Influuence of cutting fluid on ultra-precision turning of aluminum with natural diamond bite.

The examination on the phenomena which occures between cutting edge of bite and worked surface in the wet turning was conducted. As the results, it was found that similar phenomena occur even when the kinds of cutting fluid were changed. Moreover, it was found that the contributions of extreme pressure additives of cutting fluid, or the diluting rate of water-base type cutting fluid to the effects on the phenomena which dete riorate worked surface.
