Description:

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:

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.

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.

Do not

attempt to do so as

5. A few drops of Water Aid in the pan will improve the cutting ability

of the Galaxy Wheels.

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.

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.

Use sufficient pressure to cause the surface of the wheel to
