Bacteria In Coolant Cnc Machines

A comprehensive guide for solutions to coolant and …

Letting oil remain in the coolant tank allows anaerobic bacteria to grow. Anaerobic bacteria break down the components of coolant, causing it to need changing more frequently. Oil-laden coolant with a high anaerobic bacteria content has two other drawbacks as well. The first drawback is an unpleasant odor caused by the bacteria.
