Abstract: Provided is a chemical mechanical polishing pad conditioner including a substrate including a plurality of protrusions formed on at least one surface thereof and made of ceramic or hard metal alloy. The plurality of protrusions may be formed through laser processing so as not to have angled edges on an upper end and an inclined side thereof. The chemical mechanical polishing pad conditioner further includes a diamond thin film deposited so as to cover the plurality of protrusions, wherein the diamond thin film includes a rough polishing surface on which micro protrusions having a size of several ?m are formed.

Abstract: A method of manufacturing a cutting tool is disclosed. An object of the manufacturing method of a cutting tool is to reduce contamination of an abrasive layer surface, particularly, agglomeration contamination due to slurry by improving hydrophobicity maintaining performance of an abrasive layer. A cutting tool according to the method of manufacturing comprises an abrasive layer on a base member, the abrasive layer having abrasives bonded to a surface thereof; and a coating on the surface of the abrasive layer that is a hydrophobic material film.

Abstract: Disclosed is a diamond tool. The diamond tool is coupled to a processing apparatus and may form a hole in a workpiece. The diamond tool includes a shank coupled to a connection portion formed at one end thereof and further coupled to the processing apparatus. There is a cylindrical opening formed at the other end of the shank; and segments formed at intervals along the periphery of the shank, the segments come into contact with the workpiece to form a hole in the workpiece. Each of the segments has at least one linear groove formed on the inner surface thereof or at least one oblique groove formed on the outer surface thereof. The segments are improved in shape to achieve improved cutting and cooling performance, increased stiffness and durability, and reduced load upon processing.

Abstract: The present invention relates to a diamond tool for cutting a workpiece. An object of the present invention is to provide a diamond tool, wherein diamond granules are arranged at regular intervals with respect to an outer peripheral surface of a segment so that the diamond granules are uniformly arranged in a front face of the segment, which is a substantial cutting surface, thereby improving the cutting performance thereof and simultaneously maintaining a consistent performance during the service life of the diamond tool. A diamond tool of the present invention for achieving the object has a segment that is attached to an outer peripheral surface of a shank in the form of a wheel or plate and contains diamond granules, wherein the segment comprises a plurality of diamond granules arranged on a plurality of concentric circles having the same central axis as an outer periphery of the segment.

Abstract: The present invention relates to a diamond tool for cutting a workpiece. An object of the present invention is to provide a diamond tool, wherein a wear-resistant region is formed in a connection portion between a segment and a shank of the diamond tool to prevent an under-cut phenomenon, to extend the service life of the diamond tool and to improve cutting quality due to easy discharge of cut chips. A diamond tool of the present invention for achieving the object has a cutting segment that contains a plurality of diamond granules and is attached to an outer peripheral surface of a shank, wherein the segment comprises an auxiliary cutting portion that has a thickness identical with that of the shank and a height and is attached to the shank; and a primary cutting portion that is integrally formed on the top of the auxiliary cutting portion and has a thickness larger than that of the auxiliary cutting portion.

Abstract: The present invention relates to a diamond tool for cutting a work-piece. An object of the present invention is to provide a diamond tool, wherein diamond granules are arranged at outer peripheries of segments and on certain circumferences and placed in a radial pattern from a center of a shank of the diamond tool, so that a constant cutting force is maintained even though the segments are worn out, and thus, the same cutting force is maintained during the service life of the diamond tool. A diamond tool according to the present invention for achieving the object comprises a shank in the form of a wheel or disk; segments attached to an outer peripheral surface of the shank; and a plurality of diamond granules that are attached to the segments and arranged at an outer periphery of each of the segments and on a plurality of circumferences spaced apart by a certain distance from one another and are placed in a radial pattern from the center of the shank.

Abstract: Disclosed herein is a diamond tool and a method of manufacturing the same. The diamond tool includes a shank and a segment coupled to the shank having a compact having a plurality of grooves, and diamond particles inserted into the grooves and bonded to the compact. The grooves can be formed on the compact corresponding to a desired arrangement locations of the diamond particles. A metal powder injection molding method can be employed to prepare the compacts. More than one compact can be stacked to form the segment, so that the diamond particles can be arranged in various patterns in the segment, thereby achieving simplification of the process, which allows cost savings and process automation.
