Study on Grinding Wheel Manufacture

Vitrified Bonded Alumina Abrasive Wheel

Abstract

The relation between the manufacturing conditions and the resulting properties of grinding wheel was studied using the vitrified bonded grinding wheels with white fused alumina abrasive grains as a model. The manufacturing conditions studied included molding pressure, bond content and firing time. The properties studied were bending strength, Young's modulus and apparent density. The wheel properties were affected markedly by the manufacturing conditions. The results were explained through the microstructural consideration. An uniform green density after pressing was required for making a reliable grinding wheel with uniform quality.
