Kwiminyaka yakutshanje, itekhnoloji yokuqhuba ihambile kakhulu, kwaye enye yezinto eziphambili zokuqhuba olu tshintsho luyisikithi se-PDC. I-PDC, okanye i-polycrystalline yedayisi, i-cutters luhlobo lwesixhobo sokuntywila esisebenzisa indibaniselwano yedayimani kunye ne-tungsten carbide ukuphucula intsebenzo kunye nokuqina. Aba basika baye badume ngakumbi kwishishini leoyile negesi kunye nezinye izicelo zokuntywila.
Ii-PDC ezisikimitha ze-PDC zenziwa ngamasuntswana edayimani yedayimani kwi-tungsten ye-tungsten kwiqondo lobushushu kunye noxinzelelo. Le nkqubo idala umbandela onzima kwaye udinwe ngakumbi ngaphandle kwezixhobo zokumba eziqhelekileyo. Isiphumo sisisikithi esinokumelana nobushushu obuphakathi, uxinzelelo, kunye ne-abrasion kunezinye izinto ezisikiweyo, ezivumela ukuqhuba okukhawulezileyo kunye nokusebenza ngokufezekileyo.
Izibonelelo zoncedo lwe-PDC zininzi. Kwabanye, banokunciphisa ixesha lokuntywila kunye neendleko ngokunika amandla ngokukhawuleza nangokufanelekileyo ngakumbi. Ii-PDC ezisikimitha ze-PDC nazo zinokuthamba nje ukunxiba kunye nomonakalo, onciphisa isidingo sokutshintshwa rhoqo nokulondolozwa. Oku kugcina iinkampani ixesha kunye nemali ekuhambeni kwexesha.
Elinye iNzuzo ye-PDC yokusika i-PDC iguquguqukayo. Banokusetyenziswa kwizicelo ezahlukeneyo zokuntywila, kubandakanya ukuqhuba ioyile kunye negesi, ukuqhuba kwegesi, imigodi, kunye nolwakhiwo. Zikwahambelana neendlela ezahlukeneyo zokumbamba, ezinje nge-teraring yokuqhuba, ukuqhuba ngokusondeza, kunye nokugqobhoza ngokuthe tyaba.
Ukusetyenziswa kwee-CDT ze-PDC kukwakhokelela ekunciphiseni kwempembelelo kwendalo. Ukuqhuba ngokukhawuleza nangokufanelekileyo kuthetha ixesha elincinci elichithwe kwindawo, enciphisa inani lamandla kunye nezixhobo ezifunekayo. Ukongeza, ii-pdc ezisikitikileyo zinokwenzeka ukuba zibangele ukonakala kwindawo engqongileyo, enjengemithombo yamanzi kunye nemithombo yamanzi ephantsi komhlaba.
Ukuthandwa kwee-cutter ze-PDC kulindeleke ukuba zikhule kwiminyaka ezayo. Ngapha koko, imakethi yehlabathi ye-PDC iqinisekisiwe ukuba ifikelele kwi-1.4 yezigidigidi ezingamawaka angama-2025, iqhutywa ngokunyuka kwemfuno ukusuka kwishishini leoyile kunye negesi kunye nezinye izicelo zokuqhuba.
Ukuqukumbela, ukusika i-PDC ineetekhnoloji yokuqhuba ngokuguqukayo kunye nokusebenza kwabo okuphezulu, ukuqina, ukusebenzisa izibonelelo zokusingqongileyo. Njengoko imfuno yezixhobo ezisikiweyo iyaqhubeka, kucacile ukuba ii-PDC ezisikiweyo zilapha ukuze zihlale kwaye ziya kuqhubeka zidlala indima ebalulekileyo ekuqhubeni ishishini lokuqhuba.
