Product Name:
Resin Injection Disc Brush - Equal Divide Type (4-Segment Aluminum Oxide Abrasive Disc Brush)
Product Size:
Customizable according to customer requirements – brush body shape, filament profile, and base plate are fully customizable
Material Composition:
Filament Material: Aluminum oxide (AO) abrasive-filled nylon filaments
Handle/Backing Material: PP/PVC resin injection molded one-piece integrated base – filament loss prevention with customized screw holes for multiple equipment compatibility
Product Features:
Equal divide 4-segment design – segmented brush face provides balanced surface contact and consistent performance across the entire disc
Aluminum oxide abrasive filament – hardness slightly lower than silicon carbide, delivering smoother and more stable cutting action
Ideal for aluminum and soft alloys – commonly used for deburring aluminum alloy and other soft alloy workpieces, as well as surface polishing and metal surface finishing
Resin injection molded base – PP/PVC one-piece integrated construction prevents filament loss and ensures durability
Customizable mounting – customized screw hole locations available for compatibility with multiple equipment types and automation systems
Wide application range – as widely applied as silicon carbide brushes in industrial surface finishing
Excellent surface finish – achieves scratch-free surface treatment on soft metals and alloys
No bristle loss & falling off – secure filament anchoring for precision applications
Long service life – consistent abrasive performance throughout brush life
Applicable Scenarios:
Alloy surface treatment – removing burrs, scales, and imperfections from alloy workpieces

Surface deburring – removing sharp edges and burrs from machined alloy components
Metal surface finishing – general precision finishing across multiple alloy types
Aluminum alloy deburring – deburring automotive aluminum castings and components
Soft alloy finishing – polishing and deburring brass, copper, and other non-ferrous alloys
Flat surface conditioning – large-area surface preparation and refinement
Automated finishing lines – compatible with CNC machines and robotic cells
What Makes Equal Divide Aluminum Oxide Disc Brushes Different?
Our Resin Injection Disc Brush - Equal Divide Type (4-Segment Design) features a segmented brush face that provides balanced surface contact and consistent performance across the entire disc. The aluminum oxide (AO) abrasive filaments deliver a smoother cutting action than silicon carbide, making this brush particularly suitable for aluminum alloy and other soft alloy applications where over-cutting or surface scratching must be avoided.
The PP/PVC resin injection molded one-piece integrated base ensures secure filament anchoring with no bristle loss. Customizable screw hole locations allow this brush to be mounted on a wide variety of equipment, from manual polishing machines to fully automated CNC finishing cells.
Equal Divide Disc Brush vs. Full Face Disc Brush
| Feature | Equal Divide (This Product) | Full Face Disc Brush |
|---|---|---|
| Face configuration | Segmented (4 equal sections) | Continuous full face |
| Coolant/debris flow | Excellent (gaps between segments) | Limited |
| Pressure distribution | Even across segments | Even across entire face |
| Best for | General surface finishing, softer alloys | Aggressive material removal, harder materials |
| Heat dissipation | Better (open design) | Moderate |
| Conformity to contours | Good | Excellent |
Comparison with Silicon Carbide (SiC) Abrasive Disc Brush
| Feature | AO Abrasive (This Product) | SiC Abrasive |
|---|---|---|
| Hardness | Moderate | High |
| Cutting action | Smooth and stable | Aggressive |
| Best for | Aluminum, brass, soft alloys | Steel, iron, hard metals |
| Surface finish | Excellent (scratch-free) | Good |
| Risk of over-cutting on soft metals | Low | Moderate |
| Application range | As widely used as SiC in automotive and general finishing | As widely used as AO in heavy-duty applications |
Key Applications in Detail
Alloy Surface Treatment
Removing burrs, scales, and surface imperfections from alloy workpieces requires controlled cutting action. The AO abrasive provides smooth material removal without damaging the base material, making it ideal for finishing cast and machined alloy components.
Surface Polishing
Achieving smooth, refined finish on flat and contoured metal surfaces demands consistent contact across the entire workpiece. The equal divide design allows for even pressure distribution while the segment gaps promote debris clearance.
Surface Deburring
Removing sharp edges and burrs from machined alloy components – from automotive parts to general industrial components – requires a brush that can access edges without over-cutting. The flexible abrasive filaments conform to edge geometries for clean burr removal.
Aluminum Alloy Deburring in Automotive Applications
The automotive industry widely uses aluminum alloy for transmission housings, engine components, and structural parts. The smoother cutting action of AO abrasive makes this brush particularly suitable for these applications where part integrity and surface quality are critical.
For Aggressive Cutting Applications
If your application requires aggressive cutting action on steel, iron, or hardened materials, consider our Resin Injection Disc Brush - Full Face Type or Resin Injection Ceramic Fiber Disc Brush.
