The current requirements in the metal sheet folding insist more and more in a higher accuracy in bending, there fore it is indispensable that the angle of the fold is constant along the entire length of the metal sheet.
To achieve this constant, the penetration of the punch into the die has to be equal throughout all the length of the machone, but due to the efforts made in the foldiing operation, the top and the bottom of the press brake undergo a slight bend, causing irregularity on the penetration of the punch into the die.
It is at that point where it is important to consider the installation of an Automatic Compensation Table METALMAQ.
