BRAZING - FAQ
1. I'm wondering about how many spheres can be ground before discarding
or refreshing the diamond.
Answer: It depends! There are many variables to
a. Hardness of the rocks
b. Size of the cups
c. Speed of cup rotation (I recommend between 120 and 200 RPM).
I have used this motor with good results: DAYTON 6Z084 AC Gearmotor,
124 rpm, TENV, 115V and Dayton 4Z613 (154RPM).
d. Tension on the cups
e. Mesh size and concentration of diamond in the matrix.
Experience so far has shown that in excess of 50 balls of varying
sizes at a minimum can be ground before renewal of course diamond
matrix is required using the diamond rods we sell. The fine mesh
cups last much longer.
2. Can you apply more diamond as the original brazing wears away
or do you have to toss the old brazed cups and replace them completely?
Answer: Once brazed, the cups can be renewed with
new diamond practically forever. The second brazed will meld and
blend with whatever is leftover from the first braze. The only thing
you have to "toss" is the grindings in the drip pan under
the cups. I recommend pre-heating your cups before brazing.
3.What diamond mesh size should I use as a roughing grade or should
I use a medium grade to try it out first before going completely
Answer: The rods come in a variety of mesh sizes
designed to meet standard lapidary techniques. Here is a list of
popular sizes and their uses:
a. 30/40 mesh - Used for course(DR001) grinding
of soft stones such as Marble, Onyx or Granite. Stones of 5 hardness
(Mohs) or less. The reason is that the harder stones will crack
and break the diamond bits out of the matrix. You must then re-sharpen
the cup using loose grit to expose more diamond.
b. 40/50 mesh - This is a good all around course(DR001)
grind compromise between speed of cutting and longevity of the cups.
Most Lapidary applications can use this mesh size.
c. 50/60 mesh - (DR001)Used to course
grind harder agates and Petrified Wood. Provides good longevity
of cups without excessive scoring of the stone. I've made about
70 spheres of varying sizes before re-brazing is required with this
mesh size dependent on the rock hardness.
d. 140/170 mesh - Use as a medium smoothing step (DR002)
`to remove scratches made by 30/40 mesh grinding if necessary. Use
this size to work Jasper that tends to flake and chip. Not needed
in most applications.
e. 220 mesh - Use as a medium smoothing step (DR002)
to remove scratches made by course (40/50, 50/60) mesh grinding
f. 600 mesh - This size will provide a semi-polish (pre-polish DR002)
before preceding to the final polish. Most of the time I've been
able to go directly from course grind to this mesh with great results.
It's amazing how much slurry is produced by the 600 mesh cups rotating
at 157 RPM. Be aware that the metal cups will scratch some stones.
I have converted to using Diamond pads now.
4. I have my own torch and have some existing worn-in cups. Can
they be brazed?
Answer: Yes! Standard brazing techniques are used
to apply the rod to the steel cups. A word of CAUTION!
Do not braze GALVANIZED cups without using the
proper breathing (Carbon Filtered) mask. Galvanized cups heated
with a torch produce toxic fumes. Try to remove as much of the galvanize
as possible before heating.
5. Do the grinding cups need to be beveled inside?
Answer: The cups will perform better and are easier
to adjust if beveled before brazing. I recommend a 22 degree angle
about 5/16's of an inch wide inside the cup. You can simply pre-grind
the cup using silicon carbide until you get the desired beveled
surface. Otherwise, visit your local Mill Shop.
6. How well do I have to make the weld on the cup?
Answer: The weld doesn't have to be pretty or even
smooth. The wear from the stone you are grinding will soon make
the surface very smooth. It will take several spheres of various
sizes to smooth out the weld from edge to edge. A deposit depth
of at least 1/8th inch is recommended.
7. How do I tell when to renew the diamond braze?
Answer: When you see the steel cup surface breaking
through the matrix it's time to re-braze the cup. In most cases
the bottom inside will wear through first (Point of most wear).
The cup will still grind on a larger sphere until you see the steel
underneath breaking through.
8. My cups seem to have stopped cutting. What's wrong?
Answer: Just as in the case of a dull diamond saw
blade, the cups will sometimes glaze over and new diamond needs
to be exposed. Simply apply a few shakes of silicon carbide of the
same mesh size as the cups to expose more (new) diamond. Once you
see the slurry return after the S/C has washed away you have applied
enough loose grit to sharpen the cups. This should not be necessary
very often. Another effective way of getting the cups to cut once
more is to put in a different sized ball. I've found that this helps
keep the wear more even as well. Be aware that diamonds never wear
out; they crack and break into little pieces and then fall out of
the matrix material. If you see a lot of empty holes on your cup
the diamonds have been shattered. This means you might be applying
too much pressure on the cups.
9. How much water should I use on the sphere during grinding and
Answer: You need to keep a steady drip on the sphere
during grinding to flush out the loose particles during the grinding
phase. If the sphere is covered with slurry then you need to increase
the drip just a bit. When polishing I start out with a light drip
on the sphere using Velcro diamond pads and adapters (see above)
or cut pieces inside of PVC pipe cups. After the spots are gone,
I start with 200 or 300 mesh advancing to 500 , 1000, 1500 for about
20 minutes each step and then 3000. After a half hour the sphere
should have a bright polish at 3000 mesh pads. You can go higher
in mesh size but the result is sometimes hard to see any improvement
in the shine. I''ve been experimenting with 8000 mesh & DF pads
and I like the results I'm getting. I have found that pads labeled
DF provide a superior shine on any sphere.
10. How many rods will it take to braze my cups?
Answer: It depends on the cup size and depth of
weld deposit. I generally put 1/8th inch deep welds on approximately
5/16th inch wide beveled cups which takes 1 rod per cup for 1 ¼
inch cups. It takes about 1.25 to 1.5 rods to braze each 2 inch
cup but you can go a little thinner on the depth and stretch it
out. The rods are 15 inches long for all mesh sizes. Please call
(see the "About Us" tab on the Home Page) if you have
more questions concerning the brazing process. The size I'm referring
to is the pipe size number stamped on the reducer.
11. Why does the cup wear through in just one spot (usually near
the bottom of the circle)?
Answer: Unless you grind several different size
spheres over time the abrasive diamond matrix will be depleted in
a single spot on the cup ring. A small sphere size relative to the
cup size will wear on the inner part of the cup were as a larger
sphere size will wear on the outer ring of the cup. Even though
the matrix has worn through in a particular spot, the cup will still
work on a different sized sphere.
12. I have been xperimenting with JB Weld
epoxy to attach Core Bit segments and my results are not that good.
It works pretty well on smooth rocks but they become detached if
the sphere has points or uneven surfaces. I've decided it is not
reliable enough to use on a commercial basis; Therefore all my cups
made for customers will be bronze welded.
