Bystronic 4020 (20mm Mild/Hardox Cutting problems)

[jasonmurphy70]

Hello new to this forum,

Hoping someone could help, have started working with the bystronic bystar 4020 at work, All the parameters have been messed about with a lot by previous users so am trying to make a new set to cut from, have got most thicknesses cutting mint even 15mm.

Just when i try cutting 20mm mild or 20mm hardox i am having a lot of problems, the cut looks good on the top half but really rough towards the bottom, some weld and am having to pierce it twice as if i try a first time pierce it shoots back.

Does anybody use the same machine and get good results? if so could i get the parameters that you use for this at they should be close to what i need. The fustration of working it all out is getting to me.

Thanks for your help in advance

Jason (stressed)
