CNC Electromechanical Round Bending Machine Prinzing RBA 42/53

CNC Electromechanical Round Bending Machine Prinzing RBA 42/53


Prinzing RBA is part of the 4-roll round bending machine series by Peter Prinzing. This model is designed for high-precision bending of sheet metal into tubes or tube segments for the ventilation, piping, and other industries where surface quality and diameter accuracy are paramount. Thanks to its automation and programmable control, this machine reduces manual operations and increases the speed of the production cycle. The Prinzing RBA is an excellent choice for those seeking a balance between precision, speed, and automation in thin-sheet processing. Its 4-roll configuration, NC control, large program memory, and extensive options allow the machine to adapt to various tasks: from ventilation ducts to formed tubes and housings.

Features and Advantages

  • 4-Roll Configuration: Four rolls made of high-quality steel, capable of handling various material thicknesses with minimal flat ends.

  • Motorized Stepless Positioning: Precise adjustment of the rolls to ensure bend accuracy and minimize deviations.

  • Automatic Material Thickness Adjustment: Adapts the machine to different materials without the need for manual fine-tuning.

  • Touchscreen NC Control: Intuitive interface with program memory capable of storing up to 200 programs with 50 steps each.

  • Data Protection: Program preservation during power outages and password protection for critical parameters and settings.

  • Compact Maintenance-Friendly Design: Easy access to working parts and minimal space requirements for servicing.

Standard Equipment

  • 4 rolls with high-resistance steel coating.

  • Motorized roll positioning and thickness adjustment.
