摘要:
A tangential reversible cutting blade, comprising: a prismatic body which is bordered by two opposed, identically shaped first surfaces and four identically shaped, interposed lateral surfaces, four equal-length main cutting edges on each of the first surface which are defined with one lateral face each, a raised web on each lateral surface with the four webs being symmetrical with a central plane through the lateral surfaces, a through mounting bore coaxial with the axis through the centres of the first surfaces, metal-cutting faces on the lateral surfaces which are defined by fillets adjacent to the main cutting edges on either side of the associated web, and cutting-tool flanks on the first surfaces which are defined by a spherical surface shape of the first surfaces adjacent to the main cutting edges.
摘要:
A face milling cutter or angular milling cutter, with a carrier body which on its periphery at regularly or irregularly distributed distances comprises pockets which extend parallel to the rotational axis of the carrier body for accommodating cassettes which for their part comprise seating surfaces for receiving cutting plates, with a fastening device for the cutting plates in the cassette, with a screw fastening for fixing the cassettes in the pockets and with adjusting screws for a limited axial adjustment of the cassettes in the pockets, wherein the adjusting screws are seated in threaded bores of the carrier body, which proceeding from the end-face of the carrier body are arranged approximately parallel to the rotational axis of the carrier body.
摘要:
Method for making a form-fitting connection between a tool insert and a tool holder of a rotatingly driven tool, wherein the tool holder has bearing surfaces by which forces or torques are transmitted to the tool insert, wherein the tool insert is made from a material harder than that of the tool holder and by sintering a green compact of powder. A sintered green compact for the tool insert is used as a hob, by which the bearing surfaces in tool holders are manufactured by punching or press-forming.
