Jan 08 2019 · It is therefore a good idea to keep the content of the cooling water tank circulating. Liquids in the lines connected to the CNC machine can also be a hotbed for bacterial growth. It pays to keep an eye on this—by regularly checking and cleaning the lines for example—and to make sure that bacteria

Oil Skimmers Coolant Consultants Inc.

Why should I have oil skimmers on my machines In most machine tool coolant systems and detergent wash systems tramp oils are the number one contaminant. In coolant systems tramp oils collect on top of the coolant sealing off oxygen and promoting the growth of anaerobic bacteria. The bacteria feed on tramp oils and the components of the coolant.

Why Machine Coolant Becomes Unusable

Surprisingly there are people who find it easy to confuse machine coolant sumps and holding tanks with toilets or food disposal units. Poor housekeeping practices add huge numbers of microorganisms to the system. Bacteria also live in the sludge that settles in machine sumps and machine coolant flumes. In short bacteria are everywhere.
