<p>A cutting tool for use on a machine tool, such as a face milling cutter, has a rotationally-driven tool body (11) and a plurality of cutting tips (13) mounted on the tool body. The cutting tool has a chip receiver (22) surrounding and encasing the cutting edges (13a) of the cutting tips carried by the rotational tool body, for receiving chips of metal generated as a result of the machining. The chip receiver has a chip discharge opening which may be connected to a vacuum suction means for promoting the discharge of the chips. A cutting medium in the form of a mist (m) of a cutting oil or chilled air is supplied to a region (R) near the cutting edges and the surface of a workpiece (w) which is being machined, via cutting medium discharge bores (26) and openings (26a) provided in the end extremity of the chip receiver or in the tool body. A colorant is mixed with the mist of the cutting oil, or light rays are applied to the mist, to visualize the mist of the cutting oil, thereby enabling adjustment to ensure that the cutting oil mist is correctly and stably directed to the target region. <IMAGE></p> |
