6.6 Exchanging the cooling liquid
and cleaning the tank
NOTICE
Damages caused by wet
machining with unsuitable
cooling liquid
Wet machining without suitable cooling liquid can
damage the machine, tools and blanks.
Before you execute a job, ensure that the cooling
liquid is clean and the liquid level is sufficient.
Only use cooling liquid that meets the requirements
listed below.
If you use a cooling lubricant: Only add the cooling
lubricant Tec Liquid Pro to the cooling liquid.
Exchange used cooling liquid according to the main-
tenance table. Clean the cooling liquid tank before
refilling it.
If you use a cleaning agent to clean the tank, ensure
that no residues of it remain in the tank.
The machine needs cooling liquid that meets the
following requirements:
n
Drinking water – for some blank types, you must
add cooling lubricant (see below)
n
No added chlorine
n
No distilled water
n
No carbonated water
Without sufficient cooling liquid in the tank, wet
machining is not possible. You can find the appropriate
interval in the maintenance table.Of course, you can
exchange the cooling liquid at any time.
You need to exchange the cooling liquid in the
following cases:
n
The change interval in the maintenance table has
been exceeded.
n
The cooling liquid is soiled.
n
In case of a strong odor from or a biofilm on the
cooling liquid.
n
If you use a cooling lubricant: The pH value is
below 9.
Every time you exchange the cooling liquid, you must
also clean the tank.
The cooling liquid tank is dishwasher-safe. If
you use a dishwasher, select a cleaning
program with a maximum temperature of 70 °C
(160 °F). To preserve the cooling liquid filter,
you can remove it and clean it by hand.
Before every job, you also have to check the strainer
basket and empty it if required.
