Abstract: Superabrasive grinding is a high efficiency process used in special applications such as high speed grinding, creep feed grinding, and Quick-Point. Although the maximum efficiency is obtained by metallic bonded wheels due to their wear resistance, their hardness makes almost impossible to dress them properly. Vitrified bonded wheels are now being used instead of metallic bonded ones since they have superior self-dressing capability. With the aim of obtaining maximum efficiency of these special grinding processes, in the last years a number of non-conventional dressing processes have been developed allowing the use of metallic bonded wheels. In this work, a methodology to introduce the electro-discharge dressing (EDD) of superabrasive conductive metallic bonded wheels is presented. The efficiency of EDD process to regenerate shaped wheels applied in Quick-Point or peel grinding has been studied by grinding hard metal rollers. Results show that EDD is able to remove the run-out and regenerate cutting capability.
