    摘要： A polygonal cutting insert for right angle machining has opposed upper and lower surfaces, a peripheral side surface interconnecting the upper and lower surfaces and having curved first and fourth side surfaces and plane second and third side surfaces, and main and secondary cutting edges alternately formed along the outer peripheries of the upper and lower surfaces. The adjacent main and secondary cutting edges form a right angle therebetween. The first side surface adjoins the main cutting edge of the upper surface. The second side surface adjoins the secondary cutting edge of the lower surface. The third side surface adjoins the secondary cutting edge of the upper surface. The fourth side surface adjoins the main cutting edge of the lower surface. The cutting insert is mounted on a milling cutter at a positive axial rake angle.

    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.

    摘要： A hexahedral insert has top and bottom faces and two pairs of opposing side faces with main cutting edges formed on the borders of the top and bottom faces to the side faces and a screw hole passing through each central portion of the top and bottom faces. The top and bottom faces are flat planes parallel to each other; each of the side faces consecutively from top to bottom includes an upper land portion, an upper inwardly-inclined portion, a flat support surface, a lower inwardly-inclined portion, and a lower land portion. Each of two adjacent side faces has a corner surface therebetween which forms corner edges on the borders to the top and bottom faces. The cutting insert enhances the cutting power by reducing cutting resistance and prevents scratches on a machined surface.
