Abstract: A superabrasive tool such as a superabrasive grinding wheel (101; 102), a superabrasive dresser (103; 104; 105), or a superabrasive lap plate (106) has a steel base (20) and a superabrasive layer (10) formed on the base (20). The superabrasive layer (10) includes superabrasive (11) consisting of diamond grains, cubic boron nitride grains, etc. and a holding layer including a nickel plating layer (16) holding the superabrasive (11) and fixing it to the base (20) and a bonding material layer (17) or a soldering material layer (18). Grooves (12) or holes (14) are formed in the flat surface (19) of the superabrasive (11) exposed from the holding layer (16 and 17; 18). The holding layer (16 and 17; 18) which holds the superabrasive (11) in such a way that the surface of the superabrasive (11) partially exposed is formed on the base (20). A laser beam (50) is applied to the surface of the superabrasive (11) exposed from the holding layer (16 and 17; 18) to form the grooves (12) or the holes (14). By forming the grooves (12) or the holes (14) in the surface of the superabrasive (11), high precision grinding can be performed.

Abstract: A wire saw is provided that suppresses mechanical damages and chemical damages of a wire rope, the latter being generated due to the generation of rust and that has a long life and high durability. A diamond wire saw (100) comprises a wire rope (110), a plurality of grinding members (2), and a rubber elastic member (40). The wire rope (110) includes a plurality of strands (102a-102g). Each of the strands includes a plurality of yarn elements (101). The wire rope (110) has a first gap (104) between the plurality of strands and second gaps (103a, 103b) between the plurality of yarn elements. The elastic members (40) fill at least 20 % of the gaps comprising the first gap (104) between the strands and the second gaps (103a, 103b) between the yarn elements.

Abstract: A wire-saw used for cutting an electronic or optical material and its manufacturing method. Abrasive grains (3) whose particle diameters are not less than 2/3 of the thickness of a resin bonding layer (5) and not larger than 1/2 of the diameter of a high strength core wire (2) are fixed to the outer circumference of the core wire (2) with the resin bonding layer (5) which contains a filler (4) whose particle diameter is less than 2/3 of the thickness of the resin bonding layer (5) in such a way as to protrude from the surface of the resin bonding layer (5). By using a wire-saw (1) having such a construction, cutting can be performed efficiently with high cutting precision. Such a wire-saw (1) can be manufactured easily by using an enamel seizuring furnace.

Abstract: This invention provides a superhard film-coated material consisting of a superhard film of diamond or the like, and a superhard alloy base material to which the film is fixed firmly; and a method of producing the same. According to the present invention, a superhard alloy base material is heat treated so as to deposit hemispherically on the surface of the base material a combined metal in the portion of the base material which is close to the surface therhof. This invention is characterized in that diamond and/or diamond-like carbon is formed by a chemical vapor phase synthesis on the surface of the base material by leaving the deposited metal as it is or removing the deposited metal partially or wholly. Owing to the formation of this deposited metal, the combining force of the superhard film and superhard alloy base material increases remarkably, and the formation of a thick film becomes possible.

Abstract: A plurality of abrasive sleeves (3) surround a wire rope (2) and are spaced at predetermined intervals longitudinally of the wire rope. An elastic material (4) of rubber such as natural rubber is formed between the abrasive sleeves in such a manner as to surround the wire rope. A rubber/metal bonding agent (7) such as chlorinated rubber type bonding agent is used to effect vulcanization bonding between the opposite end surfaces of each abrasive sleeve and the elastic material and between the wire rope and the elastic material. The ends (19) of the wire rope are connected together by a combination of end connecting members (5, 6a) provided with male threads (17, 17a) and fixed to the ends of the wire rope and a internally threaded connecting sleeve (30), whereby a closed loop is formed.
