Li-cutters tsa Square PDC (Polycrystalline Diamond Compact) li seha lisebelisoa tse sebelisoang haholo liindastering tse fapaneng, haholo lits'ebetsong tsa ho cheka. Sebopeho sa lisekoere se bolela moralo oa geometri oa sehahi, se nang le mahlakore a mane a lekanang le li-angles tse 'nè tsa 90-degree.
Li-cutters tsa Square PDC li sebelisoa haholo indastering ea ho hlahloba oli le khase. Ke karolo ea bohlokoa ea li-drill bits, tse sebetsang e le likarolo tsa mantlha tsa ho itšeha. Sebopeho sa lisekoere se lumella ho cheka hantle ka mefuta e fapaneng ea libopeho, ho tloha ho tse bonolo ho ea ho tse thata tsa majoe.
Ts'ebetso ea ho etsa li-cutter tsa lisekoere tsa PDC e kenyelletsa mehato e mengata. Qalong, phofo ea daemane e kopantsoe le sekontiri sa tšepe, hangata cobalt, ka mokhoa o phahameng oa khatello, mocheso o phahameng. Sena se etsa lera la daemane la polycrystalline le khomaretsoeng ka thata ho substrate ea tungsten carbide.
Kamora moo, thepa ea PDC e entsoe ka sebopeho sa lisekoere ho sebelisoa lisebelisoa tsa ho itšeha ka nepo le mochini. Lithako li entsoe ka hloko le ho belisoa ho netefatsa ts'ebetso e nepahetseng ea ho itšeha le ho phela nako e telele.
Li-cutters tsa Square PDC li fana ka melemo e mengata lits'ebetsong tsa ho cheka:
1. Mokhoa o Ntlafetseng oa ho Seha: Sebopeho sa lisekoere se fana ka sebaka se seholoanyane sa ho itšeha ha se bapisoa le libopeho tse ling, e leng se fellang ka katleho e ntlafetseng ea ho itšeha. Sena se lumella lebelo la ho cheka ka potlako, litekanyetso tse phahameng tsa ho kenella, le tlhahiso e eketsehileng.
2. Kaho e Matla le e Tšoarellang: Liseha tsa Square PDC li tsebahala ka kaho ea tsona e tiileng, e li nolofalletsang ho mamella mocheso o phahameng, likhatello le mahlaba. Ho tšoarella ha tsona ho fetolela bophelo bo atolositsoeng ba lisebelisoa, ho fokotsa tlhoko ea khafetsa ea li-cutters le ho ntlafatsa ts'ebetso e ntle ea litšenyehelo.
3. Taolo ea Chip e Sebetsang: Sebopeho sa lisekoere se thusa ho ntša li-chip ka katleho nakong ea ts'ebetso ea ho cheka. Moqapi oa sehahi o lumella ho tlosoa ka katleho ha li-cuttings tsa ho cheka, ho thibela ho koala le ho etsa bonnete ba hore mekhoa ea ho phunya e boreleli.
4. Mefuta-futa: Li-cutter tsa Square PDC ke lisebelisoa tse fapaneng tse loketseng ho cheka ka mefuta e mengata ea libopeho, ho kenyeletsa le majoe a kopantsoeng le a sa kopanngoeng. Ho feto-fetoha hona ho etsa hore ba ikamahanye le maemo a fapaneng a ho cheka le lits'ebetso.
5. Boleng bo Ntlafetseng ba Hole: Sebopeho sa lisekoere se tlatsetsa boleng bo ntlafetseng ba lesoba le ho nepahala. E thusa ho boloka masoba a otlolohileng le ho fokotsa menyetla ea ho kheloha kapa ho kheloha nakong ea ho cheka, e leng se bakang likoti tse nepahetseng le tse hokahaneng hantle.
6. Ho lumellana le Matrix le Mele ea Litšepe: Li-cutters tsa PDC tsa Square li lumellana le likotoana tsa 'mele oa matrix le tšepe, ho atolosa ho feto-fetoha ha tsona le ho sebetsa ho pholletsa le mekhoa e fapaneng ea ho cheka.
Ka kakaretso, li-cutters tsa PDC tse lisekoere ke lisebelisoa tse ntle haholo tsa ho seha ts'ebetsong ea ho cheka. Bokhoni ba bona bo matlafalitsoeng ba ho itšeha, ho tšoarella, taolo ea chip, ho feto-fetoha ha maemo, le ho tsamaellana ho ba etsa khetho e ratoang bakeng sa ho fihlela lits'ebetso tsa ho cheka tse sebetsang hantle le tse ntle ho pholletsa le mefuta e fapaneng.
