Laser Cutting s/s with plastic film on bottom (N2)

[laserguy04]

Hi, our laser is an Amada lc-667 II and moves the sheet rather than the cutting head, we have been trying to put the plastic side of the sheet on the bottom to protect it from marking from the balls but we keep getting a burr on the bottom edge. My question is has anyone else tried this? and did you find a solution to getting rid of the burr?

Cheers,

Jamie.

We had a similar problem although ours was related to reducing handling damage rather than damage caused by moving the sheet over the table. We spent a lot of time on this and discussed it with our machine tool supplier. Sadly we did not come up with a satisfactory solution, although we did have some success of thin (0.7mm) stainless sheet and aluminium (0.9mm) it wasn't repeatable.

I our case the majority of these parts were routed back through our punch.
