Cooling agents and chips disposal

The quality of the cooling
agent will deteriorate due to:
•
use of contaminated water
•
impurity
•
outside oil contamination
(hydraulics, gears)
•
high operating temperatures
•
lack of air circulation
•
wrong concentration
4.7.1.

Coolant device inspection

The state of the cooling agent has significant influence on the cutting quality and on
the operational life 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 cooling liquid (especially with oils) and on the other factors.
Check level of the cooling liquid and function of the pump periodically!
Note:
If the state of the cooling liquid is not satisfactory, the cooling
liquid must be changed.
Check the state of the cooling agent according to the following table:
Testing Interval
Liquid level daily
Concentration daily
Smell daily
Contamination daily
Corrosion- when
protection necessary
when
Stability
necessary
when
Foam reaction
necessary
* According to manufacturers' instructions
4.7.2.

Chips disposal

Chips resulting from cutting operations must be disposed of in accordance with the
relevant regulations.
•
Let the chips drip excess fluid!.
•
Fill a watertight container with the chips! Be careful that the container does not
leak, because even after a long dripping time, they still contain coolant residue.
•
Place the container into the care of a disposal company equipped for the disposal of
chips contaminated with cooling liquid. In case the machine is equipped with micro-
spray installation, the chips must also be handed over to a disposal company.
If the solution is too weak:
•
corrosion protection is
diminished
•
lubrication decreases
•
microbial attack is more likely
Method Condition
visually too low
too high
refractometer
densimeter
too low
by sense of smell unpleasant smell
visible oil leaks,
by sense of smell
sludge fungi
visually
insufficient corrosion
chip test
protection
Herbert-test
refractometer oiling
too much foam, foam
shaking test
disperses too slowly
If the solution is too strong:
•
the cooling ability is decreased
•
foam behaviour increases
•
emulsions stability deteriorates
•
sticky residue develops
Precaution
after concentration check, refill
with water or emulsion
refill water
refill base emulsion
good ventilation, add biocides
or renew coolant
surface cleaning, fix leaks, add
biocides or fungicides, or
coolant renewal after added
system cleanser*
test stability, if necessary –
increase concentration or pH
value
add concentrate, enquiries to
supplier
avoid aeration, increase water
hardness, ix with defoamer
