Qhov zoo ntawm cov ntaub ntawv graphite hauv EDM ua

Yav dhau los, EDM hauv pwm tsim feem ntau siv tooj liab ua cov khoom siv electrode. Nrog rau qhov nce ntawm tus nqi ntawm cov khoom siv tooj liab thiab kev nce qib ntawm graphite thev naus laus zis, tus nqi ntawm cov khoom siv graphite tau raug txo, thiab graphite tau nce dav siv los ua cov khoom siv hluav taws xob rau hluav taws xob tawm machining. Piv nrog rau tooj liab, graphite cov ntaub ntawv muaj ntau yam zoo.

1. Zoo machinability

Kev txiav tsis kam ntawm cov khoom siv graphite yog me dua, thiab nws cov kev ua haujlwm zoo yog li 2 ~ 3 npaug ntawm tooj liab. Kev siv cov khoom siv graphite tuaj yeem txo lub sijhawm ua haujlwm ntawm cov electrode.

2. Nws yog qhov yooj yim dua kom paub txog kev ua cov duab nyias nyias

Kev txiav cov cua sov uas tsim los ntawm kev ua cov tooj liab electrodes yog qhov ua rau thermal deformation. Vim yog cov yam ntxwv ntawm nws cov khoom yas, nws tseem ua rau elastic deformation thaum ua cov duab nyias nyias, ua rau kev vibrations; thaum graphite nws tus kheej yog ua los ntawm sintered hais, thiab nws cov khoom kub-resistant thiab brittle cov khoom yuav txo tau deformation thiab vibration thaum ua.

3. Zoo heev EDM roughing efficiency

Lub melting point ntawm tooj liab yog 1083 degree, thiab instantaneous kub ntawm paug tuaj yeem ncav cuag 1100 degree. Nws yooj yim dua rau hnav tooj liab electrodes, thiab graphite yuav sublime ntawm 3550 degree,tYog li ntawd, graphite electrode yog yooj yim dua los tiv taus siab tam sim no, thiab tuaj yeem ua tiav cov electrode tsawg dua.

4. Qhov hnyav dua

Qhov ceev ntawm graphite tsuas yog 1/5 ntawm cov tooj liab, thiab kev siv cov graphite electrodes tuaj yeem txo cov load ntawm lub taub hau ntawm lub tshuab thaum lub sij hawm.EDMtshuab.

5. Me me thermal expansion tus nqi

Lub thermal expansion tus nqi ntawm graphite yog 1/4 ntawm cov tooj liab, uas tuaj yeem txo qhov yuam kev los ntawm thermal deformation ntawm electrode thaum tawm.
