Vim nws lub siab tawv thiab hnav tsis kam, carbide yog dav siv raws li cov khoom siv rau ntau yam cuab yeej tsim kev lag luam, hu ua "hniav hniav". Piv txwv, cemented carbide laum qoj ib txwm yog cov khoom siv tshuab koj Kev faib tawm thiab qhov zoo ntawm kev tso cai carbide laum cov khoom me me.
Raws li peb txhua tus paub, qhov tseeb xaiv ntawm tungsten carbide laum cov khoom lag luam yog qhov kev pab zoo rau kev txhim kho drilling tsim khoom thiab txo tus nqi ib lub qhov. Muaj plaub hom tungsten carbide hnyiab uas muaj ntau hauv lub neej, lawv yog carbide ntxig cov khoom lag luam, welded carbide hnyiab thiab hloov cutter carbide drilling. Txhua hom laum muaj cov txiaj ntsig ntawm kev tsim nyog rau kev sib tw machining premise, yog li dab tsi yog qhov zoo ntawm cov chaw ua haujlwm sib txawv?
Khoom Carbide Laum me ntsis, ua ib hom laum me ntsis nrog kev sib tsoo ua, muaj peev xwm rov sib tsoo thiab siv tau, thiab feem ntau tuaj yeem rov pib dua hauv av 7 ~ 10 zaug. Nyob rau hauv cov txheej txheem kev ua tiav, peb tuaj yeem txo peb cov nqi. Lub tungsten carbide indexable ntxig laum yog ib qho kev ntxig tsis muaj kev ua haujlwm tsis muaj nuj nqi, uas muaj qhov zoo ntawm tus nqi qis, ntau yam khoom muaj ntau yam. Lub laum me ntsis nrog tungsten carbide indexable incentable tuaj yeem machined nrog ntau qhov sib txawv yog 2D ~ 5d (d yog lub qhov taub thiab lwm yam cuab yeej ua haujlwm. Yoov nyob rau hauv cov tshuaj pleev yog tias lub tshuab ua tau ntawm cov laum me me yog qhov tsawg.
Welded carbide laum cov khoom tawg yog tsim los ntawm nroo vuam lub carbide crown ntawm cov hlau laum lub cev. Tus kheej-centre geometric txiav hom yog saws, lub zog txiav yog qhov rov qab me me, thiab lub laum me ntsis tuaj yeem rov qab 3 ~ 4 zaug. Nws cov ntsiab lus tseem ceeb yog qhov zoo heev rau kev tswj, zoo nto tas, thiab muaj kev zoo thiab muab qhov tseeb. Nws yog tsuas yog siv rau hauv machining chaw, tshuab dhos cnc los yog lwm yam siab-rigidity, high-ceev tshuab cuab yeej.
Qhov hloov lub taub hau hom hom carbide muaj ib txoj haujlwm tseem ceeb thiab muaj ntau yam diamonds, thiab muaj ntau yam diameters, uas tuaj yeem siv rau cov khoom siv sib txawv. Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm kev ua tau zoo kuj tseem zoo kawg li, lub tshuab machining yog kuj tseem muaj tsawg kawg 20 ~ 30 zaug, tuaj yeem txo tus nqi ntau lawm.
Hauv kev tsim khoom tiag tiag, thaum ua tau kev txav siab ceev, nws yog qhov tsim nyog kom muaj lub laum me ntsis nrog kev ua haujlwm rau tus kheej, uas yuav tsum tau ua raws li kev ua tau zoo thiab ua haujlwm. Ntxiv rau txoj kev ua haujlwm ntawm kev ua haujlwm, lub zog tawv tawv tawv tawv thiab cov hloov tau carbide lun me ntsis, uas tuaj yeem ncav nws li ntawm IT6-IT9 qib. Yog li ntawd, lub sijhawm no, peb yuav xaiv cov khoom tawv tawv tawv thiab hloov txiav cutter puas yog carbide laum. Nyob rau hauv nruab nrab, rigidity ntawm cov khoom carbide laum yog zoo dua.
