B-6 REGULAR INSPECTION
5.
CLEANING THE COOLANT TANK
If fine chips and other foreign matter accumulate in the coolant tank, the specified coolant supply
cannot be maintained and coolant supply to the cutting point is insufficient.
In addition, if contaminated coolant is pumped from the coolant tank, the service life of the pump is
reduced.
Clean coolant tank periodically.
<Cleaning interval>
Every 500 hours of operation
(1) When machining cast iron or similar material that generates fine chips, clean coolant
tank more frequently.
(2) A certain amount of lubricant also runs into the coolant tank. Even if no coolant is
used in machining, clean the coolant tank at regular intervals.
(3) The cleaning interval may differ depending on the machine model. Refer to the
REGULAR INSPECTION LIST in the MAINTENANCE INFORMATION published
separately.
<Procedure>
1) Press the coolant switch
(off) to stop coolant supply.
2) Turn off the power.
3) Loosen the connector and remove coolant motor pipe and wiring.
4) Remove the drain plug and discharge the coolant of the coolant tank.
5) Pull out the coolant tank.
Some models have the coolant tank integrated with the bed, making it impossible to
remove the coolant tank.
6) Clean the inside of the coolant tank and the coolant filter.
7) Wind seal tape onto the drain plug and fit it to the coolant tank.
8) Mount the coolant tank to the machine.
When installing the machine, mount the coolant tank and the chip bucket by pushing
them into an appropriate position. Otherwise, coolant may be splashed around the
machine causing the operator or persons around the machine to fall and injure
themselves.
9) Connect the coolant motor pipe and wiring.
10) Supply coolant in the tank.
For the capacity of the coolant tank, refer to the OILING CHARTS in the
MAINTENANCE INFORMATION published separately.
