Improvements of the MQL Cooling-Lubrication Condition by the Addition of Multilayer Graphene Platelets in Peripheral Grinding of SAE 52100 Steel

In most grinding processes, the use of cutting fluid is required, and research has been carried out to reduce amount used due costs environmental impacts. However, such a reduction can result in thermal damage machined component because may not be sufficient lubricate cool system. One way improving properties add micro or nanoparticles solid lubricants. This paper aims evaluate performance multilayer graphene platelets dispersed applied through technique minimum quantity lubrication (MQL) during peripheral surface SAE 52100 hardened steel. this sense, influence these particles with respect sub-surface integrity components was analyzed, performing roughness microhardness measurement analyzing ground surfaces. The results showed that cooling–lubrication conditions employing could obtain smaller values decreases relation reference value better texture compared conventional MQL without particles.
