Tungsten carbide, tseem hu ua cemented carbide, yog cov khoom tseem ceeb uas tseem ceeb heev rau ntau cov txheej txheem tsim khoom. Feem ntau cov txheej txheem hlau machining siv tungsten carbide inserts raws li cov lus qhia, raws li cov cemented carbide muaj hardness zoo heev thiab kub ua hauj lwm zoo tagnrho rau drilling, tho txawv, shaping thiab ua hlau workpieces. Feem ntau niaj hnub ntsej muag mills, tshuab dhos cov cuab yeej thiab kawg mills siv cov cuab yeej txiav.

Yuav Ua Li Cas Tungsten Carbide Inserts?
Chaw tsim khoom thiab machining khw uas cia siab rau tungsten carbide inserts rau kev kub ceev cov cuab yeej feem ntau mus txog ntau txhiab tus ntxig txhua xyoo. Cov neeg ua haujlwm tshuab ua haujlwm nrog ntau qhov ntxig txhua hnub, tso siab rau lawv txoj kev sib xyaw ua ke ntawm chemistry thiab geometry los muab cov npoo txiav uas xav tau rau kev txiav txim siab, kev kub ceev ntau lawm. Kev nkag siab txog yuav ua li cas carbide inserts raug tsim thiab yuav ua li cas cov txheej txheem tsim cov txheej txheem cuam tshuam rau lawv lub peev xwm tuaj yeem pab cov neeg ua haujlwm tshuab thiab cov tuam txhab ua kom nkag siab zoo dua lawv cov cuab yeej thiab tag nrho cov txheej txheem.

Tungsten carbide inserts muaj cov cemented carbide, uas yog tsim los ntawm kev sib xyaw ntawm cobalt thiab tungsten carbide. Tungsten carbide cov khoom nyuaj hauv qhov ntxig muab cov ntxig nrog nws qhov zoo ntawm hardness, thiab cobalt ua raws li tus neeg sawv cev khi, tuav cov ntaub ntawv sib koom ua ke. Qhov luaj li cas ntawm cov nplej tungsten raug siv cuam tshuam rau qhov ntxig lub hardness; Cov nplej loj (3-5 microns) ua rau softer, sai dua hnav cov ntaub ntawv, thaum cov nplej me me (tsawg dua 1 micron) ua rau tawv tawv heev, hnav resistant inserts. Qhov nyuaj tshaj qhov ntxig, qhov ntau nkig nws yuav. Thaum siv cov hlau tshwj xeeb tshwj xeeb, cov ntxig ntxig nrog cov nplej me me feem ntau yog siv, thaum cov khoom siv softer feem ntau yog siv rau hauv cov txheej txheem machining nrog kev cuam tshuam, uas hu rau cov ntaub ntawv tsis tshua muaj nkig, tougher inserts. Qhov piv ntawm cobalt rau tungsten carbide kuj cuam tshuam cov carbide inserts 'hardness qib; cobalt yog softer, yog li qhov ntau cobalt ib insert muaj, qhov softer nws yuav.

Tungsten carbide insert engineer tau txiav txim siab seb qib hardness yuav tsum ua tiav li cas; cov txheej txheem tsim khoom pib nrog cov khoom siv hmoov. Hmoov tungsten, cobalt thiab carbon yog milled thiab sib xyaw ua ke nrog cawv thiab dej, tsim kom muaj slurry tuab. Cov tshuaj no yog muab tso rau hauv lub tshuab ziab khaub ncaws, uas evaporates cov kua, tawm hauv cov hmoov sib tov zoo. Carbide inserts ces undergo ib tug sintering txheej txheem nyob rau hauv uas lawv tau tov nrog ib tug polymer los ua ib tug muab tshuaj txhuam, nias rau hauv ntxig-zoo li tus tuag thiab muab tso rau hauv ib tug high-kub qhov cub kom sintered. Lub polymer yog melted tawm ntawm lub inserts nyob rau hauv lub kauj ruam no, thiab cov inserts shrinks.

Tungsten carbide tej cuab yeej inserts yog cov ntaub ntawv hloov tau rau cov cuab yeej txiav uas feem ntau muaj qhov tseeb txiav ntug. Cov cuab yeej txiav cov ntaub ntawv muaj xws li tho txawv, kev tsim kho, txiav tawm thiab sib cais, drilling, grooving, hobbing, milling, mining, sawing, shearing thiab txiav, tapping, threading, tig, thiab nres rotor tig.
