Electrocoated grindstone is defined to keep the single layer on top of the backing material by performing electroplating. which has long been used during old days. Advantageous points of it are described as follows: 1) While by usual method, it is rather difficult to make a complicated shape type grindstone, electrocoating method is far easier to make it only by electrocoating abrasive grains even on top of such a complicated shape material. 2) In comparison with normal grindstone, electrocoated grindstone can produce more waste and can cut well as the abrasive grains are firmly maintained with extensive protrude. However, for the reason of difficulty in truing the grindstone, imbaranced depth of cut of the grain is unavoidable and the surface of the finished area is not necessarily smooth in compared with others. Consequently, this is usually mainly used for rough grinding purpose. Thus, we have come to make a proposal for manufacturing quality grindstone by implementing an "Electrostatic-Electrocoating." And in this issue, we have performed various examinations after thorough observation on the probable evenness of spreads and direction of the grain in case of using of this new method.
