The coolant system consists of a fluid tank, pump,
and flexible nozzle. The pump pulls fluid from the
tank and sends it to the nozzle, which controls
the flow of coolant. As the fluid leaves the work
area, it drains from the chip drawer, where the
swarf and metal chips are screened out, through
the drain chute, and back into the tank. The chip
drawer slides open and is removable for cleaning.
Use
Figures 120–121 to identify the locations of
the coolant system controls and components.
Coolant System
Service
Although most swarf from machining operations is
screened out of the coolant before it returns to the
tank, small particles will accumulate in the bottom
of the tank in the form of sludge. To prevent this
sludge from being pulled into the pump and dam-
aging it, the pump’s intake is positioned several
inches from the bottom of the tank. This works
well when the tank is regularly cleaned; however,
if excess sludge is allowed to accumulate, the
pump will inevitably begin sucking it up.
Hazards
As coolant ages and gets used, dangerous
microbes can proliferate and create a biological
hazard. The risk of exposure to this hazard can
be greatly reduced by replacing the old fluid on a
monthly basis, or as indicated by the fluid manu-
facturer.
When working with the coolant, minimize expo-
sure to your skin, eyes, and lungs by wearing
the proper PPE (Personal Protective Equipment),
such as long-sleeve waterproof gloves, protective
clothing, splash-resistant safety goggles, and a
NIOSH-approved respirator.
BIOLOGICAL & POISON
HAZARD!
Use correct personal
protection equipment
when handling coolant.
Follow federal, state,
and fluid manufacturer
requirements for proper
disposal.
Chip drawer is very heavy. Unless removing
chip drawer for cleaning, pull it out less
than halfway to prevent it from falling and
causing impact injuries. If removing drawer
for cleaning, get assistance!
