Tsebo ea Motheo ea PDC Cutter

PDC e emetse polycrystalline diamond compact. Ha e le hantle, PDC bit e sebelisa sephaphatha sa taemane se chitja se hokahaneng le setsi sa carbide e le mokhoa oa mantlha oa ho itšeha. Taemane e entsoe ka polycrystalline 'me e na le melemo ea ho tšoarella nako e telele hammoho le ho itšeha.

Taemane e entsoeng ka maiketsetso e hanyetsana le ho khoptjoa ka makhetlo a 150 ho feta carbide. E ntlafalitsoe ke GE, litaemane tsena hangata li fanoa e le motsoako oa maiketsetso o entsoeng ka bongata o entsoeng ka tlas'a mocheso o phahameng le khatello ea ho etsa liphaphatha tsa taemane tse nepahetseng.

Ts'ebetso ea leaching ka lik'hemik'hale e tlosa cobalt catalyst ho tloha PDC microstructure. PDC diamond leaching ke mohato oa bohlokoa oa ts'ebetso o eketsang bophelo bo bolelele le ts'ebetso ea bit.

Ka mor'a moo, li-wafers li kopantsoe le li-bases tsa carbon. Setsi sena sa carbide se sebetsa mesebetsi e 'meli. Ntlha ea pele, li fana ka mokhoa o tiileng oa ho tšehetsa liphaphatha tsa taemane. Ea bobeli, e fana ka mokhoa oa ho hokela daemane ho 'mele o monyenyane kaha ha o khone ho rekisa kapa ho cheselletsa litaemane. Sepheo ke ho fana ka sehahi se tšoarellang ha u ntse u eketsa litekanyetso tsa ho kenella.

Karolo ea daemane karolong e ka tlaase ea carbide ea PDC bit e bitsoa cutter. Li tla ka mefuta e meraro ea boholo ba bophara ba 13mm, 16mm, le 19 mm. Haholo-holo PDC bit e sebelisa 1308 seha.

Tšobotsi e 'ngoe ea bohlokoa ea li-cutters tsa daemane ke chamfer, e leng angle ea bohale ba daemane. Karolo ena e na le bohlokoa bo boholo ho moralo le ts'ebetso. Ha ho li-cutters (zero degrees) tse sehang ha li sebelisoe hangata, 'me li ka sebelisoa feela mobung o bonolo kaha li tloaetse ho phunya. Chamfer ea likhato tse 12 ke khetho e potlakileng ea ho kenella. Ba ntse ba le tšekamelo ea ho chepping habonolo. Zzbetter e ka etsa chamfer ho latela litlhoko tsa moreki.

Motheo oa carbide o bohlokoa haholo ts'ebetsong ea sehahi. Li-cutters tsa boleng bo holimo li hokahantsoe le metheo e loketseng e nang le li-grid tse nepahetseng. Lisebelisoa tsa boleng bo tlaase li tla etsa hore ho be le kopano ea boleng bo tlaase ea sehahi.

Motheo oa carbide o bohlokoa haholo ts'ebetsong ea sehahi. Li-cutters tsa boleng bo holimo li hokahane le metheo e metle e nang le li-grid tse nepahetseng, athe metheo ea boleng bo tlase e tla etsa kopano ea boleng bo tlase ba sehahi.

PDC ea boleng bo holimo e hlokometsoeng hantle le ho sebelisoa ha e sebelisoa libakeng tse loketseng joalo ka sandstone e ngotsoe hore e tšoarelle nako e telele haholo.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
