GRINDING WHEELS
WARNING: THE USE OF ACCESSORIES AND ATTACHMENTS NOT RECOMMENDED BY DELTA MAY
RESULT IN RISK OF INJURIES. Grinding wheels used with this grinder should be rated for 3600 RPM or higher and
be 8" in diameter with a 1/2" arbor hole.
Two aluminum oxide grinding wheels are supplied with your grinder: one 36 grit and one 60 grit. For best grinding
results, and to maintain good balance, always keep the wheels properly dressed. Do not force the work against a cold
wheel. The grinding wheel should always be run at idle speed for one full minute before applying work. It is recom-
mended that only balanced wheels be used with your grinder. The use of balanced wheels adds years to the life of the
bearings on the grinder and by eliminating the most common source of vibration, more accurate work is accomplished.
DRESSING A
GRINDING WHEEL
When dressing a grinding wheel, use a suitable silicone
carbide stick type dresser, as shown in Fig. 15. Bring the
dresser forward on the tool rest until it just touches the
high point on the face of the wheel and dress the wheel
by moving the dresser back and forth. Repeat this oper-
ation until the face of the grinding wheel is clean and the
corners of the wheels are square.
