Industrial brush applications such as deburring or surface finishing are more and more often carried out in a fixed setup situation. Composite brushes from PFERD have been specifically developed for industrial, automated use. They are suitable for a variety of applications and their variable clamping options mean that they can be used on many different drive systems. This offers the advantage that workpieces can be produced and finished on the same machine. As a result, there are no additional setup times, labour-intensive manual work is reduced and reproducible results are achieved with short cycle times.
PFERD, one of the world’s leading manufacturers of tools for surface finishing and metal cutting, offers a comprehensive and efficient line of composite brushes especially for these kinds of applications.
“The manufacturing method is what distinguishes composite brushes from ‘conventional’ brushes. This manufacturing method allows a higher filament density and an even distribution of the lament material. This results in a longer tool life, more aggressiveness and reproducible deburring results,” explains Thomas Rühle, product manager for industrial power brushes at PFERD.
Composite brushes consist of a plastic main body in which the brush filament is firmly fixed or embedded. The filament consists of flexible plastic filament containing abrasive grains. Composite brushes from PFERD are available with a large number of filament types and configurations. Among others, aluminium oxide, silicon carbide and ceramic oxide grain are used as an abrasive grain. When these grains are combined with different filament diameters and geometries, different brushing effects are achieved.
“Wheel brushes, disc brushes and end brushes with different dimensions are used as brush bodies. This way, we can work on almost any workpiece geometry,” says Rühle.
“Shank-mounted disc brushes DBUR with a bridle are a new addition to the line. Because of the 6mm shank, they can easily be mounted on hand-held drives or stationary machines,” adds Thomas Rühle.
“The bridle surrounding the filaments ensures that they are evenly compact under load and contributes to the special aggressiveness. Once the filament is worn down to the bridle, it can be removed so that the brush can continue to be used until the end of its service life. Our customers achieve very long tool lives and very high surface qualities with these brushes.”
“Shank-mounted end brushes PBUPR with a bridle are another new addition to the line. They also have a very aggressive brushing effect, and their service lives are just as long. PBUPR brushes have the stabilising bridle too. Thanks to their compact design, they are particularly suitable for working on hard-to-reach areas, such as drilled holes and cavities.”
