This paper aims to clear experimentally the influence of a coated cemented carbide tool and fluids on the surface roughness in the ultra-precision cutting of stainless steel SUS316. The experiments are executed by face-turning SUS316 with the cutting tool set on the ultra-precision lathe. The cutting fluids used are kerosene and water-immiscible cutting fluid. First of all, the influence of cutting fluid on the surface roughness is investigated. Kerosene is generally used as the cutting fluid in ultra-precision cutting of aluminum alloy, copper and so on. The surface measurement results indicated that the surface is rougher than Rz=100nm(P-V) at the short cutting length of 100m with kerosene. In the case of water-immiscible cutting fluid, on the other hand, the surface roughness is smother than Rz=50nm(P-V). Furthermore, it is found that the commercial coated tool is more useful for the ultra-precision cutting of SUS316 in no use of special equipments. The surface roughness of SUS316 is kept smoother than Rz=100nm(P-V) until the cutting length of 1,000m.
