Development of Sintered Composite Stick for Dressing CBN Grinding Wheel

Abstract

This paper proposes dressing performance of a new sintered composite of iron powder electrolytic and oxide abrasive. Under constant dressing condition good dressing performance is observed in the composition of stick that contain 40% aluminum oxide abrasive (MA 220), 0.5% carbon and 59.5% electrolytic iron powder, or 30% aluminum oxide and electrolytic iron powder in balance. The consumption of dressing stick in service is nearly about 1/12 that of WA stick commonly used and grinding force is markedly decreased in stable state even just after dressing treatment.
