Cutting Fluid System; Steady Rest & Follow Rest - Grizzly G0709 Owner's Manual

cutting fluid System

the cutting fluid system delivers cutting fluid via a
flexible distribution hose and nozzle. the cutting
fluid pump turns on and oFF with a switch locat-
ed on the control panel. Fluid flow is controlled by
a manual flow control valve near the base of the
distribution hose (see figure 43).

NOTICE
Running the pump without adequate cutting
fluid in the reservoir may permanently dam-
age it. This type of damage is not covered
by the warranty.
Always use high quality cutting fluid and follow the
manufacturer's instructions for diluting. Frequently
check the cutting fluid condition and change it
promptly when it becomes overly dirty or rancid.
refer to cutting fluid on page 58 for changing
the fluid or filling for the first time.
To use the cutting fluid system:
1.
Make sure the cutting fluid tank is properly
serviced and filled.
2.
position the cutting fluid nozzle as desired for
your operation.
3.
use the control panel switch to turn the cut-
ting fluid pump ON.
4. Adjust the flow of cutting fluid by using the
valve lever at the base of the nozzle hose.

Selecting and Using Rests
to minimize deflection, in workpieces like rods,
dowels, tubes, and small diameter solid shafts,
the steady rest or follow rest is used.
the steady rest is clamped to the ways and sup-
Flow valve
ports the workpiece with three fingers at a single
point between the chuck and the tailstock.
the follow rest is bolted to the carriage and travels
with it during turning or threading operations. two
fingers support the workpiece while the tool tip
acts as the third support during cutting.
Both the steady rest and the follow rest use ball
bearing-tipped fingers instead of solid brass tips.
the fingers have a guide slot where the tip of
an adjustable set screw rides. these screws are
held in place with jam nuts. the set screws must
be tightened inward far enough so they bottom
slightly, providing preload and keeping the finger
in alignment with only slight rocking in its bore.
When using either of these rests, keep in mind
that most machining operations must be done at
low spindle speeds to prevent a workpiece ejec-
tion hazard.
