  • Publication number: 20090301274
    Abstract: A device for cutting bar-shaped or tubular workpieces (1, 27), for example a peeling machine, is presented, in which, for the first time, the advance of the tools (7, 26, 44, 46) is brought about by a relative rotation between a toolholder (3, 25, 45) carrying the tools (7, 26, 44, 46) and an advancing sleeve (4, 24, 47). The toolholder (3, 25, 45) and advancing sleeve (4, 24, 47) are driven via gearwheels (19, 18) arranged on the same gear shaft (17) and having an oppositely oriented helical toothing. By means of an axial movement of the gear shaft (17), a relative rotation between the toolholder (3, 25, 45) and advancing sleeve (4, 24, 47) is achieved on account of the helical toothing. Moreover, it is proposed to use milling cutters (26, 44) as tools.

  • Patent number: 7410330
    Abstract: The cutter assembly contains an axle having a number of parallel, equally spaced troughs along the axial direction, and a number of circular blade discs, each having a center hole threaded through by the axle. Each blade disc has a number of teeth along the circumference of the center hole corresponding and matching to the troughs of the axle. The blade disc has fewer blades than the teeth and the blade discs therefore can be mounted on the axle in different orientations so that their blades are spirally arranged. The axle of the cutter assembly has a fixed end and the blade discs can be sequentially installed to or removed from the other free end. The bearing at the free end has a smaller diameter so that the blade discs can be removed or installed directly passing through the bearing without removing it first.

  • Patent number: 6520722
    Abstract: Disclosed is a cutting tool with an asymmetric tooth form, and a method for making the same. Such tooth forms are useful for cutting tools such as band saw blades, circular saws, hacksaws and other saw type products. The tooth form of this invention can improve precision over prior art tooth forms by reducing manufacturing variability. The improved precision provides more consistent performance and a better quality of the cut surface. The non-symmetrical form ground tooth profiles cut designated chip profiles and thereby cut specific portions of the kerf much like a broaching application. This non-symmetrical ground tooth profile can alter the distribution of the downfeed cutting force allowing for more aggressive cutting or conversely, cutting at the desired rate with less downfeed pressure.

    Abstract: A cutting tool for high-speed machining has at least one cutting insert that is interchangeably mounted to a main body of the tool. At least parts of the supporting surface of the cutting insert and of the receiving surface of the main body of the tool, when viewed in cross section perpendicular to the axis of rotation, are of an approximately V-shaped configuration and are engaged with each other. The crown region and also at least one of the end regions of the V-shaped supporting surface and receiving surface are mutually relieved. A bearing surface on the main body of the tool, in order to radially support the cutting insert, is arranged in such a way that a mounted cutting insert is tilted such that the supporting surface of the main body and the receiving surface come into mutual contact at only two points.

  • Patent number: 6217262
    Abstract: This invention relates to a high speed milling tool for deburring or edge radiusing of machine parts. This tool comprises a plurality of cutter inserts having corresponding edges whereby each edge mills only a portion of the machine part radius. This requires a full revolution of the tool producing a faceted approximation of the cut radius to make a complete cut. The tool offers significant improvement in part feedrate in high speed milling applications requiring either a longer tool reach or set length or parts having taller or thinner edges without effects of deflection or chatter between the part and tool.
