Abstract
Good results were obtained in the application of diamond grindstones produced by electrodeposition to honing. These stones were superior to ordinary vitrified stones in their life (almost 20times as long as that of the latter) and honing power. The above properties depended in their manufacturing processes such as the depth of the plated layer wherein diamond particles are embedded, conditions of electro-deposition (for example, kinds of baths which have effects on the hardness of deposit), etc.
For instance, the following stone proved effective in the honing of cast iron FC-20 and resulted in the life of 20times as long as that of ordinary vitrified stones; the ratio of the depth of plated layer in the above stone was about 90% (based on the average shuter diameter of diamond particles), and the hardness of bright nickel plated layer was about Hv 400.
