摘要： The threaded engagement device includes a female thread portion and a male thread portion, which are engaged to each other through a plurality of threads formed along the axis direction. Each thread of the female thread portion and the male thread portion of the threaded engagement device includes a crest, a root, a stab flank and a load flank. The root of the female thread portion has a straight portion extending along the axis direction and a concave rounded portion. The root of the male thread portion has a concave rounded portion, wherein the radius of curvature of the rounded portion formed in the root of the male thread portion is larger than the radius of curvature of the rounded portion formed in the root of the female thread portion.

摘要： The present invention relates to an internal groove insert. The internal groove insert comprises: a rectangular main body comprising a top surface, a lower surface, and first to fourth lateral surfaces; and first and second projections each projecting from the adjacent first and second lateral surfaces. The first projection has a first cutting edge at the side of the top surface of the main body, while the second projection has a second cutting edge at the side of the lower surface. The first and fourth lateral surfaces are inclined by an obtuse angle with respect to the top surface, while the second and third lateral surfaces are inclined by an acute angle with respect to the top surface. The central axis of the clamping hole is inclined to be parallel to the edge where the first and fourth lateral surfaces meet.

摘要： A cutting insert mountable in an insert pocket of a milling cutter and capable of effectively absorbing a radially outward force during high speed machining and high ramp machining. The cutting insert has a top surface, a bottom surface, peripheral surfaces extending between the top and bottom surfaces, a mounting hole extending through the top surface and the bottom surface, a protrusion portion protruding from the bottom surface, and a pair of lower inclined abutment surfaces formed at opposite edges of the bottom surface. The lower inclined abutment surfaces are inclined in opposite directions toward a pair of opposing peripheral surfaces, outwardly and upwardly relative to the protrusion portion. The protrusion portion extends across the mounting hole and has a lateral surface facing radially outwardly of the milling cutter. The lateral surface selectively contacts or does not contact the insert pocket depending on a revolution speed of the milling cutter.

摘要： The present invention relates to a cutting tool for machining large workpieces having relatively a large cutting amount and a cutting insert configured to be used with said cutting tool. The cutting tool comprises a cutting insert and a wedge for clamping the cutting insert. The cutting insert has a polygonal top surface, which comprises a recessed portion having a plurality of surfaces inclined toward the center of the top surface. The outline of said recessed portion is twisted at a predetermined angle with respect to the outline of the top surface. The wedge includes a projecting portion that contacts the inclined surface and pushes the cutting insert so that two side surfaces of the cutting insert can be supported by a radial inner side surface and a lateral supporting surface of an insert seat.

摘要： The present invention relates to a cutting insert having improved main cutting edges and a milling cutter provided with the same. In a cutting insert according to the present invention, main cutting edges positioned along both lengthwise edges of a front surface have a wave shape and are asymmetrical with each other, and other main cutting edges positioned along both lengthwise edges of a back surface are rota- tionally symmetrical by 180 degrees from the main cutting edges of the front surface with respect to a longitudinal central axis of the cutting insert. In a milling cutter according to the present invention, the cutting inserts are alternately mounted in pockets formed on a side surface of the milling cutter so that the concavo-convex portions of the active main cutting edges of the cutting inserts which are adjacent to each other are staggered with respect to each other.

摘要： The present invention provides a cutting insert and a cutting tool used with the same. A tool body includes at least one seating surface and a threaded hole extending as slanted with respect to the seating surface. At least one cutting insert having a mounting hole passing therethrough is removably secured on the seating surface. A screw passes through the mounting hole and is fastened to the threaded hole, thereby removably securing the cutting insert to the tool body. A wall surface of the mounting hole contacts a head of the screw about at least one first contact portion and at least one second contact portion. The first contact portion is formed at a level different from that of the second contact portion along a longitudinal axis of the mounting hole. Contact angles at the first contact portions and the second contact portions are different from each other.
