<p>A method in which a granular abrasive, together with a deposited metal, is deposited on a base metal for an electro-cleposition on a tool by electroplating. A cathode chamber (4) is provided in an electrolytic tank (1) in such a manner that a portion of the cathode chamber (4) projects beyond the anolyte surface Sa. A granular abrasive layer (8) is formed on the bottom of the cathode chamber (4). A portion of an anolyte in an anode chamber (7) is circularly poured into the cathode chamber (4) from the upper side thereof such that a head difference (Sc-Sa) is formed between the catholyte surface Sc and the anolyte surface Sa, whereby such plating conditions as the pH of the catholyte and the metal concentration are controlled such that the granular abrasive (8) is deposited on a base metal (3) without th diffusing the granular abrasive layer (8). The method is suitably employed to manufacture an electrodeposition plated tool in such a manner that a granular abrasive, such as diamond, cubic boron nitride or fine ceramic is deposited on a base metal for various grinding, polishing or cutting tools, together with a metal, such as nickel or copper.</p> |
