Teeth can be corrected, so the deformation of cast iron plates can generally be repaired and corrected. But it also depends on the platform material purchased at that time. If the materials meet the national standards, they can be repaired and corrected by mechanical methods. For example, it can be corrected by heating or during heat treatment. Of course, it is best to find a special leaf manufacturer to deal with it. A while ago, I bought a cast iron flat plate from other manufacturers and used it for two years. I entrusted Botou to build a new measuring tool to repair and correct it.
