Experimental investigation of recycled machining coolant mixed with nanofluids based Al2O3

Machining coolant is used in manufacturing industry for lubrication, rusting control and cooling which are crucial in operations such as grinding and cutting process. However, the machining coolant lose efficiency in months due to the thermal degradation and contamination. To recycle the used of mac...
