    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 cutting tools and a method for treating a surface thereof. The present invention provides a method for treating a surface of a cutting tool, the method including blasting the surface of the cutting tool using a granular abrasive and brushing the blasted surface of the cutting tool. The present invention also provides a cutting tool whose surface is treated by the method. According to the present invention, the surface condition of the cutting tool is improved, thereby achieving superior resistance to chipping while cutting a workpiece and excellent durability by means of improvement in abrasion resistance and toughness.

    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： The present invention discloses a tool assembly being capable of reducing considerably an axial length of a working member (tool), in particular, a length of a male spigot to be coupled with a coupling member and transmitting a torque to a working member without generating a loss by means of a secure coupling between a male spigot of a working member (tool) having a short length and a coupling member. A tool assembly according to the present invention comprises a tool (100) including a head (110) to be approached to a work-piece, a male spigot (120) extended from a rear end of the head (110) and a flange (150) formed at a border portion between the head (110) and the male spigot (120) and having a ring shaped flat rear surface; and a coupling member (200) consisting of a first section (210) having a cavity (211) formed on a central portion of a front side thereof for receiving the male spigot (120) and a second section (220) formed at a rear side of the first section (210) and connected to a driving means. The male spigot (120) has a tapered surface (121,122) formed on a side thereof, a through hole (212-1,212-2) communicated with the cavity (211) is formed on a side of the first section (210) of the coupling member (200), and an end of a coupling screw (412,411) coupled with the through holes (212-1,212-2) is capable of pressurizing the tapered surface (121,122) of the male spigot (120) received in the cavity (211).
