- Abstract
In this study, nano-sized MoS2 was mixed into coolant and was turned with GGG-70 spheroidal graphite cast iron. Surface roughness and tool wear were analyzed and effects of nano-MoS2 on machinability were investigated. Cutting tests were carried out at 350 m/min cutting speed, 0.2 mm/feed rate and 4 mm cutting depth. Surface roughness (Ra) values and cutting tool wear obtained under dry cutting, conventional cooling, Minimum Quantity Lubrication (MQL) and 3 different nano-MoS2 added MQL conditions were investigated. Highest average Ra value was obtained under dry turning conditions. Roughness value decreased at conventional cooling, MQL and nano MoS2 added MQL conditions. A 37% reduction in Ra was obtained with respect to dry processing conditions. The lowest Ra 7 bar pressure, 160 ml/min flow rate and MQL + 1.5% nano-MoS2 spray was measured at 0.99 μm.
