となっている。FIG. 4 is a schematic view showing the structure of a band saw cutting blade, and FIG. 5 is an enlarged view of the blade portion. The band saw cutting blade 1 has a thin endless belt base metal 2 with diamond, CBN abrasive grains or the like on one end surface thereof. It has a structure in which the ultra-hard abrasive grains 3 are bonded by the metal plating layer 4.

ック等の被加工物６を切断する。FIG. 3 is an explanatory view of a state in which a work piece is cut by a band saw cutting blade. The band saw cutting blade 1 is wound around a pulley 5 of a cutting machine, and is continuously rotated at a high speed while being coated with the above-mentioned ceramic or the like. The workpiece 6 is cut.

多い。However, when the band saw cutting blade is rotated by the pulley to cut the workpiece, stress is repeatedly applied to the endless belt base metal. The repeated stress is applied by bending stress on the pulley surface of the cutting machine, tensile stress due to tension between the pulleys, and vibration of the cutting machine. Therefore, the endless belt base metal often breaks even though the diamond, CBN, and the abrasive grain layer remain sufficiently on the endless belt base metal.

考えられる。FIG. 2 is a state diagram of the endless belt base metal after breaking, and when observing the band saw cutting blade after breaking, as shown in FIG. 2, the endless belt base on the opposite side to the electrodeposition portion 4 without the electrodeposition portion 4 is present. A large number of cracks 8 are generated on the back surface 7 of gold due to metal fatigue, and it is considered that these cracks grow and lead to fracture.

鋸切断刃を提供するものである。Therefore, the present invention provides a band saw cutting blade that has a long life and is unlikely to break even if stress is repeatedly applied to the endless belt base metal.

エンドレスベルト台金の砥粒電着側の背面側に砥粒電着

特徴とするものである。According to the present invention, a metal layer is formed on the back surface side of the endless belt base metal of the band saw cutting blade on the abrasive grain electrodeposition side to cause the same degree of elongation as the abrasive grain electrodeposition side. It is characterized by.

ける。When the electrodeposition portion is provided on one side of the endless belt base metal, the extension on the electrodeposition portion side is suppressed,
When there is a difference in elongation between the electrodeposition side and its back side and repeated stress is applied to the endless belt base metal, cracks occur due to metal fatigue, which is thought to grow and easily break. . This means that when a continuous rotation test of the endless belt base metal was carried out with or without the electrodeposited portion, it broke after 5 hours of continuous rotation with the electrodeposited portion, but 30 hours or more of continuous rotation without the electrodeposited portion. However, no cracks were found and no breaks were observed, so I nod.
【００１０】そこで、本発明は、電着部側と背面側との
伸びが同程度になるように、背面側に金属層を設ける。Therefore, according to the present invention, a metal layer is provided on the back side so that the electrodeposited side and the back side have substantially the same elongation.

めっきによって電着することにより得られる。BEST MODE FOR CARRYING OUT THE INVENTION The band saw cutting blade is manufactured by a known method. For the endless belt base metal, a metal having high fatigue strength and rigidity such as spring steel is used. It can be obtained by attaching abrasive grains such as diamond and electrodepositing them by metal plating.

In this case, a ceramic layer such as alumina or a metal layer on which glass powder or the like is electrodeposited may be used. Furthermore, the metal layer can be formed by a coating method other than plating, such as thermal spraying.
