2.
Determine the final diameter, in inches, for
the cut you are about to take.
Note:
For this step you will need to aver-
age out the diameters or work with the finish
diameter for your calculations.
3.
Use the following formula to determine the
needed RPM for your operation:
With the calculated RPM, let us say it needs
to be 80 RPM
.
So the headstock levers must
be moved to the appropriate
X
or
Y
and
H
or
L
positions.
Note:
You may need to rotate the spindle by
hand or use the jog button to get the levers to
properly engage.
4.
Move the spindle speed dial so the red dia-
mond on the dial lines up with the red dia-
mond point on the headstock. Both diamonds
should be at the 12:00 O'clock position
(
Figure 43
). The RPMs available now are
low: 25, 80; and high: 235, 700.
5.
Move the spindle range lever to
L
(Low
Range) as shown in
Figure 42
. The RPMs
available now are low: 25, 80.
6.
Move the range splitting lever to
X
as shown
in
Figure 42
. The final spindle RPMs is 80.
Setting Spindle RPM
To find and set the spindle RPM:
1.
Use the table in
Figure 41
to determine the
cutting speed for your workpiece.

Note:
For carbide cutting tools, double the cut-

Refer to the MACHINERY'S HANDBOOK for
more detailed information.

tools.
Failure to follow RPM and feed rate guide-
lines may threaten operator safety from
ejected parts or broken tools.
The spindle speed dial positions the headstock
gears in one of three speed modes. In each
mode, there are two speeds in low range and two
speeds in high range. The range lever selects
high or low range, and the range splitting lever
selects one of the two remaining speeds within
that range.
The range lever is used to select a set of high
or low range spindle speeds from one of the
three spindle speed modes shown on the spindle
speed dial.
The range splitting lever is used to select the final
spindle speed from the set of high or low range
speeds selected by the range lever.
