MANUFACTURE OF THIN EDGE ROTATING GRINDSTONE FOR CUTTING

PURPOSE:To prevent the damage of the cutting function that a joining interface is projected at the peripheral edge part of a grindstone while under cutting work and the peeling off of the metal layers of both parts on the joining interface, by forming the state of two layers super abrasive grains are bitten each other on the joining interface of a 1st metal layer. CONSTITUTION:A super abrasive grain 3 is fixed on a substrate 1 by precipitating a 1st metal layer 4 on the conductive plane substrate 1 where a super abrasive grain 3 is deposited in a plating liquid. The metal layer 4 containing this super abrasive grain 2 is peeled off from the substrate 1. The precipitated metal is removed until the super abrasive grain 3 is exposed by executing etching on the face 6a which was brought into contact with the substrate 1 of this peeled off 1st metal layer 4. The super abrasive grain 3 is again deposited on the face where the etching of this 1st metal layer 4 is executed and by precipitating a 2nd metal layer 8 in the plating liquid as well a deposited super abrasive grain 7 is fixed on the face where the etching of the 1st metal layer 4 is executed and a desired thin edge rotating grindstone for cutting is obtained.
