42 Degree Back Bevel Cutter - 1

42 Degree Back Bevel Cutter - 1

42 Degree Back Bevel Cutter - 1

This forty-two-degree - 1 back bevel cutter is designed to mill the back sides of a piece of bed mold, cove or crown molding during the machining process. These knives create half the determining factor of the final height and projection of these types of moldings when installed. The other half of the equation for back cuts on these profiles 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 .732", the maximum height of cut is .813". Every sprung molding we design have a height of cut numbers near the degree angle on the layout papers we provide. That number must be smaller than the height number; in this equation, .813" is the maximum 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 patterns with forty-five-degree back bevels and under to be milled on the right cutter head, and all forty-five-degree back bevels and higher to be milled on the left vertical cutter head. This custom design practice will save thousands of dollars in manufacturing costs over the years and machine 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.

For knife quoting purposes, click to open the calculator below; we have added only the important measurements; please enter the appropriate dimension in the boxes provided. A brief detailed explanation on how to use the calculator is located here. Need some assistance with the dimensions? Print a copy of our fraction - decimal - millimeter chart, place it on the molder to help operators save time and increase accuracy during machine setup.

Thickness = 1.625" / Depth of Cut = .732" (right blades).
