Abstract
Electroplated diamond tools with superior proportional limit and wear resistance are developed for grinding hard and brittle materials. Application of Ni-coated diamond abrasives is effective for high-speed manufacturing of electroplated grinding tools. However, the sharpness of the grinding tool decreases because nickel membrane was attached on the surface of abrasives. The phenomenon of abrasives aggregation is also serious. In this study, we developed partially Ni-coated diamond abrasives. The production method of the partially Ni-coated abrasives was described and the effect of application of the abrasives was investigated. As the results, the problems with using Ni-coated abrasives or non-coated abrasives could be solved and the grindability of electroplated tools was improved.
