FIGURE 8. MINIMUM FEED (LEFT) AND MAXIMUM FEED (RIGHT)
3.7.7 Stopping the feed
To quickly stop the boring head from feeding, pull the stop rod out of the torque hub
on the axial feed unit. This is helpful when cutting up to a shoulder.
3.8 Mounting the Electric Axial Feed Assembly
The electric feed unit consists of the adaptor plate, manual override, electric motor
assembly, and remote pendant control.
The axial feed unit can be mounted to either end of the boring bar. The locating nose
and hex nut hole of the feed unit fit into the locating nose seat and protruding hex
shaft of the boring bar end cap.
1. Mount the adapter plate to the end of the bar using the ¾-10 cap screw and two
½-13 cap screws.
2. Mount the mechanical override assembly to the adaptor plate. Make sure the hex
in the mechanical override is aligned with the hex on the lead screw.
3. Mount the electric axial feed assembly to the back of the mechanical override
with four cap screws.
4. Make sure to align the key way in the coupling.
5. Attach the pendant electrical cable to the rear of the electric axial feed.
