The Model 30 Series CNC Precision Leveler, developed by Suzhou Jingshi Intelligent Equipment, represents a significant advancement in metal sheet flattening technology. This series is engineered for high-precision applications involving narrow-width metal strips and thin plates. At its heart is a robust 30mm diameter roll system and a sophisticated 21-roll configuration, which work in unison to deliver exceptional flatness.
A key feature of this series is its advanced PLC Control Panel. This intelligent interface allows operators to input material parameters directly, and the machine automatically adjusts the roll gap and pressure with high precision. This digital control eliminates manual guesswork, ensures repeatability, and significantly reduces setup time. The Model 30 series supports a wide range of standard working widths, including 400mm, 600mm, 1000mm, 1300mm, 1600mm, 1900mm, and 2100mm, providing versatile solutions for various production needs. It is designed to process materials with a rated thickness of 0.5-2.0mm and a maximum thickness of 4.0mm, achieving a remarkable leveling precision of 0.05-0.1mm.
The integrated PLC control system is the brain of the Model 30. Operators can input material specifications (thickness, width, yield strength) via a user-friendly touchscreen. The system then automatically calculates and adjusts the leveling parameters, including the roll gap and pressure. This ensures that every piece is processed with the optimal settings, guaranteeing a consistent flatness of 0.05-0.1mm and virtually eliminating human error. This level of automation is crucial for maintaining high-quality standards in modern manufacturing.
Featuring 21 work rolls with a 30mm diameter, this leveler applies the Bauschinger effect with high frequency and diminishing intensity. As the metal sheet passes through, it undergoes a series of alternating bends that systematically reduce and eliminate internal stresses, coil set, crossbow, and edge waves. This results in a perfectly flat, stress-relieved product that is ready for subsequent processes like laser cutting, welding, or stamping without distortion.
Unlike standard levelers limited to a single width, the Model 30 series offers exceptional flexibility. It is available in standard working widths ranging from 400mm to 2100mm. This allows manufacturers to choose the perfect machine size for their specific product line, whether they are processing narrow components for the electronics industry or wider sheets for general fabrication. This modularity makes it a future-proof investment.
The leveling line speed is fully adjustable from 1 to 10 meters per minute. This variable speed control allows operators to optimize the process based on material type and thickness. Thinner, more delicate materials can be processed at slower speeds for maximum precision, while standard materials can be run faster to boost productivity. This adaptability ensures efficient operation across a diverse range of jobs.

In the electronics industry, even the slightest material warp can lead to assembly failures. The Model 30 series is perfect for leveling the thin metal sheets (0.5-2.0mm) used in chassis, heat sinks, shielding, and connector parts. Its high precision ensures these components are perfectly flat, which is critical for automated assembly lines and ensuring the reliability of the final electronic product.
For job shops and fabrication centers, material flatness is paramount before laser cutting. Warped or stressed plates can cause the laser head to lose focus or collide with the sheet, leading to costly scrap and machine downtime. By feeding pre-leveled material from the Model 30 series into a laser cutter, manufacturers can guarantee clean, precise cuts and significantly improve material utilization and overall process efficiency.
The automotive and stamping industries rely on flat, stress-free blanks to produce high-quality parts. The Model 30 series effectively flattens coiled steel or aluminum before it enters a stamping press. This prevents issues like wrinkling, tearing, or inconsistent dimensions during the forming process, ensuring that critical safety and structural components meet stringent quality specifications.
How does the PLC control system simplify the operation compared to a manual leveler?
The PLC system automates the most critical and difficult part of leveling: setting the roll gap. Instead of relying on an operator's experience and manual adjustments, you simply enter the material's thickness and type into the touchscreen. The system then automatically positions the top roll assembly to the precise gap required. This not only guarantees consistent, high-quality results from the first piece to the last but also drastically reduces setup time and the skill level required to operate the machine effectively.
We process various materials with different yield strengths. Can this machine handle them all?
Yes, the Model 30 series is designed for versatility. While the standard parameters are based on Q235 steel, the CNC control system allows you to compensate for different material properties. For higher strength materials, the system can apply greater leveling pressure to achieve the same plastic deformation. The robust 21-roll design and powerful drive system provide the necessary force to effectively level a wide range of metals, including cold-rolled steel, galvanized steel, aluminum, and stainless steel, within its specified thickness capacity.
Our production line is partially automated. Can this leveler be integrated with other equipment?
Absolutely. The Model 30 series is designed for seamless integration into a complete processing line. As indicated by the optional accessories, it can be equipped with powered or unpowered roller conveyors for smooth material infeed and outfeed. It can also be integrated with decoilers at the front and cutting lines (hydraulic, mechanical, or laser) at the end to create a fully automated "coil-to-cut-part" production cell, significantly boosting your overall throughput and reducing manual handling.
