CHANGING TO GRIND-COOL: Changing to GRIND-COOL from soluble or mineral oil based coolants entails first thoroughly cleaning, purging and sterilising the system to eliminate resident bacteria. This can be achieved using our SYSTEM CLEANER, which is entirely compatible with GRIND-COOL and available from stock. In addition, a proper procedure for regular draining and cleaning of machine coolant systems, and coolant renewal, should be implemented. A typical renewal cycle would be 6 months.
DILUTIONS: GRIND-COOL dilutes with up to 30 parts water for grinding, milling, counterboring, drilling, and with up to 15 parts water for broaching, hobbing, tapping, sawing and reaming. To avoid creating an invert emulsion always add GRIND-COOL to water, and not water to GRIND-COOL .
