Label the specimen with your name so that it can be easily identified.
2. Turn the Motor On, then the water, adjust the flow to obtain a good film of water. Too much water will
cause a spray when it contacts the sample.
3. Beginning with the 120 grit belt and using both hands to hold the specimen, carefully place the
sample face onto the exposed area of the belt being careful not to contact the rotating surface with a
sharp edge of the specimen or your hand.
4. Applying moderate pressure evenly, move the sample left-and-right across the belt surface to obtain
uniform grinding. Use both hands to hold the specimen; unsecured specimens can "Catch an Edge
and FLY"!
5. Lift the sample from the wheel periodically to determine the progress of grinding but do not rotate the
sample. The 120 grit stage is complete when all the lines scratched in by the grinder are parallel on
the specimen surface. If any line or scratch is not in the same direction as the other lines, continue
grinding until all of the lines are parallel.
6. When all of the sample's scratches are parallel, carefully wash all of the debris from sample using tap
water and dry the specimen immediately using a paper towel or pressurized air to avoid corrosion.
7. Proceed to the 180 grit stage with the scratches oriented approximately perpendicular to the intended
grinding direction and repeat steps 3 thorugh 6.
8. When the 180 grit stage is complete, you're ready to move on to the medium/fine gri
