Abstract

Grinding processes provide the best surface finishing amongst all manufacturing processes. The surface roughness in grinding, for example, is almost five times better than in turning. However, all grinding processes need a great amount of water to be mixed with the oil and produce the emulsion, where the proportion is 6% of oil and 94% of water. Furthermore, grinding processes such as through-feed centreless grinding demand a great coolant flow rate to maintain the high quality of workpieces. In this work, a shop floor study was carried out with the objective of reducing the use of flow rate and maintaining the quality of workpieces. Surface roughness was considered as the main response to define the quality of product. Two alternative systems using a minimal quantity of lubrication (MQL) system and directional device system (DDS) were applied to through-feed centreless grinding. The MQL system was not efficient in maintaining the quality of the workpieces and does not provide good cleaning in the grinding gap. However, the isolated use of DDS system maintained the surface roughness pattern and decreased the flow rate about 10 times.
