Tooling for Laminated Flooring
For clarification, how much is a lot of flooring? Running flooring full time justifies the diamond easier. Running 15,000 square feet of flooring a month may not justify the diamond as easy.
From contributor R:
I am involved with small flooring operation that focuses on the very product that you are discussing. Although shear will help to some degree, experience has led me to the following:
1) Dull inserts cause problems. Sounds ridiculously simple, but after you change your inserts, there will be a noticeable change in quality and when they are past their life, they show bad results very quickly.
2) Carbide grade is everything. If you are getting run of the mill inserts with a generic carbide grade you will get run of the mill results. Ask your tooling provider about the micro grain carbides (which most inserts are these days, but there are still some less expensive ones out there) and make sure you are getting a good micro grain product. There is a difference in price, but that comes with quality.
3) Pay very close attention to how you are ripping your base plywood. If you do what is essentially a cross cut and then laminate that to a linear top layer, the surface of the plywood is a cross grain cut as opposed the linear grain cut for your wear layer. We had some fellows that tried to precut to the length of the wear layer and did some cross cutting on the plywood. Bad, bad things happened to the quality of the product and several hundred feet were lost.
4) I don’t know how you are gluing, but we are using bladder presses with some additional tricks that ensures even pressure across the width and length of the board. We have had de-lamination problems, which in turn caused edge quality issues, but those were easy to fix.
