Panel Saw Chips Melamine Inside The Book
Lay several strings of this material with the book of material and let the machine dry cycle the book (not cut). After the dry cycle, remove the plastic gauge and note on the panels the variations in pencil. Rebuild the book and cut the panels in pattern that was dry cycled. Most likely, where you find changes in thickness, you will see your chipping.
From the original questioner:
Believe it or not, that is the only explanation I could think of. What I was thinking is that there are slight hills and valleys that would not allow the book to be compressed, because the chipping wasn't consistent across the panel.
From contributor B:
You make a very good point, but there is another possibility to cause hills and valleys and that is small chips and debris between the sheets as they are loaded on the saw. The following is from a previous post (dated 9/17) also talking about melamine chipping:
Re: Melamine Chipping
Have any of you considered the fact that it might be the melamine itself and not the board or the tools? I have encountered that problem in the past. At a former employer we did our own melamine lamination because of the large volume we used. At one point some genius figured we could save about $1 per sheet by switching brands of melamine. The colors were good and texture was almost identical, but once that stuff got to the machines it sucked. It would chip along the entire route path and even around drill holes larger the 6mm.
What I learned in addition at that time, was that, not only the brand can make a difference, but also the age of the melamine before it is applied to the substrate can make a huge difference. As melamine ages it becomes very brittle. This also becomes a factor after it is laminated too. The longer the sheets lay around in the warehouse or your shop, the more brittle that melamine becomes, thus increasing the chip factor along machined edges.
From contributor A:
Very good point. When I referred to the raw material I was blanketing in the type of laminate or other surface product.
From contributor C:
The first thing I would do is a test to see if the melamine is overcured - a very common problem. Too much heat during the laminating process causes brittle melamine.
