BRAZED CUPS - FAQ
Over time I’ve noticed
some things using the brazing rods I’d like to pass on in hopes
of helping the folks out there braze their own cups. First off, I have
had varied success using the finer mesh sizes, as the diamonds tend to
clump up and make a resulting braze on the cup ring that resembles cornbread.
This is usually caused by having insuffient heat in the cup. The small
size of the diamonds makes them want to stick together. I’ve found
that this is also made worse by having the heat too hot from your torch.
Also, if you heat one specific spot too long the diamonds appear to loose
their coatings making the mixing of the diamonds with the melted matrix
difficult as the diamond tend to float to the top. One way I’ve
found to minimize this is to gently stir the melt with the end of my brazing
rod as I go around the cup ring. The stirring action appears to make a
more consistent mix on the cup ring by breaking up the little clumps.
I’ve found that it is difficult to get the torch heat just right
for a smooth braze surface on the very small mesh diamond rods. This has
only been true with the finer mesh sizes as the larger diamonds blend
very well with the hot, melted matrix. Too much heat and the diamonds
explode into little shooting stars (a little bit of this is not a problem).
If your cup isn’t hot enough when you start brazing the melt cools
too quickly and makes for a very rough braze surface. I have had some
success in improving the appearance of the finished braze by dipping the
end of the hot rod into a can of Technical Borax flux powder (30 mesh).
I only do this when it appears the diamonds are having trouble blending
into the melt. I use a table top electric stove (Single element) to preheat
my cups for about an hour before brazing.
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 consider.
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
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 diamond?
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 - Used to course(DR001) 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 (DR001)
`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
e. 220 mesh - Use as a medium smoothing step (DR002)
to remove scratches made by course (40/50, 50/60) mesh grinding if necessary.
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.
4. I have my own torch and have some existing worn-in cups. Can they
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
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
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 polishing?
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 pads and I like the results I'm getting.
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.
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.
Another problem I’ve encountered is a variation in the quality of
the steel cups I’ve tried to braze. Some of them appear to have
a component that interferes with the brazing process. I’ve noticed
this problem on cups made in China more so than those made in Thailand.
The problem presents itself with lots of holes in the matrix as if there
is a gas emitting from the steel. Cups should be clean and totally clean
from oil or grease before brazing them. I use a Craftsman 5415 D-1 Acetylene
and Oxygen torch and a neutral flame on my cup.
