Cutting Fluid Drag-out and Exhaust Air in Grinding Processes: Influence on the Eco-efficiency

In grinding cutting fluids are crucial to enable an efficient cutting process and to achieve a positive surface quality. Moreover, cutting fluids are also important regarding the eco-efficiency. A relevant share of cutting fluid is lost due to drag-out via chips, workpiece, evaporation and exhaust air. Especially the latter depends on the selected process setting and thus represents a manipulable factor. Therefore this paper presents a method to measure the exhaust air related drag-out. Based on experimental studies influencing parameters are investigated and their impact on eco-efficiency is discussed.
