Li-Fire Mills: Lisebelisoa tse Nepahetseng bakeng sa Mechini ea CNC le ho Fetela ho Eona

Litlhaloso tsa Tekheniki tsa End Mills

Lifeme tsa ho qetela tsa Shanghai Easydrill li entsoe ka mokhoa oa ho tšoarella le ho nepahala. Likarolo tsa bohlokoa li kenyelletsa:

• Thepa:
  • Carbide: Bakeng sa ho sebetsa ka lebelo le phahameng le ho thatafala (HRC 55+).
  • Tšepe e Potlakileng (HSS): E theko e tlase bakeng sa ho sila ka kakaretso.
  • HSS e Ntlafalitsoeng ke Cobalt (HSS-E): Ho hanyetsa mocheso ho ntlafetseng bakeng sa metsoako e thata.
• Liaparo:
  • TiN (Titanium Nitride): Sekoahelo se akaretsang bakeng sa ho robeha ho fokotsehileng.
  • TiAlN (Titanium Aluminium Nitride): Ho hanyetsa mocheso o phahameng (ho fihlela ho 900°C).
  • AlCrN (Aluminium Chromium Nitride): E loketse thepa e seng ea ferrous joalo ka aluminium.
• Mefuta ea Flute:
  • 2-Flute: Ho tlosa chip hantle ka har'a thepa e bonolo (mohlala, aluminium).
  • 4-Flute: Matla a leka-lekaneng le qetello bakeng sa tšepe le litšepe tse thata.
  • Liphala tse 6+: Qetello e nepahetseng haholo ka li-alloy tsa sefofane.
• Bophara ba bophara: 1mm ho isa ho 25mm, e sebetsanang le ho sila ka lintlha tse nyane le ho sila ka boima.
• Likhutlo tsa Helix:
  • 30°–35°: Bakeng sa litšepe tse thata (mohlala, titanium).
  • 45°–55°: Bakeng sa thepa e bonolo le ho tlosa chip ka katleho.
• Mefuta ea Shank: E otlolohileng, Weldon, kapa BT/HSK bakeng sa ho tsamaisana ha mochini oa CNC.
• Litlhahiso tsa Lebelo:
  • Aluminium: 500–1,500 RPM
  • Tšepe: 200–400 RPM
  • Ts'epe e sa beng le mabali: 150–300 RPM
• Lisebelisoa tse lumellanang: Tšepe (tšepe, aluminium, titanium), polasetiki, metsoako le lehong.

Litšebeliso tsa End Mills

Li-end mill li ka sebelisoa libakeng tse fapaneng ho pholletsa le liindasteri:

1. Mechini ea CNC: Etsa likarolo tse rarahaneng bakeng sa likoloi, lifofane le lisebelisoa tsa elektroniki.
2. Ho Etsa Hlobo: Sebetsa ka ho qapa masoba a nang le dintlha tse qaqileng ka hara dibopeho tsa ente ka ditshilo tsa ho qetela tse kang bolo.
3. Lifofane: Metswako e bobebe ya mochini jwalo ka titanium le Inconel bakeng sa dikarolo tsa enjene.
4. Likoloi: Liboloko tsa enjene ea fektheri, likarolo tsa phetiso, le lisebelisoa tse ikhethileng.
5. Ho sebetsa ka lehong: Mekhabiso ea matsoho le lihokelo tsa maiketsetso tse nang le li-end filler tse khethehileng.
6. Lisebelisoa tsa Bongaka: Hlahisa disebediswa tse nepahetseng tsa ho buoa le di-implant ka thepa e tsamaellanang le mmele.

Melemo ea ho Sebelisa Li-End Mills

Lifeme tsa ho qetela li sebetsa hantle ho feta lisebelisoa tsa setso ka melemo ena:

• Ho nepahala: Finyella mamello e tiileng (± 0.01mm) bakeng sa li-geometri tse rarahaneng.
• Ho feto-fetoha ha maemo: Seha ka lehlakoreng lefe kapa lefe (le otlolohileng, le nang le radial, kapa le nang le sebopeho sa contouring).
• Bokgoni: Sekhahla se phahameng sa ho tlosa thepa (MRR) se fokotsa nako ea ho sebetsa.
• Ho tšoarella: Khabide le masela a tsoetseng pele a eketsa bophelo ba lisebelisoa ka makhetlo a 3–5.
• Qetello ea Bokaholimo: Hlahisa diqeto tse kang seipone ka ho se lokisa haholo kamora ho sebetsa.
• Ho ikamahanya le maemo: E fumaneha ka meralo e sekwere, nko e otlolohileng, le bophara ba sekhutlo bakeng sa mesebetsi e fapaneng.
