Patent number: 8864861Abstract: A cutting tool insert for machining by chip removal includes a body of polycrystalline cubic boron nitride compact (PCBN), either as a solid insert or attached to a backing body, onto which a hard and wear resistant PVD coating is deposited. The coating includes a polycrystalline nanolaminated structure of alternating A and B layers, where layer A is (Ti,Al,Me1)N and Me1 is one or more of the metal elements from group 3, 4, 5 or 6 in the periodic table, layer B is (Ti,Si,Me2)N and Me2 is one or more of the metal elements from group 3, 4, 5 or 6 in the periodic table including Al with a thickness between 0.5 and 10 ?m. The insert is particularly useful in metal cutting applications generating high temperatures, e.g., high speed machining of steels, cast irons, super alloys and hardened steels.Type: GrantFiled: May 28, 2010Date of Patent: October 21, 2014Assignee: Seco Tools ABInventors: Jon Andersson, Rachid M'Saoubi, Tommy Larsson, Mats Johansson, Per Alm

Patent number: 7758287Abstract: A negative insert for cutting machining has a top side, a clearance side perpendicular thereto and a cutting edge in a region interconnecting these sides and extending substantially in parallel with these sides. The insert has further a flat or rounded chamfer connecting the cutting edge to the clearance side on at least one lateral side of the insert in the region of a corner thereof. The chamfer makes an angle of 1°-15° with the clearance side for enabling application of the chamfer substantially tangentially to a work piece to be machined for bearing of the insert in two dimensions against the work piece during cutting machining operation carried out by the insert.Type: GrantFiled: October 12, 2007Date of Patent: July 20, 2010Assignee: Seco Tools ABInventors: Per Alm, Carlos Bueno-Martinez, Patrick Jonsson, Jan-Erik Stahl, Mats Jonsson

Patent number: 7438508Abstract: A metal cutting insert that is primarily intended for turning operations includes an upper surface, a lower surface substantially parallel with said upper surface, and at least three side surfaces extending between said upper and lower surfaces. A transition between two adjacent side surfaces forms a rounded nose radius surface at a cutting insert corner. The cutting insert includes a peripheral land bridging the upper and side surfaces at least at the corner portion at a chamfer angle. An intersection of the land and the nose radius surface forms a nose cutting edge. The nose cutting edge is defined by at least one radius. The cuffing corner includes at least one curved wiper edge. The chamfer angle in a cross-section at the nose cutting edge is larger than the chamfer angle in a cross-section a distance away from the nose cutting edge.Type: GrantFiled: February 13, 2006Date of Patent: October 21, 2008Assignee: Seco Tools ABInventors: Per Alm, Anders Wickman
