on a sheet cut and folded of thickness 6 mm it is advisable to make the holes m8 at the last or already in phase of cutting a pre-hole diameter 6.5 (or 6)
thanks for availability
hi, I usually do all possible pre-holes or at most dots if the thickness makes it impossible a proper hole.
Of course for s235jr or aluminum sheet, for other materials I have no experience.
attention that sometimes the [Bleep] plates are too close to where the laser or plasma passes and therefore for holes of small diameter (up to m8), very difficult mapping.
I hope I have been helpful to you :d
Yes thanks for the answer, until a few months ago I worked in heavy mechanics and on the plates at the most I made holes passers not pre-coating for mapping, only in the sides of a type 3 pre-columin for self-tapping screw not by mapping.
