Abstract
The vortex tube is a fully mechanical device capable of producing two streams of air in opposite directions,with diferente temperatures, hot air and cold air, based exclusively on its geometry, with only one air inlet. In this work the objective is to apply the cold air generated by the vortex tube in the cooling of the turning process, specifically, turning of SAE 1045 steel and cast iron FC250 with tungsten carbide insert, compared to the process dry and flood by means of temperature measurements using an infrared thermal camera. The results showed that the application of the vortex tube air cooling reduces by approximately 12% the temperature in the rake face cutting tool compared to the SAE 1045 steel dry turning. For cast iron FC250 the use of the cold air with the vortex tube the machining temperature in the tool reduces approximately 15% when compared to dry condition.
