Your metalworking fluids serve as the lifeline of your shop, allowing for increased production, longer tool life, and more efficient chip removal. Use the information below to help pinpoint the cause of the most common metalworking fluid issues and potential ways to resolve them.
Check the concentration: A mix that is too rich can contribute to foaming. Check concentration with a refractometer and adjust.
Mechanical problems: Check for a leak on the intake side or around the shaft seals of a coolant pump, which would result in air being drawn into the fluid, creating foam.
RUSTING OF PARTS:
The coolant mix is too lean: Check the concentration with a refractometer and adjust if necessary.
The pH is too low: Check pH with paper or a meter to ensure its above 7.5. If rust occurs, add 2% concentrate to sump and check the concentration again.
SHORT SUMP LIFE:
The concentration is too low: Check concentration with a refractometer and adjust if necessary.
The tramp oil is sealing surface of sump: Take steps to reduce or remove floating tramp oils to prevent the rapid growth of anaerobic bacteria
HEAVY OR STICKY RESIDUES:
The coolant concentration is too rich: Check the concentration with a refractometer and adjust as necessary.
Excessive tramp oils contamination: Tramp oils can build up and coat machine surfaces. Use a skimmer to reduce or remove floating tramp oils.
