摘要： A cutting tool for cutting a lead-free copper-based bearing alloy containing 75 to 95% by mass Copper(Cu):, 1 to 15% by mass Bismuth(Bi), and 1 to 10% by mass hard particles comprising metal phosphide, boride, or carbide. The Cutting tool includes a rake surface, a clearance surface, and a cutting edge formed on a line of intersection between the rake surface and the clearance surface. A tip end site including the cutting edge comprises a diamond tip, and the diamond tip comprises a sintered body formed by sintering diamond particles having an average particle diameter (D50) between 0.2 μm and 1.6 μm. The cross section of the cutting edge preferably has a curved surface shape with a radius of curvature between 10 μm and 50 μm.

摘要： A front cover affixed to the pump impeller of a torque converter, provided with a flat annular flat annular surface to be engaged with the clutch disk of a direct-coupling clutch formed within the torque converter.The flat annular surface is formed in a flat and annular surface having a hard and compact metallographic structure by rolling a rolling tool made of a extremely hard material on the flat annular surface under a pressure and by thus causing plastic deformation of the flat annular surface. An intermediate part of an arcuate section of a small radius is formed between the periphery of said flat annular surface and a connecting part adjacent to the flat annular surface.
摘要翻译：固定在液力变矩器的泵叶轮上的前盖，其设置有与形成在变矩器内的直接联接离合器的离合器盘接合的平坦的环形平坦的环形表面。平坦的环形表面通过在平坦的环形表面上在压力下滚动由非常硬的材料制成的滚动工具并由此引起平坦的环形表面的塑性变形而形成具有硬且致密的金相组织的平坦且环形的表面。在所述平坦环形表面的周边和与所述平坦环形表面相邻的连接部分之间形成小半径的弧形部分的中间部分。
