Experimental investigation on grinding performance of microcrystalline alumina abrasive grinding wheel for superalloys
Superalloys are widely used in the aeronautic and astronautic industries owing to their excellent properties in aspects of high-temperature strength,heat stability and thermal fatigue resistance.However,the severe loading of grinding wheel and the poor integrity of grinding surface usually become the problem in grinding of superalloys with conventional grinding wheels.In this paper an experimental study was carried out to investigate the grinding characteristics of superalloys with microcrystalline alumina abrasive wheel.The roughness of grinding surface was tested,on which the effects of the grinding parameters were analyzed.Study results indicated that low loading of grinding wheel and high quality of grinding surface (Ra 0.2 μm) were obtained.The grinding parameters were optimized based on the experiment results.
