The production of the bending machines includes a vast range of machines capable of covering the many needs of the bending sector. The range includes hydraulic and electromechanical machines with the application of several control solutions from manual to numerical. The machines are made up of a robust cast iron structure, shafts in rectified steel, mounted on conical bearings all driven by motor reducer and tempered steel gears. The increase in bending is given by the lower rollers worked, depending on the version, by hydraulic cylinders, motor reducers or manually by endless screws. This characteristic is different in the range CR125-6, where the increase in bending is made by the descent of the central roller. The side straighteners in rectified steel are mounted on spherical heads and can be regulated independently.
