Crown Moulding 8-1/16" - 1

This concave crown molding 8-1/16" - 1 measures 8.046" width by 1.250" thickness necessitating the use of six quarter lumber for machining on an industrial-grade molder. The graceful terminating profile contains a 7/8" vertical line segment on the top left. The line joins to an eight-inch radius concave semicircular arc in the center with a 9/32" broad horizontal fillet and a 3/8" by 3/8" perpendicular lines on the bottom right corner of the design. The fixed spring angles are set at thirty-eight and fifty-two degrees; these particular back bevels keep the face side of the profile parallel to the wall and ceiling when installed; they also lock in the positioned height at 6-1/2" tall with a projection of 4-3/4" across the top.

Our purple colored ceramic blend grinding wheel hogging at 2000 rpm with a twenty-five-degree back clearance angle will rough grind a set of high-speed steel cutters in a minimal amount of time. Review our article on the importance of having the profile grinder level. This commentary will insure prolonged use of your machinery while maintaining consistent perfection when manufacturing the cutters.

A brief detailed explanation on how to use the calculator is located here. If you would like some assistance with the dimensions, print a copy of our fraction - decimal - millimeter chart, place it on the molder or around the shop to help machine operators save time and increase accuracy during setup procedures.

Width = 8.062" / Depth of Cut = .713" (top knives).

Thickness = 1.250" / Depth of Cut = .563" (right blades) & 1.254" (left cutters).
