About Deburring Machinery
Deburring equipment and custom finishing deburring
machines are used for the removal of burrs that result from machining
operations on metal and plastic parts. Burrs are undesirable protrusions
that occur on the surface of a manufactured piece. There is a wide range
of custom finishing deburring
machines and deburring equipment used in the industry. Barrel and
vibratory tumblers are
used for deburring mass numbers of parts.
Abrasive brushes and grinders can be used to deburr one surface side at a time
in large quantities on a conveyer belt system. For parts that already have a
finish on them, mass styles of deburring are not used as the finish would be
removed along with the burr. So items like sandpaper, files and hand grinders
can be used to remove isolated burrs individually, this is usually done by hand.
Burrs are often not acceptable usually for safety reasons. These include hazards
that could occur from simply handling a part with a burr. Another is the potential
damage of other materials that would come into contact with a burred surface.
A piece of ductwork with a burr could easily cut into insulation or damage nearby
electrical work. For this reason, deburring equipment is widely used throughout
a range of manufacturing industries.
There are several types of custom finishing deburring machines, including polishing
equipment and tumblers. Polishing
equipment is used in many types of deburring in order to finish and smooth
a product. The polishing process usually involves fine deburring media that does
not remove much material, but rather enhances surface
appearance.

Types of Deburring Machinery
- is a process that
produces a low-pressure abrasion action by tumbling work pieces in
a hexagonal or octagonal barrel together with an abrasive media.
- machines are essentially barrel machines and the name describes
the spinning disc at the bottom of the machine that spins
the part and abrasive media together.
- is able to process high volume parts
on a constant basis through in-line production.
- remove burrs from metal and plastic parts.
- are versatile machines
that can be set up for either continuous processing or batch processing
for extended time
cycles.
- is used in many types of deburring. Examples
range from the barrel or vibratory tumbler as well as non-enclosed
options
like Nylon Abrasive Filament (NAF) brushes or standard hand held sandpapers
and filers.
- is
also a type of deburring machinery which produces a desired effect.
Rather than the metal part being immersed
in polishing media, as in the case of vibratory or barrel tumblers,
the part surface is blasted from the outside by the appropriate media
which is often small ceramic pieces or even walnut shells in the case
of softer plastic parts. see Sand Blast Equipment
- is the abrasive material used in deburring.
- is the burr removal process in which an appropriate
number of parts, depending on part size and abrasive material, is
accelerated and decelerated by mechanical means inside of a drum-like
enclosure.
- are one type of deburring
machinary. Often similar in shape and technology as the barrel machines,
but are open at
the top allowing the ability to view the progress of the deburring
without
stopping the machine.
