SHEET METAL EDGE ROUNDING MACHINE
Sheet Metal Edge Rounding Machines: R and RR
Create consistent radiused edges on laser-cut, punched, and sheared sheet metal parts with one or two universal rotary brush units.
Common Processing Challenges
Laser cutting, punching, and shearing often leave edges that are too sharp for safe handling or stable powder coating. Manual rounding can work for small batches, but consistency becomes difficult as production volume grows.
Sharp edges after cutting
Unsafe manual handling
Inconsistent edge radius
Poor coating adhesion
Manual grinding bottlenecks
Quality variation between operators
What It’s Built For
R and RR configurations use universal rotary brushes to contact external edges, internal contours, and openings from multiple directions.

Edge rounding configurations
Choose R for efficient edge rounding or RR for greater rounding intensity
Both configurations use universal rotary brushes for multi-directional contact with straight edges, contours and internal openings. Select the number of brush units from the required radius, part geometry and production volume.
R
One universal rotary brush unit
A compact configuration for routine edge radiusing and safer handling.
- Lower consumable count
- Light-to-moderate radius targets
- 800mm, 1000mm, 1300mm & 1600mm widths
RR
Two universal rotary brush units
Additional brush contact for more intensive, consistent edge rounding on complex parts.
- Higher edge-rounding capacity
- More contact across mixed contours
- 800mm, 1000mm, 1300mm & 1600mm widths

- Better welding preparation quality
- Cleaner and safer finished parts
FAQ
What is the difference between R and RR?
R uses one universal rotary brush unit for standard edge rounding. RR adds a second brush unit for greater rounding intensity or higher production requirements.
Can edge rounding improve powder coating quality?
Yes. A consistent radius helps coating wrap around edges more evenly and reduces weak points at sharp corners.
Can the machine round internal holes and contours?
Universal rotary brushes contact edges from multiple directions, making them suitable for external edges, contours and many internal openings.
How do I choose the right edge rounding configuration?
Send material, thickness, part drawings or photos and target edge radius. Lasvio can recommend R or RR based on the required result.
