[0002] Galvanized steel strip is a cold-rolled or hot-rolled, long and narrow steel strip that is coated with a layer of zinc to varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. In some usage scenarios, galvanized steel strip needs to be cut into segments, that is, cut into multiple long steel strips. After cutting the galvanized steel strip, burrs will be generated on the upper and lower length edges of its ends.

[0003] The main method for removing the burrs is to grind the end of the galvanized strip close to the side of the grinding wheel by holding the galvanized strip. The grinding stability in this method is poor and the safety is low.
