Investing in a high-precision hydraulic leveling system is the most effective way to achieve perfectly flat, stress-free metal sheets that perform flawlessly in downstream fabrication. Suzhou Jingshi Intelligent Equipment Co., Ltd. (JINGSHI) designs advanced leveling equipment that eliminates persistent material defects like coil set, crossbow, twist, and camber. By utilizing high-density roll configurations and dynamic hydraulic control, our machines deliver precise alternating bending cycles. This guarantees superior flatness and comprehensive internal stress relief, ensuring your sheets remain completely stable during critical subsequent processes like laser cutting, stamping, or robotic welding.
Our hydraulic levelers easily handle demanding materials, including high-strength steel, stainless steel, aluminum, and copper. We combine massive structural rigidity with fine hydraulic adjustments, providing metal processors with the consistency needed to meet strict manufacturing tolerances, ultimately improving overall product quality and drastically reducing material waste.
The true core of a JINGSHI hydraulic leveling machine lies in combining the powerful driving force of our hydraulic systems with the absolute precise control of our CNC architecture. The machine operates by using a hydraulic power unit to deliver high-pressure oil, which drives robust hydraulic cylinders to apply immense, uniform, and infinitely adjustable pressure to the leveling rolls.
Simultaneously, the CNC system acts as the “brain” of the operation. It utilizes precision servo valves to monitor and adjust the movement of each hydraulic cylinder in real time, establishing a flawless closed-loop control of both pressure and position. This integration of power and precision allows the hydraulic system to easily tackle ultra-thick plates and high-strength materials that conventional mechanical equipment struggles with. Meanwhile, the CNC system maintains remarkable leveling accuracy within ±0.01 mm/m, or even at the micrometer level.
Because of this irreplaceable adaptability to special materials and demanding precision requirements, these high-end finishing machines are the premier choice for the heavy equipment manufacturing, construction machinery, rail transit, aerospace, and defense industries—excelling in tasks like the precision leveling of aircraft structural components and marine thick plates.
Selecting the optimal roller configuration is critical for achieving precise performance across different material types. We offer a robust lineup of leveling machines tailored to your specific material demands. Material thickness, yield strength, and required precision dictate your ideal configuration.
| Model / Roll Configuration | Target Sheet Thickness Range | Primary Application & Materials |
|---|---|---|
| 30-Roll Configuration | 0.5 to 3.0 mm | Ultra-thin sheets, sensitive surfaces, non-ferrous metals |
| 40-Roll Configuration | 0.6 to 4.0 mm | Medium-to-thin sheets, general fabrication job shops |
| 50-Roll Configuration | 0.8 to 5.0 mm | Standard industrial sheets, carbon steel, and stainless steel |
| 60-Roll Configuration | 1.0 to 8.0 mm | Medium-to-heavy gauge structural plates, high-load processing |
Our 30-roll Hydraulic Leveling Machine is specifically engineered for ultra-thin metal plates. Delicate materials require high-density, precise roller configurations. By utilizing closely spaced, small-diameter rolls, the system creates frequent alternating bending cycles. This precise action relieves internal stress without inducing surface stretching or wave-edge defects, making it the perfect solution for electronic components, decorative panels, and precision appliance parts.
For sheet metal job shops requiring versatility, our 40-roll Hydraulic Leveling Machine serves as a balanced workhorse. This configuration accommodates a broad range of standard-to-thin gauges. It offers the structural rigidity needed to level tougher alloys while maintaining micrometer-level precision for thinner sheets, making it ideal for contract manufacturers processing diverse daily material batches.
Our 50-roll Hydraulic Leveling Machine is designed for continuous, high-load industrial environments. The system boasts exceptional structural frame rigidity, ensuring absolute leveling consistency even during non-stop production shifts. It successfully targets standard gauge carbon steel, stainless steel, and aluminum plates, guaranteeing uniform flatness across the entire sheet width.
When dealing with heavy marine structural plates, aerospace components, and stubborn shape defects, our heavy-duty Hydraulic Leveling Machine provides massive roll torque. It delivers the high-yield hydraulic cylinder force required to force deep plastic deformation. This neutralizes complex residual stresses in thick plates, ensuring your heavy parts remain perfectly flat during subsequent welding or heavy machining.
True precision in sheet metal processing requires complete internal stress relief. When metal sheets are rolled, coiled, or slit, they retain significant residual stresses. If left untreated, the material will warp or twist when heated by a laser cutter. Our levelers resolve this issue using highly controlled, alternating bending cycles that stretch the material fibers past their yield point. This effectively neutralizes residual stresses, guaranteeing your parts remain dimensionally stable.
To support this intense mechanical process, we utilize a high-rigidity multi-layer roller structure (available in 4-to-6-layer layouts) that prevents roller deflection under immense hydraulic pressure. Additionally, custom roll surface treatments—including hard chrome plating and non-marking polyurethane options—combined with intermediate support rolls, ensure sensitive materials like aluminum and mirror-polished stainless steel are leveled with zero surface damage.
Traditional leveling equipment often acts as a factory bottleneck, requiring skilled operators to spend 20 minutes manually adjusting roll gaps and recalibrating. JINGSHI eliminates this downtime with our smart CNC control system and user-friendly touchscreen interface. Featuring an integrated recipe database, our advanced controller can easily store and instantly recall precise positioning profiles for various material types, thicknesses, and widths.
Setup and material changeover times drop from 20 minutes to under two minutes. This 90% reduction dramatically increases overall equipment effectiveness (OEE), allowing manufacturers to handle small-batch custom orders without sacrificing daily throughput. Even less-experienced operators can run our equipment with micrometer accuracy, reducing your factory's reliance on specialized labor.
Depending on your facility layout and production volume, JINGSHI offers two distinct pathways to incorporate our precision technology into your workflow:

The hydraulic power unit provides the massive force needed to bend thick and high-strength metals, while the CNC system uses precision servo valves to continuously monitor and adjust the cylinders. This creates a closed-loop control system that maintains a leveling accuracy of up to ±0.01 mm/m.
Our equipment subjects metal plates to controlled, alternating bending cycles. We stretch the outer material fibers past their elastic limit, then gradually reduce the bending intensity to neutralize internal residual stresses. This guarantees your processed sheets will not warp during high-heat processes like laser cutting.
Because of their ability to process high-strength materials with micrometer-level accuracy, our machines are heavily utilized in the aerospace, defense, marine, rail transit, and heavy construction machinery industries, where structural integrity and perfect flatness are non-negotiable.
Selection depends entirely on your material thickness range and stiffness. The 30-roll configuration is engineered for ultra-thin sheets (0.5 - 3.0 mm) using closely spaced rolls to avoid wave edges. Conversely, the 60-roll machine provides massive hydraulic force to level heavy-gauge structural plates up to 8.0 mm.
