DEVELOPMENT OF DISCONTINUOUS GRINDING WHEEL WITH MULTI-POROUS GROOVES

Conventionally, grinding of aluminium, copper and stainless steel is d ifficult owing to the mechanical properties such as low hardness and h igh toughness which result in the wheel loading and poor surface finis h. In order to grind these materials easily, a discontinuous grinding wheel with multi-porous grooves has been recently developed. The multi -porous grooves were formed during wheel manufacturing. The discontinu ous grinding wheel dramatically increases the grinding performance. It is desirable to use discontinuous grinding wheel when grinding materi als with high efficiency and accuracy which is impossible using conven tional wheels. In this paper, the construction and manufacturing metho d of discontinuous grinding wheel with multi-porous grooves are explai ned. The grinding characteristics of the discontinuous grinding wheel is also illustrated. (C) 1997 Elsevier Science Ltd.
