Hlau Txiav Electrical Discharge Machining (WEDM)
Hluav taws xob tawm hlau txiavyog luv rau hlau txiav. Nws yog tsim nyob rau hauv lub hauv paus ntawm hluav taws xob spark perforation thiab tsim ua.
Nws tsis tau tsuas yog tsim daim ntawv thov ntawm EDM, tab sis kuj hloov EDM xuas nrig ntaus thiab tsim hauv qee yam. Niaj hnub no, cov cuab yeej siv tshuab hlau txiav tau suav rau feem ntau ntawm EDM tshuab cuab yeej.
Hlau Txiav Electrical Discharge Machining (WEDM), ib qeb ntawm kev ua hluav taws xob, yog yav dhau los Soviet Union los ntawm Lazarinko ob peb kev tshawb fawb hloov kev sib cuag los ntawm cov hluav taws xob tawm corrosion puas tshwm sim thiab ua rau, Nws tau pom tias qhov kub siab ntawm cov hluav taws xob hluav taws xob tuaj yeem yaj, oxidize thiab corrode cov hlau hauv zos, yog li tsim thiab inventing txoj kev ntawm hluav taws xob paug machining.
Lub tshuab txiav hlau kuj tau tsim nyob rau hauv 1960 nyob rau hauv lub qub Soviet Union, thiab Tuam Tshoj yog thawj lub teb chaws siv nws nyob rau hauv industrial ntau lawm. Lub hauv paus ntsiab lus ntawm lub cev yog tias dawb ions zoo thiab cov hluav taws xob sib sau ua ke hauv thaj chaw thiab sai sai tsim cov ionized conductive channel. Nyob rau theem no, ib qho hluav taws xob tam sim no tsim ntawm daim hlau. Ua rau muaj kev sib tsoo ntau ntawm cov khoom, ua rau thaj tsam plasma uas sai sai rau qhov kub ntawm 8,000 txog 12,000 degrees, tam sim ntawd melting qee yam khoom ntawm ob lub conductors.
Nyob rau tib lub sijhawm, lub npuas yog tsim los ntawm vaporization ntawm cov electrode thiab cov kua dej dielectric, thiab nws lub siab nce tsis tu ncua kom txog thaum nws siab heev. Tom qab ntawd qhov tam sim no cuam tshuam, qhov kub thiab txias poob dheev, ua rau cov npuas tawg sab hauv, qhov tshwm sim lub zog cuam tshuam cov khoom tawg tawm ntawm qhov hluav taws xob, thiab tom qab ntawd cov khoom siv corroded recondenses rau hauv me me spheres hauv cov kua dielectric, thiab tawm los ntawm dielectric. kua dej. Tom qab ntawd los ntawm kev saib xyuas thiab kev tswj hwm ntawm NC tswj, servo mechanism ua kom tiav, kom qhov tshwm sim tawm yog ib yam, thiaj li ua tiav cov txheej txheem ua tiav, kom nws dhau los ua qhov yuav tsum tau muaj qhov loj thiab cov duab raug ntawm cov khoom.
Reciprocating hom High Speed Wire cut Electrical Discharge yuav muab faib ua reciprocating hom kev kub ceev hlau txiav hluav taws xob tawm Low Speed one-way walk Wire cut Electrical Discharge Tsawg ceev ib-txoj kev taug kev hlau txiav hluav taws xob tawm Feem ntau hu ua "slow Wire" hauv Machining ) thiab Vertical Wire Electrical Discharge Machining machine tool With Rotation Wire. Raws li daim ntawv ntawm lub rooj yuav muab faib ua ib kem ntoo khaub lig lub rooj hom thiab ob kab kem (feem ntau hu ua gantry hom).
