Different techniques used to measure the hardness of the grinding wheel based on the grinding wheel surface of various grain sizes and the bond contents present in the wheel structure. Two different techniques are identified to accept entirely their capacity to differentiate the wheels of various commercial hardness. In production industries, hardness of the grinding wheels is one of the key parameters which shows its strength of the grinding wheel. During the operating condition (dynamic), is the first method to easily relate in the workshop, quite more complex to analyze. One more technique in research studies of grinding wheel hardness obtained through statistical analysis result. This research highlights the further improvement of hardness of grinding wheel by combining two different abrasive materials (Al2O3 with Boron nitride). By mixing these two abrasive materials with vitrified bonding system involves the adjustments in order to maintain grinding performance, mainly the wheel hardness, grain holding capability, cutting strength, and wheel safety during the machining. It is a major outcome on mixing proportion, mixing quality, stability, and skill to manage the wheel in its green state during the heat treatment, while the proper composition of the bonding material tends to influence the strength and hardness of the grinding wheel. The present work reports the influence of the hardness of the wheel in terms of improving the wear rate and durability and power consumed during the grinding operation which highly affects the grinding business. The final parts of this article give the improved hardness of the grinding wheel and combined grain topography, wheel morphology would represent a clear step development of grinding wheel technology and that each of value in its own sphere of application in grinding.
