Abstract: Изобретение относится к электроэрозионной обработке деталей в машиностроении и может быть использовано, в частности, для выполнения сопловых отверстий в распылителях форсунок двигателей внутреннего сгорания. Способ включает прошивку отверстия подвижным электродом-инструментом в режиме электроэрозионной обработки с герметизацией отверстий. Герметизацию прошитых ранее отверстий осуществляют с помощью вытеснителя, который устанавливают в корпус обрабатываемого распылителя с малым зазором по цилиндрической прецизионной части корпуса распылителя и с герметичным прилеганием вытеснителя по запорному конусу корпуса распылителя. Электрод-инструмент в процессе прошивки перемещают до внедрения в тело вытеснителя на малую контролируемую величину, причем для прошивки второго и последующих сопловых отверстий корпус распылителя поворачивают вокруг вытеснителя в угловое положение так, что оси полости, образованной в теле вытеснителя при внедрении в него электрода-инструмента, и электрода-инструмента постоянно совпадают. Эвакуацию продуктов эрозии осуществляют по кольцевому каналу, образованному стенками обрабатываемого отверстия и электродом-инструментом. Изобретение обеспечивает гидроединообразие прошитых сопловых отверстий и исключает внедрение электрода-инструмента в противоположную стенку корпуса распылителя. 1 ил.
