Kwihlabathi lokuqhuba, indaleko ye-PDC (i-Polycrystalline yeDayimane iDayide) ingumdlalo we-oyile kunye negesi. Kwiminyaka edlulileyo, abasikisi be-PDC benziwe iinguqu ezibalulekileyo kuyilo kunye nokusebenza, ukuphucula ukusebenza kwabo nokwandisa ubomi babo.
Ekuqaleni, ii-pds ezisikitikela ze-PDC zenzelwe ukubonelela ngenye indlela eyomeleleyo nefanelekileyo yokufakwa kwe-tungsten yemveli. Baqala bazisa nge-1970s kwaye bekhawuleza bafumana ukuthandwa ngenxa yokukwazi kwabo ukumelana nobushushu obuphakamileyo kunye noxinzelelo kwizicelo ezinzulu zokumba. Nangona kunjalo, amathayitha okuqala kwe-PDC anqunyelwe bubume babo brittle kwaye athambekele ekuqhubeni nokuqhawula.
Njengoko itekhnoloji ihambele phambili, abavelisi baqalisa ukuzama izixhobo ezintsha kunye nokuyila ukuphucula intsebenzo ye-PDC. Enye yezona zinto zibalulekileyo yayikukwazisa nge-polycrystalline ye-polycrystalline yedayimane (i-TSP). Aba basika babonisa ungqimba olunamandla lwedayimani kwaye banokumelana namaqondo obushushu aphezulu kunye noxinzelelo kunee-PDC ze-PDC zeMveli.
Omnye umtshato ophambili kwitekhnoloji ye-PDC yayikukuqaliswa kwe-hybrid castters. Aba basika badibene ngomoya we-PDC kunye nobunzima be-tungsten carbide ukuba benze isixhobo esisikiweyo esinokukwenza izicelo zokunxila.
Kwiminyaka yakutshanje, ukuqhubela phambili kwiindlela zokwenza imveliso zivumele ukudalwa kweejometri ezintsonkothileyo kwi-pdct. Oku kukhokelele ekuphuhlisweni kweemitha ezikhethekileyo ezenzelwe ukuntywila okuthe ngqo, njengokubulala kunye nokucinezela okuphezulu / ubushushu obuphezulu.
Indaleko ye-pdc cutters inefuthe elibonakalayo kwishishini leoyile negesi. Ngamandla abo okumelana neemeko ezigqithisileyo kwaye zigqibele ixesha elide kunezixhobo zokusika, ii-PDC zikhulise ukusebenza kakuhle kunye nexesha lokuncitshiswa. Njengoko itekhnoloji yokuqhuba iyaqhubeka ukuqhubela phambili, kunokwenzeka ukuba siza kubona ezinye izinto kwi-PDC yoyilo kunye nokusebenza.
Ukuqukumbela, ukusika i-PDC kufike ixesha elide ukusukela oko kwazo ngo-1970. Ukusuka kwiintsuku zabo zokuqala njengenye indlela eyomeleleyo yokufaka i-tungsten ye-tungsten, kuphuhliso lweendawo eziziintloko ezikhethekileyo ezenzelwe ukuntywila, indaleko yabasika i-PDC ayikho into emfutshane kakhulu. Njengoko ishishini leoyile kunye nerhasi liyaqhubeka nokuvela, ukusika igesi ngokungathandabuzekiyo kuya kudlala indima ebalulekileyo ekuqhubeni ukusebenza kunye nemveliso ekuthandeni imisebenzi.
