A cutter assembly (10, 140, 120) incorporating a flexible disk (20, 45, 140) which acts as the cutting element, mounted between a cutter back (15, 43, 130) and a disk retainer (30, 150, 137). The cutter back includes a conical mounting face, and the disk retainer has a complementary mounting surface, so that the disk is clamped between these surfaces and deflected to create a negative rake angle. The disk is formed with profiles which protrude beyond the cutter back and retainer, and it has a constant cross-section throughout its width. When the cutting edges become dull, the disk may be inverted and reused due to its untapered profile; after such reuse, the disk is discarded. The cutter disk is easily fabricated in groups, and enjoys economical, high performance operation, |
