Face Milling Surface of Spiral Head Casting

This operation illustrates the use of a face milling cutter with inserted teeth for surfacing a piece of work.

The piece, which is of cast iron, is clamped to a knee to keep it square with the spindle. A strap in front prevents it being pushed away from the cutter, toward which there is a strong tendency.

The cutter is mounted directly on the nose of the spindle, and, in feeding, the work is moved longitudinally from right to left, or so as to force the work down against the table, rather than raise it. Only one cut is taken over the surface.
