Deburring Machinery

Deburring is the industrial process of removing burrs, protrusions, jagged edges, slits and other imperfections that are formed at the edges of a metal object’s surface. Deburring is also used for plastics, rubber extruded and molded parts to remove the flash and extra materials. Deburring also takes place on materials such as steel, aluminum, zinc, brass, cast iron, copper, gold, silver, titanium, and nickel alloys, etc. Before the component goes onto the next stage, it is very important the burrs be removed because the loose burr may become stuck in other components. Additionally, a sharp burr can cut an operators hand, so it is also a safety issue as well as a manufacturing and visual appearance issue.

Deburring is often referred to as polishing and while it can be performed by hand in many instances deburring machinery gives you quicker processing times and more reliability. Deburring machinery is very useful for small castings, surface finishing, precision stampings, forging and better overall finish of a product. These machines are made for light deburring, polishing, and cleaning small, light precision parts etc and they are suitable for all types of materials.

Some common machines that are used for deburring purposes include: sanding wheels, mounted points made of abrasives or high speed steel, pneumatic guns, files, tumbling machines where small and soft stones are tumbled in a container along with the components. Other types of deburring devices include: vibratory tumblers, finishing mills, metallic and nylon wire brushes, barrel deburring and polishing machines, automatic deburring and polishing machines, centrifugal deburring and polishing machines and micro mechanical deburring and polishing, etc. While using deburring guns, due care must be taken by wearing protective glasses with side mesh screens. Components such as gears are deburred on special tooth rounding machines. In some cases, the gear is mounted on a rotary chuck with a pneumatic gun that deburrs the tooth edge.

Radially-Compliant (RC) deburring machinery uses a turbine motor which uses dry, filtered, air. Axially-Compliant (AC) deburring machinery operates with a vane-style motor that needs filtered, lubricated air to work properly. RC machinery can usually access more confined areas and than AC units. The makeup enables for a wider range of access points for robot programming. RC machinery and tools are the only devices that are built for removing parting lines and flash. AC deburring tools are quicker and generally preferred over RC units for edge deburring.
