Description: |
| "This invention relates in general to milling machines and has more particular reference to those of the knee-type in which the frame is shaped to provide an overhanging or projecting head for supporting a vertical cutter-holding spindle in addition to the customary horizontal spindle journaled in the upright portion or frame proper of a milling machine. The primary object of my invention is to provide a milling machine in which an angular face or a sharp corner may be milled in one operation by a pair of face milling cutters each of which shall mill a surface of a width substantially equal to its face diameter." |
