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.

Abstract

A cutting tool for a gang saw is provided. The cutting tool of the present invention comprises: 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 comprises: 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, wherein, with respect to the left/right extending direction of the blade, the length of the metal sheet layer forming the brazing part is the same as the length of the cutting tip making contact with the brazing part, or is formed so as to be longer in the left/right direction.

Abstract

A stone cutting device configured to cut a workpiece with a plurality of cutting tools by swinging the cutting tools within a predetermined angle range. Each of the cutting tools includes: a blade extending in a length direction of the workpiece; and at least one cutting tip disposed on an end of the blade and protruding from the blade in a width direction of the blade so as to cut the workpiece while being reciprocated in a swinging motion. The stone cutting device includes a frame unit configured to combine and reciprocate the cutting tools and individually adjust tension in each of the cutting tools. The frame unit includes an actuator applying tension to the cutting tools so as to apply a load of 8 tons to 27 tons to each of the cutting tools.

Abstract

A stone cutting device is disclosed. A stone cutting device according to an aspect of the present invention is provided to cut a material to be cut by swinging multiple cutting tools by a predetermined angle. Each cutting tool comprises a blade extending in the longitudinal direction of the material to be cut and at least one cutting tip provided on an end of the blade to protrude in the width direction, the cutting tip reciprocating by means of swing movements, thereby cutting the material to be cut. The cutting device comprises a frame unit provided to couple the multiple cutting tools, to cause the cutting tools to reciprocate, and to separately adjust tension of respective cutting tools. The frame unit comprises an actuator for applying tension such that a load of 8-27 tons acts on the cutting tools.

Abstract

A cutting tool and a cutting apparatus comprising the same are disclosed. A cutting tool according to an aspect of the present invention comprises: a blade extending in the longitudinal direction of a workpiece and being adapted to reciprocate so as to cut the workpiece; at least one cutting tip provided in one end of the blade, the cutting tip being formed to be projected in the width direction of the blade such that the workpiece is cut when the cutting tip comes into contact with the workpiece; and a cutting assistance unit provided in at least one side of the blade, the cutting assistance unit being formed correspondingly to the width of the cutting tip so as to prevent an undesirable movement of the blade within a cutting space formed by the cutting tip. The cutting apparatus comprising the cutting tool comprises: a frame unit provided in both sides of the cutting direction of the workpiece; and the cutting tool provided in one side of the frame unit to be reciprocatable by power transmitted from a driving unit so as to cut the workpiece.
