ANTARA CNC RB25 / 4A

Aluminium Processing Range

CNC Profile Roll Bending Machine

ANTARA Series

ANTARA CNC RB25 / 4A

The DMAS Profile Bending Machine is engineered for precision forming of metal profiles across a wide range of cross-sections and materials. Using servo-driven rollers, photoelectric positioning, and CNC-controlled feed mechanisms, it delivers consistent, repeatable bending performance with exceptional accuracy.

Operating under the three-point rounding principle, the machine automatically adjusts roller displacement via servo control to form profiles into the desired radius in one or multiple passes. The entire system is fully synchronized through a CNC control unit that manages roller motion, feed rate, and bending pressure under a closed-loop system, ensuring high thrust, precision, and reliability.

Technical Features

Multi-Axis Servo Control

Equipped with 3 sets of servo-driven rollers, 2 lifting rollers, and a servo-controlled feed spindle for precise bending operations.

Automatic Photoelectric Positioning

Ensures accurate profile alignment and consistent bending results during every cycle.

Three-Point Rounding Principle

Automatically adjusts the intermediate pressure roller to achieve the desired bending radius with high repeatability.

CNC Intelligent Control

Monitors and synchronizes roller speed, feed length, and displacement to ensure smooth, coordinated motion across all axes.

Closed-Loop Feedback System

Guarantees stable thrust and high bending precision, even under continuous heavy-duty operation.

Versatile Profile Compatibility

Adaptable roller sets accommodate various cross-sections and materials including aluminum, steel, and stainless alloys.

High-Accuracy Encoder System

Measures feed length and rotation in real-time to automatically match linear velocities of the rollers.

Single or Multiple-Pass Forming

Capable of bending profiles to the desired radius in one or several forming cycles depending on material and geometry.
