CNC Folding Machine, commonly known as a CNC Press Brake, is a state-of-the-art sheet metal forming machine that utilizes a Computer Numerical Control system to automate the bending process. It applies precise force to a metal sheet, clamped between a matching punch and die, to create accurate and consistent bends at predetermined angles.
Unlike manual machines, the CNC Press Brake guarantees high repeatability, efficiency, and complexity in production. The operator programs the desired part geometry into the control system (often using offline simulation software). The machine then automatically adjusts critical parameters like the back gauge position, ram stroke, bending speed, and tonnage, ensuring each bend is executed with perfect precision. This makes it an indispensable piece of equipment for modern metal fabrication shops.
Key Features
- High Precision & Repeatability: Equipped with high-resolution linear scales on the Y-axis for real-time closed-loop feedback, ensuring consistent bend angles and part dimensions, batch after batch.
- Superior Efficiency: Automated multi-axis back gauge, fast approach/return speeds, and a large program storage capacity drastically reduce setup and cycle times, boosting overall productivity.
- User-Friendly Operation: Intuitive CNC graphical interface supports 3D simulation, offline programming, and direct DXF file import, minimizing operator errors and training time.
- Robust Construction: Fabricated from high-strength steel plate with normalized treatment for superior stability and long-term accuracy under heavy loads.
- Advanced Crowning Compensation: Automatic deflection compensation system (hydraulic or mechanical) ensures uniform bending angle across the entire length of the workpiece.
- Enhanced Safety: Standard safety features include a laser guarding light curtain, two-hand operation buttons, and mechanical locks, ensuring a safe working environment.
- Energy Saving: The electro-servo drive system (if applicable) consumes significantly less power during idle and setup, making it an economical and environmentally friendly choice.
