PURPOSE:To easily realize a highly accurate metal machining for metallic work pieces such as leads for electronic parts, sheet metal of vehicle body, and others. CONSTITUTION:A high-pressure air passage 3 and a particle group flow passage 4 crossing therewith are made in a nozzle body 8, so that a jet stream 7 of high-speed air including particles 5 can be formed through an ejector 6 of the body 8. Therefore, desired machining can be carried out by spraying this jet stream 7 over work pieces such as leads, sheet metals for vehicle body, or the like. |
