  • REDUCED VOLUME CUTTING TIP AND CUTTER BIT ASSEMBLY INCORPORATING SAME
    Publication number: 20090051212
    Abstract: A cutting bit includes a body having a head and a shank, a cutting tip attached to a front surface of the head, the cutting tip including a base portion, an upper portion and a tip portion, and a cavity extending into an interior of the cutting tip a distance from a bottom surface of the base portion. The distance the cavity extends into the interior is such that a bottom of the cavity is axially closer to the tip portion than at least a portion of a skirt separating the base portion and the upper portion. The cutting tip is attached by both a mechanical connection and a joining process. An example of a mechanical connection is a post on the front surface of the head of the body inserted into the cavity of the cutting tip. A cutting tip per se, a cutting bit on a mining machine and a method of manufacturing of a cutting bit are also disclosed.

  • Punch for cold forming operations
    Patent number: 7490502
    Abstract: A cemented carbide tool containing tungsten carbide, titanium carbide, niobium carbide, possibly TaC, cobalt, chromium and possibly nickel, iron, molybdenum is disclosed. The composition of the materials provides a lighter material than usual, combined with a good resistance to corrosion as well as high hardness and wear resistance. These properties are particularly interesting for the manufacture of punch tools for cold forming operations. Cold forming tools made with these materials will have much better performance, particularly more steady performance and much longer lifetime. A method of cold forming and drawing, particularly deep drawing and ironing process of aluminum and steel beverage can manufacturing, is also disclosed.

  • 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.
