Four-roll plate roll includes CNC

C Marshall Fabrication Machinery offers the M3015C four- roll plate roll with CNC Touch Command EVO control. Two dragging rolls with hydraulic pinching allow a steady and precise material dragging, the company states. The machine also prebends the leading edge and rolls the body of the part along with the trailing edge in one direction and in one pass. The plate is kept square, without slipping, during both prebending and rolling because of the constant clamping of the bottom and top rolls.

Side roll parallelism is maintained by a torsion bar system that connects both ends of the rolls together, eliminating extra encoders and hydraulic circuits. The side rolls are raised and lowered on planetary swing guides.

The CNC handles a virtually unlimited number of programs and steps per program, and synchronization of movements is automatic.
