1. Learn about the control panel shown on Page
16 and the controls shown in Figure 16.
2. Clamp the workpiece to the milling table, and
adjust the headstock to the needed h
eight,
depth of cut, and milling
path.
Note
: For special milling operations, loosen
the headstock tilt lock nuts and rotate the
headstock to the needed angle (
Figure 17).
Note:
If you are only milling in one direction,
lock the
unused table slide in place.
3. Refer to Choosing Spindle RPM on Page
19 to find the best spindle RPM, and then
move the headstock levers to the appropriate
spindle speed positions.
4. Unlock the headstock levers (Figure 18), and
use th
e lift motor to position the headstock
close to the workpiece
.
Note
: For maximum spindle rigidity while
milling, keep the spindle retracted into the
headstock as far as possible with the quill
headstock lock levers locked and the fine
feed lock knob tightened.
—For milling tighten the fine feed lock knob
and use the fine feed handwheel and its
scale to set the milling depth. Then lock
the
quill lock lever.
—For drilling, leave the fine feed lock knob
loose, and use the quill feed lever handles
to draw the quill and drill bit down.
5. Push the green power button.
6. Turn the rotary switch dial to F or R to select
the appropriate cutting direction for the type
of cutter that you are using.
7. Use the table handwheels or the power feed
to move the table so the cutter enters the
workpiece slowly. Refer to the power feed
manual for power feed operation if required.
