AUTOMATIC CONTINUOUS PUNCHING: profiles cut, drilled, milled in one system

Many process steps in one plant

With automatic continuous punching machines, machine and tool merge into a high-performance system with high output and remarkable flexibility. Whether sealing profiles for the automotive industry, applications for furniture, or thermal insulation for buildings or household appliances – complex trimming is often required here. Thanks to the Metzner automatic throughfeed punching machines, processing operations such as contour cutting, drilling and milling can be integrated into a throughfeed system. All these machines store all machining parameters and machine settings in a machining recipe. When starting production, an integrated barcode scanner activates all presettings on the basis of the working papers and simultaneously reports the correct tool and material on the machine display. The barcode also contains the required quantities and lengths. Thanks to well thought-out quick-change systems, tools and materials are generally changed within no more than 30 seconds, minimizing downtimes. Thanks to an integrated tool coding system, the machine automatically checks whether the right tool is available when changing tools.

With a further automation level, material and tool changes are even fully automatic: The machine reads the barcode and the operating personnel press the start button. The rest is done fully automatically and without personnel. If required, fully automatic continuous punching presses are equipped with intelligent length measuring systems and quality monitoring functions that achieve excellent accuracies of approx. 0.1 % (but min. 0.5 mm), depending on the material. Parts that do not meet the specifications are automatically detected and sorted out separately.
