At Ohio Valley Manufacturing, we understand the importance of proper material preparation. To ensure that steel blanks are flat enough for processing, the material is run through a leveling or flattening machine. This leveling process uses rollers to gradually flatten the material to a uniform thickness, hence roller leveling. We utilize a Hammerle Leveling Machine to complete the roller leveling process.
We chose the Hammerle machine because it can flatten blanks down to 0.005 inches. This range of specs allows us a wide variety of flatness to. Because we are a full-service fabricator specializing in heavy gauge stamping and precision blanking, it is important that we can prepare blanks to meet any customer’s specifications.
In addition to creating a flat metal blank, leveling also creates a ripple-free surface and neutralizes internal stresses that could cause twisting and bowing when the material is stamped. These stresses are tensions within the material that work against each other to move in different directions, which causes a twisting or bowing effect that can distort the stamped components. By running the metal through the leveling process, the material is stretched, releasing the tensions and making the material more predictable.
Roller leveling offers many benefits when compared to other types of methods. It is a simple and quick way to achieve flat parts. Our capabilities enable us to level multiple grades of steel, stainless, and aluminum that range from 0.020 inches up to .250 inches. The Hammerle machine uses 19 rollers to process blanks up to 29 inches wide with a minimum length of 4 inches.
To serve our diverse customer base, we take all the necessary procedures to continue to deliver the highest quality parts our customers expect. Investing in roller leveling equipment and expertise enables us to maintain our top-quality manufacturing operations.
