45 Degree Back Bevel Cutter

45 Degree Back Bevel Cutter

These 45 degree back bevel cutters are designed to mill a forty-five-degree chamfer on the backside of a crown, cove, or bed moulding when milled sprung, laying horizontally flat from the right or left vertical moulder spindle. These knives create half the determining factor of the final height and projection of these types of mouldings when installed. The other half of the equation for back cuts on these styles of mouldings will be a degree that combined equals ninety or slightly more, depending on the manufacturer's tolerances.

On this moulding cutter layout the maximum depth of cut is .781", the maximum height of cut is fixed at .781". Every sprung moulding, we design have height of cut numbers near the degree bevel on the layout papers we provide, that number must be smaller than the height number, in this equation .781" for this knife to be able to cut the entire back bevel while milling, if not please select a larger size height of the same degree. We purposely layout all our sprung mouldings with forty-five-degree back bevels and under to be milled on the right vertical spindle, and all forty-five-degree back bevels and higher to be milled on the left vertical moulder spindle. This custom design practice will save thousands of dollars in manufacturing cost over the years, as well as moulder setup time.

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