Abstract
A high speed planer head. A threaded member having a frustoconical portion wedges against a knife, to clamp a knife to a hub for rotating the knife about an axis of revolution. The knife has a front and back side, two cutting edges and mirror image symmetry about a mirror plane passing through the knife. To cut both a planar face and two opposed, radiused corners, the cutting edges include respective linear face-cutting portions disposed between two concave, arcuate corner-cutting portions.
Claims28
A cutting apparatus, comprising:
- a knife having a front and back side, two cutting edges and mirror image symmetry about a mirror plane passing through said knife;
- a hub for rotation about an axis of revolution, said front side facing the direction of rotation, said hub having a pocket for receiving said back side of said knife against a supporting wall of said pocket, and a threaded hole;
- and
- a threaded member having a frustoconical ramping portion for producing a wedging force against said knife when said threaded member is threaded into said hole.
A knife for a cutting apparatus adapted to rotate the knife about an axis of revolution, the knife having a front and back side, the front side for facing in the direction of rotation, two cutting edges and mirror image symmetry about a mirror plane passing through said knife, wherein said cutting edges include respective linear face-cutting portions disposed between two concave, arcuate corner-cutting portions.
