Abstract
This paper describes the frictional properties and the lubricating performances of the various fluids used in cutting being considered as environmental protection. As the frictional test method, the PIN-DISK method is employed, and the frictional coefficient is evaluated. In the frictional test, as the lubriants, the emulsion, the water and the synthetic detergent are used. The results are compared with the case of dry cutting without any fluid. As a result, we obtained that in most cases the frictional coefficients become smaller. Moreover, the surface roughness of workpiece is measured. The results show that the surface roughness is improved well.
