American 7260 crawler crane

[D8R]

I have used laser as much as possible (unless I couldn´t make drawings) on my D8r and I think it´s very accurate. i do a lot of tabs and holes to fix parts together and normaly I only have to use moderat forces to get pieces bond together (before welding or brazing). My latest used supplier has a special gas when cutting with laser so faces will not be burnt.
With an edm machine it should be possible to make differences in hight of the material, not only cut through it I think.

Hi Dan

Don't get me wrong laser cutting is indeed very accurate
In fact it's probably more accurate then needed for most of our work.
I think i would prefer a laser cutting for my parts.
like i said i am lucky enough to have access to wire edm so i use it.
But you i can tell you we reach accuracies of 0.003 mm in holes with wire edm.
Thats not with one simple cut but but wit 5 or 6 cuts.
The last few cuts are done with a very low amp just to polish and take off the last few microns.
OK thats far over specified for our parts but it can be done with wire edm.
