In this paper, the performance of various emulsions in water soluble cutting fluids for hobbing was investigated with TiN and (Al, Ti) N coated tools, in terms of flank wear, crater wear and finished surface roughness. Experiments were carried out using a fly tool. The results helped clarify the following points; (1) With both TiN and (Al, Ti) N coated tools, an emulsion containing synthetic lubricating additive is effective for decreasing the flank wear and the crater wear, irrespective of the change in the cutting speed. (2) It was suggested that a polyalkyleneglycols contained in the emulsion has a tool wear reduction effect, and the reason why the decrease of the crater wear when using the emulsion is due to the protective action by the deposited metal on the rake face. (3) There was no difference in the finished surface roughness obtained with the various emulsions even when changing the cutting speed. (4) In the view point of the tool wear and the surface finish, the emulsion containing synthetic lubricating additive is available for the (Al, Ti) N coated tool in hobbing.
