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.

Disclosed herein is a diamond tool for cutting a workpiece and a method of manufacturing the same. The diamond tool includes a shank and a segment coupled to the shank. The segment includes a tape having a plurality of inserting sections formed on a surface of the tape, and diamond particles inserted into the inserting sections and bonded to the tape by pressure sintering. The inserting sections are formed in the tape corresponding to desired arrangement locations of the diamond particles. The diamond particles can be arranged in various patterns in the segment, thereby achieving simplification of the process, which allows process automation and reduces manufacturing costs.

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 μm are formed.

Disclosed is a diamond tool having a metal plate inserted therein. Between abrasive layers containing diamond particles is inserted a ferrous or non-ferrous metal plate having a wear resistance lower than that of the abrasive layers such that a concave groove is spontaneously formed during a cutting process, thereby reducing the contact load with a workpiece to thereby avoid vibration (wobbling) of a shank, and providing a discharge path for smoothly removing cutting chips and the cooling water. In addition, the content of abrasives and the wear resistance of bonding material are uniformly constituted so that the shrinkage rate does not need to be considered during sintering and the manufacturing process can be simplified, thereby reducing the manufacturing cost and improving the productivity therefor. Furthermore, the area of the metal plate can be controlled, thereby enabling an easy design conforming to the working conditions with a workpiece.

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.
