MACRI ITALIA PROVAR 6-45 U-D bending machine was manufactured in 2019
in Italy. The fully automatic mandrel bending machine is used in the
process of machining tubes and profiles with a maximum diameter of 45
mm in 6 numerically controlled axes (X, Y, Z, B1, B2, A). Excellent
process stability and workpiece quality, with the possibility of
bending standard and variable (free) radiuses, are guaranteed thanks
to the robust steel construction, the moving head with high-strength
gears and the equipping of all machine axes with brushless
servomotors.
The MACRI PROVAR 6-45 U-D tube bending machine is controlled using
state-of-the-art MACRI software with the ability of importing files
from 3D programmes and performing an anti-collision test with 3D
simulation, programming of positioner force and automatic mandrel
lubrication and many other useful functions. The total weight of the
machine is 4200 kg.
