The correct way to grind a roll perfectly straight and round we have demonstrated by actual experience is to have the grinding wheel stationary and traverse the work before it, care being taken to have all the parts of machine as rigid and free from jar or spring as is possible.
Edwin Harrington Roll Grinding Machine, pages 56-57
This machine is designed for the accurate grinding of rolls, 16 inches diameter, any required length. As shown in photograph, the work is placed in housings on movable table and travels hack and forth in front of grinding wheel; the bed is strongly ribbed and heavy; the table, which is moved by screw to insure smoothness and steadiness of motion, has self-oiling guides, running in bed; the traverse of roll front of wheel is automatic. Rolls ground on this machine can be used for rolling the thinnest material without wrinkling.
