PDC, kapa polycrystalline diamond compact, li-cutters li fetohile tse fetolang papali indastering ea ho cheka. Lisebelisoa tsena tsa ho itšeha li fetotse theknoloji ea ho cheka ka ho eketsa bokhoni le ho fokotsa litšenyehelo. Empa li-cutters tsa PDC li tsoa hokae, hona ho tlile joang hore li tuma hakaale?
Nalane ea li-cutters tsa PDC e qalile ka bo-1950 ha litaemane tsa maiketsetso li qala ho ntlafatsoa. Litaemane tsena li ne li hlahisoa ka ho beha graphite tlas’a likhatello tse phahameng le mocheso, ho etsa thepa e thata ho feta taemane ea tlhaho. Litaemane tsa maiketsetso li ile tsa tuma ka potlako lits'ebetsong tsa indasteri, ho kenyelletsa le ho cheka.
Leha ho le joalo, ho sebelisa litaemane tsa maiketsetso ha ho cheka ho ne ho le boima. Hangata litaemane li ne li tla robeha kapa li itokolle ho sesebelisoa, li fokotsa ts'ebetso ea eona 'me li hloka ho nkeloa sebaka khafetsa. E le ho rarolla bothata bona, bafuputsi ba ile ba qala ho leka ho kopanya litaemane tsa maiketsetso le lisebelisoa tse ling, tse kang tungsten carbide, ho etsa sesebelisoa sa ho itšeha se tšoarellang haholoanyane le se sebetsang hantle.
Lilemong tsa bo-1970, li-cutters tsa pele tsa PDC li ile tsa ntlafatsoa, tse nang le lesela la daemane le kopantsoeng le substrate ea tungsten carbide. Li-cutters tsena qalong li ne li sebelisoa indastering ea merafo, empa melemo ea tsona e ile ea bonahala kapele lits'ebetsong tsa ho cheka oli le khase. Li-cutters tsa PDC li fane ka ho cheka ka potlako le ka mokhoa o atlehileng haholoanyane, ho fokotsa litšenyehelo le ho eketsa tlhahiso.
Ha thekenoloji e ntse e ntlafala, li-cutters tsa PDC li ile tsa hatela pele le ho feta, ka meralo e mecha le lisebelisoa li eketsa ho tšoarella le ho feto-fetoha ha tsona. Kajeno, li-cutters tsa PDC li sebelisoa mefuteng e mengata ea ho cheka, ho kenyeletsoa ho cheka ha mocheso oa mocheso, ho rafa, ho haha, le tse ling.
Tšebeliso ea li-cutters tsa PDC e boetse e lebisitse ntlafatsong ea mekhoa ea ho cheka, joalo ka ho phunya ho rapameng le ho cheka ka tsela e lebang. Mekhoa ena e ile ea khoneha ka lebaka la ho eketseha ha katleho le ho tšoarella ha li-cutters tsa PDC, ho lumella ho cheka ho nepahetseng le ho laoloang.
Qetellong, li-cutters tsa PDC li na le nalane e ruileng e qalileng ho nts'etsopele ea litaemane tsa maiketsetso ka bo-1950. Kholiso ea bona le nts'etsopele ea bona li lebisitse ho tsoelopele e kholo theknolojing ea ho cheka, ho ntlafatsa ts'ebetso, ho fokotsa litšenyehelo, le ho holisa mefuta e mengata ea lits'ebetso. Ha tlhoko ea ho cheka ka potlako le ka mokhoa o atlehileng haholoanyane e ntse e hola, ho hlakile hore li-cutters tsa PDC e tla lula e le karolo ea bohlokoa indastering ea ho cheka.
