The aim of this research is to develop a CBN (cubic boron nitride) finishing hob that can cut medium-and high-hardness gears accurately and efficiently. This paper deals with the improvement in the finished surface roughness of gears that have medium hardness, achieved as a result of using cutting fluid. Cutting tests with a CBN fly tool are carried out. The influence of dead metal on the cutting edge on the roughness of the finished surface, and the cutting fluid effects on the improvement of it are elucidated. In order to determine an effective cutting fluid for improving the roughness of the finished surface in hobbing, the viscosity of cutting fluid and the content of chloride and sulfide are investigated. The effect of water-soluble cutting fluid is also studied. The results show that the surface roughness is reduced to 60-80%, compared with the surface roughness in dry cutting, by using the appropriate cutting fluid, and the surface finished with a CBN tool is smooth compared to finishing using other tools.
