MACRI ITALIA PROVAR 5-90 U-D tube bending machine

MACRI ITALIA PROVAR 5-90 U-D tube bending machine, built in Italy in 2010 is used for the fully automatic process of fixed radius and variable radius workpiece bending on two different dies. The machine is characterised by a highly rigid steel structure, modern components and extensive equipment. All 5 axes of the machine (X, Y, Z, B1, B2) are equipped with reliable brushless servomotors in order to provide the user with high dynamics and excellent positioning accuracy when machining tubes and profiles with a maximum length of 5100 mm. The installed state-of-the-art MACRI software allows, among others, to program the positioner force, perform an anti-collision test with 3D simulation, import files from 3D programmes and program the speed of movement of each axis for each bend. The PROVAR 5-90 U-D mandrel bending machine weighs 6000 kg.
