  • Patent number: 9623496
    Abstract: The present invention relates to an insert for slot milling, and more specifically, to an insert for slot milling which can smoothly form a front end surface of a concave portion of a slot formed at a cutting target, and provides a safe use thereof by preventing the erroneous installation of cutting inserts coupled with insert-installation seats on both sides of a milling cutter body to prevent damage of the cutting inserts and the milling cutter. To this end, the present invention is characterized in that the plurality of cutting inserts are provided around the slot milling cutter body, one of two cutting inserts protrudes with respect to one side of the milling cutter body and the other protrudes with respect to the opposite side of the milling cutter body, and two cutting inserts are formed with different structures to prevent the erroneous installation thereof on the insert-installation seats prepared on both sides of the milling cutter body.

    Abstract: A milling insert includes a polygonal tubular insert body which has: rake faces on one polygonal surface thereof, flanks composed of circumferential surfaces adjacent to the polygonal surface, and cutting edges defining a ridge line where the rake faces and flanks intersect each other as cutting edges. The rake faces have serrations where mount portions and valley portions are arrayed alternately to intersect the cutting edges. The ridge line has a waveform shape when the flanks are viewed from above. Bottom portions and top portions of the waveform are formed into concave circular arc portions and convex circular arc portions, respectively, and are alternately repeated. Both of the concave and convex circular arc portions are a ¼ circular arc or more to a ? circular arc or less. Each of the concave circular arc portions is unevenly located between the convex circular arc portions adjacent thereto.

  • Patent number: 7740428
    Abstract: A rotor, used particularly in a rotating tool for machining workpieces, includes a rotor base body with locations, which are formed on the periphery thereof in an interspaced manner and which are suited for fitting the rotor with functional elements. The rotor base body includes a first, radially outer base body element and a second, radially inner base body element. When the rotor is not rotating, a jointing pressure prevails along an encircling joining line, which is formed between both base body elements. The second, radially inner base body element has a higher modulus of elasticity than that of the first, radially outer base body element.
