Abstract:
Grinding is a critical finishing and material removal process in manufacturing, where the selection of appropriate grinding wheel materials plays a decisive role in determining productivity, surface quality, and overall process efficiency. This paper presents a comprehensive comparative study of commonly used grinding wheel materials, including conventional abrasives such as aluminum oxide and silicon carbide, as well as superabrasives like diamond and cubic boron nitride (CBN). The study systematically reviews and compares their physical properties, grinding performance characteristics, surface integrity outcomes, thermal behavior, and economic implications based on established literature published prior to 2019. Key performance indicators such as material removal rate, wheel wear, grinding forces, surface roughness, and thermal damage are analyzed and discussed with reference to cited tables and figures. The results indicate that while conventional abrasives remain cost-effective for general-purpose applications, superabrasive grinding wheels offer superior performance, longer service life, and improved surface integrity in high-precision and hard-material machining. The paper concludes by highlighting the importance of application-specific grinding wheel selection and identifies future research directions focused on advanced abrasive materials, improved bonding technologies, and sustainable grinding practices.
