U ka ntlafatsa machinability ea aluminium joang?

Aluminium ke e 'ngoe ea litšepe tse sebetsang ka ho fetisisa tseo u ka li fumanang.U ka ntlafatsa machinability ea eona ka metallurgy - tšepe ka boeona.Mona ke litsela tse ling tsa ho ntlafatsa machina a aluminium.

Li-Machinists li ka kopana le mefuta le liphephetso tse ngata hoo ho ka bang thata ho bolela esale pele.E 'ngoe ke boemo ba thepa, le litšobotsi tsa eona tsa' mele.Ka aluminium, ke bua ka alloying elements, microstructure, hardness, yield strength, tensile strength, le work hardness.Har'a lintho tse ling.

U ka sheba sena ka mokhoa o ts'oanang le baapehi ba ntseng ba lokisa lijo, hore lintho tse bonahalang tse tala.Ho ba le lisebelisoa tse ngata tse tala ho tla ntlafatsa machinability ea aluminium mme ka hona sehlahisoa sa ho qetela.

Mabenkele a mochini a ka thusa ho ntlafatsa machane a aluminium

“Gummy” ke lentsoe le akaretsang le sebelisoang hangata le ka fetisang meelelo e fapaneng ho latela hore na u bua le mang ...Ho hlwaya bothata bo itseng ba machining ke sebaka sa pele sa ho qala leetong la ho fumana tharollo e molemohali.

Ntle le li-alloys tse fapaneng kapa khalefo, ho na le mekhoa e meng ea ho ntlafatsa machinability ea aluminium - lintho tseo u ka li amang - ho qala ka mabenkele a mochini a sehang lisebelisoa, mafura le ts'ebetso ea machining.

Rea tseba hore aluminium e ka etsoa ka katleho ka mefuta e mengata ea lisebelisoa tsa ho itšeha;lisebelisoa tsa tšepe, tšepe ea lebelo le phahameng, li-carbides tse entsoeng ka samente, liaparo tsa daemane.Mefuta e meng ea liphahlo tsa Physical Vapor Deposition (PVD) le lisebelisoa tsa ho itšeha tse thehiloeng ka ceramic ha li tšoanelehe bakeng sa ho seha aluminium ka lebaka la ho kopana ha lik'hemik'hale bakeng sa aluminium kapa ho roala ho thata ho ka fella ka ho tlama ha aluminium holim'a sesebelisoa sa ho itšeha.

Ho boetse ho na le mefuta e mengata ea metsi a sehang a fumanehang, ho tloha ho metsi a qhibilihang ho ea ho a thehiloeng ka oli, ho kenyelletsa le maro a itseng a maiketsetso a ka bang le li-additives tse ling tse senyang aluminium.

Lintlha tse ling tsa ho ntlafatsa machinability ea aluminium

Hang ha lisebelisoa tse nepahetseng le maro a sehang li se li khethiloe, lintlha tse ling tsa bohlokoa ke tsena tse ka kenyang letsoho ntlafatsong ea machina:

• Lisebelisoa le lisebelisoa li tlameha ho ba tse thata
• Lisebelisoa li lokela ho ba le moeli o motle oa fatše ho fokotsa ho haha
• Lithako tse sehang li lokela ho lula li le bohale ka linako tsohle
• Li-chips li tlameha ho lebisoa hole le sekoahelo sa mosebetsi kapa li robehe ka seqhetso ho thibela tšenyo ea karolo kapa sesebelisoa
• Tlhahiso e ka ntlafatsoa ka ho eketsa lebelo ha ho ntse ho bolokoa litekanyetso tsa lijo le ho khaola botebong bo itekanetseng.Aluminium ka kakaretso e rata ho khaoloa ka lebelo le holimo
• Likhatello tse feteletseng tsa ho itšeha li lokela ho qojoa ntle le haeba workpiece e tšehetsoa ka ho lekaneng
• Litefiso tse tlase tsa lijo li lokela ho sebelisoa likarolong tse tšesaane tse nang le marako
• Li-angles tsa rake tse khothalelitsoeng li lokela ho sebelisoa ho fokotsa matla a ho itšeha, ka hona ho hlahisa li-chips tse tšesaane le ho fokotsa ho haha ​​​​metšepe.Boholo ba baetsi ba lisebelisoa hona joale ba fana ka lisebelisoa tse etselitsoeng ho seha aluminium ka li-angles tsa rake
• Li-drill tsa phepelo e pholileng, geometry ea lekolilo
• Sistimi ea phepelo e pholisang e nang le khatello e phahameng

Ho ipapisitse le mofuta oa lisebelisoa tsa machining (litsi tsa machining tsa CNC, metjhini e mengata ea li-spindle screw) e ka sebetsang holim'a mefuta e mengata ea li-RPM, lisebelisoa tse fapaneng tsa ho itšeha, lisebelisoa le lisebelisoa tsa mochini li tla hloka ho tsotelloa ha ho etsoa machining aluminium.

Keletso ea ka ke hore u kenye lisebelisoa tsa hau tsa ho itšeha, mafura le li-extrusion bafani ba amehang ho u thusa ka likhothaletso tse qaqileng.Qetellong ea letsatsi, tšehetso ena ea tekheniki e tla u bolokela nako le chelete.
