CHANNEL INLET EDGE DEBURRING FOR GAS DIFFUSER CASES |
摘要 |
A method of deburring channel inlet edges inside a cavity of a gas diffuser case is disclosed. The diffuser case has a plurality of channels each having an inner surface and an inlet edge defining an inlet of the channel. The surfaces of adjacent channels co-operate to provide said inlet edge therebetween. The inlet edges of the channels are provided in an inwardly facing circular array around a central axis of the gas diffuser case. The method comprises: inserting a tool head having at least one nozzle in the cavity of the gas diffuser case; and then ejecting abrasive particles from at least one nozzle towards at least one of the channel inlet edges of the gas diffuser case to at least one of decrease a radius of at least one said edge and improve a smoothness of at least one said surface. |
