Chip Drawer

The chip drawer catches swarf and metal chips
during the machining process. It contains a
screen that prevents large chips from returning
to the reservoir with the run-off coolant and
causing damage to the pump.
Also, it slides open and is removable for cleaning
(see Figure 86).
Figure 86. Chip drawer.
The chip drawer is very heavy. Unless
removing the chip drawer for cleaning, do
not pull it out more than halfway; otherwise,
it could fall out and cause a crushing injury.
If removing the drawer for cleaning, get
assistance!
