Care of Arbors and Adapters
Although the adapters, arbors, and the spindle are
made of top grade steel and are turned, hardened,
and precision ground to close tolerances, great care
should be taken in their use, handling, and storage.
Even the smallest nick, scratch, or loose chip can
cause incorrect rotor alignment, resulting in inaccu-
rate machining.
Remove all adapters from the arbor after machining a rotor and
wipe them clean - especially the inboard adapter. When a fin-
ished rotor is removed from the arbor, the inboard adapter may
move slightly away from the face of the arbor and allow metal
chips to fall into the opening causing a poor mounting for the
next rotor.
Regularly inspect the faces and seating tapers of the adapters
for nicks and scratches, correct any flaw with a fine stone. If the
damage cannot be corrected, replace the adapter. Handle the
adapters and arbors with care and store them on individual
hooks. DO NOT throw them into a box. The adapters are
designed for mounting rotors only, DO NOT misuse the
adapters.
