dc.description.abstract | Wheel wear is a critical issue for grinding process optimization. This is why it receives so much attentionboth from Academia and industry. The development of new generations of abrasive wheels requiresimproving the understanding of the mechanisms involved in the loss of abrasive capacity of the wheels.In the case of alumina wheels, which are largely used in many grinding operations, the development ofmicrocrystalline sintered alumina grains is one of the most important innovations to emerge since theearly 1980’s. In comparison with white fused alumina this grains are characterized by higher ductility andhave approximately 5% more hardness. However, the mechanisms of occurrence of wear flats in thesenew abrasives are still to be fully understood. In this work, a novel approach to the study of the underlyingphenomena that occur during the development of wear flats in microcrystalline sintered alumina grainsis presented. Experimental results in terms of grinding forces, friction coefficient and surface analysis arepresented and compared to those obtained with conventional white fused alumina. The value of wearflat area is as much as 25% higher in the case of microcrystalline sintered alumina grains. Results will beuseful to prevent the development of grinding burns resulting from wear flat development in these newalumina wheels. | es_ES |
