Measuring Millions (of Armature Pins)

At the Robert Bosch plant in Hildesheim, Germany, 8.5 million starter armatures are produced annually.

At the Robert Bosch plant in Hildesheim, Germany, 8.5 million starter armatures are produced annually. Each has a winding with 25 formed copper pins. “We produce about 200 million pins a year,” says Daniel Gremmel, production planner at the facility. Pins are made from continuous copper wire that’s cut to length, then molded. “We urgently needed an appropriate measuring system.” The solution is an optical measuring system, TubeInspect HD, from AICON 3D Systems (www.aicon3d.com). “With TubeInspect HD,” Gremmel explains, “we are now in the position to identify the slightest deviation of the pin to its nominal data and correct it. Thus, we can drastically reduce the number of deficient pins, and minimize the distortions in following processes.” The system is also used at Bosch to measure sample parts and to work with engineering to optimize the production processes.
