Electroplated diamond tools are developed for grinding hard and brittle materials because of its low wear resistance. A single layer of diamond abrasives is electroplated on the tool body for improving the grinding performance of diamond tools. The electroplating process delivers a homogeneous layer with diamonds embedded in nickel alloy at high speed. In this paper, in order to improve the grinding performance of diamond tools, authors developed partially Ni-coated diamond abrasives, which were produced from the commercially available full Ni-coated diamond abrasives. The grind-abilities of diamond tools, which are fabricated with using non-coated diamond abrasives, Ni-coated diamond abrasives and partially Ni-coated diamond abrasives, have been evaluated. As the results, the problems when using non-coated diamond abrasives or Ni-coated diamond abrasives could be solved and the grind-abilities of electroplated tools were improved with using partially Ni-coated diamond abrasives.
