Pictures of the round bar straightening and polishing machine. This round bar straightening andpolishing machine is used to straighten the metal rod bar. The rollers of this round barstraightening and polishing machine are interlaced, catty-cornered and symmetrical distributed, when the rod bar is notched in the round bar straightening and polishing machine, it will be rotated forward and bended repeatedly to realize straightening, after straightening work finished, the material enter into to polishing work, thenget the required polish qaulity. From the round bar straightening and polishing machine, both complete the straightening and polishing work at the same time and get good qaulity, the round bar straightening and polishing machine will wast time and labor, so the straightening and polishing machine is very efficiency and need to be owned. The round bar straightening and polishingmachine has compact construction, straightens the metal rod rapidly and precision.
