    • 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.

    • 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.
    • 分段式金刚石刀具具有适当地分布在金刚石刀具的区段上的金刚石颗粒,由此提供优异的切削速率并且减少在切削操作期间产生的微小碎屑。 该金刚石工具包括多个节段,每个节段具有布置在其上的单个板状层或多个金刚石粒子的板状层,并且金刚石粒子层布置在节段上,使得形成切割槽 在工件上的切割操作期间,通过金刚石颗粒的后层在工件上分别布置由金刚石颗粒的引导层形成在其上的切割凹槽,其中金刚石颗粒相对于连接线 上部顶点或连接横截面的下部顶点的线,在切割方向上平行地切割并且垂直于切割表面,使得在切割操作期间金刚石颗粒在片段的切割表面上彼此突出且均匀地间隔开 在工件上。

    • There are provided a tool, a grinding cup tool, a core bit and a propeller used in the grinding cup tool, all of which are used to cut, drill, planarize and grind a brittle workpiece such as stone, brick, concrete, asphalt and the like, and by themselves are able to collect dusts which are generated during the processes. The tool, the grinding cup tool, the core bit and the propeller used in the grinding cup tool, all of which include a core having tips fixed therein, each tip having abrasive particles distributed thereon; and a driving machine for driving the core, include a propeller having at least two wings, the wings being positioned above the tips and rotating with the core to guide dusts, which are generated during the processes, upwards. The tools may be useful to significantly reduce the generation of scattering dusts (particles) without the use of a separate dust-collecting apparatus since they by themselves are able to collect dusts which are generated during the dry process, and to easily collect generated dusts in one collection place and discard the collected dusts, and to improve the machinability of products by removing fine dusts generated during a cutting process.
    • 在磨杯工具中提供了一个工具,磨杯工具,芯钻头和螺旋桨,所有这些工具都用于切割,钻孔,平面化和磨削脆性工件,如石头,砖,混凝土,沥青和 并且本身能够收集在该过程中产生的灰尘。 研磨杯工具中使用的工具,磨杯工具,芯钻头和螺旋桨,所有这些工具都包括其中固定有尖端的芯,每个尖端具有分布在其上的磨料颗粒; 以及用于驱动所述芯的驱动机构,包括具有至少两个翼部的螺旋桨,所述翼部位于所述尖端之上并且与所述芯一起旋转以引导在所述过程期间产生的灰尘。 这些工具可以用于显着减少散射灰尘(颗粒)的产生而不使用单独的集尘装置,因为它们本身能够收集在干燥过程中产生的灰尘,并且容易地收集生成的粉尘 一个收集场所,丢弃收集的灰尘,并通过去除切割过程中产生的细小灰尘来提高产品的机械加工性。
