Hydraulic 4-Roll Plate Bending Rolls
 

Double Pinch
 
 

4-Roll Plate Bending Rolls provides the outstanding performance, reliability, and quality features to reach the requirements of high precision and high production rates.  The machine has one fixed top roll and 3 pcs independently adjustable bottom rolls; under this roll arrangement, it is combined with the clamping and prebending advantages of 3 roll single pinch and double pinch machine.Furthermore, itĦĤs the best style mass production machine to do with CNC control, because once the material is clamped by the top and the central bottom rolls can get a fixed reference point for computer calculation.This type of machines is most suitable to do the job from 6mm to 75 mm thickness, with 1500 mm to 6000mm width.
