Hi guys,
We have a part that we are making that is .032 6061 sheet, and the parts are about 6"x60" with lots of features. Currently we have a pretty bad scrap rate and the cut quality is trash because even down at 100psi or so and a 1.0 nozzle that sheet shakes so bad it's all tip touches and the head dances and it's really like a war going on in there... Has anyone ever cut super thin stuff before? I have tried weighting it down and it still shakes in the middle and sometimes then pulls the material in and puckers and the weights don't let it flatten back out. I can't think of a way to suck it down with vacuum since it's a laser... Maybe clamps on the corners and pulling it tight like a drum? If a guy uses strong magnets do you think that will mess up the head height sensor?
Anyway, it's been a battle... I actually bought a timesaver to sand the backsides to help a little, but that thing is a battle of its own (the tracking doesn't want to work all the time so it smokes a $40 belt basically every time you use it)
Thanks for any ideas or insight!
