Hluav taws xob tawm machining (EDM), tseem hu ua hluav taws xob tawm machining (EDM), tsis tu ncua ua rau cov pa taws tawm ntawm lub cuab yeej thiab cov khoom ua haujlwm thaum lub sijhawm ua haujlwm. Nws qhov zoo dua yog tias nws tuaj yeem ua cov ntaub ntawv nyuaj-rau-txiav, cov ntaub ntawv nyuaj xws li cemented carbide, thiab ntau yam High speed steel thiab txawm pob zeb diamond thiab cubic boron nitride. Tungsten tooj liab electrodes yog dav siv nyob rau hauv lub teb ntawm EDM vim lawv zoo lub cev thiab tshuaj zog.
Tungsten tooj liab electrode yog cov khoom siv alloy nrog tungsten thiab tooj liab ua nws cov khoom tseem ceeb. Nws muaj cov yam ntxwv ntawm lub zog siab, ceev cua sov dissipation, zoo hluav taws xob conductivity, zoo thermal conductivity, zoo heev kub kuj thiab arc ablation kuj, thiab yog dav siv. Hauv kev lag luam xws li hluav taws xob tawm machining, tsis kam vuam, thiab electrochemical machining.
Hauv EDM, tungsten tooj liab electrodes tuaj yeem txhim kho kev ua haujlwm tau zoo, txo cov electrode poob, txhim kho qhov tseeb ntawm pwm thiab cov khoom, thiab tuaj yeem ua tiav cov machining ntxhib thiab ua tiav ntawm cov khoom hauv ib qho mus. Tsis tas li ntawd, vim hais tias cov khoom siv tooj liab tungsten muaj lub zog siab thiab ntom ntom, nws tuaj yeem tiv taus ntau dua cov neeg kho tshuab siab thiab kub, yog li tsis txhob ua yuam kev los ntawm electrode deformation.
Txhawm rau kom muaj kev ruaj ntseg thaum lub sij hawm EDM thiab txhim kho kev siv cov khoom siv hluav taws xob, cov khoom siv tooj liab thiab tungsten yuav tsum muaj cov khoom zoo sib xws thiab ceev. Tsis tas li ntawd, EDM electrodes yuav tsum tau muab cov tooj liab tungsten electrodes nrog cov duab sib xws thiab qhov tseeb raws li qhov yuav tsum tau ua ntawm cov cuab yeej, pwm lossis cov khoom ua tiav.
