Machining Bead Board Profiles
If producing bead board is part of your product offering, there are several options to achieve this profile. The preferred option with grooving capability is using a profile insert or PCD (polycrystalline diamond) cutter head. It is the most efficient and cost effective solution, allowing the bead board profile to be cut in a single pass, without tear-out. If you’re using this on a table saw for instance, the cutter body would be produced of light weight aluminum to keep the weight of the tool to a minimum reducing wear on the machine.
Some bead board profiles can also be made as a custom saw blade, which incorporates the bead board profile and can be run on a table saw. (see illustration below).
Another option, if only smaller quantities of a conventional bead board (profile as shown below) are produced, requires either a 5-axis CNC machine or a variable angle aggregate head to accomplish the task. This method is more time consuming and only advisable for small runs because it requires 4 passes to complete the profile. It also requires either the tool to be on a spindle tilt, or the material to be on an angle while being machined. The tool on the left is a V-Groove tool used to complete the two outside grooves in two passes, while the tool on the right completes the inside “bead” profile in two passes. Whether using a profile cutter head or router tools, both options will provide an excellent, paintable finish.
Finally, of course it is easy to produce a modified bead board profile with any router that can be machined in just two passes . However, it requires the outside edge of the bead profile to have a radius as well. (i.e. another radius, mirroring the center radius will make up the outside edge of the bead and the angle will be eliminated.)
