The 30-roll hydraulic leveling machine features a core of small-diameter precision rollers, making it ideal for leveling ultra-thin metal sheets ranging from 0.5 to 3.0 mm in thickness. Equipped with an independent hydraulic pressure regulation system, it precisely controls the roller gap and leveling pressure to prevent indentations and deformation in thin sheets. The equipment features a dense support roller structure to ensure roller rigidity. For scratch-prone materials such as stainless steel, copper, aluminum, and mirror-finished sheets, it efficiently eliminates internal stress and wave-like warping, achieving a flatness of up to 0.02 mm/m². The machine is compact, energy-efficient, and suitable for batch processing of small electronic hardware and precision sheet metal parts. It supports continuous feeding operations and features a simple user interface. parameters can be retrieved with a single click, resulting in short setup times for changeovers. With a low failure rate and easy maintenance, it can be integrated with small-scale stamping and laser cutting production lines to meet the demand for high-precision secondary straightening of thin sheets. Additionally, it features overload protection and real-time pressure feedback, ensuring stable and reliable operation, making it suitable for flexible production scenarios involving multiple varieties and small batches.
Precision Micro-Pressure Control: Utilizes a closed-loop hydraulic system with an accuracy of ±0.01 MPa to apply gentle and uniform pressure to ultra-thin foil materials ranging from 0.5 to 3.0 mm. This eliminates microscopic lattice stress without causing surface indentations, ensuring defect-free stamping of battery electrodes.
High-Frequency Stress Relief: Small-diameter rollers enable over 20 repeated bends per second, effectively eliminating the “edge waviness” commonly found in thin materials. This high-frequency action reduces residual stress by 98%, which is critical for roll-to-roll processing in the new energy industry.
Soft-Contact Surface Protection: The roller surface is polished and equipped with a “floating” hydraulic support system to prevent roller marks on mirror-finish materials. Surface roughness is controlled to Ra ≤ 0.05 microns, meeting the stringent requirements of the optical and semiconductor industries.
Real-Time Thickness Compensation: Equipped with a laser thickness gauge, the hydraulic system automatically adjusts pressure within 0.02 seconds when material thickness changes. Even with foil thickness tolerances of ±0.02 mm, the dynamic response ensures consistent flatness.

How should I address issues such as sickle-shaped bending or material deviation after sheet metal exits the machine?
Causes include inconsistent left-right roll gaps, tilted roll trains, equipment centerline misalignment, uneven left-right hydraulic pressure, unbalanced pinch roll pressure, off-center feeding, and skewed guide rolls
Solution: Align the roller system parallelism with the machine centerline, adjust the hydraulic balance valves on both sides to ensure consistent pressure on both sides.
What sheet thicknesses can this 30-mm roller diameter leveling machine process?
This machine is suitable for processing thin sheets ranging from 0.5–3.0 mm, as well as precision sheets such as stainless steel, copper, and aluminum. The 30 mm small roll diameter effectively releases internal stress, achieving a flatness of within 0.05 mm/m after leveling.
Is daily maintenance of the equipment troublesome? Is the failure rate high?
This machine features a mature design and is easy to maintain. It only requires periodic checks of the hydraulic oil, cleaning of the roller system, and tightening of components. With proper maintenance, it has a low failure rate and a long service life.
