Influence of the type of coolant lubricant in grinding with CBN tools

Oil and emulsion are two main grinding coolant lubricants (CLs) used in grinding processes with CBN tools. A comparison of these two CLs was performed as part of the long systematic research made by KSF. The comparison criteria presented in this paper are grinding forces and G-ratio. The results show that oil presents better function almost in every case for the selected grinding parameters and workpiece. However, it should be noted that the results could probably be different with other types of oil and emulsion.
