What’s the matter with the slow down speed of the press brake?

Normally, the press brake machine has an empty stroke. When it comes down, it will slow down when it approaches the workpiece. When it is pressurized, it will start bending. This speed will be slower!

There is also a situation that the bending force is not enough, which makes it hard to bend! It is necessary to find the reason from the material length, the thickness of the workpiece and the pressure of the machine itself!
