I-Tungsten carbide, ekwabizwa ngokuba yi-cemented carbide, sisixhobo esixabisekileyo esibaluleke kakhulu kwiinkqubo ezininzi zokuvelisa. Uninzi lweenkqubo zokwenziwa kwesinyithi zisebenzisa i-tungsten carbide efakwe njengeengcebiso zesixhobo, njengoko i-carbide enesamente inobulukhuni obugqwesileyo kunye neempawu zokumelana nobushushu ezilungele ukugrumba, ukukruqula, ukubumba kunye nokwenza izixhobo zokusebenza zetsimbi. Uninzi lwezixhobo zanamhlanje zobuso, izixhobo ze-lathe kunye ne-End mills zisebenzisa ezi zixhobo zokusika.

Zenziwa njani iiTungsten Carbide Insert?
Iivenkile zokuvelisa kunye noomatshini ezixhomekeke ekufakeni i-tungsten carbide kwisixhobo sesantya esiphezulu zihamba kumawaka okufakwa rhoqo ngonyaka. Abaqhubi bomatshini basebenza kunye nokufakwa okuninzi ngosuku ngalunye, bexhomekeke kwinhlanganisela yabo eyinkimbinkimbi yekhemistri kunye nejometri ukubonelela ngeemida zokusika ezifunekayo ngokuchanekileyo, ukuveliswa kwesantya esiphezulu. Ukuqonda indlela ukufakwa kwe-carbide eyenziwa ngayo kunye nendlela iinkqubo zokuvelisa i-insert ezichaphazela amandla abo kunokunceda abaqhubi bomatshini kunye nabavelisi baqonde ngcono izixhobo zabo kunye neenkqubo ezipheleleyo.

Ukufakwa kwe-tungsten carbide kubandakanya i-carbide ene-cemented, eyenziwa ngokudibanisa i-cobalt kunye ne-tungsten carbide. Iinqununu ezinzima ze-Tungsten carbide ngaphakathi kwe-insert zibonelela ngokufakela kunye neempawu zayo zobunzima, kwaye i-cobalt isebenza njenge-agent edibeneyo, ibambe izinto eziqinileyo kunye. Ubungakanani beenkozo ze-tungsten ezisetyenziswayo zichaphazela ubunzima bokufaka; Iinkozo ezinkulu (i-3-5 microns) zikhokelela kwizinto ezithambileyo, ezikhawulezayo ezinxitywayo, ngelixa iinkozo ezincinci (ezingaphantsi kwe-1 micron) zibangela ukuba ziqine kakhulu, zifake izinto ezifakelwayo. Ubunzima bokufaka, kokukhona kuya kuba brittle. Xa kusetyenzwa iintsimbi ezinobunzima obukhethekileyo, ufakelo oluqinileyo oluneenkozo ezincinci ludla ngokusetyenziswa, ngelixa ukufakwa okuthambileyo kusetyenziswa rhoqo kwiinkqubo zobuchwephesha ngokusikeka okuphazamisekileyo, okubiza imathiriyeli engenabuqhophololo, eqinile yokufaka. Umlinganiselo we-cobalt kwi-tungsten carbide nayo ichaphazela amanqanaba obunzima bokufaka i-carbide; I-cobalt ithambile, ngoko ke i-cobalt iqulethe i-cobalt, iya kuba thambileyo.

Injineli ye-tungsten carbide insert inqume ukuba yeyiphi inqanaba lobunzima ekufuneka liphunyezwe; inkqubo yokuvelisa iqala ngezinto eziyimpuphu ekrwada. I-tungsten yomgubo, i-cobalt kunye nekhabhoni ziyasilwa kwaye zidityaniswe kunye notywala kunye namanzi, zidale uludaka olungqindilili. Le nto ifakwa kwindawo yokomisa, ekhupha ulwelo, ishiye umgubo oxutywe kakuhle. I-Carbide ifakela emva koko iqhube inkqubo ye-sintering apho ixutywe kunye nepolymer ukwenza i-paste, icinezelwe kwi-insert-shaped dies kwaye ifakwe kwisithando somlilo esikhulu ukuba sifakwe. I-polymer iyancibilika ngaphandle kokufakwa ngeli nyathelo, kwaye ukufakwa kuyancipha.

I-Tungsten carbide yokusika izixhobo ezifakelweyo zizincamatheliso ezinokufakelwa endaweni yezixhobo zokusika ezikholisa ukuqulatha eyona kona yokusika. Izixhobo zokusika izixhobo zokufaka izixhobo ziquka ukukruqula, ukwakhiwa, ukunqunyulwa kunye nokwahlula, ukubhola, ukugrumba, ukubhobhoza, ukugaya, ukugaya, ukuchithwa, ukucheba kunye nokusika, ukucofa, ukuthunga, ukujika, kunye nokujika kwe-rotor.
