damages the bond and can cause the premature
loss of diamond particles.
||Use a full flood
coolant directed where the wheel contacts the
carbide tip. It might be more convenient to grind dry, but
studies have shown that wheel life can be increased by more
than 100 percent by grinding with a flood coolant.
Excessive Feed Rates

anywhere in the operation causes pounding, which
reduces the life of the diamond wheel and produces a
poor surface finish on the tip.
||The saw plate
should be supported firmly by clamps that are
operating correctly and set close to the tip.
||Clean all dirt
from the wheel mount. Check the mount for any
nicks or damage that will cause run out, and use flanges
that are at least 1/3 of the wheel diameter.
||In order to
reduce vibration, place your grinder on the most
solid floor possible and bolt down.
& Braze Contact
||Keep the amount
of steel ground by your diamond wheel to
an absolute minimum. Steel causes diamond pullout, which
results in higher wheel wear. Brazing materials load the
wheel surface, causing excessive heat generation.
used with flood coolant grind most efficiently
at a minimum of 5000 SFPM (surface feet per minute)
to maximum of 6000 SFPM. Used dry, the minimum/maximum
SFPM rates are 2500 to 3000.
