ALG System 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. 

Built For Heavy Work

HMB System

Heavy Multiple Bearings

Each bending roll is supported by 4 heavy-duty self-aligning spherical roller bearings (double raw type). Each bearing is over-sized in order to withstand the whole bending load. Thanks to the HMB exclusive design, with four over-sized bearings fitted into a swiveling housing, the roll can freely deflects along its 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 machines reliability and life. Moreover, the multi bearing system with swiveling housing design greatly reduces the maintenance and the need for lubrication (permanent lubrication).

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.
