    • An electrochemical grinding tool and method capable of rounding sharp edges that may be prone to cracking, for example, edge regions of cooling slots within dovetail slots of turbine wheels. The electrochemical grinding tool includes a drilling assembly, a conductive bit, and a motor for rotating the conductive bit about an axis thereof. The conductive bit of the electrochemical grinding tool is inserted into a first slot, an electrolyte solution is applied between the conductive bit of the electrochemical grinding tool and a second slot that intersects the first slot, an electrical potential is applied to the conductive bit and the turbine wheel to create a potential gradient between the conductive bit and the edge of the second slot, and material is removed from the edge of the second slot by displacing the conductive bit about and along the edge.
    • 一种电化学磨削工具和方法,其能够使倾斜的尖锐边缘变圆,例如涡轮机叶轮的燕尾槽内的冷却槽的边缘区域。 电化学研磨工具包括钻孔组件,导电钻头和用于使导电钻头围绕其轴线旋转的马达。 电化学研磨工具的导电钻头被插入第一槽中,电解质溶液被施加在电化学研磨工具的导电钻头和与第一槽相交的第二槽之间,电位被施加到导电钻头和 涡轮机叶轮以在导电钻头和第二槽的边缘之间产生电位梯度,并且通过使导电钻头沿着边缘移动并沿着边缘将材料从第二槽的边缘移除。
