Aluminum guide roll structure and characteristics aluminum guide roll is also called aluminum alloy guide roll, is through the selection of high-quality aluminum alloy material (6063-T5) , through the mold into the pipe type (from external diameter 30 mm ~ 220 mm) various specifications, there are reinforced structure, high strength. And the use of precision equipment and special tools for surface finishing, so that the surface smooth, coaxial degree of 0.02 mm, the whole shaft by computer balance correction within 2 g, shaft end with special technology and with imported bearings, at high speed, can easily run. According to the different needs of the industry, its surface can be special treatment: sandblasting, mesh, Teflon and special hardening treatment HV700, so that it has good scratch resistance, wear resistance. Star source aluminum guide roll has high strength, small resistance, light weight, flexible rotation, no rust, wear and corrosion resistance, especially suitable for printing, packaging, plastic, electronic batteries and other precision machinery industry and all kinds of coil processing industry.
