Electroplated tools are produced by fixing grain with single layer nickel plating. With the excellent grain protrusion, they have excellent cutting ability and removal speed. Since grains are fixed by plating method, forming wheels of complicated shape can be produced comparatively easily, given the steel core can be made.
Although the embedding depth of grains should be determined depending on the grinding condition, generally 60%, and for heavy grinding and corner grinding 70% should be adequate.

Double-Layer Plates
Double-layer plates are made by fixing second layer grains with nickel plating after fixing grains with a single layer nickel plating. The first layer maintains cutting ability while the second layer, which is preserved strongly, shows extraordinary long-life in work including heavy grinding and boring of non-ferrous such as glass.
