Power Brush

Power brushes are tool widely used for the heavy duty applications such as deburring, weld cleaning, rust and paint removal, wire stripping etc. These brushes are available in a variety of styles including wheel, cup, mandrel mounted etc. Electric toothbrush is also an example of these power brushes.

Detailed Description for Power Brush

Industrial professionals make use of such power brushes for edge blending, polishing or removing contamination from the surface of object. These are functioned by horsepower which typically depends on the amount of pressure required for the application. Materials used for manufacturing these tools include variations of ferrous and non-ferrous wires, carbon steel, natural and synthetic fibres.

Applications of power brushes

1.       Deburring- Power brushes are extensively used for removing edges and ridges created as a result of machining operation. Power brushes can completely remove these burrs without creating any secondary such edge or surface or leaving two sharp edges.


2.       Surface Finishing- Power brushes are ideal tools for removing burrs and improving surface finishes to gain the desired appearance of the object. Brushes do not remove the base materials but rather they remove only those metal particles left on surfaces which have been grounded or abrasive polished.


3.       Edge Blending: These brushes could also be brought into use for rounding of the edges at the junction of two surfaces of an object. Power brushes perform this application without removing material on the corresponding surface or edge. It reduces the stress concentration and part fatigue and improves the surface finish.


4.       Roughening: Surface can be made rough also using power brushes for creating better bonds on surface such as rubber, leather plastics and non-ferrous materials. Surfaces are roughened prior to painting or bonding to achieve the better adhesion.


5.       Cleaning: Power brushes are suited for removal of surface film, dirt, dust, weld slag, corrosion etc.


Advantages of power brushes

·         Rugged construction: Tough enough to stand under heavy and prolonged use.


·         Easy on equipment: Being non-abrasive, they do not produce equipment-destroying abrasive dust.


·         True selective cutting: Removes surface contamination without cutting away any base material.


·         Stress relieving and surface conditioning: Brushing action produces the same effect as shot peeing (a method used in aircraft and race cars to increase the life cycle of highly stressed parts) without adding any extra operations.


            Power brush types:

1.       Wheel brushes: Circular in shape and generally no wider than 2 inches in diameter. Standard wheel brushes range from 5/8” to 15” in diameter. There are two basic forms of wires used in wheel brushes- Crimped Wire for flexibility and Straight Wire for knot type.


2.       Wide face brushes: Face is greater than the diameter. Specially designed for specific customer application.


3.       Cup brushes: These brushes are generally lined with wire or abrasive filled nylon and used on portable power tools.


4.       Tube brushes: Twisted-in-wire types to be used on portable tools and drill presses to clean and finish holes and internal threads.


Stem mounted brushes: Generally used in portable air and electric tools for light to heavy duty work where space is limited.
