How to Determine the Machine
System You Need.
Capacity Specification Chart shown
indicates the capacity of the machine system, which is primarily
determined by bowl size. Fill capacity is shown in liquid and
pounds of media. Normal deburring and burnishing operations are done
with perform media shapes which varies in density and weight.
Ceramic media weights approximately 100 to 120 pounds per cubic
foot; whereas, steel burnishing media weights around 300 pounds per
cubic foot. Not shown is plastic media which normal weights from 55
to 85 pounds and dry organic media from 25 to 35 pounds per cubic
foot.
For the best and fastest processing
results, all bowls should be run 2/3rds to 3/4 full of media. The
greater the amount of media or weight you can get in the machine the
faster it works. As a rough guideline, the capacity of parts
that can go into our equipment can be determined in a number of ways
as follows:
Weight
For deburring purposes, use 50 to 60%
media to parts by weight. That is, if the 1 cubic foot machine takes
100 pounds of media, you can normally add 40 to 50 pounds of parts
to that same machine system
For polishing purposes, use 80 to 90%
media to parts by weight. Based upon 1 cubic foot machine that
equals 10 to 20 pounds of parts.
Volume
Nova 1000 series or a 1 cubic foot
machine system can process the amount of parts you can fit into a
box 12” x 12” x 12”.
Nova 500 series or a 1/2 cubic foot
machine system can process the amount of parts you can get into a
box 6” x 6” x 6”.
Nova 250 series or a 1/4 cubic foot
machine system can process the amount of parts you can get into a
box 3” x 3” x 3”.
Size
First, there is no restriction as to
the smallest part you can work in our equipment. The problem is
locating these parts and getting a media small enough to allow the
parts to be separated out of media. The smallest parts capable of
being processed and separated by our patented screen system is .030
in size.
The largest size part(s) that will go
into a machine system that will be worked properly or uniformly is
determined by the bowl’s channel width or “B” dimension. That is, a
part will move in an equal x y and z motion. Parts larger than that
dimension can be worked in any bowl, equal to “C” dimension;
however, they will be touching either the inside or outside walls of
the bowl and may not rotate properly. The largest size part is a
function or cord length of the inside cone and outside wall
diameters.

Nova Finishing Systems Inc., manufactures small, heavy-duty bowl
finishers that stack up to most of the big equipment on the market,
but cost much less. Nova series vibratory equipment also comes with
the same warranties of the larger machines. Form more information
