Resource efficiency through lubricant recycling

ABB STOTZ-KONTAKT produces circuit breakers in its highly automated production facility in Heidelberg. During prefabrication, the "frame" component is manufactured for these devices, among other things. This component is for connecting the device when wiring an electrical system. In the punching and bending manufacturing process, steel strip material is processed in six steps: punching, bending, stamping, welding, calibrating and thread forming. In the final machining step, thread forming, not only are high demands placed on work efficiency and quality, particular attention is also paid to maintaining the longest possible service life for the thread forming tools.
