  • METHOD OF MAKING A COATED CUTTING TOOL AND THE RESULTING TOOL
    Publication number: 20090081479
    Abstract: The present invention relates to a method of making a coated cutting tool comprising providing a substrate, depositing on said substrate a cathodic arc evaporation PVD coating of nitrides, oxides, borides, carbides, carbonitrides, carbooxynitrides, or combinations thereof wherein the coating during deposition is subjected to more than one ion etching step. Cutting tools made according to the present invention will exhibit an increased life time due to increased smoothness of the PVD coating which is due to a reduced number of surface defects.

  • Turning insert and a turning tool
    Patent number: 7488143
    Abstract: A turning tool includes an indexable turning insert with a polygonal basic shape. The turning insert includes opposite top and bottom sides, main clearance surfaces that extend between the sides and adjacent to main cutting edges, and a secondary cutting edge that is formed between each pair of main cutting edges and connects to a secondary clearance surface. Pairs of the main cutting edges approach each other in corners defining corner angles of at least 55° and at most 80°. Each of the main and secondary clearance surfaces define respective clearance angles with respect to an imaginary reference plane perpendicular to the top side, and the clearance angle of the secondary clearance surface is at least 1° greater than the clearance angle of the main clearance surface. In such a way, internal turning is provided for exceptionally small holes having diameters in the range of 12 to 6 millimeters.

  • Shingle processing tool and method
    Patent number: 7487931
    Abstract: A cutting tool for attachment to the leading area of a base is provided. The cutting tool includes a holder base having two substantially parallel cutting teeth extending from the holder base, the cutting teeth each having a cutting edge and an opening between the teeth. The cutting teeth define first and second cutting paths. The cutting teeth impact and cut asphalt shingles, and funneling surfaces of the teeth funnel the cut shingle material toward and through the opening, and into the path of the rear cutting member which cuts the material a second time. Thus, asphalt shingles are processed more efficiently, thereby creating less frictional heat and avoiding melting of the asphalt shingles.

  • Tool for chip removing machining as well as a cutting body for such tools
    Patent number: 7488142
    Abstract: A cutting tool includes a basic body and a cutting body that is fixable to the basic body via a male/female coupling. The coupling includes male-like fingers and female-like seats, which are delimited between elastically resilient projections. Each finger includes two converging wedge surfaces, which are pressable against a pair of diverging support surfaces of two adjacent projections. The axial angle of convergence of the two wedge surfaces of an individual finger differ from the angle of divergence of the two co-operating support surfaces of the projections, as long as the fingers are not loaded against the projections. In such a way, the removal of the cutting body from the basic body is facilitated.

  • Method to supply electric current to a tube furnace
    Publication number: 20090020519
    Abstract: A method of and an arrangement for transmitting electric current to a furnace that is heated, either completely or partially, by electric current conducted in the furnace wall. The current is conducted through electrically conductive devices connected to the furnace wall. At least one of the devices in proximity to the furnace wall includes a section that has a smaller cross-sectional area than the remainder of the device. The current flow through the smaller cross-section develops heat in the region of the smaller section of a magnitude that corresponds substantially to the heat magnitude that would have been conducted from the furnace wall to the electrically conductive device in the absence of the smaller cross-sectional area.
