How to Grind Staggered Tooth Milling Cutters
SINCE the heavy duty spiral milling cutter of the alternate or staggered tooth type is coming into greater use, a few suggestions about the simplest way of resharpening it may be helpful. The two photographic illustrations show one of the cutters on the grinding machine; the arrows indicate the direction in which the cutter should be moved across the face of the wheel. The diagram explains the kind of tooth rest used. The angles A should be equal to the helix angle of the cutter. The wheel B should be dressed very narrow, not exceeding y in. at the cutting edge. The apex of the rest (C) should be exactly in the center line of the wheel. —H. B. SCHOTT.
