  • Milling tool with rotatable cutting disks
    Patent number: 9862039
    Abstract: A milling tool having multiple cutting disks is disclosed. Each cutting disk is anchored into a flute on the milling tool with clamping screws. During use, the cutting disks naturally become dull. In a preferred embodiment, a single clamping screw is used to hold the cutting disk in place. The clamping screw is loosened and the cutting disk is rotated such that a new and sharp portion of the cutting disk is exposed for use. In an alternative embodiment, multiple clamping screws are used to secure the cutting disk into the flute. In the event a cutting disk becomes stuck in a flute, a clamping screw in a threaded bore coaxially aligned with the locating bore is used to push the cutting disk and eject it out of the flute. This design allows for many positions on the cutting disk to be used before the disk needs to be replaced, sharpened, or refurbished.

  • Rotary cutting tool with unequal indexing, alternating helix angle and varying helix angle along length of cut
    Patent number: 9862038
    Abstract: A rotary cutting tool with a longitudinal axis includes a shank portion and a cutting portion defining a length of cut. The cutting portion includes a plurality of blades separated by flutes extending along the length of cut. A first blade forms a first helix angle with respect to the longitudinal axis at the cutting tip. A second blade adjacent the first blade forms a second, different helix angle with respect to the longitudinal axis at the cutting tip. The cutting edge of the first blade is formed at a first distance with respect to the cutting edge of the second blade. A helix angle of at least one of the plurality of blades varies along the length of cut and a distance between cutting edges of the first and second blades varies along the length of cut.

  • Tool for chip removing machining and an insert-holding blade as well as a key therefor
    Patent number: 9855609
    Abstract: A parting tool is in the form of a blade and a replaceable cutting insert, as well as, a key having an eccentric body. The cutting insert may be clamped in a seat under an elastic, resilient clamping finger. In the blade, a keyhole is formed, into which the eccentric body can be inserted. In the keyhole, there are included concave sliding surfaces, which border on a flat stop surface. With these, convex corner surfaces and flat shoulder surfaces on the eccentric body can interact. By the unique design of the keyhole and eccentric body, a gentle interaction between the surfaces is obtained, which guarantees a long service life of the blade, as well as the key.

  • Hollow rotating shaft finishing method and hollow rotating shaft
    Patent number: 9855606
    Abstract: In the process of cutting the outer circumference 10o of a hollow rotating shaft 10 by using a finishing turning tool 36, the position of the finishing turning tool 36 is adjusted in the direction orthogonal to the virtual reference shaft center VS so that the center position CPo of the outer circumference 10o of the hollow rotating shaft 10 is deviated from the virtual reference shaft center VS in the same direction as the direction of the deviation vector ?Di by an amount corresponding to the magnitude |?Di| of the deviation vector ?Di. This can reduce the unbalance to zero also in the middle of the shaft and sufficiently reduce runout of the hollow rotating shaft 10 even if the rotation speed of the hollow rotating shaft 10 increases. Accordingly, it is possible to further improve the reliability of the hollow rotating shaft 10 at high rotation speed.
