Hello,

We recently acquired a Durma folding machine. We asked for the Excel table of the V-folds, but the sales representative's answer was: "These are the same as AMADA's."

Do any of you have a table that could serve as a base, to complete or to evolve with our tools?

We work exclusively with stainless steel, with thicknesses of up to 6 mm and maximum lengths of 3 m.
Thanks in advance

Attached is the table of loss at the fold given by the manufacturer of our new folding machine (table also identical to amada

Each manufacturer has his own paintings, it is up to him to provide them, otherwise no work is possible

Thank you Bob for the feedback. However, if we just have to wait for the supplier to get back to us, in six months the matter will still not be settled.

When a 40 A circuit breaker is recommended for a bending machine and, after installation, the reading of the electrical diagram clearly indicates a protection of 63 A, it seems to me that the expected level of requirement is not met by this supplier.

@sbadenis , question did you manage to transcribe in the solidworks tables?
I don't have the impression that it's good management in 2020. Does the more recent versions bring a plus in sheet metal?

In the attached link at the end of the topic you will find the tables used in our SW for our Amada folding machines. On the other hand, these tables were created by entering them in the folding machine and transferred them to the table. (and verification via some samples 15-20 years ago!)
