Burrs can occur not only on edges but also on surfaces. This can be the case, for example, with stamped parts or with surfaces that have been machined. The "leftovers" in the form of loose burrs, particles, or flakes created by the manufacturing process can lead to unwanted scratches on surfaces. They can interfere with the assembly of a component or even contaminate other components if they fall off.
Especially in industries where the cleanliness of components is essential (pharmaceuticals, food, semiconductors, etc.), deburring of surfaces must take place, and, above all, it must be process-safe. Thorough deburring is ultimately also the basic prerequisite when surfaces are subsequently coated or painted. Poor deburring can lead to flaking of the coating.
On surfaces or flat components, disc brushes are primarily used for deburring, sometimes also wheel brushes. Disc brushes are very flexible tools. Due to their nature, they are very well suited for working on flat surfaces.
Wheel brushes are used when a flat component does not consist of a continuous surface but is perforated, which means there are also edges within the surface due to the manufacturing process (e.g. for vents in enclosures). The wheel brush is more suitable to deburr the edges within the surface.
Surfaces or flat components made of steel, sintered metal, or aluminum are mainly deburred with abrasive trimming material such as ceramic, silicon carbide, or aluminum oxide. For cast iron and non-ferrous metals, a crimped steel wire or stainless steel wire is used. Class 5 burrs, where the material is displaced by a cutting tool, need more aggressive machining. Here, crimped wire is used almost exclusively.
