| 发明名称 | Superhard cutter element | ||
| 摘要 | A superhard cutter element for machining a workpiece comprising wood, metal, ceramic material or composite material, the superhard cutter comprising a superhard structure (140) having a rake side (110) and a flank side (120), the rake side (110) and the flank side (120) enclosing a wedge angle ω; and a protective layer (170) bonded to the superhard structure (140) at a rake interface (180) on the rake side (110), the protective layer (170) being softer than the material of the superhard structure (140). | ||

| 主权项 | 1. A superhard cutter element for machining a workpiece comprising wood, metal, ceramic material or composite material, the superhard cutter element comprising a superhard structure having a rake side and a flank side, the rake side and the flank side enclosing a wedge angle; and a protective layer bonded to the superhard structure at a rake interface on the rake side, the protective layer being softer than the material of the superhard structure; the wedge angle being at least 20 degrees and at most 75 degrees, a region of the protective layer proximate the cutting edge having a thickness in microns of at least (13.3-0.11ω) and at most the lower of (380-5.0ω) and (126.6-0.11ω), where the wedge angle ω is in the range from 35 degrees to 65 degrees. | ||
