Base on the principle of dressing diamond grinding wheel with GC cup w heel and the experiments, a model of the relationship
between GC granularity and
dressing efficiency of dish diamond grinding wheel is established. Through the study of the model, it reveals that: diamond grinding wheel with different granu larity and density should dress with
GC cup wheel with different GC granularity, when the density is lower and the granularity is smaller, the GC granularity sh ould be bigger, otherwise, it should be smaller. In order to insure the reliabil ity of the model, two experiments are carried out, the results as follow: the mo del is very practical, when the granularity and density of the diamond grinding wheel are 100# and 100%, in order to improve dressing efficiency, it should be d ressed with GC cup wheel which the granularity is 60#, and when the granularity and density are 200# and 100%, the granularity of the GC cup should be 100#. At last, base on the model and the experiments, the relationship between GC granula rity and the dressing efficiency of diamond grinding wheel in common use are ana lyzed, and the application of the model is extended.
