20100183384 | Machine tool and cutting ring for a machine tool - The invention relates to a machine tool for use in tool machines, comprising a cutting element which is preferably configured as a cutting ring and at least two insert seats that are provided in the cutting element at distance to each other in the circumferential direction. The insert seats are fitted with at least one group of at least two identical insert tips that are detachably arranged therein and that have one working edge each, the effective working edges of the insert tips of one group being cut to the same nominal size. The insert tips are configured as indexable inserts, every single indexable insert of a group being associated with a defined insert seat in all possible positions of adjustment, and the indexable inserts of a group having at least two working edges each, one of these edges being always in the effective and at least one other edge being in the ineffective position, depending on the position of the indexable inserts in the associated insert seats. The indexable inserts of a group assume identical positions of adjustment in which defined working edges of every indexable insert of a group have the same orientation in the associated insert seat, the working edges of the indexable inserts of a group being cut to a nominal size in all common positions of adjustment. | 07-22-2010 |
20120009029 | Cutting Insert and Cutting Edge Replaceable Cutting Tool - A cutting insert includes two end surfaces each having a main surface usable as an attachment surface to a tool body, a peripheral side surface extending between the two end surfaces and a plurality of cutting edge portions each formed at an intersection between each end surface and the peripheral side surface. Each cutting edge portion includes a corner edge formed at a corner of a related end surface, a major cutting edge extending from one end of the corner edge and extending so as to depart from an intermediate plane defined to be perpendicular to the first axis and to include the second axis, and a minor cutting edge extending from the other end of the corner edge and extending in a direction to approach the intermediate plane. | 01-12-2012 |
20120082520 | TOOL HOLDER - A tool holder, used for holding a milling cutter and a grinding wheel, includes a tool bar, a tool base, a flange, a mounting shaft, and a fixing ring. The flange is formed on an end of the tool bar. The tool base is used for mounting the milling cutter. The ends of the mounting shaft are connected to the flange and the tool base respectively. The grinding wheel is mounted on the mounting shaft. The fixing ring is used for fixing the grinding wheel to the mounting shaft. | 04-05-2012 |
20120282046 | MACHINING TOOL AND METHOD OF MANUFACTURING SAME - A machining tool insert holder comprises a first surface, a second surface opposite the first surface, and a first insert tip slot extending between the first surface and the second surface, The first insert tip slot is configured to support a first insert tip. The insert holder further includes elevated projections extending from the first and second surfaces proximate the first insert tip slot. | 11-08-2012 |
20130101364 | CUTTING INSERTS HAVING DISCONTIGUOUS CLEARANCE FACES - Cutting inserts are described having at least two discontiguous clearance faces. Cutting tool systems including the cutting inserts are also described. An indexable cutting insert includes a top face, a bottom face, and at least two clearance faces connecting the top face and the bottom face at a periphery of the cutting insert. The at least two clearance faces include a primary clearance face contiguous with the top face and forming a cutting edge at an intersection of the primary clearance face and the top face, and a secondary clearance face discontiguous with the primary clearance face and separated from the primary clearance face by a bridge surface, and wherein a primary clearance angle formed by the primary clearance face is larger than a secondary clearance angle formed by the secondary clearance face. | 04-25-2013 |
20150063929 | Hard Metal Cutting Tool Holder Blade and Cutting Tool Having Such Holder Balde - A cutting tool holder blade is formed of hard metal, having a front plane, a perpendicular mid-plane. An insert pocket of the holder blade has a base jaw and a clamping jaw resiliently connected to the base jaw in a unitary one piece construction. The base jaw has a base jaw abutment surface and the clamping jaw has a clamping surface facing opposite the base jaw abutment surface, and an insert stop surface. A curved inner surface extends from the base jaw abutment surface towards and along the clamping jaw, the curved inner surface having a front extremity portion. The clamping jaw is narrowed down adjacent the front extremity portion, such that the clamping surface overhangs the front extremity portion of the curved inner surface, in a direction towards the base jaw and away from the front plane. The holder blade may be formed of cemented carbide. | 03-05-2015 |
