Experimental investigation on performance of touch-dressed single-layer brazed cBN wheels

摘要: Electroplated single-layer grinding wheels, in spite of offering unique useful features like geometrical flexibility, large chip accommodation volume the inter-grit space, etc., produce high transverse surface roughness on ground workpiece. Non-participation all superabrasive particles (grits) attributes to this limiting factor. Moreover, plunge situation is worst deal with. This work an attempt reduce same acceptable magnitude so that post-grinding finishing operations can be executed effectively. However, procedure has been implemented indigenously developed brazed-type cBN wheels. class wheel found superior its galvanically bonded counterpart view larger grit protrusion and flexibility print any pattern distribution. In investigation, brazed wheels with different distribution patterns have conditioned by touch-dressing method tips get micro-conditioned allow underlying grits participate consequently increase quality finish. The outcome appeared highly encouraging. A substantial improvement could achieved three categories role obtaining good finish was thoroughly investigated.
