OPERATION
COLLET SHAFT
Your grinder is equipped with a collet shaft to
receive 12" diameter mandrels. A collet reducer is
supplied which, when used with this collet shaft,
wiil receive 1/8" diameter mandrels. There is also a
collet reducer for 3/16" diameter mandrels available
as a replacement part. See illustration on page 6.
GRINDING WHEELS AND ROTARY FILES
Maximum diameter grinding wheeis with 1/4"
mandrel is 11/2" and maximum diameter for rotary
files with 1/q" mandrel is 3/8".
Use grinding wheels when working with hard
materials and rotary files for milling soft materials
such as nonferrous metals (aluminum, brass,
copper, etc.). Using grinding wheels when working
with soft materials will load up the wheel and will
not allow wheel to cut as it was designed.
TO ATTACH WHEEL OR FILE TO GRINDER
Disconnect Grinder lrom power supply.
Press in collet shaft locking pin, Key No. 5 (See
parts list, page 7)io hold collet shaft. lnsert mandrel
into collet shaft as far as possible in order to provide
a minimum overhang. Tighten collet nut securely. A
minimum overhang will insure less vibration and
better results. Wheels and points should be trued
each time they are used to insure cutting and
balance. Dress the mounted wheels and points with
a dressing stone.
See chart below to determine proper wheel diameter
and thickness.
