    • A segment type diamond tool has diamond particles appropriately distributed on segments of the diamond tool, thereby providing an excellent cutting rate and reducing fine debris generated during a cutting operation. The diamond tool comprises a plurality of segments, each of the segments having a single plate-shaped layer or a plurality of plate-shaped layers of diamond particles arranged thereon, and the layers of diamond particles being arranged on the segment such that cutting grooves formed on a workpiece by a trailing layer of diamond particles are arranged between cutting grooves formed thereon by a leading layer of diamond particles, respectively, during a cutting operation on the workpiece, wherein the diamond particles are arranged at a predetermined tilt angle to a line connecting upper vertices or a line connecting lower vertices of a cross section, cut parallel in a cutting direction and perpendicular to a cutting surface, so that the diamond particles are protruded and uniformly spaced from each other on the cutting surface of the segment during the cutting operation on the workpiece.

    • The present invention relates to a method for cutting or drilling a brittle workpiece including stones such as marble and granite, brick, concrete and asphalt, using a frame gang saw, and has as its objective a reduction in the initial cutting time of the workpiece, so that productivity may be markedly enhanced, and also to minimize deformation of the blade so that product quality and the lifetime of the frame gang saw blade may be enhanced. The key points of the invention are a workpiece for a frame gang saw wherein the workpiece is cut by a frame gang saw comprising one or more blades furnished with a plurality of cutting tips or a blade not furnished with a cutting tip, and on the workpiece are formed one or multiple grooves into at least a part of at least one cutting tip out of the cutting tips or at least a part of the blade not furnished with a cutting tip is inserted; a method for cutting the workpiece by using a frame gang saw; and a product that has been cut by the cutting method. According to the invention, not only can productivity be markedly enhanced but also the deformation of the blade can be minimized so that product quality and the lifetime of the frame gang saw are enhanced by providing a workpiece with grooves formed thereon.

    • 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.
    • 本发明提供一种段式金刚石工具,其能够通过在金刚石工具的切割部分中适当地布置金刚石颗粒来提高切割速率并减少在切割期间产生的细碎屑的量。 在本发明中,金刚石颗粒层被布置成使得在切割工件时分别通过金刚石颗粒的引导层分别在其上形成有金刚石颗粒的后续层的工件上形成的切割槽布置在其上形成的切割槽之间。 切割段具有高浓度和低浓度区域。 高浓度区域的浓度高于平均浓度,低浓度区域的浓度低于平均浓度。 此外,在切割段的前部和/或后部形成至少一个低浓度区域。 本发明的金刚石工具确保切割时产生的切割速度和精细碎屑的数量减少。
