55 Degree Back Bevel Cutter

These 55-degree back bevel cutters are designed for milling a fifty-five-degree chamfer on the left cutterhead on the backside of a piece of crown, cove, or bed moulding when milled sprung (laying horizontally flat). When installed, these knives create only half the determining factor of the final height and projection of the crown, cove, or bed moulding. The other half of the equation for back cuts on these types of designs will be a degree that combined equals ninety or slightly more, depending on the manufacturer's tolerances.

On this cutter layout, the maximum depth of cut is 1.062", and the maximum height of cut is fixed at .744". Every sprung moulding design has a height number near the degree bevel on the layout papers we supply. That number must be smaller than the height number, in this case, .744" for this knife to be able to cut the entire back bevel while milling; if not, please select a larger size height bevel of the same degree; we have a few options available for your review. We uniquely layout all our sprung moulding designs with forty-five-degree back bevels and under to be milled on the right cutterhead and all forty-five-degree back bevels and higher to be milled on the left cutter head. This custom design practice will save thousands of dollars in manufacturing costs and machine setup time over the years.

Please read our commentary about axial constant position for crown mould bevels, the article will help you dial this profile in axially on the first try when milling provided the machine is axially calibrated.
