Tube measuring with a system closely linked to bending machines
Brake and fuel lines for the E and S Class from Mercedes-Benz are manufactured in the tube production plant in Sindelfingen, Germany. The lines, made from aluminum or steel, have diameters ranging from roughly 4 mm to 15 mm. Supplied in fixed sizes, ready-cut tubes are first provided with fittings on an automatic tube end processing machine, swaged if necessary, and then formed on bending machines. Despite their different makes and years of manufacture, the tube bending machines all have one thing in common: their quality check takes place on the AICON tube measuring machine TubeInspect.
Each day about 1,400 vehicles are equipped with brake and fuel lines from the tube production plant, in more than 400 model variants. Prototypes for vehicle development are also built here. High precision naturally plays a crucial role. "We install 11 to 12 brake lines per vehicle, and so every millimeter is important", explains Siegfried Radegast, an engineer at the tube production plant. A method was sought what would make quality checks fast and uncomplicated, while enabling any detected errors to be corrected as quickly as possible on the tube-bending machines.
