• This paper presents the influence of Ca sulfonate on tool life (flank wear), crater wear and finished surface roughness in hobbing. Experiments were carried out using two kinds of fully coated fly tools with TiN and (Al, Ti) N films respectively. As the results, when using the TiN fully coated tool, Ca sulfonate prolongs the tool life, and decreases the crater wear compared with the machine oil 23 as a base oil. With the (Al, Ti) N fully coated tool, an interesting result was obtained that the base oil containing no additives gives a longer tool life and a smaller crater wear than those obtained with Ca sulfonates added. It was suggested that the increase in the flank wear and the crater wear is caused by the chemical and/or the corrosive actions of Ca sulfonate, when Ca sulfonate was used for the (Al, Ti) N coated tool. Ca sulfonates improve the finished surface roughness for both coated tools.
