Frequently Asked Questions
Does the WyBend T series support high-strength steel bending?
Yes, with specialized heavy-duty tooling and adjusted bending parameters, the WyBend T series can bend Hardox 450, AH36 and other high-strength steels up to 20mm thickness for ultra-long workpieces.
What is the delivery time for WyBend T series?
Standard tandem models (T16060/T20080) have a lead time of 10-12 weeks, while heavy-duty models (T300100/T400120) take 14-16 weeks including factory testing and synchronization validation.
How often does the tandem system need calibration?
We recommend full synchronization calibration every 6 months under normal operation, or immediately after any machine movement or major maintenance.
What is the energy consumption of the WyBend T series?
The centralized variable displacement pump reduces energy consumption by 35% compared to individual hydraulic systems, with total power consumption of 30-75kW depending on the model and workload.
Can the WyBend T series be operated as individual machines?
Yes, all linked machines can be decoupled and operated independently for smaller workpieces, providing flexibility for mixed production of small and ultra-long components.
What is the installation space requirement for WyBend T series?
The T16060 (6m length) requires a minimum floor space of 8m×4m, while the T400120 (12m length) requires 14m×5m, plus additional space for material handling and maintenance.
How is synchronization achieved between multiple machines?
Synchronization is achieved through a centralized Cybelec DNC 9000T or DELEM DA69T control system, absolute linear scales and unified hydraulic power unit, ensuring all machines move in perfect unison with latency ≤ 1ms.
What is the maximum bending length of the WyBend-T series?
The WyBend T series supports bending lengths from 6m (WyBend T10026) up to 12m (T80080) by linking 2 to 4 individual press brake machines with precise synchronization control.
