Drum production the beginning of the roller body static equilibrium, the beginning of the school, the first axis interference assembly welding process composed of fine cars and fine school balancing. Acts of tolerance, such as roundness, cylindricity and straightness requirements in 0.2mm or less, you need to finish turning cylindrical grinder roll grinders grinding processing. Surface hardness is required, you need to increase the heat treatment process. Roller forming, for rust and corrosion, wear and support needs, but also surface treatment or coating such as painting, galvanizing, TEFLON coating, rubber-coated, chrome, ceramic coating, and oxidation processes.
