3M abrasive prds for engine manufacturing applications User Manual

For the many stationary and rotating components of
an engine, you can select an advanced abrasive prod-
uct most appropriate for your quality and production
requirements.  These include performance-proven 
3M coated abrasives, 3M

™

Scotch-Brite

non-woven

abrasives and 3M micro abrasives and superabrasives.  

3M has the broadest selection available of coated
abrasive types and grades for rapid gate removal and
grinding of jet blade vanes, rotors and blades.

With Scotch-Brite non-woven abrasive wheels and
belts, controlled abrasive action helps prevent under-

cutting or gouging for less chance of affecting critical
tolerances. The wide product range allows you to vary
abrasive aggressiveness and conformability to meet
surface finish requirements.

Fresh abrasive is continually exposed to the work 
surface for consistent finishes on jet blades, shaft and
hub surfaces, tubing, nacelles, and more.

The 3M TC 330 roto-peen flap assembly consists of
shot bonded to a flexible flap.  To straighten and 
balance shafts, the flap is rotated at high speed so the
shot strikes the component with each revolution.  This
is cleaner and more precise than loose shot “blasting.”
