Emergency stop (M). Push to stop all machine
functions. To restart, rotate E-stop button clockwise
until it disengages. Note: It is recommended that
start/stop button (N) be used for normal spindle
stoppage to prevent unnecessary wear on E-stop.
Spindle start/stop (N). Activates spindle rotation.
Spindle speed (O). Sets spindle rotation speed
within the pre-selected range.
8.2 Powerfeed operation
Turn machine OFF before
selecting speed and initial powerfeed settings.
Failure to comply may damage gear mechanism.
See Figures 8-1 and 8-2.
1. Turn off machine – spindle stopped.
2. Disengage spindle lock (C).
3. Select appropriate spindle speed range (D).
4. Select downfeed rate (F).
5. Loosen handle (A
2
) and rotate collar (A
1
)
counterclockwise to desired depth on scale.
OR… lower spindle to desired depth and set
collar (A
1
) to zero on scale.
6. Tighten handle (A
2
) to secure setting.
7. Loosen powerfeed disengagement knob (G).
8. Turn on spindle and adjust speed dial (O) to
desired RPM.
9. Pull downfeed handle (B) away from head to
activate power downfeed.
10. Once downfeed has reached pre-set depth, the
trip will release and spindle will retract.
11. To stop feed before cycle has ended, push
handle (B) toward head.
NOTE: Set downfeed dial (F) to “0” when not using
powerfeed.
8.3 Manual coarse feed
See Figures 8-1 and 8-2:
1. Turn off machine – spindle stopped.
2. Disengage spindle lock (C).
3. Set feed rate to “0” on dial (F).
4. Select spindle speed range (D).
5. Set drill depth (A
1
/A
2
).
6. Tighten powerfeed disengagement knob (G) to
prevent auto downfeed engagement.
7. Turn on spindle and adjust speed dial (O) to
desired RPM.
8. Engage workpiece using downfeed handle (B).
Feed will stop at preset depth.
8.4 Manual fine feed
See Figures 8-1 and 8-2:
1. Turn off machine – spindle stopped.
2. Disengage spindle lock (C).
3. Set feed rate to “0” on dial (F).
4. Select spindle speed range (D).
5. Set drill depth (A
1
/A
2
).
6. Turn on spindle and adjust speed dial (O) to
desired RPM.
7. Pull handle (B) into powerfeed position.
8. Turn fine feed handwheel (E) to accomplish
operation. Fine feed scale is 0.001 inch
graduations. If depth reaches pre-set stop, fine
feed will disengage and spindle will retract.
CAUTION: Downfeed handle (B) will rotate
during retraction.
NOTE: To disengage fine feed at any time during
operation, push handle (B) toward head.
8.5 Tapping procedure (45VSPFT
only)
Use one of the above methods to first bore the pilot
hole. IMPORTANT: Appropriate tap feed/speed is
determined by multiple factors, such as workpiece
material, drill size and type of tap. Consult a
machinist’s handbook or the tap manufacturer for
specific recommendations.
1. Turn off machine – spindle stopped. Insert tap
into chuck.
2. Disengage spindle lock (C).
3. Select tapping mode (K) and set feed rate (F) to
0.001.
4. Select low speed range (D).
5. Set depth scale (A
3
/A
4
) to desired stop. Make
sure scale ring system (A
1
/A
2
) has been set to
zero to prevent interference with downfeed.
6. Turn on spindle and adjust speed dial (O) to low
RPM.
7. Pull handles (B) into powerfeed position. When
tap reaches selected depth, spindle will reverse
and retract tap from hole.
8.6 Basic milling procedure
The Mill-Drill is provided with a face mill cutter with
tungsten carbide inserts. Install cutter onto mill
arbor, and secure with socket cap screw and washer
(N and O, Figure 5-1). Install arbor into spindle using
procedure in sect. 7.1.
For best results, all milling operations should be
performed with cutter raised as close to head
assembly as possible.
