EDMinzira yekugadzira iyo inonyanya kushandisa discharge electrode (EDM electrode) ine chaiyo geometry kupisa geometry ye electrode pane simbi (conductive) chikamu.Iyo EDM maitiroinowanzoshandiswa mukugadzirwa kwekuvhara uye kukanda kufa.
Iyo nzira ye dimensional processing yezvigadzirwa nekushandisa iyo corrosion phenomenon inogadzirwa ne spark discharge inonzi EDM.EDM is spark discharge mumhepo yemvura pane yakaderera voltage renji.
EDM imhando yekuzvipa-excited discharge, uye maitiro ayo ndeaya anotevera: Iwo ma electrode maviri e spark discharge ane high voltage isati yabuda.Apo ma electrode maviri ari pedyo kune mumwe nemumwe, mushure mokunge svikiro riri pakati pavo raputsika, kubuda kwe spark kunoitika pakarepo.Nekuparara kwemaitiro, kupikisa pakati pema electrode maviri kunoderera zvakanyanya, uye voltage pakati pema electrode maviri zvakare inoderera zvakanyanya.Iyo spark chiteshi inofanirwa kudzimwa nenguva mushure mekuchengetedza nguva pfupi (kazhinji 10-7-10-3s), kuitira kuchengetedza "inotonhora danda" hunhu hwekubuda kwe spark (kureva, simba rekupisa rekuchinja kwesimba remagetsi. haigoni kuendeswa kuhupamhi hwe electrode), kuitira kuti simba reChannel riite pamwero muduku zvikuru.Mhedzisiro yesimba remagetsi inogona kukonzera kuti electrode iite corrode.
Features:
1.EDM ndeyevasina-contact machining
Iko hakuna kusangana kwakananga pakati pechishandiso electrode uye workpiece, asi pane spark discharge gap.Mukaha uyu unowanzo kuve pakati pe0.05 ~ 0.3mm, uye dzimwe nguva unogona kusvika 0.5mm kana kutokura.Iyo gap yakazadzwa nemvura yekushanda, uye iyo yakanyanya kudzvanywa Pulse discharge, discharge corrosion pane workpiece.
2.Can "kukunda kuoma nekupfava"
Sezvo EDM inoshandisa zvakananga simba remagetsi uye simba rinopisa kuti ribvise zvinhu zvesimbi, hazvinei nesimba uye kuoma kwezvinhu zvekushanda, saka zvinyoro zvinyoro electrodes zvinogona kushandiswa kugadzirisa zvakaoma kushanda kuti zvibudirire "kunyorova kunokunda kusimba".
3.Can kugadzirisa chero yakaoma-ku-machine simbi zvinhu uye conductive zvinhu
Sezvo kubviswa kwezvinhu panguva yekugadziriswa kunowanikwa nemagetsi uye ekupisa mhedzisiro yekuburitsa, iyo machinability yemidziyo inonyanya kuenderana nemagetsi conductivity uye kupisa kwezvinhu zvezvinhu, senge kunyungudika, nzvimbo yekubikira, chaiyo kupisa simba, thermal conductivity, resistivity. , nezvimwewo, nepo inenge Iine chekuita nemagetsi ayo (kuoma, simba, nezvimwewo).Nenzira iyi, inogona kutyora zvipimo zvematurusi ekucheka echinyakare pamaturusi, uye inogona kuona kugadziridzwa kweakaoma uye akaomarara maturusi ane maturusi akapfava, uye kunyange superhard zvinhu zvakaita se polycrystalline diamond mitsara uye cubic boron nitride inogona kugadziriswa.
4.Complex shaped surfaces inogona kugadzirwa
Sezvo chimiro chechishandiso che electrode chinogona kungoteedzerwa kune workpiece, inonyanya kukodzera kugadziridzwa kwezvishandiso zvine maumbirwo akaomarara epamusoro, senge yakaoma cavity mold processing.Kunyanya, kutorwa kwenhamba yekudzora tekinoroji kunoita kuti ive chokwadi kushandisa ma electrode akareruka kugadzirisa zvikamu zvine maumbirwo akaomarara.
5.Zvikamu zvine zvinodiwa zvakakosha zvinogona kugadziriswa
Inogona kugadzirisa zvikamu zvine zvakakosha zvinodiwa senge dzakatetepa-madziro, elastic, yakaderera-kuomarara, makomba madiki, maburi akasarudzika, maburi akadzika, nezvimwe, uye anogona zvakare kugadzira mavara madiki pane mold.Sezvo mudziyo electrode uye workpiece vasiri zvakananga kuonana panguva machining, hapana kucheka simba nokuda machining, saka zvakakodzera machining yakaderera-kuoma workpieces uye micromachining.
EDM imwe yemhando yekugadzira michina, tinogona kukubatsira kugadzirisa dambudziko rako retsika.
Kana uine chero mibvunzo kana uchida kuda chero tsika sevhisi nezve CNC Machining, ndapota taura nesu zvakasununguka.
