DEA 4R

4 rolls machine very sturdy and accurate, with lateral rolls that move on rectilinear guides.

Its strength is totally assisted by a perfect precision, indeed, thanks to its electronic system designed especially for the work of this type of machine, DEA 4R ensures maximum precision both in the pre-bending and in bending phases.

All the operations of the machine are leaded by the most recent model of PLC and on customers request, we can provide a last-generation and knowable user CNC.

«Classical» 4 rolls plate bending machine:

  • Thanks to a very strong design and to the side rolls with linear movement (A.K.A. Pyramidal style) this plate bending machine is very easy to use and allows a great variety of control, from the manual (standard) to NC or CNC for repetitive applications such as Stainless Steel, that is the main material with even mechanical properties.
  • The plate is pinched between the Top and Pinching roll in every production step.
  • Thanks to the Pinching Roll this kind of plate bending machine can work from thin plates up to thicker one, depending on the mechanical light between Top and Pinching rolls.

STANDARD EQUIPMENT
