Chip Drawer

The chip drawer catches swarf and metal chips during the machining process. It contains a screen that keeps the large chips from returning to the reservoir with the run-off coolant—this prevents the chips causing pump damage.

Also, it slides open and is removable for cleaning (see Figure 87).

27⁄8 TPI

The thread dial is not used for 2⁜7⁄8 or metric threading, or diametral and modular pitches (see Figure 86). The half nut must stay engaged with the leadscrew throughout the entire threading operation.

The chip drawer is very heavy. Unless removing the chip drawer for cleaning, do not pull it out more than halfway to prevent it falling and causing impact injuries. If removing the drawer for cleaning, get assistance!
