High rolling power combined with maximum pre-bending precision: HAV is the series of 3-roll variable geometry bending rolls at the highest level of its category by performance and versatility.
HAV bending rolls designed, manufactured and marketed by Faccin deliver performance equivalent to that obtained with the more expensive 4-roll plate bending rolls and are therefore ideal for medium-heavy duty machining.
HAV series models feature a very fast and secure pre-bending stage, because the plate is never tilted but always parallel to the ground. This allows motorized feeding tables to be used, with automatic centering systems.
Thanks to the special configuration of HAV electronic plate bending rolls, the machine’s 3 rolls move independently – the top roll moves vertically, the lower rolls horizontally – allowing you to adjust, as required, the centre distance between the lower rolls and the distance between the bending points, as is the case on a press brake with variable opening lower die. By reducing to the minimum the centre distance between the lower rolls, the HAV series bending rolls obtain excellent traction of the sheet. In addition, by minimising the length of the straight part, they offer better quality pre-bending. The maximum centre distance between the lower rolls instead, makes it possible to produce a huge rolling capacity.
Thanks to the horizontal position of the cylinders for lower roll movement, HAV 3-roll variable axis bending rolls are equipped with a reduced height work top. No foundations are therefore required, even for bending rolls with capacity greater than 40 mm. All the HAV series 3-roll bending rolls are fitted with the EPS system for electronic synchronised control of roll parallelism within tolerances of less than 0.2 mm, guaranteed over time as they are not subject to mechanical wear or delay of hydraulic drives. The HAV series models are the right solution to bend plates up to 300 mm thick.
