BBR Double Belt & Rotary Brush Deburring Machine
When one belt is not enough. Two abrasive belt stations share the deburring work — the first knocks down heavy burrs, the second levels and cleans — and the rotary brush group rounds every edge in the same pass. Built for medium and thick plate with burrs a single-belt machine leaves behind.
- Two abrasive belts + rotary brush group
- 800–1,600 mm working widths
- Heavy burrs removed, edges rounded — one pass
- Stronger deburring than the BR
BBR Quick Facts
Configuration: Two abrasive belts + rotary brush group
Working Widths: 800 / 1,000 / 1,300 / 1,600 mm
Best For: Heavy burrs on medium and thick plate, with full edge rounding
Hold-Down: Magnetic (carbon steel) / vacuum (stainless steel, aluminium)
One-Pass Result: Burrs gone, edges rounded — heavier stock finished in one pass
Heavy Burrs Need More Than One Belt
Thick laser- and plasma-cut plate throws up tall, hard burrs. A single belt station has to choose: run slowly, or leave burr standing. The BBR splits the work between two belts — the first knocks the heavy burr down, the second levels and cleans the surface — and the rotary brush group rounds contours and hole edges in the same pass. Heavier stock gets finished at production feed speeds, not nursed through.
For standard laser-cut parts, one belt is enough — see the BR. For parts that carry slag as well as burrs, the HBR adds a hammer station in front. If the surface finish matters more than the burr load, see the BRB in the Deburring & Edge Rounding configurations.
Inside the BBR: Two Belts, Then the Brushes
Station 1 · First Abrasive Belt
Takes the heavy burr load — knocks down the tall, hard burrs on medium and thick plate.
Station 2 · Second Abrasive Belt
Levels the surface and cleans what the first belt leaves, so no single belt has to do all the work.
Station 3 · Rotary Brush Group
Rounds contours and hole edges uniformly, finishing the part in the same pass.
Hold-down for every material: a magnetic table holds carbon steel; a vacuum table holds stainless steel and aluminium flat — small parts run safely at full feed speed.
Why Two Belts Change the Job
Built for Heavy Burrs
Tall, hard burrs on medium and thick plate overload a single belt. The BBR’s first station exists for exactly that load.
Consistent in Batch Production
Two stations sharing the work hold their results steady across long batch runs — the finish on the last part matches the first.
Still One Pass
Heavier deburring without giving up the brush finish: parts leave deburred AND rounded, not deburred and queued for a second machine.
Before and After One BBR Pass
The same part before and after one BBR pass — burrs gone, edges rounded.
BEFORE
AFTER — ONE PASS
BBR Is the Right Choice When…
- Burrs are heavy and tall on medium and thick plate
- A single belt leaves burr standing, or forces you to slow the feed down
- Batch runs need the same finish on the last part as the first
- Parts are laser- or plasma-cut with no fused slag
Choose Another Configuration When…
- Standard laser-cut parts with a normal burr load: the BR covers them with one belt
- Parts carry slag as well as burrs: the HBR adds a hammer station in front
- Surface finish matters more than burr load: see the BRB in the Deburring & Edge Rounding configurations
- Parts are burr-free and only need edge rounding: choose the R or RR

| Configuration | BR | HBR | BBR | BRB |
|---|---|---|---|---|
| Configuration | Belt + rotary brush | Hammer + belt + rotary brush | Two belts + rotary brush | Belt + rotary brush + belt |
| Main Result | Deburring and edge rounding for laser-cut parts | Slag removal with deburring and edge rounding | Heavier burrs with full edge rounding | Edge rounding with a cleaner, mark-free surface |
| Choose It When | Most laser-cut parts — the all-round configuration | Parts carry slag as well as burrs | The burr load is heavier than one belt can handle | Surface quality matters most, on cosmetic parts |

BBR Double Belt & Rotary Brush Deburring Machine — Frequently Asked Questions
What does the Lasvio BBR do?
The BBR deburrs and edge-rounds heavy-burred parts in one pass. Two abrasive belt stations remove the burr load — the first knocks down tall, hard burrs, the second levels and cleans — and the rotary brush group rounds contours and hole edges.
How is the BBR different from the BR?
The BR runs one belt station, which covers most laser-cut parts. When the burr load is heavy, one belt has to slow down or leave burr standing. The BBR’s two belts share the work, so medium and thick plate finishes at full feed with the same rounded edges. For standard parts, the BR is the simpler machine.
Can the BBR remove slag?
No — the BBR has no hammer station, and fused slag belongs on a machine that does. For slag-carrying parts, look at the HBR or the dedicated HB and HBB slag removal machines. The BBR is built for burrs, not slag.
Which parts suit the BBR best?
Medium and thick laser- and plasma-cut plate with heavy burrs, and batch production where the finish has to stay consistent across the whole run.
How do I confirm whether BBR fits my parts?
Send the material, thickness and burr condition — or arrange a sample test on your actual parts. If one belt can handle your burrs, we will point you to the BR instead.
Send Your Parts for a BBR Test
Burrs slowing your line down — or surviving the machine you have? Send us the part details — or your actual parts — and we will run them through the BBR and show you the finished result. If one belt can handle your burrs, we will point you to the BR instead.
