Spin Riveting Machine

Sai Machine Tools offers Ultra brand Spin Riveting Machine. With orbital riveting and orbital forming, this is an optimal machine for many riveting applications. An orbital riveter is a unique riveter. In spin riveting the tool is mounted on a rotating spindle with the axis of the tool fixed at an angle 3-6 degrees off the axis of the spindle. As the spindle rotates the tool orbits the spindle axis and transcribes the pattern of an inverted cone. The tool does not rotate on its own axis. The tool axis intersects the spindle axis at the working end of the tool and the orbital tool presses on the rivet shank along a radial line that begins from the shank centre. Orbital riveting is a method of joining multiple parts together by cold forming the end of the rivet. The resulting joint may or may not allow rotation of the mated parts depending on the product design. Typical solid rivet size range from 0.5 mm to 50 mm diameter. Orbital forming is a method of deforming material to desired shape with an orbital riveter. This process can be used to flare, swage and crown material from 0.5 mm to 150 mm diameter.
