LOOKING AFTER WATER MIX METAL WORKING FLUIDS

1.Coolant make up, coolants should always be prepared by adding the correct quantities of product to water in a suitable clean container with agitation.
NEVER ADD WATER TO OIL CONCENTRATE.

2.
Concentration measurement, the recommended fluid strength should be checked regularly using a hand Refractometer and adjustments made to bring it back to the recommended strength if necessary.
After ascertaining the refractive index, the use of a correction factor may well be necessary in order to identify the actual concentration of the emulsion.

3.Coolant top up and concentration adjustment, when additions of fresh cutting fluid are required, it is essential to predetermine the concentration evaporation or over dilution.
Topping up with a freshly prepared mix of either a lower or higher concentration, as required, will restore the machine sump to the recommended concentration level.

4.Removal of contaminants, the cutting fluids should always be maintained in as clean a condition as possible.
To avoid premature bacterial degradation and coolant breakdown, it is essential to remove tramp oils from coolant sumps on a regular basis.
Metal swarf levels should also be kept to a minimum, by use of a suitable filtration system.

5.
System hygiene, it is equally important to ensure that debris from the surrounding workplace is prevented from entering the coolant system as this can result in premature bacterial degradation of the cutting fluid.
This is particularly pertinent when food waste, bread crusts etc.

6.
System cleaning, to obtain longer coolant life, It is recommended the use of system cleaner in the correct concentration level, prior to any used coolant change.
The system cleaner eradicates microbial presence and initiates the remo
val of accumulated debris from within the coolant system.
