NanoTEM provides tools that are most suitable for processing wide range of materials based on this theory. By obtaining specific grinding energy of each grinding wheel, the appropriate cutting rate (cutting depth and feed rate) under specific condition can be estimated. The following formula is the definition of specific grinding energy.
