Technical insights, product guides and practical information for industrial handling and riveting equipment.
Rotary and radial riveting are both established mechanical joining methods, but the riveting tools use different forming movements.
Understanding the difference can help manufacturers determine which process is more suitable for a particular application.
In rotary riveting, the riveting tool uses a rotary forming movement while applying pressure to the rivet.
The rivet is gradually formed into the required shape.
This process can be suitable for repeatable riveting applications involving compatible rivet and workpiece materials.
Radial riveting uses a radial movement of the riveting tool.
The tool gradually forms the rivet through controlled movement and pressure.
This can be useful when controlled rivet deformation and consistent joint formation are required.
The basic difference is the movement used to form the rivet.
| Factor | Rotary Riveting | Radial Riveting |
|---|---|---|
| Tool movement | Rotary forming motion | Radial forming motion |
| Rivet forming | Controlled forming | Controlled forming |
| Typical use | Industrial component joining | Industrial component joining |
| Tooling | Application-specific | Application-specific |
| Selection | Based on joint requirements | Based on joint requirements |
Neither process should automatically be considered superior.
The following factors should be evaluated:
Rivet material
Rivet diameter
Workpiece material
Joint design
Required riveting force
Tooling
Workpiece geometry
Production volume
The desired appearance and final shape of the rivet can also influence the selection.
Press riveting is another approach that uses controlled pressing force.
It may be appropriate for applications where the required joining process is better suited to direct pressing rather than rotary or radial forming.
Rotary, radial and press riveting are different approaches to mechanical joining.
The best process depends on the actual rivet, workpiece and production requirements. Machine selection should therefore start with the joint rather than the machine name.
