MACRI ITALIA PROVAR 6-45 U-D bending machine

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 CNC 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.
