Galaxy metal-bond diamond grinding wheels are designed to
provide the gem-cutter with a smooth, fast cutting, true-running grinding
surface ideal for working stones. The diamonds in a Galaxy Wheel are
held on a heavy steel ring by an extremely hard nickel alloy plating. The
ring is mounted on a tough, glass-filled polyester core, making a
smooth, quiet running wheel.
Use and Maintenance:
Galaxy Wheels never need dressing.
you may damage or ruin the wheel.
For longer wheel life and to prevent wheel damage, the following
practices should be followed when using your Galaxy Wheels:
1.
Use a light to medium pressure when grinding stones. Although
diamonds are extremely hard, they are also quite brittle and can be
easily shattered by excessive pressure or the bumping of a heavy
rock. The wheels cut most effectively with a light to medium
pressure and will last longer as well.
2. Use a steady rest to avoid uneven wear patterns. Steadying your
hand while grinding will help prevent bumping and chattering that
causes uneven wear of wheels. It will also help prevent damage to
stones.
3.
Use a coolant while grinding. Water is best and a small amount will
normally do to keep the wheels wet. This prevents the formation of
rock dust, keeps your stone cool, and stops the buildup of rock
residue on the wheel surface which can slow down cutting action.
When grinding soft materials such as onyx or turquoise you can
place both geysers under the same wheel as more water is needed
in order to keep the wheel clean.
4. Use the entire surface of the wheel as you grind your stone. Avoid
using just the center or edge or any one area of the wheel surface
as this will cause excessive wear in that area and shorten the
effective life of the wheel. When grinding crosses, hearts, fire
agate, etc. be certain you grind with the diamond covered surface,
not on the bare metal side of the wheel, as this will undermine the
diamonds and cause excessive wear of the wheel edge.

5. A few drops of Water Aid in the pan will improve the cutting ability
of the Galaxy Wheels.
6.
Reverse the wheels occasionally so that the diamonds cut from the
opposite direction. The edges of the diamonds will wear with use,
and the cutting speed will decrease. By reversing the wheel, the
cutting edges of the diamonds are renewed. (The 80 and 220 grit
wheels will be interchanged when you reverse the direction of the
two wheels.) See instructions for "Remounting and balancing
Galaxy Wheels" when reversing them.
Nova Resin-Bond Diamond
Sanding and Polishing Wheels
Description:
Nova Wheels are specially designed to produce an excellent finish
on stones with a minimum of time and effort. The diamonds in Novas
are embedded within a tough, flexible, plastic resin backed by an extra
soft, thick, sponge rubber backing. This soft, flexible construction
enables the surface of the Nova Wheel to conform to the stone,
eliminating flat spots and scratches.
Use and Maintenance:
1. Nova wheels
must
be used with a water lubricant. This fact cannot
be stressed too strongly, for if the wheels are run dry for more than
a few moments, rapid wear and damage can result. Make certain
that the geyser is supplying sufficient water to the Nova Wheel
before using it, and remember to move the geyser to the next wheel
as you progress through the sanding and polishing procedure.
2.
Nova Wheels should be broken in by sanding and polishing a large
agate cab prior to working on others. This is necessary in order to
remove excess resin coating surfaces of the diamonds. Spend from
two to five minutes on each wheel with the first cab, working it over
the entire surface of the wheel. The finer grit wheels, especially the
3000 grit wheel and 14000 grit disc, will take longer to remove the
excess resin, and will continue to improve in speed and finish as
more stones are worked.
3.
Use sufficient pressure to cause the surface of the wheel to
