EDM electrode cov ntaub ntawv Muaj ntau yam kev xaiv
EDM electrode cov ntaub ntawv yuav tsum muaj cov khoom uas yooj yim tso cai thiab tseem tiv taus qhov yaig uas cov txheej txheem EDM txhawb thiab txhawb nqa hauv cov hlau nws tshuab. Alloys muaj cov khoom uas muab cov txiaj ntsig sib txawv raws li qhov xav tau ntawm daim ntawv thov.
tooj dagyog ib qho alloy ntawm tooj liab thiab zinc. Cov khoom siv tooj dag yog siv los ua EDM hlau thiab me me tubular electrodes. Brass tsis tiv taus hnav zoo li tooj liab lossis tungsten, tab sis nws yooj yim dua rau tshuab thiab tuaj yeem tuag-cam khwb cia lossis extruded rau cov ntawv tshwj xeeb. EDM hlau tsis tas yuav muab hnav lossis arc yaig tsis kam vim cov xaim tshiab tau noj tsis tu ncua thaum lub sijhawm EDM thaiv cov txheej txheem.
Toojthiab tooj liab alloys muaj EDM hnav zoo dua li tooj dag, tab sis nyuaj rau tshuab dua li tooj dag lossis graphite. Nws kuj tseem kim dua li graphite. Tooj liab yog, txawm li cas los xij, ib qho khoom siv hauv paus vim nws yog cov khoom siv hluav taws xob thiab muaj zog. Nws yog qhov tseem ceeb hauv EDM machining ntawm tungsten carbide, lossis hauv cov ntawv thov uas yuav tsum tau ua kom tiav.
Tooj tungstenCov khoom siv yog cov khoom sib xyaw ntawm tungsten thiab tooj liab. Lawv raug tsim los siv cov txheej txheem hmoov metallurgy. Tooj tungsten yog kim heev piv rau lwm cov ntaub ntawv electrode, tab sis nws yog ib qho tseem ceeb rau kev sib sib zog nqus slots nyob rau hauv cov dej ntws tsis zoo thiab hauv EDM machining ntawm tungsten carbide. Cov khoom siv tooj liab tungsten kuj tseem siv rau hauv kev siv vuam electrodes thiab qee qhov kev siv hluav taws xob hluav taws xob.
Graphitemuab kev ua kom huv ntawm qhov nrawm. Carbon graphite yog ib qho ntawm thawj cov khoom siv txhuam cov qib tsim thiab pom muaj nyob rau hauv ntau lub tshuab qub thiab cov tshuab hluav taws xob. Nws muaj cov qauv amorphous.
Molybdenumyog siv los ua EDM hlau. Nws yog cov xaim ntawm kev xaiv rau kev ua haujlwm me me thiab rau cov ntawv thov uas xav tau tshwj xeeb me me kaum radii. Molybdenum nthuav tawm lub zog tensile siab thiab zoo conductivity, ua rau nws zoo tagnrho qhov chaw me me txoj kab uas hla yuav tsum tau siv rau kev thov.
Nyiaj tungstencov khoom yog tungsten carbide hais dispersed nyob rau hauv ib tug matrix ntawm nyiaj. Silver muaj cov khoom siv hluav taws xob siab thiab tungsten muab kev tiv thaiv zoo heev thiab cov yam ntxwv zoo los tiv thaiv vuam hauv cov ntawv siv hluav taws xob siab. Qhov kev sib xyaw no yog li qhov kev xaiv zoo tshaj plaws rau EDM electrode daim ntaub ntawv uas qhov ua kom zoo tshaj plaws yog qhov tseem ceeb.
Tellurium tooj liabNws yog ib qho tseem ceeb hauv EDM machining daim ntawv thov yuav tsum tau ua kom tiav. Tellurium tooj liab muaj lub tshuab ua haujlwm zoo ib yam li tooj dag thiab zoo dua li tooj liab ntshiab.
