Car Brakes
WHAT
The anti-vibratory liner secured on the brake pads prevents vibration during braking. This plate of one or two millimeters in thickness is an alloy with a rubber coating.
WHY
The liner has to be riveted properly to avoid the risk of braking and a broken-off piece getting jammed in the brake. The shim must be assembled with a margin so that it cannot tear off and get stuck in the brake calipers making it impossible to break. The formed rivet head must not protrude from the part, otherwise the brakes will also be blocked. But the lower part of the pads has very large tolerances due to its manufacturing process and material.
HOW
We used an RNE 231 with HPP-25 Process Control, equipped with an NHE rivet base detection. We just touched the liner and formed to a specific head height (H). Consequently, we were able to guarantee a repeatable head height with respect to the reference surface (the liner). Monitoring the process ensures for the formed head to always be below the friction surface of the wear clips. Traceability is ensured by recording process data of each cycle.
