I-Tungsten carbide, eyaziwa nangokuthi i-cemented carbide, iyimpahla eyigugu ebaluleke kakhulu ezinqubweni eziningi zokukhiqiza. Izinqubo eziningi zomshini wensimbi zisebenzisa okufakwayo kwe-tungsten carbide njengamathiphu amathuluzi, njengoba i-carbide enosimende inokuqina okuhle kakhulu kanye nezindawo zokumelana nokushisa ezilungele ukubhola, ukubhora, ukubumba kanye nokwenza izingcezu zensimbi. Izigayo eziningi zanamuhla zobuso, amathuluzi e-lathe nezigayo zokugcina zisebenzisa la mathuluzi okusika.

I-Tungsten Carbide Insert yenziwa kanjani?
Izitolo zokukhiqiza nezomshini ezithembele ekufakweni kwe-tungsten carbide ngamathuluzi esivinini esikhulu ngokuvamile zidlula ezinkulungwaneni zokufakwa njalo ngonyaka. Abaqhubi bemishini basebenza ngokufaka okuningi usuku ngalunye, bethembele ekuhlanganiseni kwabo okuyinkimbinkimbi kwekhemistri nejiyomethri ukuze banikeze imiphetho edingekayo ukuze kutholakale ukunemba, ukukhiqizwa kwesivinini esikhulu. Ukuqonda ukuthi ukufakwa kwe-carbide kwenziwa kanjani nokuthi izinqubo zokukhiqiza ezifakiwe ziwathonya kanjani amandla abo kungasiza abaqhubi bemishini nabakhiqizi baqonde kangcono amathuluzi abo nezinqubo zizonke.

Ukufakwa kwe-tungsten carbide kuhlanganisa i-carbide enosimende, eyenziwe ngenhlanganisela ye-cobalt ne-tungsten carbide. Izinhlayiya eziqinile ze-Tungsten carbide ngaphakathi kokufakiwe zinikeza okufakiwe ngezimfanelo zayo zobulukhuni, futhi i-cobalt isebenza njenge-ejenti ebophayo, ibambe izinto eziqinile ndawonye. Ubukhulu bezinhlamvu ze-tungsten ezisetshenziswayo buthinta ubulukhuni bokufaka; okusanhlamvu okukhulu (ama-microns angu-3-5) kubangela izinto zokufaka ezithambile, eziguga ngokushesha, kuyilapho izinhlamvu ezincane (ezingaphansi kwe-micron engu-1) ziphumela ekufakweni okuqinile, okugqokayo okuqinile. Uma ukufakwa kuba nzima, kuzoba brittle kakhulu. Uma kwenziwa izinsimbi ezinobunzima obukhethekile, ukufaka okuqinile okunohlamvu oluncane ngokuvamile kusetshenziswa, kuyilapho okufakwayo okuthambile kusetshenziswa kakhulu ezinqubweni zomshini ezinokusikeka okuphazamisekile, okubiza izinto zokufaka ezintengantengayo neziqinile. Isilinganiso se-cobalt ne-tungsten carbide siphinde sibe nomthelela emazingeni obulukhuni okufakwa kwe-carbide; i-cobalt ithambile, ngakho-ke uma i-cobalt iqukethe i-cobalt, izoba thambile.

Unjiniyela we-Tungsten carbide insert unqume ukuthi yiliphi izinga lobulukhuni okufanele lifinyelelwe; inqubo yokukhiqiza iqala ngezinto ezingavuthiwe eziyimpuphu. I-tungsten eyimpushana, i-cobalt nekhabhoni kuyagaywa futhi kuhlanganiswe notshwala namanzi, kudaleke udaka oluqinile. Le nto ifakwa endaweni yokomisa, ehwamulisa uketshezi, kusale impushana exutshwe kahle. Ama-carbide inserts abe esengena kwinqubo yokucwilisa lapho axutshwa khona ne-polymer ukuze enze unamathisele, acindezelwe kumafa amise okwe-insert futhi afakwe esithandweni esishisa kakhulu ukuze ashiswe. I-polymer iyancibilika ngaphandle kokufakwa phakathi nalesi sinyathelo, futhi ukufakwa kuyancipha.

Okufakwayo kwethuluzi lokusika i-Tungsten carbide kukhona okunamathiselwe esikhundleni samathuluzi okusika ngokuvamile aqukethe umphetho wangempela wokusika. Izinhlelo zokusebenza zokufaka amathuluzi okusika zihlanganisa ukubhoreka, ukwakha, ukusika nokuhlukanisa, ukubhoboza, ukugxusha, ukubhoboza, ukugaya, ukumba izimayini, ukusaha, ukugunda nokusika, ukuthepha, ukuhlanganisa, ukujika, nokujika kwe-rotor yamabhuleki.
