Patent number: 9095910Abstract: A cutting insert includes a top surface, an edge surface and a cutting edge between the top and edge surfaces. The cutting edge is symmetrical about a centerline. The cutting edge has a first edge radius at a first point at the centerline of the cutting edge and a different, second edge radius at second points on opposite sides of and remote from the centerline of the cutting edge. The first edge radius is larger than the second edge radius. The top surface includes a land surface between the cutting edge and a remaining portion of the top surface. The land surface defines a surface that is distinct from the remaining portion of the top surface. A width of the land surface behind the cutting edge at the first point at the center of the cutting edge is different than the width of the land surface behind the second points.Type: GrantFiled: January 17, 2012Date of Patent: August 4, 2015Assignee: SECO TOOLS ABInventors: Daniel Wahlsten, Rachid Msaoubi, Hindrik Engstrom, Carlos Bueno-Martinez

Patent number: 8945250Abstract: A cutting tool insert for turning of hardened steels and tool steels includes a textured CVD ?-Al2O3 coated cemented carbide body. The cemented carbide body has 4.0-7.0 wt-% Co and 0.25-0.50 wt-% Cr and an S-value of 0.68-0.88 and a coercivity (Hc) of 28-38 kA/m. The ?-Al2O3 layer has a thickness ranging from 7 to 12 ?m, is composed of columnar grains having a length/width ratio from 2 to 12 and is deposited on an MTCVD Ti(C,N) layer having a thickness from 4 to 12 ?m. The alumina layer is characterised by a pronounced (006) growth texture.Type: GrantFiled: June 29, 2010Date of Patent: February 3, 2015Assignee: Seco Tools ABInventor: Hindrik Engstrom

Patent number: 8852305Abstract: A cutting tool insert for machining by chip removal includes a body of a hard alloy of cemented carbide, cermet, ceramics, cubic boron nitride based material or high speed steel, onto which a hard and wear resistant coating is deposited by physical vapor deposition. The coating includes a polycrystalline nanolaminated structure of alternating layers A and B where layer A is (Ti,Al,Me1)N and Me1 is optionally 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 optionally 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 20 ?m and method of making the same. This insert is particularly useful in metal cutting applications generating high temperatures with improved edge integrity, machining of super alloys, stainless and hardened steels.Type: GrantFiled: May 28, 2010Date of Patent: October 7, 2014Assignee: Seco Tools ABInventors: Jon Andersson, Rachid M'Saoubi, Hindrik Engstrom, Mats Johansson
