Press brake tools are stressed every day in two simple, yet intense, ways:
1) Tools are compressed during each stroke of the press brake.
2) Tools are also “scratched” by the sheet metal we are bending every time the tools are used.
Maintaining the exact height of a tool is vital to the process of bending.
because to every 0.05mm of stroke, the sheet metal closes 2°
To put it another way…
if the height of the tool varies, or worst, if it varies only in certain parts of the tool… well, our part will never come out properly.
If tools change height due to normal use, no crowning system can help it…. we will have either a”banana effect” or a “snake effect” on our part.
