The Powerful and Reliable Choice
Full Frame Extended Design
Parmigiani plate rolls have the most heavily sized frame you can find in the market. Unlikely slim frames covered with thin thickness plates that you can find on all machines in the market, makes our frame design look definitively oversized.The exclusive full frame design withstands all bending forces and guarantees stiffness and performance throughout years of service.This unique machine frame, with extended design for added rigidity and strength, are welded fabrication. After welding all frames are stress relieved and then machined on CNC milling machines

(Anti-friction Linear Guides)
• No friction - less than swing design
• Direct load to the plate
• Less vertical power on top roll
• Lower bending diameter
The linear guide design is the only system that can grant the necessary machine stiffness and the perfect geometry for all kind of bending operations. The linear design allows a compact geometry of the machine ("minimum centerline distance between the two side rolls", impossible to obtain with the swinging design) that is essential for bending precision and accuracy. The linear design allows you to work in the best and ideal geometrical conditions when rolling high yield strength materials, reducing the shell spring back reopening effect and obtain a much smaller bending diameter when compared with the swinging design
• Heavy Duty HMB Exclusive Design
• Supports Cone Rolling
• Permanent Lubrication
Built for Heavy Work HMB System
Heavy Multiple Bearings
More power - More torque HTT System
(High transmitted torque)
Each bending roll is supported by 4 heavy-duty self-aligning spherical roller bearings (double raw type). Each bearing is oversized in order to withstand the whole bending load. Thanks to the HMB exclusive design, with four oversized bearings fitted into a swiveling housing, the roll can freely deflects along it’s full width during the rolling process. This guarantees an optimal distribution of the load on the supports even during the cone rolling process and increases the machine's reliability and life. Moreover, the multi bearing system with swiveling housing design greatly reduces the maintenance and the need for lubrication (permanent lubrication).
Friction free - Maintenance free AST System
Anti-friction sliding technology
Each Rolls support is machined with anti-friction material in the sliding area. This system drastically reduces the maintenance and sliding friction, less than in a planetary machine.
The rolls driving is realized by independent hydraulic motors via planetary gear transmission directly coupled to each driven roll. The independent rolls hydraulic drive assures and automatic speed compensation between the top and lower rolls and an optimal distribution of the torque on each roll during the working phase. The HTT system allows the best plate feeding and the highest driving torque of any competitive machine. A winning combination for those looking for performance of the highest level.
VBH Options
Great Options and Accessories
Our Parmigiani VBH has a standard package of features that usually are not available even as options in other machines (like our FACILE,
i-Diagnostic, calibration working mode, Servo-dynamic Active Control with infinitely variable positioning speeds of the bending rolls and active pressure control of the lower roll...) our R & D department has designed a wide range of accessories for special bending applications, like the Hydraulic cambering device for central lower roll with variable intensity for working with thin and long plates, gantry loaders, unloading devices etc. in order to increase productivity and quality of finish for special materials.
