Electro-hydraulic servo bending machine or press brake PRH-160/3200

PRH-160/3200 Electro-hydraulic servo bending machine Nominal pressure:1600KN Bending length:3200mm

1. The characteristics

The rack adopts the strengthened rigid steel whole welding structure, which has enough strength and rigidity, also through aging treatment to make sure the overall accuracy of the machine, with good anti-distortion and anti-inclinable capacities.

The thickened workable plate, thickened sliding blocks make the whole machine with good rigidity, with small distortion and good straightness and angle consistency. The worktable uses the electric rod type mechanical compensation worktable to ensure the straightness of the workpiece.
