Sheet Metal CNC Tandem Hydraulic Press 400T

400t tandem hydraulic press brake machine

We have 4m, 6m single length for Sheet Metal CNC Tandem Hydraulic Press brake machine 400T. The machine will be suitable for light pole, high mast pole profile forming. Max mild steel thickness can be up to 10mm for 6m x 2 tandem press brake. WE shall use CNC controlled tandem machine for long workpiece bending. It will help customers work high effeciently. while some buyer would like mechanic torsion bar structure machine as tandem. We don't suggest. There is no feedback from each Y1, Y2, there is no possible to make two machine work exactly at same time. so with different working condition, operators will need to adjust machine timely. it will make job slow down and will affect product quality.

TECHNICAL FEATURES

  • Sheet Metal CNC Tandem Hydraulic Press brake machine are controlled by CNC synchronizing system. All machines Y1, Y2 value will transfer from slave CNC to master CNC. Master CNC will calculate and send command to control each unit hydraulic press brake;
  • Normally each unit of Sheet Metal CNC Tandem Hydraulic Press brake machine has same technical parameters. So that we can synchronize the machines easily. While we also can make different parameters machines to be tandem machine by CNC controller.
  • Each unit of tandem hydraulic press brake machine is Electric – hydraulic synchronized design; European CNC controller, with full CNC controlled Y1, Y2, calculation based on material and tool library;
  • Automatic bending procedure optimization by CNC controller, engineer can adjust the steps according to actual design;
  • Y1, Y2 is measured with high accurate optic scalars. Measured signal will be feedback to CNC controller timely.
  • European proportion valves will control left and right cylinder’s movement according to controller’s command.
  • For tandem press brake, we can apply multi axes back gauge. All the machines can work together to finish all work pieces. Also can separately work as single machine.
  • Ram guide is with low friction Polymer wear-resistant materials, which will give long accurate working life;400t-CNC tandem hydraulic press brake
  • Working table is with automatic crowning system. Hydraulic type is for up to 200T-3.2m machines, while wedge structure is applied for bigger machines.
  • For bending force up to 200T, quick clamp for punch is applied. It will be easy handle the up tooling. The clamp has wedge crowning adjust system.
  • Low noise and high efficient gear pump is standard configuration;
  • Ram is with Anti-tilt device for machine protection;
  • Sheet Metal CNC Tandem Hydraulic Press brake Oil tank is with level and temperature indicator.
