Manual deburring often creates inconsistent edge quality, high labour dependency and variable finishing results. The Valgro RBM Series provides an automated and repeatable solution for manufacturers who require burr-free parts, rounded edges and a uniform surface appearance.
The abrasive belt removes vertical burrs, slag traces and surface imperfections. The rotary brush system works around internal and external contours to create controlled edge rounding, while the finishing roller produces a uniform surface pattern.
A vacuum conveyor securely holds lightweight, thin and small components during processing. This helps achieve stable movement, consistent finishing and reduced rework.
The RBM Series is especially suitable for components requiring improved handling safety, coating coverage, assembly fitment and professional appearance.
Customer benefits:
- Complete deburring, edge rounding and surface finishing in one machine
- Edge-radius capability up to R2 mm
- Consistent treatment of internal and external edges
- Reduced manual grinding and operator dependency
- Improved safety when handling finished components
- Better edge coverage during painting and powder coating
- Repeatable quality across production batches
- Lower rework and improved production efficiency
Achieve Safer Edges and Consistent R2 Edge Rounding
Send us your component drawings and representative samples. Valgro’s application engineering team will evaluate the burr condition, material, required radius and surface-finish expectations to recommend the appropriate RBM configuration.
Features
All-in-One Metal Finishing
Combines abrasive belt grinding, rotary brush edge rounding and surface finishing in one automated process.
Powerful Burr Removal
The abrasive belt head removes vertical burrs, laser-cutting residue, slag traces, sharp projections and surface imperfections.
Controlled Edge Rounding up to R2 mm
The rotary brush system treats internal holes, external profiles and complex contours to create smooth, consistent edges.
Uniform Surface Finish
The finishing unit creates an even satin, matte or directional scratch pattern depending on the selected abrasive media.
Secure Small-Part Processing
The vacuum conveyor holds thin, lightweight and smaller components securely throughout the finishing process.
Automatic Media-Wear Compensation
The control system helps compensate for abrasive wear to maintain stable processing pressure and consistent results.
Quick Abrasive Changeover
A user-friendly abrasive replacement system reduces setup and maintenance time between production batches.
Touchscreen HMI Control
The operator can conveniently manage machine settings and repeat approved process parameters.
Ready for Downstream Operations
Finished components are better prepared for powder coating, painting, plating, welding, bonding and final assembly.
