This double-radius edge molding 1/8" - 36 measures 4.000" wide by random thickness, requiring the use of a 4-1/4" wide blank of various thickness lumber for milling on an industrial molder. The knives are capable of milling two 1/8" round-overs on a piece of lumber measuring 4" thickness or width. The acrylic template can be moved over and referenced to either side of the profile knife grinder to manufacture a set of knives for the cutter heads on the molder. This action will enable all four sides of the lumber to get milled simultaneously. Suppose you want to cut the edges of the lumber from the right and left vertical cutter heads to mill random widths; we have other patterns to accomplish this.

Try one of our 125% concentration ultimate CBN (cubic boron nitride) grinding wheels, finish grinding at 3000 rpm with a twenty-degree back clearance angle will create a superior micro edge on all your high-speed steel profile knives. Read this article or watch the videos to help better understand how to align a borazon wheel to axial constant position on a Weinig R960 profile grinder. During the machining process, the knives will be capable of milling some of the finest quality architectural moldings you have ever produced.

For molding knife quoting purposes, click to open the calculator below; we supplied only the important measurements, enter the appropriate dimension in the boxes provided. 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 = 4.000" / Depth of Cut = .281" (top knives) & .281" (bottom cutters).
