3R-RBH

3 Rolls Hydraulic Bending Machines

Our 3R RBH hydraulic bending machines are used in the bending process of medium and heavy platinum sheet metal, aluminum, or stainless materials, thanks to their welded strong steel body, hydraulic movement of the bottom and side rolls, and planetary gearbox that is connected to the main engine.

Category: HYDRAULIC BENDING MACHINES

•Steel constructed machine body ST-52
•Well-equipped shafts made from certified steel withSAE 1050 (CK-45)
•Lateral rolls move with hydraulic pistons in orbital way
•Hydraulic Drop-End for easy roll positioning
•Hardened rolls
•Mobile electrical control panel
•Movement and parallelism adjustment of the rollers controlled from control panel
•Two digital reatouts for easy roll positioning of bottom rolls
•Hydraulic balancing system
•Accordance with CE standards
•Two-speed working system (Q275 and above)
•Conical bending system

•Hydraulic lateral side supports for large diameters
•Overhead Crane for large diameters
•Material feed table•Infinitively variable speed of rotation
•Oil cooling system
•Wireless mobile remote control
