Joalo ka lisebelisoa tse nepahetseng tsa mochini, ts'ebetso le nako ea bophelo ea mechini ea ho lokisa li itšetlehile haholo ka thepa e sebelisoang. Nakong ea ts'ebetso ea ho holisa, likarolo li ba tlas'a khatello e phahameng,{1}}ho hohlana ha maqhubu a phahameng, le litlamorao tse senyang tsa pholiso. Ka hona, thepa e tlameha ho ba le boima bo phahameng, khanyetso e ntle ea ho roala, ho hanyetsa mokhathala le ho hanyetsa kutu. Sengoliloeng sena se tla shebisisa melao-motheo ea khetho ea thepa le lisebelisoa tse tloaelehileng tse sebelisoang bakeng sa likarolo tsa mochini oa honing.
1. Khetho ea Boitsebiso bakeng sa Ho Hlompha Lihlooho
Hlooho ea honing ke karolo ea mantlha ea mochini oa honing, o ikopanya ka kotloloho le workpiece. Boitsebiso ba eona bo ama ka ho toba ho nepahala le ho sebetsa hantle ha machining. Lisebelisoa tse tloaelehileng tsa honing hlooho li kenyelletsa:
Carbide (joalo ka WC-Co): E na le ho thatafala ho hoholo le ho se mamelle, ho e etsa hore e tšoanelehe-ho rohaka ka nepo, empa e na le ho tiea ho tlase 'me e tloaetse ho ba brittleness.
Ceramics (joaloka Al₂O₃ le SiC): E fana ka-mocheso o phahameng le ho bola, e etsa hore li tšoanelehe-ho holisa ka lebelo le holimo. Leha ho le joalo, li brittle ebile li hloka moralo o ntlafalitsoeng.
Litšepe tse thata (tse kang Cr12MoV le SKD11): E finyella ho thatafala ho hoholo (HRC 60+) ka ho phekola mocheso, e fana ka matla le ho hanyetsa ho apara ka theko e utloahalang le tšebeliso e pharaletseng.
2. Honing Rod le Spindle Materials
Li-honing rod le li-spindle li tlas'a meroalo e fapanyetsanang le likhohlano tse potolohang, tse hlokang matla a phahameng a mokhathala le ho satalla.
Structural alloy steel (joalo ka 40Cr le 20CrMnTi): Kamora ho halefa kapa carburizing, e fana ka matla le ho se mamelle, ho etsa hore e tšoanele maemo a mahareng-moroalo.
Stainless steel (jwalo ka 38CrMoAlA): Nitriding e etsa hore HV e thatafale 900+, e etsa hore e senyehe-e hlolehe ho bola,{3}}e hlolehe ho sebetsa,{4}}e sebetsa ka nepo le{5}ka nako e telele.
Li-alloys tse phahameng-tse kang li-alloys tsa titanium): E bobebe hape e matla-e phahameng, empa e bitsa chelete e ngata, e sebelisoa haholo mecheng e khethehileng ea{2}}e phahameng.
3. Tataiso ea Sleeve le Lisebelisoa tsa ho Beha
Sleeve ea tataiso e tiisa ho nepahala ha motsamao oa hlooho ea honing, athe ho beha ho ama botsitso ba ho potoloha. Lisebelisoa tsa bona li tlameha ho fana ka likhohlano tse tlase le khanyetso e phahameng ea ho apara:
Metsoako ea koporo (joaloka ZCuSn10Pb1): Ho itšebetsa hantle haholo-, ho loketse-matsoho a tataiso a lebelo a tlase.
Bearing steel (joaloka GCr15): High-carbon chromium steel e thata haholo (HRC 60+) ka mor'a ho tima, e sebelisoang haholo ho li-rolling bearing.
Lipolasetiki tsa boenjineri (tse kang PEEK le PTFE): Ha li khohlane-e bile li fokola{1}}ka tlase, li loketse thepa e bobebe kapa libaka tse khethehileng (joalo ka indasteri ea lik'hemik'hale).
4. Cooling System le Seal Materials
Sepholisa se sebelisoa nakong ea ho holisa, kahoo liqibi le likaroloana tse kolobisitsoeng li tlameha hore li se ke tsa rula-
Nitrile rabara (NBR): Oli-e hanyetsana le mocheso-e hananang le thempereichara, e loketse ho sebelisoa libakeng tse tloaelehileng tsa ho pholisa.
Fluorocarbon rabara (FKM): E hanana le asiti e matla le alkalis, e loketseng ho sebelisoa libakeng tse thata tsa lik'hemik'hale.
Liring tsa tšepe tse sa hloekang kapa tsa ceramic: Ha li na kutu{0}}Haholo, 'me li loketse nako e telele{1}, ts'ebetso e tsitsitseng.
5. Lintlha Tse ka Sehloohong Bakeng sa ho Khetha Lintho
Wear resistance: The honing head le spindle li tlameha ho mamella ho roala ha nako e telele-
Thermal stability: Nakong ea ho holisa{0}ka lebelo le phahameng, thepa e lokela ho qoba ho senyeha ha mocheso.
Ho sebetsa hantle ha moruo: Ha o ntse o netefatsa ts'ebetso, beha pele litšenyehelo-lisebelisoa tse sebetsang hantle.
Ts'ebetso: Thepa e lokela ho ba bonolo ho e etsa mochini, ho tšoara mocheso le ho bokana.
Qetello
Khetho ea thepa bakeng sa likarolo tsa mochini oa ho lokisa e hloka ho nahanoa ka botlalo ka maemo a ts'ebetso, litlhoko tsa ts'ebetso le litšenyehelo. Carbide, hardened steel, le alloy structural steel ke likhetho tse tloaelehileng-tse sebetsang hantle, athe lisebelisoa tse ncha joalo ka lirafshoa le polasetiki ea boenjiniere le tsona li bapala karolo ea bohlokoa lits'ebetsong tse ikhethileng. Nakong e tlang, ka tsoelopele ea mahlale a thepa, lisebelisoa tse ncha tse bobebe, tse sa khathaleng-tse hananang le ho bola{4}}li tla ntšetsa pele nts'etsopele ea theknoloji ea ho hopa.
