Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What materials can be rolled with this machine? **A**: The machine is designed for metal plates, typically steel. The roller material is 42CrMo per GB/T 3077, but the actual workpiece material must be within the machine's capacity. Confirm with the manufacturer for specific material grades. ### Q: What is the maximum plate thickness and width? **A**: The reference ranges are 4–25 mm for thickness and 1000–4000 mm for width. These are general ranges; the exact capacity depends on the specific model. Always verify with the supplier. ### Q: Can the machine produce conical shapes? **A**: Yes, the machine can form cones by adjusting the roller angles or using a cone-bending attachment. However, the capability depends on the machine design. Consult the manufacturer for conical forming options. ### Q: What maintenance is required? **A**: Regular maintenance includes checking hydraulic oil levels, inspecting rollers for wear, and ensuring proper alignment. Follow the manufacturer's maintenance schedule. Overloading or improper use can cause damage. ## 6.
