Hydraulic Tandem Press Brake

Send Message Request a Quote

The hydraulic tandem press brake combines two sets of WC67Y series hydraulic press brake together, and an interlock device is also applied. These two metal bending machines can work synchronously to bend ultra long workpieces, and they can also run separately to enhance the utilization rate. The hydraulic tandem press brake has an optional deflection compensation device to improve bending precision.

As a sheet metal processing solutions provider, we design this range of hydraulic bending brake into variety of models to suit varied application demands. The detailed specifications are listed below.
