Benefits of technology

[0015]According to the present invention, in the brazing bond type diamond tool, the tip portion of the shank is thinner than the shank body. As a result, when a brazing bond layer includes diamond particles, the overall thickness of the cutting section becomes similar to the thickness of the shank body. Accordingly, the brazing bond type diamond tool may have improved cuttability through a thin cutting section.
[0016]In addition, in the brazing bond type diamond tool according to the present invention, the shank body has a thickness of at least 1.0 mm, thereby preventing the diamond tool from trembling during rotation at high speed.

Problems solved by technology

Such a diamond tool has a problem with low impact strength.
Thus, considering that the diamond tool has increased cuttability with decreasing thickness of the cutting section until it reaches a certain thickness value, the brazing bond type diamond tool does not have high cuttability.

Abstract

The present disclosure provides a brazing bond type diamond tool having excellent cuttability and a method of manufacturing the same. The diamond tool includes a shank having a body and a tip portion formed along an edge of the body, and a brazing bond layer formed on the tip portion of the shank to secure diamond particles with a brazing bond. The tip portion is thinner than the body and is integrally formed with the body.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit under 35 U.S.C. §119 of Korean Patent Application No. 10-2011-0090504 filed on Sep. 7, 2011 in the Korean Intellectual Property Office, the entirety of which disclosure is incorporated herein by reference.BACKGROUND[0002]1. Technical Field[0003]The present invention relates to a technique for manufacturing a diamond tool, and, more particularly, to a brazing bond type diamond tool which has improved cuttability through a unique shank structure, and a method of manufacturing the same.[0004]2. Description of the Related Art[0005]A general diamond tool is manufactured by welding a metal powder sintered compact having diamond particles to a shank constituting a main body of the diamond tool. The metal powder sintered compact acts as a bonding material for securing the diamond particles.[0006]Such a diamond tool has a problem with low impact strength.[0007]To solve this problem, Korean Patent Publication No. ...
