DC‑220 CNC Notching Channel Letter Bending Machine

Product Introduction

Newin DC‑220 automatic CNC notching channel letter bending machine is high‑end flat‑aluminum processing equipment for signage industry. Equipped with 8‑axis full‑servo control system. It integrates dual‑manipulator alternate feeding, planer slotting, automatic notching, automatic flanging, arc‑forming and automatic cutting‑off. Specially designed for flat aluminum sheet, for mass‑production of notched illuminated letters and large‑height 3D advertising signs. Adopts export‑grade high‑precision encoder and closed‑loop length control system. Key components are hard‑chrome‑plated for wear‑resistance and anti‑corrosion. The control software is simple and user‑friendly.

Key Features

1. Dual‑manipulator alternate‑feeding mechanism: cast‑material clamps deliver strong gripping force, stable feeding without scratching aluminum surface.
2. Double‑blade alternate bending structure, excellent forming quality and high operational stability.
3. Servo planer slotting system with auto depth‑adjustment and auto‑tool‑setting. Hard alloy finished inserts with multi‑tips for rotation‑use, no‑grinding & maintenance‑free, low consumable cost. Ball‑screw plus double‑square‑rail four‑slider transmission provides powerful and stable slotting.
4. 8‑axis high‑power full‑servo drive system, high torque & fast response, greatly improve letter‑making efficiency.
5. Closed‑loop length control with export‑grade encoder, software‑controlled length error ≤0.1 mm.
6. Hard‑chrome‑plated critical machine parts, wear‑resistant and anti‑corrosive to extend service life.
7. Intelligent automatic notching function: software recognizes graphic angles for auto notching; auto notching at arc positions followed by automatic flanging for notched‑letter craft.
8. Automatic cutting‑off function: material gets cut off automatically once one letter set is finished.
9. Intuitive & easy‑to‑learn operation software.
