the workpiece. In addition, even if it is not possible for Fi air to be released from the air passage 35, or if the air supply is cut off when it is not needed, in the former case, there will be no dust flowing into the air passage 35 from its outlet. etc. can be prevented from entering.

得られる。As described above, in the present invention, seating is detected by blocking the air blowing from the Fi air outlet with the workpiece, so seating can be detected reliably, and
After detection is completed and before machining, the sliding member that is in contact with the spindle and is responsible for supplying air to it is automatically separated from the spindle head, so that heat and wear do not occur between the hookers. High machining accuracy and stable operation can be achieved.
