Abstract

Lubrication is a key issue in diamond turning of hard materials. This paper explores the feasibility of nanoparticle lubrication in diamond turning of reaction-bonded SiC. Four types of nanoparticles were dispersed in lubricating grease and applied to a workpiece surface. Results showed that the type and concentration of dispersed nanoparticles significantly affected lubricating performance. Grease containing 10% Cu nanoparticles produced the highest surface quality and the lowest tool wear. Lubrication is discussed in terms of nanoparticle-induced solid lubricating film formation at the tool-workpiece interface.
