Abstract
A cutting tool includes a blade formed so as to extend in the width direction or length direction of a workpiece; at least one cutting tip formed so as to protrude from the lower portion of the blade so as to cut the workpiece by reciprocating by means of a swinging motion; and a brazing part formed between the blade and the at least one cutting tip so as to silver-braze the blade and the at least one cutting tip. The brazing part includes a first silver solder layer; a metal sheet layer formed on the first silver solder layer and having a melting point that is higher than a silver brazing process temperature; and a second silver solder layer formed on the metal sheet layer.
Claims7
A cutting tool for a gang saw, comprising:
- a blade configured to extend in a width direction or a length direction of a workpiece;
- at least one cutting tip protruding from a lower portion of the blade and configured to cut the workpiece while reciprocating in a swinging motion;
- and
- a joint portion disposed between the blade and the at least one cutting tip and configured to bond the blade and the at least one cutting tip by a brazing,
- wherein the joint portion includes a first brazing layer, a metal sheet layer disposed on the first brazing layer and having a melting point higher than a temperature of a brazing bonding process, and a second brazing layer disposed on the metal sheet layer, and
- based on a direction in which the blade extends laterally, a length of the metal sheet layer constituting the joint portion is equal to, or greater in a lateral direction, than a length of the cutting tip bonded to the joint portion.
