At Jiuzhong, we are committed to producing highly accurate and efficient metal straightening equipment. The JZ40-Z series NC 4-high roller leveler is one of our most advanced models, ideal for flattening metal sheets with a thickness range of 0.4–3.0mm.

This machine features a 4-high roller structure, with backup rollers supporting the working rollers to maintain pressure stability and minimize deflection. This design allows for consistent leveling across long production cycles, especially when working with high-strength or thin materials.

The JZ40-Z leveler uses NC (numerical control) for automatic roller gap adjustment. With just a few inputs on the touchscreen interface, operators can precisely control roller pressure and positioning. This reduces human error, speeds up setup time, and ensures consistent performance across different batches.

Our JZ40-Z model is ideal for processing punched sheet metal, stainless steel panels, and high-precision stamped parts. Industries such as electrical enclosure manufacturing, appliance production, and vehicle body panel fabrication benefit from the superior flatness this model provides.

The compact but robust frame, together with wear-resistant rollers and electric drive systems, make this machine a reliable tool for both light and medium sheet leveling. Its ability to reduce material distortion and stress improves the quality of downstream operations such as bending and welding.

Jiuzhong has integrated high-performance servo motors and real-time feedback systems into the JZ40-Z leveler to enhance accuracy. The system detects material input conditions and adjusts automatically for optimal straightening — a major advantage for automated production lines.

Choosing the JZ40-Z NC 4-high roller leveler means investing in smarter sheet metal processing. With Jiuzhong's expertise and after-sales support, manufacturers can count on long-term durability and consistent leveling performance.
