    摘要： The invention provides a segment type diamond tool capable of improving cutting rate and reducing the amount of fine debris generated during cutting by properly arranging diamond particles in a cutting segment of the diamond tool. In the invention, the layers of diamond particles are arranged such that cutting grooves formed on a workpiece by trailing layers of diamond particles are arranged between cutting grooves formed thereon by leading layers of diamond particles, respectively, in cutting of the work piece. The cutting segment has high-concentration and low-concentration areas. The high- concentration area shows a concentration higher than an average concentration and the low concentration area shows a concentration lower than the average concentration. Also, at least one low concentration area is formed on the leading and/or trailing section of the cutting segment. The diamond tool of the invention ensures superior cutting rate and reduced amount of fine debris generated during cutting.

    摘要： A segment type diamond tool (101), used for cutting or drilling brittle substances, such as stones, bricks, concrete structures, or asphalt structures, is disclosed. In the diamond tool (101), the segments (111,112) are each set with diamonds (105) in a single-layered structure or a multi-layered structure, and are alternately or intermittently arranged on a steel core (2), different from conventional diamond tools having segments randomly set with diamonds. Such a diamond arrangement of this invention allows the diamonds (105) to more effectively perform their cutting action, and so the diamond tool (101) has an increased cutting rate, in addition to reducing the amount of fine debris generated during a cutting or drilling process to ill-affect worker's health or cause environmental pollution. In the segments (111,112) each set with diamonds (105) in the single-layered or multi-layered structure, the diamond arrangement is designed such that the diamonds (105) of each trailing segment (112) form grooves on the surface of a brittle substance along the lands between grooves previously formed on the surface of the brittle substance by the diamonds (105) of a leading segment (111).

    摘要： A diamond tool having segment type cutting tip for use in apparatus such as cutting saw machine, grinding wheel machine, and core drill machine, having a structure which cutting tip is able to produce cutting chips with relative large size during cutting operation so that produced chips are easily discharged outside to reduce the friction with cutting tip of tool, thereby to increase cutting ability and to prevent cutting chips dispersing in the air and giving rise to the bad effects to user's health and the contamination of environment. The diamond tool according to the present invention comprises a wheel body connected with a shaft of electric motor, and cutting tip for cutting, grinding or drilling crushable materials comprising a plurality of diamond layer segments disposed at predetermined intervals on the circumference of wheel body, each of diamond layer segments having at least two diamond layers longitudinally disposed parallel with the rotation direction of the tool in which diamond particles are included, and non-diamond portion disposed between the diamond layers in which diamond particles are not included.

    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.
