I-Aluminium isetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezingasindi, eziqinile futhi ezimelana nokugqwala. Kusukela ku-aerospace kanye nezimoto kuya ezintweni zikagesi nezokwakha, i-aluminium iyinsimbi eguquguqukayo edinga ukwenziwa kwemishini enembile ukuze kukhiqizwe izingxenye zekhwalithi ephezulu. Lapho ukhiqiza i-aluminium, ukukhetha ithuluzi lokusika kudlala indima ebalulekile ekuzuzeni imiphumela oyifunayo. Phakathi kwamathuluzi okusika ahlukahlukene atholakalayo, izigayo zokusika ze-aluminium zenzelwe ngokukhethekile ukuhlangabezana nezinselele eziyingqayizivele ze-aluminium machining.
Izigayo zokuphela kwe-aluminium ziklanywe ngezici ezikhethekile ukuze zisike futhi zilolonge izinto zokusebenza ze-aluminium. Lezi zigayo ziklanyelwe ukumelana nezakhiwo ezihlukile ze-aluminium, njengendawo yayo encibilikayo ephansi, ukuthambekela kokuthuthukisa unqenqema olwakhiwe, kanye nokuthambekela kokunamathela kumathuluzi okusika. Ngokuqonda izidingo ezithile zomshini we-aluminium, abakhiqizi benze izigayo zokugcina ezilungiselelwe ukusika le nto ngokunembile nangempumelelo.
Okunye okucatshangelwayo okubalulekile lapho ukhetha isigayo sokusika i-aluminium ukwakheka kwezinto. Izigayo zokugcina zensimbi enesivinini esikhulu (HSS) zivame ukusetshenziselwa umshini we-aluminium ngenxa yekhono lazo lokumelana nokushisa okukhiqizwa phakathi nenqubo yokusika. Kodwa-ke, ngezicelo ezidinga kakhulu, izigayo zokugcina ze-carbide zikhethwa ngenxa yokuqina kwazo okuphezulu nokumelana nokushisa. Izigayo ze-Carbide ziyakwazi ukugcina umkhawulo obukhali futhi zimelane nezinga lokushisa eliphezulu elikhiqizwa lapho kwenziwa i-aluminium, okuholela ekuphileni kwamathuluzi okude nokusebenza okuthuthukisiwe.

Ngokungeziwe ekwakhiweni kwezinto ezibonakalayo, i-end mill geometry ingenye into ebalulekile okufanele icatshangelwe lapho kwenziwa i-aluminium. Izigayo zokuphela kwe-aluminium zinemiklamo eqondile yomtshingo kanye nama-engeli e-helix alungiselelwe ukuphuma kwe-chip kanye nokunciphisa imiphetho eyakhelwe phezulu. I-geometry yomtshingo yalezi zigayo zokugcina isiza ukususa ngempumelelo ama-chip endaweni yokusika, ukuvimbela ukusika kabusha kwe-chip nokuqinisekisa isenzo sokusika esibushelelezi. Ngaphezu kwalokho, i-engeli ye-helix yesigayo sokuphela idlala indima ebalulekile ekulawuleni ukugeleza kwe-chip nokunciphisa ubungozi bokuqoqwa kwe-chip, okungaholela ekuqedweni okungalungile kwendawo kanye nokugqoka kwamathuluzi.
Ukwemboza noma ukwelashwa kwendawo yethuluzi lokusika nakho kuwukucatshangelwa okuyinhloko lapho ukhetha umshini wokuphela we-aluminium ofanele. Izigayo zokusika ze-Aluminium zivame ukumbozwa ngezingubo ezikhethekile ezifana ne-TiCN (titanium carbonitride) noma i-AlTiN (i-aluminium titanium nitride) ukuthuthukisa ukusebenza kwazo nokuqina. Lezi zimbobo zinikeza ubulukhuni obuningi, ukuthambisa kanye nokumelana nokushisa, okubalulekile ekwandiseni ukuphila kwamathuluzi nokugcina imiphetho yokusika ibukhali lapho kwenziwa i-aluminium.
Ukukhethwa komshini wokuphela kwe-aluminium nakho kuncike ekusebenzeni komshini othile owenziwayo. Ngomshini onzima, izigayo zokuphela ezine-helix eziguquguqukayo kanye nemiklamo ye-pitch zikhethwa ukuze zisuse izinto ezibonakalayo kahle futhi zivikele ukudlidliza. Ngokuqedela imisebenzi, ngakolunye uhlangothi, izigayo zokugcina ezinamajiyometri asebenza kahle kanye nokwelashwa onqenqemeni zisetshenziselwa ukufeza ukuphela okuphezulu nokunemba kobukhulu.

Ngaphezu kwezici zobuchwepheshe, ukukhetha isigayo sokuphela kwe-aluminium esifanele futhi kudinga ukucatshangelwa kwethuluzi lomshini kanye nemingcele yokusika. Ijubane lokuphotha, izinga lokuphakelayo nokujula kokusikwa kudlala indima ebalulekile ekuthuthukiseni ukusebenza kwezigayo zokusika ze-aluminium. Imingcele yokusika enconyiwe ehlinzekwe umenzi wamathuluzi kufanele ilandelwe ukuze kuqinisekiswe ukukhishwa okuphumelelayo kwe-chip, ukunciphisa ukuguga kwamathuluzi nokwelula impilo yamathuluzi.
Uma kuziwa ekusetshenzisweni komshini wokuphela kwe-aluminium, izimboni ezifana ne-aerospace, izimoto, kanye ne-electronics zithembele kulawa mathuluzi okusika ukukhiqiza izingxenye ezinokubekezelelana okuqinile kanye nekhwalithi ephezulu yendawo. Imboni ye-aerospace ikakhulukazi idinga ukunemba kwemishini ye-aluminium yezakhiwo zezindiza, izingxenye zenjini kanye nokunqunywa kwangaphakathi. Izigayo zokuphela kwe-aluminium zidlala indima ebalulekile ekuzuzeni ukunemba kobukhulu obudingekayo kanye nokuqedwa kwendawo kulezi zinhlelo zokusebenza ezibalulekile.
Ukufingqa, izigayo zokusika ze-aluminium zingamathuluzi abalulekile wokwenza imishini ye-aluminium ngokunemba ezimbonini ezahlukahlukene. Idizayini eyisipesheli, ukwakheka kwezinto ezibonakalayo kanye nama-coatings alezi zigayo zokugcina zenzelwe ukuhlangabezana nezinselele eziyingqayizivele zokusika i-aluminium, ukuqinisekisa ukukhishwa okuphumelelayo kwama-chip, ukunciphisa imiphetho eyakhelwe phezulu kanye nokwelula impilo yamathuluzi. Ngokukhetha isigayo sokuphela kwe-aluminium esifanele kanye nokuthuthukisa imingcele yokusika, abakhiqizi bangathola imiphumela emihle kakhulu ngokunemba kwe-dimensional, ukuphela kwendawo kanye nokukhiqiza lapho benza izingxenye ze-aluminium. Njengoba isidingo sezingxenye ze-aluminium ezisezingeni eliphezulu siqhubeka sikhula, indima yezigayo zokusika i-aluminium ekugayeni okunembayo isalokhu ibalulekile.
