Figure 33. Example of a workpiece clamped in a
faceplate.
Faceplate
Non-Cylindrical
Workpiece
Clamp
To mount a non-concentric workpiece to a
faceplate:
1. DISCONNECT MACHINE FROM POWER!
2. Position appropriate device across bed ways
to protect them from any potential damage
from workpiece contact during installation.
3. With help from another person or holding
device to support workpiece, position it onto
faceplate and clamp it in place with a mini-
mum of three independent clamping devices
(see below for an example).
Be sure to take into account rotational and
cutting forces that will be applied to work-
piece when clamping it to faceplate. If neces-
sary, use counter-weights to balance assem-
bly and use a dial indicator to make sure
workpiece is properly positioned for your
operation.
Faceplate
Failure to properly secure workpiece to
faceplate could cause workpiece to be
thrown from lathe with deadly force. To
reduce this risk, use a minimum of THREE
independent clamping devices to hold
workpiece onto faceplate.
Machining non-concentric workpieces at
high speeds could cause workpiece to be
thrown from lathe with deadly force. To
reduce this risk, use a low RPM, and use
counter-weights to balance faceplate or
workpiece.
Refer to the prior
Chuck Installation subsection
for instructions on installing the faceplate.
The faceplate included with your lathe can be
used for a wide range of operations, including
machining non-concentric workpieces, straight
turning between centers, off-center turning, and
boring.
The tools needed for mounting a workpiece will
vary depending on the type of setup you have.
