I-Aluminium isetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yeempawu zayo ezilula, ezihlala ixesha elide nezimelana nokugqwala. Ukusuka kwi-aerospace nakwiimoto ukuya kwi-elektroniki kunye nolwakhiwo, i-aluminium yintsimbi eguquguqukayo efuna umatshini ochanekileyo ukuvelisa iindawo ezikumgangatho ophezulu. Xa kusetyenzwa i-aluminium, ukukhetha isixhobo sokusika kudlala indima ebalulekileyo ekufezekiseni iziphumo ezifunwayo. Phakathi kwezixhobo ezahlukeneyo zokusika ezikhoyo, ii-aluminium cutting end mills zenzelwe ngokukodwa ukuhlangabezana nemingeni eyahlukileyo yomatshini we-aluminium.
Iifektri ze-aluminium ziyilwe ngeempawu ezikhethekileyo zokusika nokubumba izixhobo zokusebenza ze-aluminium ngempumelelo. Ezi fektri zenzelwe ukumelana neempawu ezikhethekileyo ze-aluminium, njengeqondo layo lokunyibilika eliphantsi, ukuthambekela kokuphuhlisa umda owakhelwe phezulu, kunye nokuthambekela kokunamathela kwizixhobo zokusika. Ngokuqonda iimfuno ezithile zomatshini we-aluminium, abavelisi baye baphuhlisa iifektri ze-aluminium ezilungiselelwe ukusika ezi zinto ngokuchanekileyo nangokufanelekileyo.
Enye yezinto ezibalulekileyo ekufuneka ziqwalaselwe xa ukhetha isixhobo sokusika i-aluminium kukwakhiwa kwezinto. Ii-end mills zentsimbi ekhawulezayo (HSS) zihlala zisetyenziselwa ukutshiza i-aluminium ngenxa yokukwazi kwazo ukumelana nobushushu obuveliswa ngexesha lenkqubo yokusika. Nangona kunjalo, kwizicelo ezifuna kakhulu, ii-end mills ze-carbide ziyathandwa ngenxa yobunzima bazo obuphezulu kunye nokumelana nobushushu. Ii-end mills ze-carbide ziyakwazi ukugcina umda wokusika obukhali kwaye zimelane nobushushu obuphezulu obuveliswa xa kutshizwa i-aluminium, nto leyo ebangela ukuba izixhobo zihlale ixesha elide kwaye zisebenze ngcono.

Ukongeza kwisakhiwo sezinto, i-geometry ye-end mill yenye into ebalulekileyo ekufuneka iqwalaselwe xa kusetyenzwa i-aluminium. Ii-aluminium end mills zine-flute designs ezithile kunye nee-helix angles ezilungiselelwe ukukhupha ii-chip kunye nokunciphisa imiphetho eyakhiweyo. I-flute geometry yezi-end mills inceda ukususa ii-chips kwindawo yokusika ngempumelelo, ithintela ukusika kwakhona kwee-chip kunye nokuqinisekisa isenzo sokusika esigudileyo. Ukongeza, i-helix angle ye-end mill idlala indima ebalulekileyo ekulawuleni ukuhamba kwee-chip kunye nokunciphisa umngcipheko wokuqokelelwa kwee-chip, okunokukhokelela ekugqityweni kakubi komphezulu kunye nokuwohloka kwezixhobo.
Ukwambathiswa okanye unyango lomphezulu wesixhobo sokusika nako kubalulekile xa ukhetha isixhobo sokusika esifanelekileyo. Iimatshini zokusika ze-aluminium zihlala zigqunywe ngezinto ezikhethekileyo ezifana ne-TiCN (titanium carbonitride) okanye i-AlTiN (aluminium titanium nitride) ukuphucula ukusebenza kwazo kunye nokuqina kwazo. Ezi zixhobo zibonelela ngokuqina okwandisiweyo, ukutyeba kunye nokumelana nobushushu, nto leyo ebalulekileyo ekwandiseni ubomi besixhobo kunye nokugcina imiphetho yokusika ibukhali xa kusenziwa i-aluminium.
Ukukhethwa kwe-aluminium end mill kuxhomekeke kwindlela ethile yokusebenza kwe-machining eyenziwayo. Kwi-rough machining, ii-end mill ezine-variable helix kunye ne-pitch designs zikhethwa ukususa izinto ngokufanelekileyo nokuthintela ukungcangcazela. Kwelinye icala, kwii-end mills ezine-geometries ezisebenza kakuhle kunye nonyango lwe-edge zisetyenziselwa ukufezekisa ukugqitywa okuphezulu komphezulu kunye nokuchaneka kobukhulu.

Ukongeza kwimiba yobugcisa, ukukhetha isixhobo sokusika esifanelekileyo se-aluminium kufuna nokuqwalaselwa kwezixhobo zomatshini kunye neeparamitha zokusika. Isantya se-spindle, isantya sokutya kunye nobunzulu bokusika zidlala indima ebalulekileyo ekwenzeni ngcono ukusebenza kwee-aluminium cutting end mills. Iiparamitha zokusika ezicetyiswayo ezibonelelwa ngumenzi wezixhobo kufuneka zilandelwe ukuqinisekisa ukukhutshwa kweetshiphusi ngokufanelekileyo, ukunciphisa ukuguguleka kwezixhobo kunye nokwandisa ubomi bezixhobo.
Xa kufikwa kwizicelo zeemilo ze-aluminium, amashishini afana ne-aerospace, iimoto, kunye ne-elektroniki axhomekeke kwezi zixhobo zokusika ukuvelisa iindawo ezinobunzima obuqinileyo kunye nomgangatho ophezulu womphezulu. Ishishini le-aerospace ngokukodwa lifuna ukwenziwa ngokuchanekileyo kwezinto ze-aluminium kwizakhiwo zeenqwelo-moya, iindawo ze-injini kunye nokuhlobisa kwangaphakathi. Iimilo ze-aluminium zidlala indima ebalulekileyo ekufezekiseni ukuchaneka okufunekayo kobukhulu kunye nokugqitywa komphezulu kwezi zicelo zibalulekileyo.
Ngamafutshane, ii-aluminium cutting end mills zizixhobo ezibalulekileyo zokulungisa ngokuchanekileyo izinto ze-aluminium kumashishini ahlukeneyo. Uyilo olukhethekileyo, ukwakheka kwezinto kunye nokufakwa kweengubo kwezi zixhobo zokulungisa zenziwe ngendlela yokuba zihlangabezane nemingeni eyahlukileyo yokusika i-aluminium, ukuqinisekisa ukususwa kweetshiphusi ngokufanelekileyo, ukunciphisa imiphetho eyakhiweyo kunye nokwandisa ubomi besixhobo. Ngokukhetha i-aluminium end mill efanelekileyo kunye nokwenza ngcono iiparameter zokusika, abavelisi banokufikelela kwiziphumo ezigqwesileyo ngokubhekiselele kubuchule bokulinganisa, ukugqitywa komphezulu kunye nemveliso xa belungisa iindawo ze-aluminium. Njengoko imfuno yezinto ze-aluminium ezikumgangatho ophezulu iqhubeka nokukhula, indima ye-aluminium cutting end mills kwi-end milling ngokuchanekileyo isabalulekile.
