Rotierendes Schneidewerkzeug

摘要

The present invention relates to a rotary cutting tool for use with at least one cutting tip (116) in which a cutter body (113) has a forward end, to the outer periphery of which the cutting tip (116) is mounted. A chip suction device (120) is arranged outwardly of an outer peripheral surface of the cutter body (113) for drawing chips generated by the cutting tip (116). The chip suction device (120) includes a generally cylindrical cover unit (122) having a wall for covering the cutter body (113). The cover unit (122) is supported by the cutter body (113) for rotation relative thereto. A chip accommodating chamber (127) is defined between an inner peripheral surface of the cover unit (122) and the outer peripheral surface of the cutter body (113). A suction port unit (123) is provided in the wall of the cover unit (122) and communicates with the chip acccommodating chamber (127). A chip guide unit is arranged at the forward end of the cutter body (113) in facing relation to the face of the cutting tip (116) for guiding the chips generated by the cutting tip (116) to the chip accommodating chamber (127).
