In single-spindle machine models, it is necessary to use the tool change magazine for different milling tools or to change milling cutters manually for each different operation, which leads to time loss in production processes. However, in panel machining centers with dual spindle technology – components, the double milling motor (spindle) integrated side by side on the bridge works in order, and after one of them has finished the work by joining, the second head cutting – sizing is done. In this way, production capacity / speed is increased especially in the production of façade cladding panel systems, and enterprises save time and energy.
