Nov 27, 2015· If the cobble rate is 0.75 %, then 0.75 % of all billets charged are lost to cobbles. If a mill rolls 640,000 billets per year then it means that 4800 billets are lost. At 1.25 tons per billet the loss in tons is 6000 tons. Hence it necessary that all attempts are to be made in the mill to reduce the cobble rate.

The technology of Ball Screw removes the wobble, dog walking, and inaccuracy that many lead screw and Rack and Pinion drives have. With Rack and Pinion, you have two motors on the Y axis (long axis) with independent gears which allows for your machine to eventually wear unevenly because no two gears will ever wear identically.
