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 88).

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!

Coolant System

When the coolant pump is turned ON, the fluid is delivered through the nozzle attached to the carriage. The flow is controlled by the valve lever at the base of the nozzle (see Figure 89).

Always use high quality coolant and follow the manufacturer's instructions for diluting and maintenance. The quick reference table shown in Figure 90 can help you select the appropriate fluid.

Refer to Coolant System Service on Page 74 for detailed instructions on how to add or change fluid. Check the coolant regularly and promptly change it when it becomes overly dirty or rancid, or as recommended by the fluid manufacturer.

General Note: Coolants are used for heavy-duty lathe operations and production turning. Oil-water emulsions and synthetic cutting fluids are the most common for typical lathe operations. Sulferized oils often are used for threading. For small projects, spot lubrications can be done with an oil can or brush, or omitted completely.
