ROTARY CUTTER HAVING CHIP-REPELLING MECHANISM

摘要

To enable a rotary cutter (1) 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 (7) and a key (56) and a key seat (55) for receiving the key of a rotary cutter and a machine tool (10). A chip container having an outlet (9) is mounted on the peripheral area of a cutter body (2) with a bearing (8) therebetween. An arbor (5) 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 (41) of the chip container is inserted into a fitting recess (23) of a spindle head (11). A movable block ring (34) having the positioning pin is mounted on the chip container after adjusting in a peripheral direction, and is fastened with a bolt (38). 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.
