Cov yam ntxwv zoo ntawm graphite cov khoom siv electrode cov khoom

1, cnc machining muaj kev nrawm nrawm nrawm, muaj peev xwm txiav, thiab kho tau yooj yim

Lub cnc machining ceev ntawm graphite yog nrawm, 4-5 zaug uas cov tooj hluav taws xob tooj liab. Lub precision machining ceev yog tshwj xeeb tshaj yog, thiab nws lub zog yog ntau heev. Rau ultra-siab (40-100mm) thiab ultra-nyias (0.2-0.8mm) graphite electrodes, lawv tsis yooj yim deformed thaum ua. Ntxiv mus, feem ntau, cov khoom yuav tsum muaj cov nyhuv zoo, uas xav tau thaum ua cov electrodes, nws yog ib qho tsim nyog los ua kom yooj yim graphite hluav taws xob ntau li ntau tau. Txawm li cas los xij, muaj ntau yam zais cov fab hauv kev tsim cov graphite electrodes. Vim yog qhov yooj yim rau trim xwm ntawm graphite, qhov teeb meem no tau daws tau yooj yim thiab cov xov tooj hluav taws xob tau zoo heev, uas cov hluav taws xob liab tau ua tiav tsis tau.

2, tsis yog nws lub tsho, tab sis nws kuj muaj tus nqi tsawg

Nyob rau hauv kev tsim cov nqi tsim ntawm ib pawg ntawm cov pwm, lub tshuab CNCPivMus rau tooj liab, graphite hluav taws xob muaj machining ceev thiab EDM ceev uas yog 4-5 zaug nrawm dua tooj liab. Nyob rau tib lub sijhawm, tus yam ntxwv ntawm kev hnav me me thiab kev tsim cov graphite graphite hluav taws xob tuaj yeem txo cov hluav taws xob, uas nyeg txo cov consumables thiab machining lub sijhawm ntawm electrodes. Tag nrho cov no tuaj yeem txo qis cov nqi tsim cov pwm.

3, Ceev ceev edm sib sau, tsis muaj zog nthuav dav, thiab poob qis

Vim tias qhov zoo dua ntawm graphite hluav taws xob piv rau tooj liab, lawv txoj kev tshem tawm yog 4-5 zaug nrawm dua li tooj liab. Thiab nws tuaj yeem tiv thaiv ib qho loj tam sim no thaum tso tawm, uas yog qhov zoo dua rau cov hluav taws xob hluav taws xob rho tawm Machining. Lub caij no, nyob rau tib lub ntim, qhov hnyav ntawm graphite electrodes yog 1/5 zaug ntawm tooj liab, zoo heev txo lub nra ntawm edm. Nws muaj qhov zoo heev hauv kev tsim cov hluav taws xob loj thiab cov hluav taws xob ua ke. Lub sublimation kub ntawm graphite yog 4200 ℃, uas yog 4-5 zaug uas tooj liab (lub sublimity kub ntawm tooj liab yog 1100 ℃). Thaum muaj kub kub, kev deformation yog tsawg (1/3 txog 1/5 ntawm tooj liab nyob rau hauv tib lub hluav taws xob tej yam kev mob) thiab tsis mos muag. Nws tuaj yeem ua tau zoo thiab hloov pauv hloov hluav taws xob rau lub workpiece nrog kev noj tsawg. Vim tias tau nce lub zog ntawm graphite electrodes ntawm qhov kub, lawv tuaj yeem txo qis kev poob (graphite poob yog 1/4 tooj liab), ua kom tiav cov khoom lag luam ua tiav.

Nyob rau hauv xyoo tsis ntev los no, nrog kev qhia ntawm precision pwm thiab kev ua haujlwm siab ua pwm (nrog cov neeg xav tau rau pwm ntau dua tau ua kom muaj kev nce qib. Vim yog cov kev txwv ntawm ntau yam kev mob tooj liab hluav taws xob, lawv tsis tuaj yeem ua tau raws li kev txhim kho uas yuav tsum tau ua lag luam pwm. Graphite electrodes, raws li Edm electrode cov ntaub ntawv, tau siv dav hauv cov pwm lag luam vim lawv lub peev xwm txiav, kev nthuav dav nrawm, kev poob qis, thiab yooj yim thiab yooj yim. Nws tau dhau los ua tsis dhau los hloov cov hluav taws xob tooj liab.
