I am getting ready to cut some 1" polyethylene foam on this machine. I wanted to record my progress on here since I can’t seem to find much information on cutting this material.
The purpose of this project is to solve the packaging problem in our assembly department. Currently, we bag everything in foam and plastic bags, then use cardboard to keep the layers of parts rigid. Of course that goes in to a cardboard box.
For softer material like copper, we box each item individually. So, our solution is to use PE foam to create a rigid pattern of channels for the parts to go into.
After writing the above statement, I found the cutting calculator and saw that Wazer does not recommend cutting 1" material. Well, I thought that was pretty hypocritical of the “cut any material” statement, so I gave it a try.
My test cut was 3.5 second pierce at 60 IPM. This cut ALMOST all the way thru. It was so close, that bottom layer was a lot like a perforated cut, so I was just able to tear the dropouts off. The solution is definitely 4s pierce at 50 ipm. I’ll update results once we get the material in.
*edit: this was without abrasive.
