Koporo le metsoako ea eona e ntse e le tse ling tsa lisebelisoa tse putsang ka ho fetisisa - 'me ka linako tse ling li le thata - ho sebelisoa mochining. Ho tsamaisa mocheso le motlakase hantle, thepa ea tlhaho ea ho loantša likokoana-hloko, le ho sebelisoa hape ka botlalo ho etsa hore li be tsa bohlokoa likarolong tsa EV, lisebelisoa tsa metsing, li-gear tse nepahetseng, le li-electrode tsa ho tjheseletsa. Empa bonolo ba tsona, tšekamelo ea ho sebelisa lithulusi ka manonyeletso, le boitšoaro ba ho thatafatsa mosebetsi li hloka mokhoa o nepahetseng.
Ka 2026, ka tlhoko ea koporo e ntseng e eketseha ka lebaka la motlakase le lisebelisoa tse nchafatsoang, litsebi tsa mechini li bona liodara tse ngata tsa li-alloy tse sebetsang hantle. Tataiso ena e akaretsa limaraka tse tloaelehileng tsa koporo tseo re sebetsang le tsona, lits'ebetso tse loketseng, melemo/liphephetso tsa bohlokoa, malebela a moralo a sebetsang, likeletso tsa lisebelisoa, le lits'ebetso tsa lefats'e la nnete.
Mekhahlelo e Tloaelehileng ea Koporo bakeng sa Mechini ea CNC
Mananeo a fapaneng a hloka di-alloy tse fapaneng. Mona ke dikereiti tseo re di bonang hangata mabenkeleng a ho sebetsa ka nepo:
- Koporo e Hloekileng (C10100/C11000): 99.9%+ bohloeki, ha e na oksijene kapa ETP. E molemo ka ho fetisisa bakeng sa ho tsamaisa motlakase ka bongata (li-busbars, li-heat sinks).
- Koporo (C36000, C26000): E ratoa haholo ke mochini o lokolohileng ka ho roba chip hantle. E loketse ho kenngoa, li-valve, li-gear.
- Boronse ea Aluminium (C95400, C95500): Matla a phahameng + ho hanyetsa mafome a metsi a leoatle ka tsela e ikhethang. E loketse li-propeller tsa leoatleng, li-bushing.
- Boronse ea Tin (C90300, C90700): E hanyetsa ho tsofala hantle le khohlano e tlase. E tloaelehileng bakeng sa li-bearing le li-gear tse boima.
- Phosphor Bronze (C51000, C54400): Ho ba matla haholo ha springing le ho hanyetsa mokhathala. E tloaelehile lihokelong le lispringing.
- Koporo ea Chromium Zirconium (C18150/C18200): Pula e thatafalitsoe bakeng sa matla a phahameng + 80-90% IACS conductivity. E laola li-electrode tsa ho tjheseletsa tse hanyetsanang le likarolo tsa enjene ea EV.
-
Keletso ea Khetho ea Sehlopha se Potlakileng: Bakeng sa likarolo tsa motlakase → khetha koporo e hloekileng kapa CuCrZr. Bakeng sa libaka tse sekametseng ho senyeha → khetha boronse ea aluminium. Bakeng sa ho sebetsa ka bongata habonolo → sebelisa koporo.
Mekhoa e Loketseng ea ho Sebetsa ka Mechini bakeng sa Koporo
Mochini o moholo oa limaraka tsa koporo o sebetsa hantle lisebelisoa tse tloaelehileng tsa CNC:
- Ho Siloa ha CNC: E loketse li-geometri tse rarahaneng, lipokotho, le likarolo tse 3-5 tsa axis.
- Ho Fetola ha CNC: E loketse likarolo tse chitja tse kang li-bushing, li-fittings le li-shaft.
- Ho tjheka le ho penya: Pompo ea koporo le phosphor ka mokhoa o hloekileng; sebelisa ho phunya masoba a tebileng ka koporo e hloekileng.
- Lathe ea Mofuta oa Switzerland: E ntle haholo bakeng sa li-pin le lihokelo tse nyane tse nepahetseng haholo.
- EDM (haeba ho hlokahala): Ha e hlokehe hangata empa e na le thuso bakeng sa likarolo tsa CuCrZr tse thatafalitsoeng.

Melemo ea ho Etsa Li-alloy tsa Koporo ka Machining
- Ho tsamaisa mocheso ka tsela e phahameng → ho qhala mocheso ka potlako, ho fokotsa ho tsofala ha disebediswa.
- Thepa e ntle ea motlakase → ea bohlokoa bakeng sa lihokelo le li-electrode.
- Bokaholimo ba tlhaho ba ho loantša likokoana-hloko → bo loketse ho sebelisoa ha lijo le likarolo tsa bongaka.
- Ho sebelisoa hape ka botlalo → ho tsamaisana le litaelo tsa botsitso tsa 2026.
- Liphetho tse ntle → koporo le polish ea boronse ho fihlela e benya haholo.
Liphephetso le Litharollo tse Sebetsang
Ho ba bonolo ha koporo ho baka mathata a tloaelehileng — ke kamoo re a sebetsanang le ona kateng:
- Li-chips tse bonolo le bohale bo hahiloeng— Sebelisa lisebelisoa tse bohale tse thusang ho tlosa litšila tse kotsi le sesebelisoa se ngata sa ho pholisa (emulsion kapa oli).
- Ho thatafatsa mosebetsi— Nka litsela tse bobebe (botebo ba 0.1-0.5 mm) 'me u qobe ho lula.
- Sebopeho sa Burr— Mechini ea koporo ha e na mashala; koporo e hloekileng e hloka ho tlosoa mashala kapa ho siloa ha ho hloa.
- Katoloso ea mocheso— Sesebediswa ka hloko mme o sebedise sephodisang metsi ho laola boholo.
Keletso ea Setsebi: Bakeng sa koporo e hloekileng, lisebelisoa tsa taemane ea polycrystalline (PCD) li nka nako e telele ka makhetlo a 10 ho feta carbide.

Mehopolo le Malebela a Moralo
- Mamello: ±0.01 mm e ka fihlelleha hodima koporo/CuCrZr; koporo e hlwekileng e ka hloka ±0.02 mm ka lebaka la bonolo.
- Botenya ba lebota: Bonyane 0.5-1 mm ho qoba ho kheloha.
- Li-radii le Li-fillet: Kenya mahlaseli a mangata (bonyane 0.5 mm) ho fokotsa khatello ea maikutlo le ho ntlafatsa bophelo ba sesebelisoa.
- Qetello ea Bokaholimo: Ra 0.4 µm ke e tloaelehileng e nang le khabide e bentšitsoeng; liphetho tsa seipone lia khoneha ka koporo.
- Kalafo ea Mocheso: CuCrZr e hloka botsofali kamora ho tsofala bakeng sa ho tiea ka botlalo — rera ka ho loketseng.
Litlhahiso tsa Lisebelisoa le Liparamente
- Lisebelisoa tsa Sesebelisoa: Carbide e sa koaheloang kapa e koahetsoeng ka daemane bakeng sa boholo ba eona; PCD bakeng sa mosebetsi oa bolumo ba koporo e hloekileng.
- Mabelo le Dijo (mohlala bakeng sa koporo ya C36000, sile ya pheletso ya 10 mm):
- Sekotwana sa ho tjhesa: 8,000-12,000 RPM
- Fepa: 1,000-2,000 mm/motsotso
- Botebo ba sehiloeng: 0.5-2 mm axial
- Sehatsetsi: Sebelisa kamehla — e thibela ho teneha 'me e ntlafatsa qetello.
Likopo tsa Lefatše la Sebele
- Koporo → li-gear tse nepahetseng, 'mele ea li-valve, lisebelisoa tsa mekhabiso.
- Boronse ea Aluminium → lihlahla tsa leoatleng, li-impeller tsa pompo.
- Boronse ea Tin → Likere tsa seboko, libere tse boima.
- Phosphor Bronze → dikgokelo tsa selemo sa motlakase.
- Koporo e Hloekileng → li-exchange tsa mocheso, li-busbars.
- CuCrZr → li-electrode tsa ho tjheseletsa matheba, mekoallo ea rotor ea EV.
Lintlha tsa Litšenyehelo le Botsitso ka 2026
Litheko tsa thepa lia fetoha (koporo e hloekileng ~$11-13k/ton), empa koporo e ntse e le theko e tlase haholo. Litefiso tsa ho sebelisa hape hona joale li feta 50% mabenkeleng a mangata, li fokotsa litšenyehelo le khabone e feteletseng. Lebella phepelo e thata bakeng sa CuCrZr ka lebaka la tlhoko ea EV.
Mehopolo ea ho Qetela
Ho sebetsa ka koporo ho putsa ho hlophisoa ka hloko le khetho e nepahetseng ea boleng. Ka malebela a kaholimo, u tla lula u hlahisa likarolo tsa boleng bo holimo, tse sebetsang tse fihlelang esita le litlhaloso tse thata ka ho fetisisa.
Na u se u loketse ho phelisa moralo oa hau? Hlahloba mefuta eohle ea rona ea li-alloy tsa koporo (koporo, boronse ea aluminium, boronse ea tin, boronse ea phosphor, koporo e hloekileng, le CuCrZr) lethathamong la rona la lihlahisoa tsa morao-rao, kapa ikopanye le sehlopha sa rona sa boenjiniere bakeng sa litheko tse ikhethileng tsa ho sebetsa le tšehetso ea tekheniki.
