I-Aluminiyam isetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yobunzima bayo, ehlala ixesha elide kunye nepropathi ekwazi ukumelana nomhlwa. Ukusuka kwi-aerospace kunye nemoto ukuya kwi-electronics kunye nokwakhiwa, i-aluminiyam yintsimbi eguquguqukayo efuna umatshini ochanekileyo ukuvelisa iindawo ezikumgangatho ophezulu. Xa umatshini we-aluminium, ukhetho lwesixhobo sokusika ludlala indima ebalulekileyo ekufezekiseni iziphumo ezifunwayo. Phakathi kwezixhobo ezahlukeneyo zokusika ezikhoyo, i-aluminium yokusika i-mills yokuphela kwenzelwe ngokukodwa ukuhlangabezana nemingeni ekhethekileyo ye-aluminium machining.
Izixhobo zokugqibela ze-aluminiyam ziyilwe ngeempawu ezikhethekileyo zokusika ngokufanelekileyo kunye nokubumba izixhobo zokusebenza ze-aluminium. Ezi zixhobo zokugqibela ziyilelwe ukuba zimelane neempawu ezikhethekileyo ze-aluminiyam, njengendawo ephantsi yokunyibilika kwayo, ukuthambekela ekuphuhliseni i-edge eyakhiweyo, kunye notyekelo lokunamathela kwizixhobo zokusika. Ngokuqonda iimfuno ezithile ze-aluminium yomatshini, abavelisi baye baphuhlisa ii-mills zokugqibela ezilungiselelwe ukusika le nto ngokuchanekileyo nangempumelelo.
Enye yezinto eziphambili zokuqwalaselwa xa ukhetha i-mill end yokusika i-aluminium kukubunjwa kwezinto. I-high-speed steel (HSS) i-mill end mills isoloko isetyenziselwa umatshini we-aluminium ngenxa yokukwazi ukujamelana nokushisa okwenziwa ngexesha lokusika. Nangona kunjalo, kwizicelo ezifunwa kakhulu, ii-carbide end Mills zikhethwa ngenxa yobunzima bazo obuphezulu kunye nokumelana nobushushu. Izixhobo zokugqibela zeCarbide ziyakwazi ukugcina umgca wokusika obukhali kunye nokumelana nokushisa okuphezulu okwenziwe xa kusenziwa i-aluminium, okubangelwa ubomi obude besixhobo kunye nokusebenza okuphuculweyo.

Ukongeza ekubunjweni kwezinto eziphathekayo, i-geometry yokuphela kwe-mill yenye into ebalulekileyo ekufuneka iqwalaselwe xa usenza i-aluminium. I-aluminiyam yokuphelisa i-aluminiyam inoyilo oluthile lwefluti kunye nee-engile ze-helix ezilungiselelwe ukukhutshwa kwe-chip kunye nokunciphisa imiphetho eyakhiweyo. I-geometry ye-flute yale mibhobho yokuphela inceda ngokufanelekileyo ukususa ii-chips kwindawo yokusika, ukuthintela ukusika kwakhona kwe-chip kunye nokuqinisekisa isenzo sokusika. Ukongezelela, i-angle ye-helix ye-end mill idlala indima ebalulekileyo ekulawuleni ukuhamba kwe-chip kunye nokunciphisa umngcipheko wokuqokelelwa kwe-chip, oku kunokukhokelela ekugqityweni okungahambi kakuhle kunye nokugqoka izixhobo.
Ukugquma okanye ukunyangwa kwendawo yesixhobo sokusika kwakhona kuyingqwalasela ephambili xa ukhetha i-aluminium yokuphela kwe-mill efanelekileyo. I-aluminium yokusika i-mills ivame ukugqunywa ngeengubo ezikhethekileyo ezifana ne-TiCN (titanium carbonitride) okanye i-AlTiN (i-aluminium titanium nitride) ukuphucula ukusebenza kwabo kunye nokuqina. Ezi zogquma zibonelela ngobulukhuni obuninzi, ukuthambisa kunye nokuxhathisa ubushushu, ezibaluleke kakhulu ekwandiseni ubomi besixhobo kunye nokugcina imiphetho yokusika ibukhali xa kusetyenzwa ialuminiyam.
Ukukhetha i-aluminiyam yokusila kuxhomekeke kumatshini othile owenziweyo. Ukwenziwa komatshini orhabaxa, ii-mill end ezine-helix eguquguqukayo kunye noyilo lwepitch zikhethwa ukuba zisuse izinto ngokufanelekileyo kwaye zithintele ukungcangcazela. Ukugqibezela imisebenzi, kwelinye icala, ii-mills zokugqibela ezinejometri ezisebenza kakhulu kunye nonyango lomphetho zisetyenziselwa ukufezekisa ukugqiba okuphezulu komphezulu kunye nokuchaneka komda.

Ukongeza kwimiba yobugcisa, ukukhetha i-aluminium yokuphela kwe-mill efanelekileyo kufuna ukuqwalaselwa kwesixhobo somatshini kunye neeparitha zokusika. Isantya se-spindle, ireyithi yokutya kunye nobunzulu bokusikwa kudlala indima ebalulekileyo ekuphuculeni ukusebenza kwe-aluminiyam yokusika isiphelo somatshini. Iiparamitha zokusika ezicetyiswayo ezibonelelwa ngumenzi wesixhobo kufuneka zilandelwe ukuqinisekisa ukukhutshwa kwetshiphu okusebenzayo, ukunciphisa ukunxiba kwesixhobo kunye nokwandisa ubomi besixhobo.
Xa kufikwa kwizicelo zokuphela kwe-aluminium, amashishini afana ne-aerospace, iimoto, kunye ne-elektroniki zixhomekeke kwezi zixhobo zokusika ukuvelisa iinxalenye ezinokunyamezelana okuqinileyo kunye nomgangatho ophezulu womphezulu. Ishishini le-aerospace ingakumbi lifuna ukuchaneka kwezixhobo ze-aluminiyam kwizakhiwo zenqwelomoya, iinxalenye ze-injini kunye ne-interior trim. Izixhobo zokuphelisa i-aluminiyam zidlala indima ebalulekileyo ekufezekiseni ukuchaneka okufunekayo kobukhulu kunye nokugqitywa komphezulu kwezi zicelo zibalulekileyo.
Ukushwankathela, i-aluminiyam yokusika ii-mill end zizixhobo eziyimfuneko zokwenza izinto ezichanekileyo ze-aluminium kumashishini ahlukeneyo. Uyilo olukhethekileyo, ukwakheka kwemathiriyeli kunye nokwaleka kwezi zixhobo zokusila zilungiselelwe ukuhlangabezana nemingeni eyodwa yokusika ialuminiyam, ukuqinisekisa ukukhutshwa kwetshiphu okusebenzayo, ukunciphisa imiphetho eyakhiweyo kunye nokwandisa ubomi besixhobo. Ngokukhetha i-aluminium yokuphela kwe-mill efanelekileyo kunye nokwandisa iiparitha zokusika, abavelisi banokufikelela kwiziphumo ezigqwesileyo ngokuchaneka komgangatho, ukugqitywa komphezulu kunye nemveliso xa besenza iinxalenye ze-aluminium. Njengoko imfuno yamacandelo e-aluminium ekumgangatho ophezulu iqhubeka nokukhula, indima ye-aluminiyam yokusika i-mills ekupheleni komatshini ochanekileyo ihlala iyimfuneko.
