This paper deals with the grinding effects of electroplated ring CBN small diameter quill in face grinding of bottom of grooves. Firstly, the structure of ring CBN quill is designed based on theoretical analysis of thickness of grain. In face grinding with ring CBN quill, the grinding force increases rapidly and wheel life is short because the coolant does not reach the grinding region easily. As one of the methods, the coolant supplying method and tilted spindle method have been discussed. Several results,have been obtained:(1)the thickness (the difference between outside radius and inside radius)of ring quill is an important factor for depth of grain cut; (2)the through hollow spindle coolant supplying method is beneficial to wheel life; (3)the tilted spindle grinding method is very effective for ring CBN quill face grinding.
