Fig. 3217.
[Figs. 3217] to [3220] represent examples of the shapes of cutters for use on edge moulding or friezing machines. [Fig. 3217] represents a cutter for bevelling the edge of the work, the cutting edges being at a, b, or at c, d, according to the direction in which the cutter is revolved.
Fig. 3218.
[Fig. 3218] represents an ogee cutter, in position on the cutter spindle. As these cutters are made solid and accurately turned in the lathe, they are balanced so long as the cutting edges are kept diametrally opposite. The front faces only being ground to sharpen the cutting edges, the cutter always produces work of the same shape.
