    摘要： A cutting tip for a cutting tool used to cut or drill a brittle workpiece such as stone, brick, concrete, or asphalt and a frame saw provided with the cutting tip are disclosed. The swing type cutting tip including abrasive particles has a specific arrangement capable of enhancing the cutting efficiency of the abrasive particles, and thus achieving an enhancement in cutting performance and an increase in lifespan. The cutting tip includes a plurality of abrasive particles to cut a workpiece while swing. At least a part of the abrasive particles are arranged in the form of abrasive particle groups. Each abrasive particle group is constituted by at least two abrasive particles. At least a part of the abrasive particles of the abrasive particle groups are overlapped in a cutting direction.

    摘要： A cutting segment for a cutting tool used for cutting or drilling a brittle workpiece, such as stone, brick, concrete and asphalt, a method of manufacturing the segment and a cutting tool provided with the segment are disclosed. The segment comprises a plurality of plate-shaped metal matrix layers laminated perpendicular to a cutting surface of the segment while being parallel to a cutting direction of the segment, the plate-shaped metal matrix layers being integrally combined with each other and made of a ferrous or non-ferrous material; and diamond particle layers arranged between the plate-shaped metal matrix layers such that diamond particles can be provided in an array on the cutting surface. The segment has an excellent cutting capability, and can be made by a simplified manufacturing process, thereby remarkably reducing manufacturing costs.

    摘要： The present invention relates to a cutting tip for a diamond tool and a diamond tool having the same which serve to cut or perforate various brittle materials such as stone, brick, concrete and asphalt. In particular, the cutting tip for a diamond tool and the diamond tool have diamond particles which are suitably arrayed to improve the cutting rate. The present invention provides a cutting tip for a diamond tool having diamond particles which are distributed in the cutting tip, wherein the diamond particles are inclined in respect to a cutting direction in a plane parallel to a cutting surface, and arrayed whereby grooved channels are formed successively overlapped on a brittle substance in cutting operation.

    摘要： The present invention relates to a core drill (10) wherein initial drilling workability is improved through reduced frictional resistance on the segment tips (30), when they are seated on the surface of an article to start cutting operation, and wherein cutting scraps or sludge produced by the segment tips (30) are smoothly discharged through the helical grooves (20b) formed on the core body (20) so as to reduce the friction between the core body (20) and the cutting scraps or sludge, whereby both the cooling and cutting performance of the core drill are improved. The invention proposes a core drill (10) with a cylindrical core body (20) with a predetermined diameter and length and with plural cutting segments (30) provided on the lower part of a core body (20) at a finite interval, wherein the cutting thickness surface of the cutting segment consists of inclined sharp thickness portion (30a) for decreased frictional resistance with an article to be processed.

    摘要： A saw blade segment with silver solder is disclosed. The silver solder of the segment facilitates substitution of the segments for abraded segments of the saw blade, thus to allow users to easily directly substitute the new segments for the abraded segments of the blade without sending the abraded saw blade to a reproduction factory and to let the users save time and cost in reproduction and reuse of the abraded saw blade. The segment also removes the typical silver solder injection device from the saw blade production factory, thus to improve the productivity of the saw blades and let the saw blade production process be automated.

    摘要： The invention provides a cutting segment for a cutting tool for cutting or drilling a brittle work piece such as stone, bricks, concrete and asphalt, and a cutting tool having the cutting segment. The cutting segment includes a cutting surface for cutting a work piece and a plurality of abrasive particle layers. The abrasive particle layers are disposed perpendicular to a cutting direction. Each of the abrasive layers has a plurality of abrasive particle rows in a width direction of the cutting segment. Each of the abrasive rows has a plurality of abrasive particles arranged in a line. Further, the abrasive layers have a plurality of blank sections therebetween. In the blanks sections, abrasive particles are absent or have a concentration of 70% or less with respect to those in the abrasive rows. In addition, the blank sections include relatively thick blank sections and relatively thin blank sections.
