Extreme pressure (EP) additives such as sulfur, chlorine and/or phosphorous compounds are used in cutting fluids in order to reduce wear and friction, and to cool cutting tools and workpieces. Recently, it has been reported that overbased sulfonates showed good performance as EP additives in tapping and pipe threading efficiencies. However, the effect of sulfonates on the tool wear has not been investigated in the report. This paper deals with the performance of calcium (Ca) sulfonates on tool wear and finished surface roughness in continuous cutting (turning) and in intermittent cutting (hobbing). Both in turning and in hobbing, Ca sulfonates decreased tool wear and improved surface finishes. It was also observed that the interaction between sulfurized fatty oil and Ca sulfonate has an effect on tool wear and finished surface, suggesting synergism.
