4.4 Pre-startup checks
Do the following before operating the boring bar:
1. Tie down the RDU torque arms and the axial feed unit stop rod.
2. Use only properly sharpened tool bits.
3. Secure all machine parts, including the bearing assemblies, the tool carrier, and
the boring head. See that moving parts move freely.
4. Check that electric cords and cables are in good condition and correctly
connected.
5. Turn the hydraulic power unit OFF.
6. Check that the power unit wiring matches the electric source. Plug the power unit
into a grounded outlet.
7. Check that the reservoir level is filled above the red bar with UNAX AW32
hydraulic oil or equivalent.
8. Check that the power unit is set level.
9. Clean the hydraulic hoses and fittings before connecting them.
10. Check that the electric pump motor on the hydraulic power unit is turning as
indicated by the arrow on the case.
11. If using the boring bar in a vertical orientation, check that the two clamp collars
are in place to secure the bar (see Section 3.1 on page 15).
4.4.1 Running the machine
1. Set the feed direction and feed rate on the axial feed unit (see Section 3.7.1 on
page 27).
2. Press START on the hydraulic power unit pendant.
3. Adjust the bar rotation using the speed control hand wheel on the hydraulic power
unit or the knob on pendant.
4. As cutting begins, lubricate the work piece and cutting tool with plenty of cutting
oil. Apply cutting oil with a squirt can.
4.4.2 Stopping the machine
1. Press STOP on the pendant to stop the power unit.
2. After all parts of the machine have stopped, use a brush to remove chips.
3. If you will be machining the work piece again, see Section 4.4.4. If you are done
machining, see Section 4.5.
4.4.3 Repetitive machining
4. Reverse the boring head feed direction.
5. Manually or automatically feed the boring head back to where it started cutting.
