Qhov chaw ntawm precision EDM
Raws li kev siv tshuab precision machining, precision EDM yuav tsum ua raws li qhov tseem ceeb yog siv cov cuab yeej siv tshuab precision machining. Vim tias thaum siv cov cuab yeej siv tshuab rau machining, txawm li cas los xij, qhov tseeb machining yuav tsis dhau qhov tseeb ntawm cov cuab yeej siv tshuab. Yog tias qhov tseeb ntawm cov cuab yeej siv tshuab tsis txaus, qhov tseeb machining ntawm EDM yuav raug txwv, thiab txawm tias cov khoom siv EDM zoo tshaj plaws yuav poob nws qhov chaw. Rau EDM ntawm tus nqi siab ntxiv pwm qhov chaw, cov cuab yeej tawm tshuab dav dav tsis muaj peev xwm ua kom tiav, thiab kev xaiv cov cuab yeej siv tshuab EDM high-precision yog qhov tsim nyog ua ntej. Cov cuab yeej siv tshuab no muaj qib siab ntawm automation thiab kev txawj ntse zoo heev, uas tuaj yeem txo qhov kev cia siab ntawm kev ua haujlwm zoo ntawm tib neeg yam.
Ntxiv rau qhov ua tau raws li qhov yuav tsum tau muaj ntawm high-precision EDM nyob rau hauv cov nqe lus ntawm cov khoom siv ntawm cov qauv thiab ntau yam geometric raug ntawm cov spindle thiab workbench, cov cuab yeej siv tshuab precision no tseem tuaj yeem tau txais qhov tsis siv neeg siab tsis siv neeg tso qhov tseeb los ntawm tag nrho kaw-voj tswj hom ntawm high-precision grating kav. Kev ua haujlwm ntawm lub zog hluav taws xob ntawm lub tshuab cuab yeej ncaj qha txiav txim siab qhov ua tau zoo ntawm EDM. Yuav kom ua tiav qhov raug siab dua, nws yuav tsum muaj qhov sib txawv ntawm qhov paug tawm yuav tsum me me li sai tau. Qhov sib txawv ntawm qhov ruaj khov yog nyob ntawm cov cuab yeej siv hluav taws xob nrawm nrawm, kom cov khoom siv pov tseg thiab cov tar tuaj yeem tawm tau zoo. Nyob rau hauv cov xwm txheej ntawm qhov sib txawv me me machining, nws muaj peev xwm paub qhov ruaj khov machining, cia li saib xyuas lub xeev ntawm txhua tus mem tes tawm, thiab xyuas kom meej tias cov mem tes tsis zoo tsis tsim kev puas tsuaj.
Precision machining tshuab cov cuab yeej yuav tsum tau txais kev ua haujlwm siab servo tswj qhov system, kom lub machining qhov tob yuam kev tuaj yeem tswj tsis pub dhau qhov tsawg kawg nkaus kom tau raws li qhov yuav tsum tau ua ntawm high-precision machining. Hauv kev ua tiav machining, ntau txoj kev co, xws li angular clearance translation, spherical translation, thiab lwm yam, tuaj yeem siv los them nyiaj rau qhov loj ntawm qhov profile. Kev siv cov waveforms nrog txoj kab nqes tswj pab kom ua tiav qhov tsis tshua muaj hluav taws xob tsis zoo thiab cov txheej txheem qib siab.
Cov kev xav tau rau electrodes hauv precision ignition processing
Rau cov electrodes siv nyob rau hauv precision EDM, nws yog ib qho tsim nyog los xyuas kom meej qhov zoo, yog li cov txheej txheem raug siv yuav tsum tau siv kom ua tiav. Feem ntau, kev tsim ntawm precision electrode yog ua tiav los ntawm high-speed machining chaw. Tom qab machining, nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua uas tsis tas yuav tsum tau ua ntau npaum li qhov ua tau. Txawm hais tias nws tsim nyog, nws tsuas yog phau ntawv xov thiab polishing. Qhov no yog ua kom tsis txhob muaj kev cuam tshuam ntawm cov txheej txheem tom ntej ntawm cov electrode ntawm qhov tseeb ntawm cov electrode, tab sis nws kuj muab cov kev cai nruj dua rau kev tsim cov txheej txheem ntawm electrode.
Cov khoom siv hluav taws xob kuj yog qhov teeb meem tseem ceeb hauv kev ua haujlwm precision. Liab tooj liab yog cov khoom siv hluav taws xob siv dav tshaj plaws hauv kev siv hluav taws xob machining, uas tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm high precision machining. Txawm li cas los xij, nyob rau hauv micro machining, thiaj li yuav txo tau electrode poob, txo cov electrodes, txhim kho lub machining nto zoo, thiab ua tiav machining siab thiab ruaj khov, tooj liab tungsten alloy electrode cov ntaub ntawv nrog tus nqi siab yuav tsum xav txog.
Qhov loj thiab cov duab ntawm electrode yuav tsum tau ntsuas kom meej ua ntej siv hauv EDM, thiab nws tsuas yog siv tau rau machining tom qab dhau qhov kev tshuaj ntsuam xyuas. Hauv kev tsim khoom thiab kev ua haujlwm tiag tiag, muaj ntau qhov xwm txheej los ntawm cov khoom siv hluav taws xob tsis tsim nyog. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xyuam xim rau kev tsim cov electrodes hauv precision machining.
