Abstract: This paper describes the grinding force characteristics of electroplated small diameter CBN quills when face grinding the bottom of deep-grooves. When face grinding with CBN quills，the grinding force increases and decreases rapidly in the initial stage of wheel grinding and increases with the cumulative wheel grinding stock removal. There are four types of CBN grain damage , viz falling off，broken，chipping and worning in down the grinding process. They cause unsteadiness in grinding force and its continued increase in grinding force.

Key words: Key words electroplated CBN quill , face grinding , grinding force , grain breakage
