精度に狂いを生じさせて高精密製品は得られない。The known resinoid superabrasive grain wheel has problems in both the grinding layer piece a and the substrate b, and the high cost, dimensional change, and abrasive grain shape caused by the manufacturing process. There was a problem that it was difficult to manufacture high precision products based on changes. That is, the strip-shaped grinding layer pieces a were bonded one by one to the outer periphery of the base with an adhesive material. However, this method not only requires a lot of manufacturing time and cost, but also one by one is bonded with the adhesive material. Therefore, when the grinding layer piece a rotates at high speed and frictional heat is generated, the adhesive is affected, the shape of the abrasive grain layer is changed, the orientation of the abrasive grain with respect to the object to be ground is changed, and the bite is also defective. You will become fleeing and run away. Also,
The above-mentioned known base is made of aluminum or aluminum and resin as raw materials. However, since heat transfer is good in both cases, heat generated in the rotary bearing portion of the wheel is transferred to the rotary shaft, and further passes through the base. Is transmitted to the grinding layer piece. However, since the grinding layer piece and the substrate have different coefficients of thermal expansion, they cause thermal expansion at different rates to cause cracks between them to form a cause of fracture. Not only that, due to the remarkable thermal expansion of the substrate and the grinding layer, the outer diameter size also changes greatly, which causes a deviation in the grinding accuracy and a high precision product cannot be obtained.

得られる。INDUSTRIAL APPLICABILITY The present invention is based on resinoid superalloy which is used as a ceramic base 1 by mixing a binder with an aggregate of silicon carbide SiC or aluminum oxide Al 2 O 3 and pressing it into an annular shape by pressing and firing it. Since this is a method of manufacturing a base for an abrasive wheel, when compared with the heat conductivity (Kcal / m, hv, ° C) of a conventionally known aluminum base, the heat conductivity is 10/1 to 113/1. And small, ceramic base 1
Since it does not transfer heat to the resinoid superabrasive layer via, it solves all problems based on heat transfer. Moreover, when compared with the conventionally known coefficient of thermal expansion (mm / ° C) of the aluminum substrate, the coefficient of thermal expansion is as small as about 1/3, and the ceramic substrate 1 hardly expands. Solve. In addition, the result of comparing the total deformation (mm) due to the thermal expansion centrifugal force of the conventionally known aluminum substrate and the deformation due to thermal expansion (mm) is as small as about 1/3, and since the ceramic substrate 1 has little deformation due to the centrifugal force, Solve all force-based problems. The present invention also relates to silicon carbide SiC.
Alternatively, a binder is mixed with either aggregate of aluminum oxide Al 2 O 3 and pressed into a circular ring shape by pressing, and this is fired to form a ceramic substrate 1, and the ceramic substrate 1 is horizontally placed in a mold 3. A superabrasive grain layer forming space 4 is formed on the outer periphery of the ceramic substrate 1 and is placed on the outer periphery of the ceramic substrate 1.
A method for producing a resinoid superabrasive wheel obtained by supplying a mixture 5 in which a thermosetting resin is mixed with a powder material of diamond or cubic boron nitride (CBN) into the inside, press-molding with a press, and then heat-curing with an electric furnace In addition to the above effects, the ceramic substrate 1 is placed horizontally in the mold 3, and the superabrasive layer forming space 4 is formed on the outer periphery of the ceramic substrate 1. Since a mixture 5 in which a thermosetting resin is mixed with a powder material of diamond or cubic boron nitride (CBN) is supplied into the forming space 4, press molding is performed by a press, and then heat curing is performed in an electric furnace. Compared to the conventional method of adhering strip-shaped grinding layer pieces one by one, they are adhered by pouring them into the mold, so that the manufacturing method is simple and the cost can be reduced. In addition, the present invention is that the aggregate is made of either silicon carbide SiC or aluminum oxide Al 2 O 3 and the binder is mixed and pressed into a circular ring of a perfect circle by pressing, and this is fired to form the ceramic substrate 1, diamond or A mixture 5 of cubic boron nitride (CBN) powder mixed with a thermosetting resin is supplied, press-molded with a press, and then heat-cured in an electric furnace to be fitted with resinoid superfine particles fitted to the outer periphery of the ceramic substrate 1. The resinoid superabrasive grain layer 6 is formed, and the resinoid superabrasive grain layer 6 is fitted to the outer periphery of the ceramic substrate 1 and adhered by an adhesive. Therefore, similar to the above, as compared with the conventional one in which the strip-shaped grinding layer pieces are bonded one by one, the manufacturing method is simple and the cost can be reduced. The present invention also provides a ceramic base 1 by mixing a binder with an aggregate of silicon carbide SiC or aluminum oxide Al 2 O 3 and pressing the aggregate into a circular ring shape by pressing to obtain a ceramic substrate 1. A resinoid superabrasive grain 6 is formed by bonding a resinoid superabrasive grain layer 6 obtained by heat-curing a mixture 5 in which a thermosetting resin is mixed with diamond or cubic boron nitride (CBN) powder to the outer periphery of the substrate 1. In the wheel, a large number of resinoid superabrasive grain wheels were adhered with an adhesive to make the resinoid superabrasive grain wheels thicker, and therefore a large number of bolts were bolted as in the conventional method. Different from the ones, it is easy to obtain. The present invention also provides a ceramic base 1 by mixing a binder with an aggregate of silicon carbide SiC or aluminum oxide Al 2 O 3 and pressing the aggregate into a circular ring shape by pressing to obtain a ceramic substrate 1. The base 1 is placed horizontally in a mold 3 to form a space 4 for forming the superabrasive grain layer 6 on the outer periphery of the ceramic base 1, and a diamond or cubic boron nitride (CBN) powder is formed in the space 4. Mixture 5 of material mixed with thermosetting resin
In a resinoid superabrasive wheel obtained by feeding and pressing with a press and then heat-hardening in an electric furnace, a large number of the ceramic bases 1 horizontally placed in the mold 3 are polymerized to form the inside of the forming space 4. Since the mixture 5 to be supplied to the above is a resinoid superabrasive grain wheel which can be obtained by supplying several substrates at once, a mixture having a width can be easily obtained as in the above.
