alled EDM 電火花加工是利用浸在工作液中的兩極間脈沖放電時(shí)產(chǎn)生的電蝕作用蝕除導(dǎo)電材料的特種加工方法,又稱放電加工或電蝕加工,英文簡(jiǎn)稱 EDM 2 The principle of the EDM ? In insulating working fluid, generating a pulse of the spark discharge between the tool and the workpiece,producing instantaneous high temperature and the melting off the surface of the workpiece, to achieve the purpose of the metal surface is processed. ? 在絕緣工作液中,工具與工件間產(chǎn)生脈沖性火花放電,產(chǎn)生局部瞬時(shí)高溫,使工件熔化而拋離工件表面,達(dá)到金屬表面被加工的目的。 11 電火花加工原理圖 ?
