Technical Brushes Simple and Economical Deburring

Editor: MA Alexander Stark

Brushes are used to remove burrs, round edges and remove tinsel without chemicals or heat. In addition, brushes can be easily integrated into existing manufacturing processes.

In contrast to (electro)chemical and thermal deburring technologies, the particular strengths of brush deburring are in the simple handling and flexibility of the brushing tool. A large selection of brush types is available in different geometries and with fill materials that can be easily adapted to a specific application.

Depending on whether an abrasive or a knock-off effect is to be achieved, the brush manufacturer Kullen-Koti recommends high-quality brushing tools with abrasive filaments or steel wires. While the abrasive filaments can be matched to the application through the type of grain (SiC, AlO, diamond, ceramic, etc.) and different grain sizes, wire-tipped brush tools differ in the hardness and diameters of the wires (0.06 mm - 1.2 mm) as well as their geometry (corrugated, stranded, knotted). This provides the user with a perfect tool for mechanical deburring of semi-finished products and components made of soft or hardened steel, stainless steel, hard metal, sintered metal as well as aluminum, copper and many other materials.

In principle, brush deburring is suitable both for workpiece weights of a few grams and for components weighing several tons and can be used for soft materials as well as for hard materials. Another advantage: The process is independent of the quantity to be treated; it is just as efficient for batch sizes of 1 as for large series production. Thanks to the simple tool change and their partially very long service life, especially in fully automated applications, technical brushes can be an extremely economical solution. Long downtimes and set-up times as are avoided, and special preparation of the brushes is not required. In addition, most deburring brushes can be used both in wet and dry operation.
