ATB®
ATB® is the abbreviation for Advanced Technology Brush System and forms our product range of brushes for automated deburring directly after the machining process.
ATB® - High-tech brushes for automated deburring.
ATB® brushes are precision tools that are largely responsible for the quality of the end products. They can be matched component-oriented to almost any material to be processed.
Our ATB® brushes are available with a wide range of abrasive bristles and wire trim in different grit sizes and filament/wire diameters.
ATB® brushes are designed for direct adaptation to tool holders, which means that they can be used in machining centers, CNC lathes & milling machines, robot cells, etc. The use of the brushes takes place downstream of the machining process.
The brushes are used downstream of the machining process and can be used with cooling lubricants, emulsions, or water without any problems.
water. This means that the machined workpieces can be deburred and finished directly, reliably, and reproducibly on the machine without reclamping.
Before/after comparison.
Before machining - clear burr formation on the edge. Milling grooves on the surface.
After machining - burrs were reliably removed and the edges rounded. The surface has an even, brushed look.
Advantages and
Application examples.
ATB® brushes have a 4 x higher fill density than the disc brushes produced in the conventional process (punched). As a result, the service life of the brushes is increased many times over, with higher throughput speeds and better and more efficient deburring results.
- Minimal process costs
- Firmly encapsulated abrasive bristles
- Extremely dense fill surface
- Enormously long tool life
- High dimensional stability and concentricity
- Use of cooling lubricant, emulsions, and water possible
- Plane fill surface
- Numerous, different fill materials e.g. abrasive bristles, wire materials, mixed fill material
- No reclamping of the workpiece after machining
Due to shorter machining times and very uniform edge rounding, our ATB® brushes are particularly suitable for deburring:
- Milled and turned parts
- Ground parts
- Sintered parts
- Stamped, nippled, and pressed parts
- Pneumatic and hydraulic parts
- Engine components, e.g. cylinder head, cylinder block, etc.
- Die-cast parts
- Valve plates
- Flat ground parts
- Toothed components
- Contact and sealing surfaces
- Finishing

Trim patterns & designs.
In order to achieve the best possible deburring and finishing results, different fill patterns and designs are required. Depending on the available product families of ATB® brushes, we offer the following fill types, among others:
ATB® disc brush
- full fill (max. fill density)
- partial fill (segmented)
- turboshape
- ring fill
- tapered/angled fill (under angle)
- spotted version
ATB® wheel brush
- full fill (max. fill density)
- partial fill (segmented)
ATB® End Brush
- full fill (max. fill density)
Determined by the material to be processed and the workpiece geometry, ATB® brushes can be equipped with various fill materials, from wire fill to abrasive bristles to mixed fill.
Technical feasibility & standard configurations.
In order to make the best possible use of the advantages of our ATB® product line, it is often necessary to exchange ideas with our product professionals. Often, application-specific brushing tools are worked out for the customer, which is developed taking into account the entire machining process.
We offer the following standard configurations (dimensions) for the three ATB® product families:

ATB Uni-Lok® Max Density Disc Brush
Designed to tackle the most demanding of applications, Osborn’s ATB Uni-Lok® Max Density Disc Brushes deliver maximum aggression and reliable, uniform performance. Brushes feature max density, premium quality Round Crimped abrasive nylon filament, making them capable of processing large burrs on stainless steel and hardened alloys without altering the part’s dimension. Expertly designed and tested for minimal cycle time and exceptional brush life.
ATB Uni-Lok® Turbo Disc Brush
Osborn’s ATB Uni-Lok® Turbo Disc Brush features Round Crimped abrasive filaments in a unique turbo design to effectively tackle moderate to severe burrs or tasks where conformability is required.
