Frequently Asked Questions
We've listed out some common questions
about deburring media, equipment and compounds. These are common
questions, but keep in mind that the answers may vary for the
given application. If you would like clarification, please
contact us and we would be happy to conform our answers to
whatever details you provide us.
What are the differences between a bowl and a tub?
Because a bowl is round, it can have internal separation.
That means a method by which you can separate the media from the
parts after the process. A tub has the advantage of running
longer parts.
How does a centrifugal barrel machine work?
Centrifugal barrel starts by employing the theory of the
old-time tumblers. But putting it on a larger wheel and spinning
it at high speed while the barrel is tumbling makes it one of
the most efficient machines on the market.
Why do you insist centrifugal barrels function differently
than stated by those who manufacture them?
The manufacturer states that the media and the parts fall
from top to bottom as in an old-time tumbler. But because of the
high-speed spinning varies the centrifugal force, the parts in
meeting actually move vertically in a back and forth motion.
What is a centrifugal disk?
A bowl with a high-speed disk at the bottom for its base that
spins at high speed which the bowl remains stable, thus creating
a tornado effect.
What is a spin finisher?
Unlike all other machines, the media in a spin finisher
machine remains stationary and the part is fastened or chucked
and spun, then slowly dropped into the media.
Do magnetic finishes only work on aluminum parts, or are
they effective on stainless steel, gold, silver and other
non-ferrous materials?
They will work on any non-ferrous metal. However, they do not
work on parts that are magnetic.
When is ceramic media better than plastic and vice-versa?
Ceramic media is best when used with ferrous metal because of
its hardness and its weight. Plastic is best on non-ferrous
material because it wears, leaving a clean surface.
How long should the media last?
Ceramic media loses its ability to perform once its edges
have become rounded and its surface is glazed. Plastic media,
because of its rapid wear, never wears out but only gets
smaller, which can create a lodging problem and should be
separated.
What is meant by classifying my media and does this save
money?
Classifying media is to separate the media by use of
separating screens to keep the parts that have worn small from
becoming a lodging problem. This process is less expensive than
someone removing media that has become lodged.
Does all deburring require the use of water?
No. New media are being developed all the time to run in a
dry process. Ceramic media mixed with corn cob has been used for
many years where parts sticking together is a problem.
Of the many machines available, which would be best
suited for our parts?
Is it better to use a vibratory machine or a tumbler?
When is it best to use a centrifugal disk?
In what cases can a spin finisher be best?
Out of the hundreds of shapes and sizes of media
available, how do I select the right one?
How can I determine which media type is best?
How do I select the proper size and shape?

Below is a list of questions that, due to
their contextual nature, are unanswered. These are separated

Can I use one kind of compound for all jobs?
Is a filter system the best method?
For high polishing, is it best to use treated corn
cob or walnut shells?
What's the advantage of treated over adding the paste
yourself?
What are the various compounds or soaps?
