Rotary and radial riveting machines are both used for mechanical riveting applications, but their forming motions are different.

Understanding this difference can help manufacturers select the appropriate riveting technology for a particular workpiece and production process.

Rotary Riveting

A rotary riveting machine forms the rivet through a rotary motion.

The riveting tool rotates while applying pressure to the rivet, gradually forming the rivet head.

This method can provide a controlled forming process and is commonly used for industrial components requiring consistent riveting.

Radial Riveting

Radial riveting uses a different forming movement.

The riveting tool follows a radial motion while forming the rivet. The resulting process can provide controlled deformation of the rivet while limiting unnecessary impact on the surrounding workpiece.

Radial riveting machines can be used for a range of metal component joining applications.

What Is the Difference?

The main difference is the movement of the riveting tool during the forming process.

Rotary riveting:
The tool performs a rotary forming movement.

Radial riveting:
The tool follows a radial forming movement.

The appropriate method depends on factors such as rivet material, rivet diameter, workpiece material, joint design, required forming result and production requirements.

Selecting a Riveting Machine

Before choosing a riveting machine, manufacturers should consider:

• Rivet type

• Rivet diameter

• Workpiece material

• Workpiece dimensions

• Required riveting force

• Riveting stroke

• Tooling requirements

• Production volume

• Required automation level

Conclusion

Rotary and radial riveting are both established industrial joining methods, but they should not be treated as interchangeable technologies.

The best choice depends on the actual rivet, workpiece and production process.
