The 3HBR Haco Plate Bending Roll Machines are made of high quality forged steel, induction tempered and hardened and the rolls are polished after hardening. Special rolls are also supplied for certain jobs upon request.
Double spherical roller bearings are used for the rolls in stead of bushings to eliminate bushing tolerances and friction which results in energy loss.
The bearings are pre-lubricated and protected by a special washer which doesn't need any lubrication for the entire life of the machine.
The hydraulic motors are connected together with planetary gear drives directly on the rolls. This has the advantage of a very efficient power transmission from the motors to the rolls without secondary transmissions and clutches. This system offers the best torque under every work condition.
The parallelism of the rolls are controlled by massive torsion bars. We eliminate parallelism problems often found on electro hydraulic and electronic systems. This system also gives you the possibility of tilting the rolls for cone work and return to the initial position in a couple of seconds.

As world leader in sheet metal working machines, Haco offers a complete range of reliable, high-precision machines and the software that goes with it. As an absolute specialist, we can provide a customized solution for every specific situation. Originally famous for our sheet metal and woodworking machines, HACO has become so much more than just a manufacturer of punching machines, bending machines and shears. Since the mid-nineties,
HACO has evolved into a company that produces not only sheet metal machines, but also larger and more complex machines, like machining centers and lathes.
Our investments in a local presence should also tell you how important service continuity over the long term is to us. Even if your equipment needs re-engineering or retrofitting after more than twenty years of service, we are always where you need us.
