It is widely used in various transmission and conveying systems such as rotary screen printing machines, digital printers, mining conveying equipment, papermaking and packaging machinery.It is usually made of seamless steel pipes, and depending on the process, such as aluminum alloy 6061T5, 304L/316L stainless steel, 2205 duplex stainless steel, steel castings, and solid forged alloy steel cores are used as materials.The production of the roller mainly consists of the first rolling of the roll body, the preliminary static balance, the interference assembly and welding of the shaft head, the fine turning and the fine tuning of the dynamic balance. If the behavioral tolerances such as roundness, cylindricity and straightness are required to be less than 0.2mm, it is necessary to use a cylindrical grinder or a roll grinder for grinding after finishing. If the surface hardness is required, it is necessary to increase the heat treatment process.After the roller is formed, for the needs of anti-rust, anti-corrosion, wear resistance and support, surface treatment or coating such as painting, galvanizing, TEFLON spraying, rubber coating, chrome plating, ceramic spraying and oxidation are also required.(engraved rollers, engraved rollers with goldfish pattern )http://www.hexinmachinery.com/a/Products/Glass_rolling_rollers_and_machinery/Gla/
