Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the maximum bending force of this machine? **A**: The bending force ranges from 100 to 4000 tons, depending on the model. The actual force required depends on the material type, thickness, and bend length. Always consult the manufacturer for the specific model's capacity. ### Q: What is the working length of the machine? **A**: The working length, or maximum bendable plate length, ranges from 2000 to 8000 mm. This determines the maximum length of the plate that can be bent in a single operation. Verify the exact working length for the model you are considering. ### Q: What electrical supply is required? **A**: The machine requires a 3-phase, 380 V electrical supply at 50/60 Hz, conforming to IEC 60038. The electrical power consumption ranges from 5.5 to 45 kW, depending on the bending force. Ensure your facility meets these requirements. ### Q: What is the positioning accuracy of the back gauge? **A**: The back gauge positioning accuracy is ±0.05 mm, ensuring repeatable bends. The back gauge range is 0 to 1000 mm. This accuracy is critical for consistent production. Confirm the accuracy with the manufacturer for your specific application. ## 6.
