12. If mounting the leadscrew away from the RDU, weld the tack weld block
to a fixed object and screw the leadscrew into it. Secure the leadscrew by
tightening the jam nut snug against the face of the tack weld block.
13. Position the AFU and bar to achieve the required feed distance and to place
a tooling hole in the correct position for machining.
14. Tighten the axial feed clamp collar screws to fasten the collar to the bar.
3.4 AXIAL FEED
3.4.1 Selecting the feed direction
The feed direction has three positions:
•Forward
• Neutral
• Reverse
Pushing the three-position feed shaft in on one side or the other will feed in the
direction indicated by the arrow on that side of the body. Check that the engage-
ment pins are fully engaged. The neutral (middle) position is for no feed.
A shaft under load may require a firm bump to disengage.
If the axial feed box fails to feed the tool head, check the shear pins. Replacement
pins are included with the AFU. To replace a pin, see Section 5.3.1 on page 59.
CAUTION
Feeding the bar into a fixed object could damage the internal feed
clutches.
