ABSTRACT:
A chip adhesion preventing device is capable of preventing chips from adhering to the drill shank of a drill held on a spindle (1) included in a boring machine. Fluid passages (17, 23) are formed in the spindle (1) and a work holding member (19), respectively, and nozzle holes (18 and 22) are formed in the spindle (1) and the work holding member (19) so as to be connected to the outlet ends of the fluid passages (17 and 23), respectively, and to be directed toward the shank (13) of the drill (3). A high-pressure fluid is jetted through the nozzle holes (18, 22) toward the drill shank (13) to blow off chips (15) adhering to the drill shank (13).
