GRINDING AND POLISHING

STEP 1: ROUGH SHAPING

The 180# diamond lap disc is used for shaping

rough material and removes any surface

irregularities. This allows your work piece to be

smoothed and polished. Never use discs dry

and use only clean water as a lubricant. Do not

use wipers or sponges, as they may become

contaminated with cutting debris and larger

diamond particles, causing scratches in your work

piece. Grind the edges of stones and glass to fit

your desired mounting or template. Remove as

many flat spots as possible if you are making a

180# diamond lap disc

domed cabochon. If a sharp edge is present on

your work piece, gently apply the sharp edge to

the diamond disc to prevent possible chipping.

STEP 2: SMOOTHING

The 325# brown diamond smoothing disc is

used next to further refine your desired shape. It

also removes scratches and flat spots left from

the 180# rough grinding process. It is important

to remove all of the scratches from step 1

because these scratches are difficult, sometimes

impossible, to remove later in the smoothing and

polishing process. Rinse the black spray shield

with clean water before proceeding to step 3.

STEP 3: SMOOTHING

The 600# red diamond smoothing disc is used

next to further smooth and refine your work piece

before proceeding to the next step. It is not as

aggressive as the last disc and aids in removing

the remaining scratches and flat spots. Remove

any scratches left from step 2.
