HBR Hammer, Belt & Rotary Brush Machine
For thermal-cut parts that carry slag AND need finished edges. The hammer head fractures slag and heavy dross, the belt deburrs and cleans the surface, and the brush group rounds every edge — three operations replaced by one pass.
- Hammer head + abrasive belt + rotary brush group
- 800–1,600 mm working widths
- Slag, burrs and edge rounding in one pass
- For plasma- and flame-cut parts
HBR Quick Facts
Configuration: Hammer head + abrasive belt + rotary brush group
Working Widths: 800 / 1,000 / 1,300 / 1,600 mm
Best For: Plasma- and flame-cut parts with slag or heavy dross that also need rounded edges
Hold-Down: Magnetic (carbon steel) / vacuum (stainless steel, aluminium)
One-Pass Result: Slag and burrs removed, edges rounded — thermal-cut to finished in one pass
Slag, Burrs and Sharp Edges — One Machine
Plasma and flame cutting leave the hardest combination in metal finishing: slag and dross fused to the underside of the part, burrs along the cut, and edges too sharp to handle or coat. The usual answers each solve only part of it — deslagging machines stop at clean, deburring machines cannot take fused slag at all, and the edges still get finished by hand. The HBR sequences all three jobs in one pass: the hammer head fractures the slag, the abrasive belt deburrs and cleans, and the rotary brush group rounds contours and hole edges.
If you only need slag off and the edges do not matter, the dedicated slag removal configurations are the simpler machines. For laser-cut parts without slag, the BR starts with the belt and skips the hammer. For burr-free parts that only need rounding, see the R and RR.
Inside the HBR: Three Stations, Three Jobs
Station 1 · Hammer Head
Fractures slag and heavy dross first, breaking the fused layer off the underside and edges before it can load the belt.
Station 2 · Abrasive Belt
Deburrs and cleans the surface, removing the burrs and residue the hammer leaves behind.
Station 3 · Rotary Brush Group
Rounds contours and hole edges uniformly — the finished edge that slag-only machines cannot give.
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.
Three Operations, One Pass
Replaces Three Separate Operations
Deslagging, deburring and edge rounding usually live on different machines — or on one machine plus a grinding bench. The HBR runs them in sequence, so parts move through once instead of being handled three times.
Slag Gone, Edges Finished
A slag-only machine leaves sharp edges behind; a deburring machine cannot touch fused slag. The HBR is built for parts that need both ends of the job done properly.
Built for Thermal-Cut Work
Thick plasma- and flame-cut plate is the HBR’s home ground. The hammer station absorbs the slag load first, which is what lets the belt and brushes finish the part instead of fighting it.
Before and After One HBR Pass
A slag-covered plasma-cut plate before, and the same plate after one HBR pass — slag and burrs removed, surface cleaned, edges rounded.
BEFORE
AFTER — ONE PASS
HBR Is the Right Choice When…
- Plasma- or flame-cut parts carry slag AND need rounded, coating-ready edges
- Deslagging, deburring and edge finishing are separate steps in your shop today
- Thick thermal-cut plate is your main work
- Hand grinding after deslagging is your bottleneck
Choose Another Configuration When…
- You only need slag removed and edges do not matter: see the BB, HB and HBB
- Laser-cut parts carry no slag: the BR starts with the belt and skips the hammer
- Burrs are heavy but there is no slag: see the BBR in the Deburring & Edge Rounding configurations
- Parts are burr-free and only need edge rounding: choose the R or RR
Compare the Deburring & Edge Rounding Configurations
| 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 |

HBR Hammer, Belt & Rotary Brush Machine — Frequently Asked Questions
What does the Lasvio HBR do?
The HBR removes slag, deburrs and edge-rounds thermal-cut parts in one pass. The hammer head fractures slag and heavy dross, the abrasive belt deburrs and cleans the surface, and the rotary brush group rounds contours and hole edges — plasma- and flame-cut parts come off the conveyor finished.
How is the HBR different from the BR?
The BR starts with an abrasive belt and suits laser-cut parts that carry no slag. Fused slag would load and damage a belt, so the HBR puts a hammer head first to fracture it. If your parts carry no slag, the BR is the simpler machine.
How is the HBR different from the HB?
The HB removes slag with a hammer and a belt, but it does not round edges. The HBR adds the rotary brush group, so edges come out rounded in the same pass. If you only need slag off, the HB and HBB are the dedicated machines.
Can the HBR handle thick plasma-cut plate?
Yes — thick thermal-cut plate is its main work. It processes parts from 0.5 to 80 mm thick, and the hammer station takes the slag load first, so the belt and brush stations can finish the part at production feed speeds.
How do I confirm whether HBR fits my parts?
Send the material, thickness, cutting method and the finish you need — or arrange a sample test on your actual parts. If your parts carry no slag, we will point you to the BR instead; if you only need slag removed, we will suggest the HB or HBB.
Send Your Parts for an HBR Test
Parts moving between a deslagging step, a deburring step and a grinding bench? Send us the part details — or your actual parts — and we will run them through the HBR and show you the finished result. If your parts carry no slag, we will point you to the BR instead.
