1. Ionization ntawm polar nruab nrab, tawg
Lub ionization thiab kev tawg ntawm qhov nruab nrab nruab nrab ntawm qhov nruab nrab tsim cov kab hluav taws xob tawm, cov cuab yeej electrode thiab cov khoom siv hluav taws xob tau maj mam txav mus, thiab lub zog hluav taws xob ntawm qhov nruab nrab ntawm qhov nruab nrab nce. Vim tias qhov chaw microscopic ntawm ob lub electrodes tsis sib xws. Yog li ntawd, qhov hluav taws xob yog qhov loj tshaj plaws ntawm A thiab B qhov kev ncua deb ntawm ob tug ncej yog qhov ze tshaj plaws. Muaj cov kua nruab nrab nruab nrab ntawm cov cuab yeej electrode thiab lub workpiece electrode. Cov kua nruab nrab inevitably muaj impurities thiab dawb electrons. Nyob rau hauv qhov kev txiav txim ntawm lub zog hluav taws xob, lawv tsim cov khoom tsis zoo thiab cov khoom zoo. Qhov ntau dua lub zog hluav taws xob, Cov khoom siv hluav taws xob ntau dua, nws thiaj li ua rau ionization thiab tawg ntawm cov kua nruab nrab, tsim cov kab tawm.
2. Tom qab melting thiab vaporization ntawm cov khoom siv electrode, lub thermal expansion kua nruab nrab yog ionized thiab tawg, thiab tom qab lub tso tawm channel yog tsim, lub negatively charged hais nyob rau hauv lub channel khiav mus rau lub zoo electrode hais thiab sib tsoo. Ib tug loj npaum li cas ntawm tshav kub yog generated, thiaj li hais tias cov channel instant pupa yog them rau ib tug heev kub. Qhov kub ntawm cov channel ua ntej vaporizes cov dej ua haujlwm, thiab tom qab ntawd qhov kub thiab txias kis mus rau ib puag ncig, kom cov khoom siv hlau nkhaus ntawm ob qhov chaw electrode pib yaj kom txog thaum nws boils thiab vaporizes. Lub ntim ntawm vaporized ua hauj lwm kua thiab hlau vapor nce instantaneously, tsim cov yam ntxwv ntawm kev tawg. Yog li ntawd, thaum soj ntsuam lub machining ntawm Cnc tshuab cuab yeej, nws yuav pom tau hais tias lub workpiece thiab lub cuab tam electrode muaj pa taws thiab ib tug me ntsis tawg suab yog hnov.
3. pov tseg cov khoom siv electrode
Lub txim tshwm sim generated ntawm qhov zoo thiab tsis zoo electrodes ua rau cov paug tawm channel tsim high voltage. Lub siab nyob rau hauv nruab nrab ntawm lub channel yog siab tshaj. Tom qab cov dej ua haujlwm thiab cov hlau yog vaporized, lawv txuas ntxiv mus rau sab nraud, tsim qhov sib txawv ntawm qhov sib txawv ntawm sab hauv thiab sab nraud. Cov kua hlau molten thiab vapor ntawm lub siab siab raug thawb tawm thiab pov tawm ntawm cov kab tawm, thiab feem ntau ntawm lawv tau muab pov rau hauv cov kua dej ua haujlwm. Kev saib ze dua ntawm EDM tuaj yeem pom cov txiv kab ntxwv-liab nplaim taws ya ncig. Qhov no yog cov hlau kub kub thiab cov khib nyiab pov tseg.
4. Deionization ntawm polar media
Yog tias cov khoom siv corrosion galvanic tsim thaum lub sij hawm tso tawm ntawm Cnc tshuab cuab yeej tsis raug tshem tawm thiab diffused nyob rau hauv lub sij hawm, lub tshav kub generated yuav tsis kis nyob rau hauv lub sij hawm. Lub hauv paus overheating ntawm nruab nrab yuav ua rau lub zos overheated ua hauj lwm kua rau decompose thiab tsim carbon nyob rau hauv high kub, ua rau kev ua tsis tau. Thiab hlawv tawm cov electrode, yog li txhawm rau txhawm rau ua kom lub cev ua haujlwm ntawm Cnc tshuab cuab yeej, yuav tsum muaj sijhawm txaus ntawm ob qhov kev tso tawm kom tso cai rau cov khoom siv galvanic corrosion kom tag nrho tawm, rov qab cov rwb thaiv tsev ntawm cov paug tawm, thiab deionize. cov dej ua haujlwm nruab nrab.
