Abstract

In this paper we theoretically and experimentally justified the conditions of effective use of electroerosion diamond grinding for details with coatings of high hardness (HRC 60 and above). An assessment of the proportion of cutting energy and the proportion of energy of wheel binder friction with machined material in the overall energy balance of the electroerosion diamond grinding. We show that the proportion of cutting energy while coating grinding much less than while hard alloy grinding. This suggests that with coatings grinding the proportion of energy of wheel binder friction with machined material dominates; resulting in diamond wheel with metal binder is greased and requires intensive spark erosive actions on its working surface in order to ensure enough high cutting capacity.
