45-degree Lock Miter Joint - 1

This lock miter joint moulding 45-degree - 1 is designed to mill a locking miter joint on two separate pieces of lumber at 3/4" thickness. The professional cad dxf file contains two high precision template designs to create cutters for this functional detail, one half of the joint is milled on the top or bottom horizontal cutter head, the other on a left or right vertical cutter head on an industrial moulder. Our high precision templates and knives include the required draft angles to maintain the ability to sharpen the blades properly without modifying the detail, while simultaneously prolonging the milling time between sharpening.

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 grinding cutters.

Caution; the cutters will come within .020" of the moulder bed plates when milling this detail. We recommend a wooden, phenolic or plastic sacrificial bed plate be used for these types of milling operations. For knife quoting purposes use the calculator below, we have added only the important measurements, just determine the cutters you need. 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 moulder to help operators save time and increase accuracy during machine setup.

Width = 8.625" / Depth of Cut = .760" (top knives).

Thickness = .750" / Depth of Cut = .812" (left cutters).
