Chiller Unit; Lubrication - Mazak STX SC L PLUS CONTROL Training Manual

Chiller Unit

A> The chiller reservoir must be filled with distilled water, a corrosion inhibitor and a
fungicide. A level gauge is located on the side of the chiller unit to indicate the fluid
level. The reservoir holds approx. 40 gal.
Recommended corrosion inhibitor:
Recommended bactericide/fungicide: "GAX - 26"
B>The air pressure gauge must be set at 5.0 Kg/cm2 by adjusting the air out regulator.
C>
valve.
Water bypass valve location: Below water pressure gauge.
D>
E> The chiller unit must be flushed every 6 months if the recommended corrosion inhibitor and
fungicide are used. (See pg. 22 for flushing procedure )
NOTE: If the recommended corrosion inhibitor and fungicide are not used, the flushing
interval is every 3 months.
Recommended flushing agent: "CITRANOX" ( 1 gal. / 50 gal. Of water )
F> The chiller heat exchangers must be kept clean by vacuuming or blowing out with
compressed air. DO NOT place additional filters over the heat exchangers. This will reduce the
air
flow and cause the compressor to work much harder to maintain the proper temperature.
G> The air entering the chiller must be very clean and dry before it enters the chiller air filter
system. These filters are not meant to be the primary dryer system for the air supply.
The chiller air filters need to be checked every 1000 hours and replaced as necessary.

Lubrication

A>Lubrication of the chip conveyor chain must be performed once per month. (Light
machine oil)
B>The centralized automatic lubrication system requires oil as needed. (Alarm occurs
when low) It will lubricate the ball screws and LM guides for all axes.
STX SC: (Mobil Vactra Oil No. 2)
The water pressure must be set at 3.5 Kg/cm2 by adjusting the water bypass
The chiller temperature must be 17.5 degrees Celsius + or - 1 degree.
