Without corners and edges

Brush deburring is a purely mechanical surface technology process. It is suitable for deburring and rounding the edges of workpieces made of steel and iron, non-ferrous, light and sintered metals as well as engineering plastics. It can also be used very efficiently to remove flitter burrs and clean cast parts. In industrial practice, brush deburring can be used with hand-held tools and conventional automatic processing machines as well as in fully automated production cells with CNC systems and industrial robots. It relieves the user of the need to invest in expensive, complex plant technology and is considered to be particularly sustainable, as it does not require the addition of chemicals or the supply of thermal energy. The tool brushes required for the process engineering implementation can usually be clamped into existing machines, which considerably simplifies the integration of brush deburring into existing production environments. As it is also suitable for semi-finished products and batch size 1 components as well as for mass processing, brush deburring is just as attractive for prototype builders, small series and contract manufacturers as it is for large series manufacturers and OEMs.

Plenty of scope for the right choice

According to the theory, brush deburring is one of those mechanical deburring processes in which rotating tools with an "indeterminate cutting edge" exert a targeted effect on the surface of the workpiece. A decisive factor for the performance of brush deburring is therefore the nature of this "cutting edge" - in this case the brush fill. In other words, when selecting the most suitable tool brush for deburring, rounding or cleaning, the material, geometry and design of the filament must always be optimally matched to the application. Brush manufacturers such as Kullen-Koti therefore offer their customers a selection of filament types with abrasive filaments and special wires. They give a deburring brush an abrasive or knock-off effect. While the needs-optimized adjustment of the abrasive brushes is made via the filament material (SiC, AIO, diamond, ceramic, etc.) and the size of the grit, the wire filaments are adjusted via the hardness of the wire material, the diameter (0.06 - 1.2 mm) and the design (crimped, twisted, knotted, etc.).

Use existing peripherals

In principle, the choice of trim offers the user a great deal of scope to directly influence the desired deburring result. Typical objectives include high removal rates in short cycles, reliable internal deburring of deep holes, continuous smoothing of very long profile edges or edge rounding with extreme accuracy in the µm range. The advantage in this context is that, as brush deburring does not require extensive preparatory work or complex process technology, the user is usually able to carry out test runs and test series with different deburring brushes quickly and easily on their own. If important detailed questions arise - such as roughness, penetration depth or the thermal and chemical resistance of special trimmings - they can also consult the experts at Kullen-Koti at any time.

The situation is similar when determining two other parameters that can be highly relevant for selecting the most suitable deburring brush: The speed at which the brush rotates and the way in which it is brought to the workpiece. In other words, at what speed should the clamped tool brush ideally rotate and should the feed or infeed take place on the machine or workpiece side? When clarifying these questions, the customer can make use of the know-how and experience of the consultants; for practical implementation, however, many users can fall back on existing production facilities and handling systems. Brush deburring can therefore often be integrated very easily into the work processes even in small companies with conventional automatic lathes and power tools or in craft-oriented manufactories.

For all facets of deburring technology

Brush deburring provides metal and plastic processing companies with a deburring process that can be used for workpiece weights of just a few grams as well as for components weighing several tons. It is also suitable for soft materials as well as harder materials. However, it is not recommended for very hard materials and the height of the burrs should not exceed 0.2 mm. As deburring technology is also rich in varieties and facets, Kullen-Koti offers various types of brush systems for this purpose: Disk brushes for robot-assisted surface finishing, round and single disk brushes for the highly efficient cleaning of weld seams, brush and cup brushes for deburring separation points or internal and alpha-hon brushes for processing bores and cross intersections. Most deburring brushes can be used both wet and dry. No special pre-treatment of the brushes is required.
