The invention discloses a corn husking roller and a processing method thereof. The processing method comprises the following steps: S1, performing de-stressing thermal treatment on a tube blank; S2, using a chain drawbench and an assorted first mold to perform first cold drawing on the tube blank; processing a plurality of continuous spiral and protrusive ridges on an external surface of the tube blank; S3, using the chain drawbench and a second mold to perform second cold drawing on the tube blank on which the spiral and protrusive ridges coldly drawn; and processing a plurality of grooves on the spiral and protrusive ridges in the axial direction of the tube blank. The method is characterized by high production efficiency and ability to realize mass production; and the manufactured husking roller is anticorrosive and has high usage rate.
