Figure 14 Cut Depth Micrometer
TURNING A ROTOR
18) When the cutting tools have moved
outward beyond the edge of the rotor,
press the bottom (OUTFEED) of the
Feed Direction Switch on the lathe to
place the switch in the OFF position.
19) Momentarily turn off the Drive Motor
and check the surface of the rotor. It
should have a rough cut surface across
the entire face on both sides. If not,
make another rough cut, otherwise
proceed to the next step for a finish
cut.
20) Turn both Cut Depth Micro-meters
clockwise one small division to move
the cutting tool tips towards the face
of the rotor by 0.002 in. Figure 14
illustrates that 0.002 in. is the distance
between two of the closest marks.
21) Turn the Feed Rate Switch on the
Drive Motor Control to 2 (slow feed).
22) Press the top (INFEED) of the Feed
Direction Switch on the lathe. The
lathe cutting tools will automatically
feed inward making a finish cut on the
rotor. The cutting tools will
automatically stop at the setting
determined in Step 13 by setting the
Auto Infeed Stop button.
One rough cut and one finish cut are
normally sufficient for most applications. If
not, repeat rough and/or finish cuts as
required.
When a satisfactory surface finish has been obtained, press the
Safety Lock and move the AUTO/MAN Shift to MANUAL.
Back the cutting tool tips away from the rotor by turning the Cut
Depth Micrometers counter-clockwise.
Use the handwheel to back the cutting tools to a position beyond the
outer edge of the rotor.
Remove the Lathe and repeat the operation on the other side of the
vehicle.
