straightening warped aluminum stock | |
I've been buying surplus T6061 rectangular bar and plate lately for my CNC project, and it seems that more often than not, the rectangular bar stock, which all seems extruded, is warped with up to a few millimeters of deflection per foot. The plate stock usually seems to be in good shape though.
Is this typical? I'm guessing the warpage is caused by shear cutting or rough handling.
Is there any way to straighten the stuff to reasonable flatness or do I just need to buy some more material in better shape? |
