Abstract
To enable a rotary cutter to correspond to an automatic tool exchange apparatus by adjusting, in a peripheral direction, the position of a positioning member in response to an outlet of a chip container and a key and a key seat for receiving the key of a rotary cutter and a machine tool. A chip container having an outlet is mounted on the peripheral area of a cutter body with a bearing therebetween. An arbor of the cutter body is connected to a machine tool such that a key fits into a key seat, and at the same time a positioning pin of the chip container is inserted into a fitting recess of a spindle head. A movable block ring having the positioning pin is mounted on the chip container after adjusting in a peripheral direction, and is fastened with a bolt. Even when a key of the machine tool and a fitting recess differ in a peripheral direction, they can be adjusted. The relative position in a peripheral direction between the outlet of the chip container and the positioning pin can be adjusted.
