Txais tos hu rau peb rau kev hais.
Hauv hluav taws xob tshem tawm Machining (edm), graphite cov ntawv tau hloov kho cov khoom siv ntau dua rau kev ua haujlwm kho mob. Tsis zoo li cov hluav taws xob Copeples, graphite muaj cov txiaj ntsig tshwj xeeb uas ua rau nws xaiv rau qhov siab {1} pre{- effecticed edm kev ua haujlwm.
EDM ua haujlwm los ntawm kev tsim hluav taws xob ntawm cov hluav taws xob nruab nrab ntawm cov electrode thiab ib qho chaw ua haujlwm, eroding khoom kom ua tiav cov duab uas xav tau. Graphite exels ntawm no rau nws qhov hluav taws xob zoo, qis melting point (~ 3,600 degree), thiab tsis kam rau cua sov. Tsis zoo li tooj liab, uas softens ntawm kev kub siab, graphite tswj cov qauv txheej txheem kev ntseeg siab thaum lub sijhawm muaj kev ncaj ncees, ua rau cov khoom siv ceev ceev. Piv txwv li, graphite electrodes tuaj yeem txiav cov tawv tawv steel 2-3x sai dua tooj liab.
Lwm qhov txiaj ntsig tseem ceeb yog machinility. Graphite yog nkig me tab sis yooj yim rau cov cuab yeej siv nrog cov cuab yeej siv tau (piv txwv li cas} Qhov kev sib piv nrog tooj liab nrog tooj liab, uas yuav tsum tau sib tsoo loj me me rau cov yam ntxwv zoo. Tsis tas li ntawd, grapite cov khoom siv tsawg nqi (txheeb ze rau tooj liab) thiab minimal post {} kev ua haujlwm (tsis muaj kev ua haujlwm (tsis muaj kev ua haujlwm deburring) txo cov nuj nqis ntau dua.
Cov ntawv thov SPIN kev lag luam: Hauv pwm - muaj duab tsim, graphite hluav taws xob tsim cov kab nrib pleb; Hauv Aerospace, lawv lub tshuab xev xb cua nrog rau kev tiv thaiv nruj. Tsis ntev los no nce qib, xws li ultra- loj {} loj - edm, qhov twg precision yog qhov tseem ceeb. Raws li Edm thev naus laus zis hloov zuj zus, cov hluav taws xob graphite txuas ntxiv mus teeb tsa tus qauv rau versatility thiab tus nqi {{} ua hauj lwm zoo.
