The dual-stage precision leveling machine is an advanced processing solution specifically designed for high-precision leveling and stress relief of thin materials such as aluminum sheets, copper sheets, and aluminum-magnesium alloys with thicknesses ranging from 0.1 to 0.6 mm. Its unique structural feature, compared to standard thin-sheet leveling machines, is the inclusion of an additional set of 3 upper and 3 lower staggered leveling rollers, forming a two-stage leveling structure. This design allows the material to undergo two stages of precision leveling, achieving high-precision leveling for thin materials and fully eliminating internal stress, making it the perfect leveling equipment for thin materials with thicknesses ranging from 0.1 to 0.6 mm.

However, due to the specialized nature of this leveling machine, many customers often have no prior experience using it. This article provides a comprehensive guide on how to operate and utilize a dual-stage precision leveling machine effectively, ensuring high-quality leveling results and efficient performance.

Understanding the Dual-Stage Precision Leveling Machine

To achieve the best possible results with the dual-stage precision leveling machine, it’s crucial to understand its operation and techniques. Follow these step-by-step instructions to ensure a smooth and efficient process:

1. Placement and Positioning of the Leveling Machine

After unpacking the dual-stage precision leveling machine, decide on its placement position. Align the center of the leveling machine with the centers of the uncoiler, feeder, and stamping die on the same centerline to prevent material deviation. Based on the actual material thickness and stamping process characteristics (mainly the feeding step of the feeder), determine the final placement position of the leveling machine. Generally, the dual-stage precision leveling machine is placed at a distance of 1.5m to 2m from the feeder. For longer feeding steps, increase the distance to avoid false positive feedback.

2. Verifying Material Thickness

Ensure that the actual material thickness is within the applicable range of 0.1 to 0.6 mm, as the dual-stage precision leveling machine is designed specifically for materials within this thickness range.

3. Checking Roller Alignment

Confirm that the upper and lower leveling rollers of the dual-stage precision leveling machine are at the reference points. These points guarantee complete parallelism, which is essential for achieving optimal leveling results. The machine is factory-tested and set to a scribed adjustment scale display of 5.0, allowing customers to verify its correct position and level.

4. Inching Test Adjustment for Dual-Stage Precision Leveling Machine

Unlike the four-point adjustment of standard precision leveling machines, the dual-stage precision leveling machine utilizes an eight-point system, which results in a different adjustment method. The front section is used for coarse leveling, while the rear section provides precise leveling, suitable for leveling materials with an upward curvature. For practical testing, if the material strip requires upward curvature leveling, the front section may not be necessary, and the upper roller can be raised to use only the rear section. If the material strip requires downward curvature leveling or has unstable curvature, adjust the front section upper roller downward to reverse the material strip curvature, followed by precision leveling in the rear section.

5. Adjusting the Sensor Frame for Automated Production

After confirming accurate leveling results during the inching test, adjust the sensor frame to the appropriate position. When the material touches the sensor rod, the leveling machine will automatically stop. As the feeder pulls the material, the precision leveling machine will automatically run to level and feed the material. Adjust the leveling speed using the speed control knob to match the stamping process for automated production.


By following these steps, operators can effectively utilize the dual-stage precision leveling machine to achieve high-quality leveling results for thin materials. Gaining a thorough understanding and mastering the operational techniques are essential for realizing the full potential of this specialized equipment in various industrial applications. With proper handling and utilization, the dual-stage precision leveling machine can outperform ordinary single-stage thin-sheet leveling machines, providing unparalleled leveling performance.
