"An hour's work in 45 minutes"
f . JOHN uses a Rotor sander in finishing motor car body
(grinding the weld on a fender on a headlight flair intersection in a auto factory in 1929)
x! ^ parts. "The job's got to be good," says he. "And you don't have to baby this machine. It keeps on
going all day long and it's easy to handle."
" The Rotor sander weighs only 10% pounds, and its vibrationless power and high speed cutting qualities
mean much to the workmen's pay envelopes. They can do more work per hour with a Rotor sander-25%
more
easily!
Ask for the new Rotor Catalog. It tells "why" and "how."

Precision Grinding ( probably the camshaft of a Liberty 12 or
a straight 6 aero engine)
BY finishing two clearance diameters of these water cooled air craft camshafts at one grinding operation, the
grinding time is cut in half — another interesting application of a Cincinnati Grinder in the aeroplane industry.
A high finish and extreme accuracy are obtained on this job which is handled by a Cincinnati 14-in. x 36-in.
Plain Self - Contained Grinder. Duplex wheels allow two clearance diameters to be ground simultaneously.
The two steady rests as illustrated provide ample rigidity to give the desired accuracy.
Among the improved features which make the Cincinnati Self - Contained Grinder so profitable and accurate
on grinding operations include: the continuous force feed lubrication to [the table ways, texrope drive to the
grinding wheel spindle, improved type quickly operated steady rests, friction clutch in the table drive, long
bearing foot-stock and centralized operating control.
Send in samples of your grinding jobs and let us make estimates for you. It is well to remember that
