BalTec Radial riveting rosette explained

Radial riveting technology

Basically, the application determines the procedure.

In most cases, however, where high-quality joints are demanded or like critical applications, the radial riveting technology is the appropriate procedure as it is a delicate process, which requires little force to displace the necessary material. As a result, high quality is obtained. 

Excellent surface structure of the closing head
With the radial riveting process, the tool itself does not rotate. The friction between tool and workpiece is thus at a minimum. The result is an excellent surface structure.
Low workpiece loading
Forming even of brittle parts like Bakelite or ceramic parts is possible. Lateral forces are negligible. Supporting the workpiece is simple, and clamping is usually unnecessary.
Tangential riveting
It is a process between radial and orbital riveting. The pattern is like the orbital process but with some benefits of the radial process. The path of the riveting peen does not lead through the center. This riveting is used in special cases.

Caption: Each rosette pattern R runs through the centre Z. The longitudinal axis of the riveting die still intersects the rivet at point N. The rivet is deformed in three directions. Radially outwards, radially inwards, and overlying also tangentially (circular).

RADIAL RIVETING

All BalTec radial riveting machines are fitted as standard with tool holder and pressure cup. The tool length (Ls) and the radius of the holder (Rp) result from your desired free height (H).
