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.
