摘要： A single crystal diamond cutting tool capable of increasing the accuracy of a machined surface by improving the discharging property of chips to reduce cutting resistance and enabling an increase in life by less causing the wear-out and micro chipping of a cutting edge when a crystal material and a hard and brittle material are machined by a ultraprecision method. A tip (2) having a round-shaped ridge of the cutting edge is fitted to the tip of the tool. At least the portion of the ridge of the cutting edge acting as the cutting edge (5) is formed with a specified radius since a first conical surface forming a face (3) is intersected with a second conical surface forming a flank (4). The roundness of the ridge of the cutting edge is less than 100 nm in radius, the width of the first conical surface is 1 to 5 μm, and a chip escape surface (6) in a roughly vertical direction to a cutting direction is formed at the portion of the first conical surface on the opposite side of the ridge line of the cutting edge. A crossing part between the first conical surface and the chip escape surface is formed in a round face, and its radius is 0.1 to 1.0 μm. The face of the first conical surface is negative 15 to 50°.

摘要翻译： 本发明提供一种单晶金刚石切削工具，通过提高切屑的排出性能，提高切削加工面的精度，降低切削阻力，并且在晶体材料少的情况下，能够减少切削刃的磨损和微小碎屑， 并且通过超精密方法加工硬而脆的材料。 具有切削刃的圆形脊的尖端（2）被安装到工具的尖端。 由于形成面（3）的第一圆锥面与形成侧面（4）的第二圆锥面相交，因此至少切割边缘的用作切割边缘（5）的部分形成有特定的半径。 切削刃的凸脊的圆度小于100nm，第1圆锥面的宽度为1〜5μm，在切削方向的大致垂直方向上形成切屑逸出面（6） 在切削刃的棱线的相反侧上的第一锥形表面的部分。 第一圆锥面和切屑逸出面之间的交叉部分形成为圆形面，其半径为0.1〜1.0μm。 第一个锥形表面的正面为负15至50°。

摘要： A method for preparing a contact surface of an implantable bone, joint or similar prosthetic component subject to contact or motion includes the steps (10,12,14) of mounting the prosthetic component (16,16') on a turning or cutting machine (24) and cutting the face of the prosthetic component (16,16') with a diamond cutting tool (36B) using computerized control of tool position along a cross direction to machine cut a super finished surface. The diamond cutting tool (36B) has a precise contact point and is shaped with a waviness under about 0.5 micrometers effective to cut a surface profile free of visible tool marks. As cut, the variations of contour (42) and the surface roughness are both under about 0.5 micrometers, and preferably under about 0.2 micrometers or less. Upon implantation, the super finished surface generates wear particles at an asymptotically low or residual level during wear-in which may enhance wear characteristics and reduce local reaction or systemic rejection effects. The component (16,16') is preferably formed by a strong hard polymer, such as UHMWPE, and may be a cup (16'), liner, stem, head, tray (16), insert shell or other wear surface element of an implantable joint assembly.

摘要： A polycrystalline diamond sintered material tool includes: a cemented carbide substrate (17), which is mainly composed of WC and includes Co; and a diamond layer (18) containing a metal catalyst made of Co provided on the cemented carbide substrate (17). The average layer thickness of a Co rich layer (19) formed in an interface between the cemented carbide substrate (17) and the diamond layer (18) is 30 µm or less. Preferably, a value of C MAX /C DIA is 2 or less when C DIA is defined as an average content of Co included in the diamond layer (18) and C MAX is defined as a peak value of a Co content in the Co rich layer (19). More preferably, a value of D/Do is less than 2 when D is defined as average grain size of WC particles in a region from the interface between the cemented carbide substrate (17) and the diamond layer (18) to 50 µm toward an inside of the cemented carbide substrate (17); and Do is defined as an average grain size of WC particles in the inside of the cemented carbide substrate (17).
