Does Leveling Speed Affect Flatness and Accuracy?
The relationship between leveling speed and the accuracy of a material leveling machine is often questioned by customers and technicians. A common belief is that slower leveling speeds result in higher accuracy (flatness), while faster speeds lead to poorer flatness. This article aims to debunk these myths through a series of experiments, ultimately determining the impact of leveling speed on material flatness and accuracy.
Investigating Sheet Material Leveling
This experiment focuses on sheet materials measuring 300mm long × 300mm wide × 1mm thick, with an initial flatness of about 3mm. These aluminum sheets are tested on a 400mm wide precision leveling machine at various speeds.
A. Medium Speed Leveling
The initial test utilizes a medium speed setting, resulting in a post-leveling accuracy (flatness) of 0.08mm.
B. High-Speed Leveling
The leveling machine’s speed is increased for the next test, yielding a leveling accuracy (flatness) of 0.08mm. This result shows that higher speeds do not negatively affect material flatness.
C. Low-Speed Leveling
Finally, the leveling machine’s speed is reduced, causing the material to become stuck and triggering an alarm. After adjusting the speed to a functional level, the flatness remains at 0.08mm.
This experiment demonstrates that the speed of a material leveling machine does not significantly impact the leveling accuracy of metal sheet materials.
Examining the Leveling of Short Strip Plates
In this experiment, three aluminum plate segments measuring 300mm wide × 1mm thick and 1000mm long are tested. The results show no correlation between leveling speed and the flatness of short strip plates.
Analyzing Continuous Stamping Strip Leveling
This experiment assesses the leveling of continuous long strip materials at varying speeds.
A. Normal Stamping Speed
The flatness of the products remains satisfactory at standard stamping speeds.
B. Reduced Stamping Speed
Lowering the speed causes the plate materials to stretch and deform.
C. Increased Stamping Speed
Higher speeds result in material deformation due to inertial impact and excessive curvature in the waiting area. This issue significantly impacts post-stamping products, leading to a high rate of defects.
Unraveling the Truth About Leveling Speed and Accuracy
The experiments conducted in this study reveal that the speed of a material leveling machine does not significantly influence the leveling accuracy (flatness) of leveled products. However, external factors can impact the final products. In cases where processing time is not a priority, operating the material leveling machine at medium speed is recommended, as it reduces stress on the machine and extends its service life.
