| Research Abstract |
In this report, it is described that highly homogeneous pellets can be fabricated by applying electrophoretic deposition of ultrafine abrasives, and a smooth surface of less than 10nmp-v can be obtained for both hard and brittle materials by grinding with the pellets. The realization of a minute grain depth of cut is an important feature for obtaining a smooth surface by grinding. Hence it is desirable to apply a grinding wheel composed of ultrafine abrasives of diameters of 10 to 20nm. Ultrafine abrasives which are negatively charged can be deposited homogeneously on an anode by applying electrophoretic deposition. It is easy to fabricate a homogeneous ultrafine grinding wheel by applying this technique. Highly homogeneous resinoid wheel with suitable bonding strength results in grain-sized self-sharpening in a grinding process. As a result, the grinding wheel can yield a smooth surface by preventing the occurrence of swarf loading and grain dulling.
