PURPOSE:To simplify a work, by automatically attach-detaching and indexing an attachment to a spindle head of the machine tool with a rotary cutting tool used like plano miller. CONSTITUTION:With a solenoid valve 32 operated and pressurized oil fed from an oil supply part 14, a piston 16, engaged to a sloove 31, is shifted, and this causes a pull stud 11 to be pulled into a spindle head 1, and the attachment state of an attachment A to the spindle head 1 can be maintained by a holding of the pressurized oil. In a condition with an input shaft 6 coupled to a main spindle 4, when fed the pressurized oil from an oil supply port 15, the pull stud 11 is pushed out from within the spindle head 1, and the attachment is released. An indexing is operated in accordance with the order, such as release of an attaching of the attachment A, 90 deg. turning to the assigned position, and reattaching. |
