Brush
Deburring (CBR)
Rotating wire or abrasive-filament brushes remove burrs from accessible edges, round sharp corners and clean the surface. Simple, fast and easily integrated into CNC machining centres.
How Brush
Deburring Works
A rotating brush (wire, nylon-abrasive or CBN) contacts the edge. The brush filaments deflect around the feature and remove the burr by abrasive or wire action.
Tool selection
Brush type is selected based on burr size and material: wire brush for heavy burrs, abrasive filament for fine edges, disc brush for flat surfaces.
Brush engagement
The brush engages the edge at controlled speed and feed rate. Filaments conform to the edge geometry.
Edge rounding
Repeated passes round the edge to the required radius. The process is programmable in CNC machining centres.
Where Brush Deburring
Is Used
Brush deburring is the most widely used method for accessible external edges in machining and production environments.
CNC machined parts
Inline deburring of milled and turned parts directly in the machining centre — no additional operation or handling.
Flat surfaces & bores
Disc and cup brushes remove face burrs and deburr bore entries in a single pass.
Sheet metal & stampings
Edge burrs from blanking and punching are removed on inline brush machines.
Gears & shafts
Tooth root burrs and shaft shoulder burrs are removed with specialised profiled brushes.
Why Brush Deburring
- Integrates directly into CNC machining centres
- No additional handling or separate operation
- Flexible — same brush can follow complex edge contours
- Low investment and tooling cost
- Suitable for aluminium, steel, cast iron and non-ferrous metals
- Edge radius is controllable
- High processing speed
- Easy to automate with robots
