| 发明名称 | Method of machining surfaces of rotor disc and grinding machine therefor | ||
| 摘要 | A method of manufacturing turned surfaces of a rotor disc of a gas turbine engine, including rotating the rotor disc about its central axis, rotating an abrasive grinding wheel having an outer grinding surface with a hardness greater than that of a material of the rotor disc, contacting the rotating wheel with at least one annular surface of the rotating disc, and sliding the rotating wheel along a curved cross-sectional profile of the at least one annular surface of the rotating disc. | ||

| 主权项 | 1. A method of manufacturing turned surfaces of a rotor disc of a gas turbine engine, the method comprising: rotating the rotor disc about a central axis thereof; rotating an abrasive grinding wheel, the abrasive grinding wheel having an outer grinding surface with a hardness greater than that of a material of the rotor disc; contacting the rotating wheel with at least one annular surface of the rotating disc; and while contacting the rotating wheel with the at least one annular surface of the rotating disc, sliding the rotating wheel along a curved cross-sectional profile of the at least one annular surface of the rotating disc. | ||
