Claims

[Scope of Claim for Utility Model Registration] (1) A rim plate-shaped abrasive grain-containing hard rubber grinding stone material, and two pieces having an outer diameter comparable to the inner diameter of the ring existing in the ring-shaped space of the grinding stone material. It essentially consists of an inner circle support material made by joining the above disc-shaped support materials with a polymer adhesive material, and the rim-shaped grindstone material and the inner circle support material are integrally joined together with a polymer adhesive material. A disc-shaped cutting whetstone featuring a curved structure. (2) The cutting whetstone according to claim 1, wherein the disc-shaped support material is one or more types of support material selected from fiber-reinforced resin plates, metal plates, and ceramic plates. (3) Utility model registration claim Paragraph 1, in which the disc-shaped supporting material is composed of three or more disc-shaped supporting materials, and the external supporting material and the internal supporting material are different types of supporting materials. Or the cutting wheel described in Section 2. (4) The rubber component of the rim-shaped grindstone material and the adhesive material of the inner circle support material are bonded by fusion hardening;
A cutting whetstone according to claim 1, 2 or 3 of the scope of utility model registration. (5) A request for utility model registration in which the inner circular end of the rim-shaped grindstone material is joined by forming a protruding part in the gap between two or more disk-shaped supporting members and/or at the outer end of the supporting members. Cutting wheel in range 1, 2, 3 or 4. (6) A request for utility model registration in which the disc-shaped supporting material is composed of three or more disc-shaped supporting members, and the internal supporting material is a disc-shaped supporting material smaller in diameter than the external supporting material. A cutting whetstone according to any one of the ranges 1 to 5.
