- Check cooling unit for cooling lubricant
Carrying out the maintenance activities described below requires
special knowledge. For this reason, these maintenance activities
must only be carried out by staff that has received adequate training
by the machine manufacturer!
Orientation
Water-cooling equipment maintain the temperature in the cooling lubricant circuit on
a previously set value. The heat generated by the machining process is dissipated
away from the workpiece by the cooling lubricant and the cooling lubricant is cooled
down again to the preset temperate by the water cooling unit(s).
To achieve a constant temperature level in this circuit, it is necessary to include it in
the inspection and maintenance operations.
Be sure to observe the third-party manufacturer documentation and the technical
data of the respective equipment. If in doubt, contact the manufacturer of the
equipment or the cooling lubricant vendor.
Requirement
Prerequisite for effective operation within the cooling circuit is the condition of the
cooling lubricant. To check the condition of the cooling lubricant, a refractometer is
required. With the help of this instrument, it is possible to determine the
concentration of cooling lubricant in water. In addition, the monitoring features
available on the cooling unit must be checked or adjusted.
Procedure
1. General visual inspection for tightness.
2. Check condition of coolant.
3. Check fill level glass(es) (option).
4. Check flow rate sensor and record current values.
5. If necessary, readjust flow rate sensor and record new values.
6. Check temperature sensors/thermostats and record current settings.
7. If necessary, readjust temperature sensors/thermostats and record new values.
