4.5. Cooling agents and chip disposal
The quality of the cooling
agent will deteriorate due to:
If the solution is too weak: If the solution is too strong:
 use of contaminated water
 impurities
 oil contamination from the
outside (hydraulics, gears)
 high operating temperatures
 lack of air circulation
 wrong concentration
 corrosion protection is
diminished
 lubrication decreases
 microbial attack is more likely
 the cooling ability is
decreased
 foam production increases
 emulsions stability
deteriorates
 sticky residue develops
4.5.1. Coolant inspection
The state of the cooling agent has a significant influence on the cutting quality and
on the lifespan of the machine. Lifetime of the cooling liquid is 1 year, after this time
we recommend change the cooling liquid. This time is dependent on the degree of
pollution of the cooling liquid (especially with oils) and on other factors.
Check level of the cooling liquid and function of the pump periodically!
Check the state of the cooling agent according to the following table:
Testing Interval Method Condition Precaution
Liquid level daily visually too low
check concentration, add
water or emulsion
Concentration daily
refractometer
densimeter
too high
too low
refill water
refill base emulsion
Smell daily by sense of smell unpleasant smell
good ventilation, add biocides
or replace coolant
Contamination daily by sense of smell
visible oil leaks,
sludge fungi
surface cleaning, fix leaks, add
biocides or fungicides; clean
the system with a cleanser*
prior to the coolant
replacement
Corrosion-
protection
when
necessary
visually
chip test
Herbert-test
insufficient corrosion
protection
test stability, if necessary –
increase concentration or pH
value
Stability
when
necessary
refractometer oiling
add concentrate, enquire the
supplier
Foam reaction
when
necessary
shaking test
too much foam,
foam disperses too
slowly
avoid aeration, increase water
hardness, fix with defomer
* According to manufacturer’s instructions
Note:
If the state of the cooling liquid is not satisfactory, the
cooling liquid must be replaced.
