The grinding of uranium and its alloys is not very well understood, and the existing information that relates grinding process parameters and grinding wheel structure to the grinding performance is outdated at best. Since the initial papers published on grinding uranium were published more than 30 years ago, advances in grinding and the development of abrasive grains and bonding systems have accelerated to such an extent that the old published data is not very reliable. Therefore, this chapter explains the current advances in abrasive grain technology and also covers the recommendations made by previously generated data and how the data could be improved using the new types of grains and bonding systems.
