Did you know it is possible to round edges on parts as small as 30×30 mm?
Many edge rounding systems struggle with small parts. In some cases, processing is only possible under very limited conditions — in others, simply not feasible.
HOW IS IT POSSIBLE TO PROCESS PARTS AS SMALL AS 30×30 MM?
NS Máquinas crossbelt systems are designed to ensure maximum part stability during processing.
→ Three pressure rollers (before, between and after the crossbelts) maintain continuous pressure and support
→ Crossbelts run perpendicular to the feed direction, creating opposing forces that help stabilize the part
→ Special Design High-grip conveyor belt increases friction and keeps parts securely in place
→ Short distance between pressure points minimizes any free movement
This results in:
✔ Reliable for parts as small as 30×30mm
✔ Edge rounding on all internal and external edges
✔ Consistent and repeatable process
✔ Directional surface finish as a natural result of the process
✔ No need for vacuum tables or complex part holding systems
✔ Lower energy consumption and reduced system complexity
❌ VACUUM TABLE SYSTEMS
• Require additional systems (pumps, electronics, airflow control, increased dust extraction capacity)
• Higher energy consumption
• More maintenance
• Flat conveyor with holes offers intermittent grip
• Small parts must be carefully positioned over suction areas
• Loss of efficiency if cleaning is not maintained
• Increased machine complexity and cost
❌ TOP-BRUSH/ROTARY BRUSH
• Rely on rotating brushes applying force directly over the part
• Provide less support and stabilization than crossbelt systems
• Parts remain exposed to rotational forces for longer distances
• Higher risk of part movement, especially on small dimensions
• Limited control compared to systems with short, defined pressure points
In multi-brush rotary systems, these limitations become even more critical:
• Larger brush diameters increase instability
• Multiple brushes apply force simultaneously
• Small parts are even more difficult to keep in position
• Reliable processing often depends on vacuum systems or fixtures
✅ CROSSBELT MAKES THE DIFFERENCE
Crossbelt technology is designed to ensure maximum part stability throughout the process.
By combining controlled pressure, opposing forces and a high-grip conveyor, it allows reliable edge rounding — even on very small parts — without the need for vacuum tables or complex holding systems.
This results in a more stable, efficient and consistent process, independent of part size.
