5.4 Automatic down-feed
Automatic down-feed is feature for use only while drilling.
The down-feed rate changes can only be made while
machine is running and is in drilling mode. Rate of the
automatic spindle down-feed (Fig. 8) is equal to A: 0.2, B:
0.05, and C: 0.1.
1. Check for drilling mode (H, Fig.1).
2. Start machine. Press start button (A, Fig. 1).
3. Set the down-feed rate. Use the handle (L, Fig. 8) to
change the rates.
* Rate changes (Fig. 8) can be made while machine
is running and in drilling mode (H, Fig. 1).
3. Set the depth stop. Use the side ring scale depth
stop. Refer to
Setting the Depth Stop (5.2)
.
* Only the ring scale will disengage the automatic
down-feed and return the drill to starting height.
4. Release the front side depth stop. Loosen the lock
handle (M, Fig. 7). This depth stop must be free to
allow ring scale depth stop to work properly.
5. Release the down-feed lever lock. Turn the handle
(N, Fig. 9) about 7 times.
6. Change the auto down-feed mode. Pull the handle
outward to select automatic down-feed. Refer to
(Fig.9).
Note: Setting the scale ring’s depth stop will disengage the
automatic down-feed when the zero setting is
reached. The down-feed lever will transfer to manual
mode and return the drill to starting height.
5.5 Using the micro-feed hand wheel
The micro-feed hand wheel is capable of slow and accurate
movement of the drilling tool. It also has an anti-spin feature
for times when the micro-feed hand wheel will not be used.
Pull out the knob (Z, Fig. 7) to disengage the micro-feed
hand wheel during auto down-feed and non use. Micro-feed
hand wheel operates in automatic mode with down-feed rate
set to zero.
1. Adjust the rate of spindle down-feed to “0”. Use the
handle (L, Fig. 8).
3. Set the tool depth to zero. Lower the tip of the bit to
the top of the workpiece (Fig. V).
4. Adjust the down-feed levers to automatic down-feed
mode. Pull down-feed handle (N, Fig. 9) to the
automatic position.
4. Release the micro-feed hand wheel’s depth ring.
Loosen the thumbscrew (X, Fig. 7).
5. Set the scale to zero. Adjust the depth ring (Y, Fig.
7) to zero.
6. Lock the depth ring. Tighten the thumbscrew (X, Fig.
7).
7. Push-in the micro-feed handle (Z, Fig.7) to engage
the hand wheel.
8. Turn the micro-feed hand (Z, Fig. 7) clockwise to
lower the spindle.
