Polishing
Steps: |
| 1 |
Cut or shape
material to the desired surface or pattern using either a
diamond blade or diamond cup wheel. |
| 2 |
Using a
clamping device, secure material to be polished to a proper work
surface. |
| 3 |
Remember,
polishing is a process which takes time and requires that each
grit size pad be used properly to achieve a quality finish. |
| 4 |
Using the 30,
50, 120, or 220 coarse grit pads, remove all rough scratches and
cut marks. Smooth the surface as much as possible with these
specific grit pads. The smoothing of the surface during this
stage of polishing will determine the quality of the finish that
will be achieved. After working the area, dry the surface to
determine if all large scratches have been removed. Using a
lumber crayon or pencil, mark the surface to determine the depth
of the scratches remaining. |
| 5 |
Once all
large scratches have been sufficiently removed, the finer grit
pads can be used to achieve the quality finish. The fine grit
pads consist of 400, 800, 1800, 3500. If more luster or color
from the polished surface is desired, use the extremely fine
8,500 and13,000 grit pads. |
|
| After completing
the polishing process, the following steps must be followed if a mirror
finish is desired: |
| • |
Make a paste of cerium, aluminum
or tin oxide using water. |
| • |
Apply paste to felt wheel. |
| • |
Run felt wheel with slight
pressure against the surface to generate heat. |
| • |
After paste dries, polishing is
complete. |
| • |
Wash surface with water and dry. |
|
| The surface should
have a high luster or finish. If the surface appears to have small
scratches, repeat step 5.
In some cases it may be necessary
to repeat steps 4 & 5. |
| Important
Points in the Polishing Process: |
| • |
Barranca Diamond polishing pads
are designed to be used solely with water to minimize the wear
on the pads and prevent hazardous dust. (The use of water acts
to cool the polishing pad material, flush away grindings, and
eliminate hazardous dust). Always wear eye protection at all
times. |
| • |
Never skip grit sizes during the
polishing process. Skipping grit sizes will result in an
unsatisfactory finish to the stone. |
| • |
Diamond polishing pads wear out
prematurely due to overworking of the material or by not using a
sufficient amount of water. |
| • |
Failure to spend adequate time
polishing with each grit size pad will result in an
unsatisfactory finish. |
| • |
Selection of the flexible rubber
backer pad for shaping and curved work is highly recommended.
Use the rigid backer pad for the straight edge and flat face
material. |
| • |
Flat 4" 100 mesh wheel can be
used to plane down uneven surfaces, remove stubborn scratches
and knock off saw nubs. |
