How to deal with galling

Fabricators who bend a lot of galvanized material are familiar with galling, the buildup of zinc deposits on the bending radii of press brake dies. Galling looks a lot like small scratches on the die's bending radii, and it introduces multiple challenges into the bend operation:

Decreased accuracy

Part marking

Trapping the part in the V-groove in cases of excessive buildup

Galling can occur so quickly that operators often have to clean tools after just 10 runs, which is a massive hindrance to their workflow and productivity. Fortunately, you can reduce galling by regularly cleaning your tools or investing in tooling with a protective coating.
