The performance of three water-based grinding fluids was analyzed and compared to a neat oil tested under the same process conditions. Light optical and scanning electron microscopy observations show the mechanism of metal deposition that leads to CBN wheel failure for water-based fluids. To improve the performance of the water-based fluids, a new nozzle layout is proposed that would prevent metal deposition on the CBN wheels. The proposed solution is not chemical, but mechanical in nature and the presented setting should be optimized in the future to assure satisfactory performance of the CBN wheels with water-based fluids.
