About Deburring
Deburring equipment is 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.
Burrs are often not acceptable, usually for safety reasons. These include hazards (slivers, cuts, etc.) that could occur from simply handling a part with a burr. Another reason is the potential damage of other materials that would come in contact with a burred surface. As an example, a piece of ductwork with a burr could easily cut into insulation or damage nearby electrical work. For this reason deburring equipment is used to remove burrs from a variety of manufactured parts.
R.T.&B Vibratory Deburring
In this batch-type operation, specially shaped pellets of media and the work pieces are placed into the tub of a vibratory tumbler. The tub and all of its contents are then vibrated. The vibratory action causes the media to rub against the work pieces which yield the desired result. Depending on the application this can be either a dry or wet process. The process is performed in an open tub so the operator can easily observe if the required finish has been obtained. Vibratory finishing systems tend to produce a smooth finish because the media essentially laps the parts. Since the load is moving as a unit, very fragile parts are quite safe in the vibrator. There is no tearing action or unequal forces that tend to bend and distort parts. This process has the advantage of being able to run numerous parts at once (depending on size).
R.T.&B. Barrel Burnishing
Barrel burnishing is a type deburring, the goal of which is to reduce minute irregularities and produce a clean, smooth surface. As the name implies, the parts are tumbled in a barrel shaped tub in one direction. The process produces a low pressure abrasion action by tumbling the parts against themselves or in a media to achieve this.
