The face plate supplied with the model G9729
Lathe/Mill can be easily mounted to the spindle
once the chuck has been removed. Installing the
faceplate follows the same steps as an
y of the
lathe chucks. I
n Figure 15 the face plate is being
set up to hold a workpiece for precision boring.
Always use a minimum of 3 independent clamps
when holding eccentric workpieces.

Figure 15. Setting up face plate.
To load a workpiece:
1. Unplug the lathe/mill!
2. Support the workpiece.
3. Lock the tailstock and then turn the tailstock
quill
so the dead center makes contact with
the centerpoint of your workpiece.
4. Lock the tailstock and apply sufficient pressure
to
hold the workpiece in place. Depending on
the workpiece, some additional support may
be needed.
5. Secure the workpiece with a minimum of
three
independent clamping devices. Failure
to follow this step may lead to deadly injury
to yourself or bystanders. Take into account
rotation and the cutting forces applied to the
workpiece when clamping to the faceplate.
Make sure your clamping application will
not fail!
Failure to provide adequate clamping will
cause workpiece to eject causing serious
injury or death to operator or bystand-
ers. Use
a minimum of three independent
clamping devices when turning eccentric
workpieces.
Thrown workpieces or
chuck keys can cause
serious injury or death to
the operator or bystand-
ers. Securely
clamp your
workpiece and remove
the chuck key before
turning lathe ON!
6. Check your centerline, as tightening the
clamps may have caused it to move. Adjust
as necessary.
7. Use a lower RPM when machining heavy
eccentric workpieces. Take into consider-
ation
workpiece size and material.
