Some louver manufacturers mill these types of wood designs with just the top and bottom horizontal cutter heads, saving money on tooling and machine setup costs. Our concern with this machining approach is that you have ninety-degree cuts where the top and bottom cutters intersect on each side edge of the design. This leads to the burning of the knives, which decreases production run times between sharpening. It is also where your eyes will be when the window covering is opened in the horizontal position, exposing all defects in the milling process. Larger cutting circles on the machinery will force you to open bed plates and chip breakers while simultaneously causing snipes (imperfections on the ends of the boards). Trust us, four milling stations are the easier way to mill louver slats, it will cost more money on tooling and more time to set up the machinery, but in the long run, you will have far less machining trouble, your product will be far superior to those mills doing it the less expensive way.
For knife quoting purposes use the calculator below; we have added only the important measurements. A brief detailed explanation of how to use the calculator is located here.
Width = 4.500" / Depth of Cut = .121" (top knives) & .121" (bottom cutters).
Thickness = 1.625" / Depth of Cut = .313" (right blades) & .313" (left cutters).
