SURFACE TREATING METHOD BY ELECTRIC DISCHARGE, AND DRESSING METHOD |
摘要 |
<p>To enable surface treatment of the inside of a part or the like and also simplify grinding work by equipment and a procedure that are simple in comparison with convention. A first semi-sintered electrode 31 that is formed in a tapered shape whose distal end portion becomes smaller in diameter toward the distal end portion is attached to an electrode supporting tube 26, is configured to be rotatable by a motor 27, is positioned near a seat portion 8 of a nozzle body 1, and generates electrical discharge by surface modifying electrical discharge machining method between the seat portion 8 and the first semi-sintered electrode 31, whereby a coating that is formed as a result of the material that forms the first semi-sintered electrode 31 being moved and deposited can be formed on the seat portion 8 and grinding treatment of the inside of the nozzle body 1 matching the outer diameter of a nozzle needle 2 as has conventionally been the case can be rendered unnecessary.</p> |
