Fontijne Grotnes builds specialised production equipment that can be used in complex manufacturing processes and has been active in the metalforming industry for more than 100 years. Its sizing technologies, consisting of expanding, shrinking and rollforming processes, are a valuable contribution to diverse production processes, to calibrate and form different parts such as rings, cylinders and cones, which require tight tolerances. These processes often eliminate machining and fabricating steps, save time and material and thereby improve operational efficiency and profitability. Fontijne Grotnes expanders and rollformers are widely used to form finely detailed profiles in cylindrical or conical shaped blanks from tubing, pipe or coiled and welded sheet metal. To form a profile the blank is positioned around the collapsed dies of the expander, which have the desired profile. Cone and drawbar are in the extended position. As the drawbar pulls the cone down the inclined surfaces of the cone force the jaws and dies outward. Outward expansion stretches the part past its yield point to the

diagnostics and multiple languages. The interactive touch screen displays absolute (ABS) or incremental (INC) positioning with inch or metric readout. Model TM76 incorporates programmable mandrel positioning with anticipated mandrel retraction, clamping, pressure die and boost die movements. Tailstock Y and B position display resets to zero after each bend for easy setup while maintaining absolute position. Patented by Ercolina, finger style clamping system minimises distance between bends. A heavy, one-piece steel structure improves rigidity and minimises vibration. Ercolina’s tubing benders and fabricating machinery are designed to reliably and accurately produce applications, improving product quality and finish.

ERCOLINA’S TM76 mandrel bender is suitable for prototype or daily production purposes. CML USA, Inc, North American supplier of Ercolina tube, pipe and profile bending and metalworking machinery, has introduced the TM76 with a bending capacity to 3" round tube and capable of bends to CLR as small as 1.5D. This model offers unlimited storage of bend programs, material library and job information with USB. Controls are designed for easy access to manual and auto operating modes, system
