Design Engineering News, Engineering Videos, Engineering Resources - Universal joints help reduce mill vibration

12/8/2015· Two spindles on each mill stand connect the pinion gearboxes to the primary upper and lower work rolls that compress the steel in a cold condition. Over time the surface damage to the steel from the spindle vibration (chatter) caused the operator to either slow the mill down, reducing production by 20% to reduce the vibration, or replace the spindles completely.
