mechanical and hydraulic compensate
The great benefit of– mechanical and hydraulic – crowning systems is that operators do not have to be familiar with the bending process in order to compensate for deflection in the press brake. However, hydraulic crowning systems can have major shortcomings in situations where bending accuracy is very important. Due to their lower resolution, hydraulic crowning systems are not able to accurately compensate for deflection in press brakes or locally compensate for vertical deviations (y direction). However, WILA's mechanical crowning system is able to do this: the wedges accurately follow deflection in each run and allow corrections to be made when the load changes. Moreover, local vertical deviations can be compensated by way of transverse adjustment. This makes WILA's mechanical crowning system extremely accurate in all circumstances.
