In this context, can be mentioned the need to eliminate the roundness errors that appear after the grinding process. This work has the objective of verifying if optimized nozzles for the application of cutting fluid in the grinding process can minimize the formation of the roundness errors and the diametrical wear of grinding wheel in the machining of the steel VC 131 with 60 HRc, when compared to the conventional nozzles. These nozzles were analyzed using two types of grinding wheels and two different cutting fluids. Was verified that the nozzle of 3mm of diameter, integral oil and the CBN grinding wheel, were the best options to obtain smaller roundness errors and the lowest diametrical wears of grinding wheels.209-212engCutting fluidDiametrical wearOptimized applicationRoundness errorsCutting fluidsError analysisGrinding (machining)Grinding wheelsNozzlesSteelWear of materialsArtigo10.1590/S1678-58782004000200013S1678-58782004000200013Acesso aberto2-s2.0-46443490252-s2.0-4644349025.pdf
