摘要： A cutting tip for a cutting tool used to cut or drill a brittle workpiece such as stone, brick, concrete, or asphalt and a frame saw provided with the cutting tip are disclosed. The swing type cutting tip including abrasive particles has a specific arrangement capable of enhancing the cutting efficiency of the abrasive particles, and thus achieving an enhancement in cutting performance and an increase in lifespan. The cutting tip includes a plurality of abrasive particles to cut a workpiece while swing. At least a part of the abrasive particles are arranged in the form of abrasive particle groups. Each abrasive particle group is constituted by at least two abrasive particles. At least a part of the abrasive particles of the abrasive particle groups are overlapped in a cutting direction.

摘要： 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.

摘要： A stone cutting device (110) is disclosed. A stone cutting device (110) is provided to cut a material to be cut by swinging multiple cutting tools (120) by a predetermined angle. Each cutting tool (120) comprises a blade (122) extending in the longitudinal direction of the material to be cut and at least one cutting tip (140) 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 (110) comprises a frame unit (130) provided to couple the multiple cutting tools (120), to cause the cutting tools to reciprocate, and to separately adjust tension of respective cutting tools. The frame unit (130) comprises an actuator (134) for applying tension such that a load of 8-27 tons acts on the cutting tools (120).

摘要： 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.
