7: MACHINE MAINTENANCE
l Use a chip brush to clean the machine, chip trays, and
enclosure of chips and other swarf.
l Empty the chip strainer on the coolant tank.
l Measure the coolant concentration, pH, and volume, and
then compare your findings to the material's safety data
sheet (SDS).
o
Coolant Level Too Low Fill the coolant tank with
fresh coolant, making sure that it is the appropriate
concentration.
o
Coolant pH Outside of Manufacturer's
Recommended Coolant Limits Adjust the pH
according to the manufacturer's recommendation.
Note: You must only use coolant that is
recommended for machining. See "Cutting
Fluid Reference" (below).
l Examine the coolant pump's impeller for blockages.
l Use a Floating Tramp Oil Collection Pillow (PN 31925) or
an oil skimmer to remove tramp way oil from the
coolant tank.
Periodically do the following:
l Remove the coolant tank covers and the chip strainer,
and then clean the fine swarf from the coolant tank.
l If you're using a filter to prevent small particles from
entering the coolant tank, replace it when it's saturated
with chips, swarf, or tramp oil.
l Examine the coolant for contamination, and determine if
the coolant's oil-water emulsion has broken.
l Drain and thoroughly clean the coolant tank, and then
replace with fresh coolant.
NOTICE! Hazardous Waste:Only dispose of coolant
as advised by local environmental protection
authorities. You must not dispose of coolant in a
septic system or a sewer.
7.3.1 About Cutting Fluid
Clean and well maintained coolant has increased performance,
prevents rust, and smells better than contaminated coolant.
Coolant becomes contaminated when:
l Swarf accumulates in the chip pans, the chip strainer, or
the coolant tank.
l Tramp oil isn't regularly removed from the coolant tank.
l The concentration or pH aren't maintained to the
manufacture’s specifications.
7.3.2 Cutting Fluid Reference
Using flood coolant provides the following benefits:
l Cools the cutting zone
l Flushes away swarf
l Lubricates the cutting tool
l Provides some degree of rust inhibition
You must only use flood coolant that is recommended for CNC
machining applications, like:
l Soluble oils
l Semi-synthetic coolants
l Synthetic coolants
You must never use:
l Coolant without rust inhibitors
l Flammable coolants such as alcohols, diesel fuel, or
kerosene
WARNING! Fire Hazard. The machine and its
enclosure are not designed to contain fire or
explosions. Only use materials and coolants
that are intended for the specific machining
operation. Never use flammable or explosive
items.Before operating the machine in any
way, you must read all Safety Data Sheets
(SDSs) for any workpiece materials, coatings,
coolants, lubricants, and other consumables
used.
l Straight cutting oil
l Water
If you use a coolant concentrate, you must mix it with water to
the dilution ratio recommended by the coolant manufacturer.
Use an optical refractometer to measure coolant
concentration.
7.4 EXAMINE THE ENCLOSURE WINDOWS
Regularly examine the enclosure windows, and all other
guarding, for signs of wear or damage.
When required, replace the windows with: Window, 8L,
Enclosure Door (PN50513)
