For our customers demanding rigidity and accuracy we deliver with the cast-iron Super Duty Series of CNC router from C.R. Onsrud. When you cut man-made materials most of the time, our heavy, Pro Series machines are fully capable of getting the job done. But, if your primary materials are solid wood or non-ferrous metal (both of which create significantly more vibrations), then you definitely need the additional dampening ability of a cast iron bridge . The inherent properties of cast iron bridge construction deliver a greater ability to absorb and dampen cutting vibrations generated, which helps to minimize the amount of vibration transferred to the spindle. We believe you'll quickly discover the cast iron frame design of the "Super Duty" Series simply outperforms the competition. Overall weight, mass, and rigidity of the machine promotes faster feed rates, deeper per pass cutting, better finishes, longer tool life and less maintenance over the lifetime of your machine’s operation. With the Super Duty Series fixed bridge positioned across the width of the twin table configuration – the machine footprint uses half the floor space of a typical "fixed gantry" machine. This design allows the ultimate in operator flexibility as tables can be run, loaded and offloaded independently without interrupting the adjacent table’s cutting cycle. This platform can also operate in slave mode with the two tables electronically locked together for the occasional large part which needs span across both tables. The flexibility of having 100% cutting time (pendulum processing) for your daily production, combined with the larger part capabilities ensures the Super Duty Series will always be making you money.
