Abstract

PURPOSE:To enable a band saw to highly accurately and efficiently cut an expensive hard material with no wastefulness, by providing abrasive grains of diamond or cubic crystal boron nitride or a sintered material containing these abrasive grains in one side end part of an endless steel belt formed by rolling a seamless steel pipe. CONSTITUTION:A steel pipe 1 with no seam at all, being rolled, forms an endless steel belt 2 being used as a base metal of endless band saw decreasing the thickness. The endless steel belt 2, electrodepositing in its one side end part a diamond dust 3 to provide an edge part 4, forms notched parts in an equal space. The steel belt, using abrasive grains of cubic crystal boron nitride in place of the diamond dust 3, binds the abrasive grains to be attached by electroplating or electroless plating. Or a metallic dust sintered material or a resin powder sintered material, containing the abrasive grains of the diamond dust 3 or the cubic crystal boron nitride, is welded or brazed or adhesively attached. In this way, the endless band saw, having no seam at all with a uniform quality as a whole in larger strength further with a fine thickness of 0.5mm or less, can be easily manufactured.

ものである。[Detailed Description of the Invention] (Field of Industrial Application) This invention is for cutting or cutting hard materials such as glass, ceramics, silicon, ferrite, crystal, quartz, carbon, cemented carbide, etc. This relates to an endless band saw.

At the same time, it is necessary to process it precisely.

質物切断用無端状帯鋸がある。Conventionally, as shown in Fig. 3, an annular endless steel strip (B) is formed by welding or brazing both ends of a thin steel strip made of high-strength hardened steel.
8) There is an endless band saw for cutting hard materials, in which diamond or cubic nitride abrasive grains (not shown) are bonded to the negative end portion by electroplating or the like to form a blade portion.

があった。(Problems to be Solved by the Invention) Although such prior art can meet the above-mentioned requirements to some extent, the structure always has connections, and due to distortion of the connections, etc. The accuracy is poor, and the wall thickness of the endless steel strip (8) needs to be 0.5 mm or more.
There was a problem in that it was impossible to manufacture ultra-thin endless bandsaws with a diameter of less than 5 cranes.

分速１０００メートル以上で走行するために、その鋼帯

向にそりがでてくる。In other words, the precision of an endless band saw is greatly related not only to the cutting edge made of diamond or the like, but also to the precision and strength of the steel strip that is its alloy. Because the steel strips are under strong tension from the pulleys and run at speeds of over 1,000 meters per minute, the steel strips are exposed to harsh conditions and become fatigued, causing distortion and warping in the width direction.

クランクや破断さえも発生するので、少なくとも鋼帯の
肉厚は０．５鶴以上必要であり、容易に薄（精度の良い
無端状の帯鋸が製作できないという問題があった。In particular, welded joints are affected by heat from the beginning, so they are different and weak from other parts, and are susceptible to not only distortion and warping but also cranking and breaking, so at least the thickness of the steel strip is 0.5 crane or more is required, and there was a problem that a thin (accurate) endless band saw could not be manufactured easily.

きないものである。In addition, as a connection method for such joints, a welding method that locally heats with an electron beam or laser has been developed, and although improvements have been made such as reducing the area affected by heat, hardened steel types are less likely to contain carbon. There are problems such as segregation making it extremely brittle and unusable.In the end, an endless steel strip with joints is never homogeneous as a whole in either shape or strength (the copper strip is not alloyed). The endless bandsaw used for this purpose cannot be expected to be of the highest quality in terms of accuracy or strength.

質切断用無端帯鋸が提供される。(Means for Solving the Problems) In order to solve these problems, according to the present invention, an ultra-thin endless steel strip is formed by rolling a steel pipe without joints, and the endless steel strip is rolled. Diamond or cubic boron nitride abrasive grains are bonded to one end of the band by electroplating or electroless plating, or a metal powder sintered body or resin powder containing diamond or cubic boron nitride abrasive grains is used. There is provided an endless band saw for cutting hard materials, characterized in that the sintered body is welded, brazed or bonded.

完全に均質なものとなる。By drawing or turning a steel pipe, which is a completely unconnected material from the beginning, and rolling it using spinning or rolls to thin the wall thickness of the steel pipe, it is possible to create an endless material that becomes the alloy for endless band saws. Since a steel strip is formed, the endless steel strip has no joints at all, has the desired wall thickness (thickness of 0.1 nm or less is also possible), and is completely homogeneous over the entire circumference. .
