Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the maximum plate thickness this machine can handle? **A**: According to the directory data, the maximum plate thickness is 10 to 40 mm. However, thicker plates require higher bending force and may reduce width capacity. Always confirm the exact capability with the manufacturer for your specific model. ### Q: Can this machine bend plates without heating? **A**: Yes, it uses cold-forming process, applying controlled pressure to deform the plate plastically without heating. This preserves the material's integrity and is suitable for high-strength alloy steel and hardened tool steel. ### Q: What control system does the machine use? **A**: The machine is equipped with a PLC + HMI control system, allowing automated and repeatable bending operations. This facilitates precise adjustment of roller positions and speed for consistent results. ### Q: What are the power supply requirements? **A**: The standard power supply is three-phase 380 V AC ±10%. Other voltages may be available on request. Verify the electrical specifications with the manufacturer to ensure compatibility with your facility. ## 6.
