103 Multi-Speed Brake Lathe
MACHINING DISC/ROTORS
MOUNTING TWIN CUTTER ASSEMBLY
1. The Twin Cutter Assembly with Dampener, is shipped assembled. Position
traverse slide to the extreme left (Figure 33) and the cross slide in toward the
spindle housing.
2. Before mounting the twin cutter assembly be sure the twin cutter arms are
positioned wide enough to straddle the disc rotor. (Figure 34) Mount the twin
cutter assembly to the slide using the stud, spacer block and flange nut (Figure
35). Select the hole that allows the cutters to be just inside the smallest diameter
to finish and still be reasonably square with the slide. Tighten flange nut just
enough to hold twin cutter assembly securely.
INSTALLING TWIN CUTTER BITS
Four Rotor Bits are included with the 103. Install 2 in Twin Cutter. The rotor bits have
three cutting edges -- make certain that the narrow side of the bit is on the top. This will allow for the proper
clearance angle while machining.
3. To install the rotor bits, loosen the clamp screw located on the underside of
the toolholder arms (Figure 36).
Install insert fully into the pocket machined in the toolholder. Tighten
clamp screw securely. (when installing inserts, be sure the pocket is clear
of any chips or debris).
SCRATCH CUTS
1. Using the cross slide, position the twin cutter assembly so that the tool bits
are about in the center of the rotor surface.
2. Start spindle and bring one of the tool bits into contact with the rotor face using the traverse slide. Once
contact has been made return traverse slide to original position. (Be sure twin cutter arms are secured with
clamp knobs).
3. Loosen arbor nut and rotate disc 180° being careful not to rotate adapters. Tighten arbor nut and make
another scratch cut as in step 2 above after moving cross slide position about .100".
4. If the first and the second scratch cuts are opposite with each other (180° apart)remove the rotor from the
arbor. Check the mounting adapters and arbor for nicks, burrs, or chips. Clean if necessary remount, and
run scratch test again.
