Abstract: The present invention relates to a diamond tool and a method of manufacturing the same, wherein multiple abrasive layers are formed through a brazing or electroplating method, thereby improving the performance and service life of the tool. According to the method of the present invention, a plurality of concave portions are formed in a surface of the shank. A bonding paste is coated into the concave portions and abrasives are dispersed in the bonding paste to thereby form a lower abrasive layer. Again, a bonding material is coated on the lower abrasive layer and abrasives are dispersed in the bonding material to thereby form an upper abrasive layer. Then, a heat treatment is executed to fusion-bond the bonding material and abrasives onto the surface of the shank.

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 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.
