Deburring Equipment Types and Terms
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.
Technically
any material that can be used to abrade another material. In industry
however, abrasives are
minerals from a select group of very hard minerals used to shape, finish,
polish or deburr another material. - Polishing method using a soft cloth and very fine polishing
compounds.
- Undesirable protrusions and metal edges that result from
machining operations.
- Often referred to as sandpaper. This is used
on machines such as disc sanders and is often used by hand. Often a synthetic
mineral is coated on the paper or fiber rather than actual sand.
- The texture of groups or masses of minerals is said to
be crystalline when distinct crystal faces are present.
- Refers to grinding machines and a process using
the face of a large wheel to produce flat and parallel surfaces
in high volume production.
- The intersection of two surfaces.
- A measurement of surface characteristics of a workpiece.
- A characteristic of abrasive grains that describes
their tendency to fracture or break apart then hit or placed under pressure.
- A natural abrasive that contains aluminum oxide and small
amounts of iron oxide. Once used extensively in the finishing industry,
it is used today mostly in home workshops for deburring by hand.
- A group of processes that use abrasives to remove
burrs or apply a finish to small workpieces.
- The abrasive pellets, stones or other materials used in
mass finishing and deburring. Examples are silicon carbide, ice, plastic,
sand and walnut shells.
- A process using very fine abrasive minerals for little
or no material removal. The step of finishing that often comes just after
deburring when needed. Surface appearance is the primary purpose of polishing.
- This synthetic mineral is one of the abrasives
used extensively in the finishing industry. It his harder than aluminum
oxides.
