Emhlabeni wokumba, ukuvela kwe-PDC (Polycrystalline Diamond Compact) Cutter) kube ngumguquki womdlalo womkhakha kawoyela negesi. Eminyakeni edlule, abasiki be-PDC bake bathola izinguquko ezinkulu ekwakhiweni nasekusebenzeni, bathuthukisa ukusebenza kwabo futhi bandise isikhathi sabo sokuphila.
Ekuqaleni, abasiki be-PDC benzelwe ukuhlinzeka ngenye indlela ehlala isikhathi eside futhi ephumelelayo kuya ekusetshenzisweni kwe-Carbide yendabuko kweTungsten. Bethulwa okokuqala ngeminyaka yo-1970 futhi basheshe bathola ukuthandwa ngenxa yekhono labo lokubekezelela amazinga okushisa aphezulu nezingcindezi ezisetshenziselwa ukudonsa okujulile. Kodwa-ke, abasiki be-PDC bokuqala balinganiselwe ngemvelo yabo ye-brittle futhi babethambekele ekuphumeni nasekuqhekekeni.
Njengoba ubuchwepheshe buthuthukile, abakhiqizi baqala ukuzama izinto ezintsha nemiklamo yokwenza ngcono ukusebenza kwabasiki be-PDC. Enye yentuthuko ebaluleke kakhulu ukungeniswa kwe-Therccrystaltine Diamond Diamond Diamond Diamond Diamond Diamond Diamond Diamond Diamond (TSP) Cutters. Lawa masikeki abonisa ungqimba oluqinile kakhulu lwedayimane futhi akwazi ukumelana namazinga okushisa aphakeme kakhulu nezingcindezi kunabasiki bendabuko ye-PDC.
Okunye ukuphumelela okukhulu kubuchwepheshe be-PDC Cutter kwakuwukuqalwa kwama-hybrid cutter. Lezi zinto ezisikiwe zihlanganise ukuqina kwe-PDC ngokuqina kwe-tungsten Carbide ukudala ithuluzi lokusika elingaphatha ngisho nezinselelo ezipholisa kakhulu zokumba.
Eminyakeni yamuva nje, intuthuko emasu akhiqizwayo ivunyelwe ekwakhiweni kwama-geomethri ayinkimbinkimbi kuma-PDC cutters. Lokhu kuholele ekuthuthukisweni kwabasiki abakhethekile abaklanyelwe izinhlelo zokusebenza ezithile zokumba, njengokushayela okuqondayo nokucindezela okuphezulu kwengcindezi / yokushisa okushisa kakhulu.
Ukuziphendukela kwemvelo kwabasiki be-PDC kuye kwaba nomthelela omkhulu embonini kawoyela negesi. Ngamandla abo okubekezelela izimo ezedlulele futhi uhlale isikhathi eside kunamathuluzi wokusika wendabuko, abasiki be-PDC bakhuphule ukusebenza kahle kokumba futhi banciphise isikhathi sokuphumula. Njengoba ubuchwepheshe bokumba buqhubeka buqhubekisela phambili, kungenzeka ukuthi sizobona okwengeziwe ekwakhekeni kwe-PDC cutter design kanye nokusebenza.
Ekuphetheni, abasiki be-PDC bafika ngendlela ende selokhu kwethulwa kwabo ngawo-1970. Kusukela ezinsukwini zabo zokuqala njengenye indlela ehlala isikhathi eside eTungsten Carbide Insert, ekuthuthukisweni kwabasiki abakhethekile abaklanyelwe izinhlelo zokusebenza ezithile, ukuvela kwama-PDC cutters bekungekho lutho olumangazayo. Njengoba imboni kawoyela negesi iyaqhubeka nokuvela, kungangabazeki ukuthi abasiki be-PDC bayodlala indima ebalulekile ekusebenzeni kahle nasekukhiqizeni imisebenzi yokumba.
