Explanation of Orbital Riveting Working Principle

This unique motion of the ST-MSF-500 Servo Riveting Machine transforms axial force into a uniform radial material flow. It results in reliable, crack-free joints with a smooth finish, using only 10% to 20% of the force required by traditional press riveting.
Orbital riveting is an advanced cold-forming process maintaining a precise tilt angle (typically 3 to 8 degrees) between the spindle and die. During operation, the spindle drives the die in a continuous 360 degree eccentric orbital movement while feeding along the Z-axis.

Advanced Features of ST-MSF-500 Servo Riveter

Our servo orbital riveting enables diverse shapes — including Flat, Countersunk, Ball Head, Flared, and Custom forms — to meet varied functional and space requirements. We provide standard shape options (S1–S9) and support tailored designs for precise, reliable, and space-efficient joints.
