Tip: When drilling or when tapping operations need to be done deep into a part, the quill can also be stabilized by
slightly applying the lever to add drag and preload to the quill.
To install a tanged drill or chuck:
1. Lock the tailstock in position, then unlock the quill.
2. Use the quill feed handwheel to extend the quill about
25mm (1”) out of the tailstock.
3. Insert an Mt#3 chuck arbor or drill bit into the quill just
until the tang drops into the slot and the tapers just touch.
Tip: For maximum locking of large diameter drill bits, push
and seat the drill bit into the quill with a clockwise rotation as
to load the tang against its slot.
4. Tap the end of the tooling or drill bit with a wooden block
or mallet to seat the tool.
5. Lock the quill.
To remove a tapered drill or chuck: Figure 32
Turn the handwheel counterclockwise until the arbor or drill bit is pushed out from the tailstock taper.
—if the tool is stuck in the bore and cannot be removed by turning the handwheel with moderate force, extend the
quill to expose the drift key slot, and use any standard drift key to remove the stuck tooling.
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 located on the control panel. Fluid
flow is controlled by a manual flow control valve
(see Figure
33).
NOTICE! Running the pump without adequate cutting fluid
in the reservoir may permanently damage 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.
Figure 33
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 cutting fluid pump
ON.
4. Adjust the flow of cutting fluid by using the flow valve.
Steady rest & follow rest
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.
