Cutting Blade Grooves in Bodies of Inserted Tooth Cutters
Nine of these steel cutter bodies are placed together on an arbor and clamped solidly by a nut at the end. The arbor is then driven into the spiral head spindle and the foot-stock is put in place. To give the proper rake to the front of the blades, the saddle is set so that the cutter does not come directly over the spiral head and foot-stock centres. As the number of grooves cut is 20, indexing can be conveniently accomplished with any index plate.
A side milling cutter 5 inches in diameter and 716'' wide is used, and the grooves are cut to a depth of 78''.
