16 OPERATION INFORMATION
2.4 Optional Extended Cutting Head
Kit 20-3092-1 or 20-3345-1
Installation
1. Install locks, but do not tighten. Open cutters as far
as possible and clean with parts cleaner/solvent to
remove the protective coating applied for shipping.
Lock the end cutter. Close the cutters and clean.
Lock the inside cutter, loosen the end cutter, rotate
and clean.
2. Install the insert-holders into the toolholders. Verify
the insert holders are flush with the inner edge of the
toolholder before tightening the toolholder screws.
Pay attention to the difference in the depth that the
two holders are installed on the twin-cutters. The pic -
ture below shows the recommended installation. This
set up has a maximum rotor thickness at the edge of
approximately three inches (76 mm). It is recom -
mended to work best for the majority of rotors, how -
ever the insert-holders may be reversed if necessary
to machine larger width rotors.
3. Install the micro-round inserts, using the small torx
wrench.
4. Remove the screws securing the small backing plate
on the end of the extended cutting head’s shaft using
the enclosed T-handle 5mm Allen wrench.

5. Loosen the tool holder shaft locking bolt with 6mm
Allen Head wrench. Carefully remove standard twin
cutter from the ACE-model lathe.

ing rivet.
