Gani cewa Apple ya sa aluminum mai tsawo unibody a iPhone 17 Pro kuma duba cewa CNC machining ya ke ƙarin aiki da fadin gwaji
Gabatarwa
Kada Apple ya nuna unibody design na aluminum mai tsawo na iPhone 17 Pro a Fall 2025 event, ilumin spotlight ya dawo maimakon sabon abubuwa a cikin tsarin wasan ƙirƙira. A matsayin mai amfani da CNC zaƙiyyar tsarin aikawa da tattarar tsinkin abin cin hadawa muna duba wannan tsarin mai zuwa - daga ma'ana da tsarin aikawa zuwa aikace-aikacen - don nuna cewa yaya ya ke nuna standadin tattarar mai yawa.
Menene Aluminum Unibody mai Tsawon Tsafi?
Tsawon tsafi shine tsarin da ke cikin aluminum alloys suna kan digiri mai girma a tsawon zerrin, ta ba da abin da ke ƙarƙashin da karkashin a kauye yaya. Bayan hanyar gudun karamin abubuwa biyu, wannan hanyar ya samar da abun ƙarƙashi na ƙarƙashin yaya, wanda ke canzawa tsirin da abubuwan metal suke hadawa.
Don aluminum alloy 7075, range na typical na tsawon zerrin shine 370–480°C. A cikin wannan range, ƙarƙashin na abu ya yi daman kuma rashin karkashi ya yi daman, ta hanyar da alloy ya iya cire sauran cavin mold.
Zanen na Apple a cikin wannan tsarin shine mai shawara:
Bayan zerrin, madaida'in tsangewa ta dawo zuwa 300–400 MPa tare da ƙara ƙaddar da ke cikin 10–20%, wandojin alaƙa a kan tama da tsuntsaye.
A cikin ginewa mai ƙasa yin hagga na karkashin ƙasa wanda aka samu a cikin wasanni masu alaƙa, wanda ya ƙara ƙarfi da hakika 40% , kuma yin farawa da ƙarin cikin ƙasa don batiri mai girma ba tare da nufin nisa na ƙasa.
Tsarin ƙara kafi vs. Wasanni Tsarin
Don fahimtar alaƙa, mu shirya tsarin ƙara kafi da tsarin ƙara sanyi da kuma tsarin ƙara tushen.
Kira Kankara da Kira Sanyaya
Kira sanyaya a tsawon zerrin ya yi wajen ƙima da kankara (400–500 MPa+), amma kusan kankara, ya zin gaskiya daban.
Kira kankara ta hada da ƙima na zerrin ya sa bututu gudun gwiwa, ta ba da izumi mai girma da ƙwayoyin girma - mafi kyau don samfurin smartphone wanda ya kamata ya sakawa kankara da girma.
Kira Kankara da Kira Jimlarwa
Kira jimlarwa yana naka gwiwan gishin a cikin takarda ta hanyar taka leda. Ta ba da inganci mai girma amma ta yi karuwa da alalasun gandu.
Kira kankara ta hada da gwiwan gishin, ta sa gishin gwiwa ta girma da ta hada da gwiwan ba tare da alalasa. Mawar gwiwa ta tafi matakan ƙwayar gishin gwiwa ta jimlarwa.
Tsarin Kankara Kankara na Aluminum
Tsarin yana ƙayyade guzancewar zerrin, tsarin yin aiki, da kuma gudun CNC ta hanyar shidda babban tsarin:
1. Tsara Na Gudunƙar Ayyuka
Aluminum Billets mai tara da 7075 mai ƙarin zuwa → testing na composition → homogenization annealing don kawar gaskiya.
2. Takaici Na Takaici
An takaici a cikin atmosfe mai inert don 420–480°C, tare da zure mai takaici ≤5°C/min don inza samin takaici ko kankanta.
3. Die Forging
An koma zuwa a 5,000–15,000 kN mesin ƙirƙira, matsin jiki ɗin a wani ƙwallon – sannan kuma ginya da ƙofar kwayo – a wani ƙwallon.
4. Rawar Gadiya
Rawar a 480°C → gado quench
Artificial aging a 120–180°C → Tsayi ya ƙare da ~30%, tare da tattara tare da tattara.
5. CNC Tama da Ma'ali
Five-axis CNC milling ta ƙawariyan saitin aiki (ports, button slots, connectors). Tolerance ana sarrafa shi a cikin ±0.02 mm.
6. Rawar Surface & Tattauna
Anodizing ko sandblasting don tsayawa.
3D scanning + ultrasonic testing ta tuna 0.1 mm ƙimar gani na ƙima a cikin saitin da suka shafi.
Takaddun Sauran da Aikacewa
1. Tushen Aiki
Farko na gudun kwalliya yana ƙarin kusurwa. Daga titanium housings, iPhone 17 Pro’s aluminum frame ya sami 20% karin tafiyar kari da ƙarin ƙima ta 15%.
2. Tsarin Zafiya
Aluminum zai karuwa da kekere na zafiya shine kamar 20–30 karatun titanium. Dangane da tsarin zafiya ta vapor chamber, wannan zai ba da izinin A19 Pro chip don saman gwiwon aiki na uku.
3. Rarrabuwa a Nukarin Bayanin
Tukar ta ke wuya da saukewa a ninka, ba shi daidaitaccen tari daidaita masu kamera masu 8x optical zoom kamar yadda aka samar da nishidi mai gaban taka.
Bayan elektronik din mali, alaminiyar aluminum mai zafi ya har wa yayin:
Electric Vehicles (EVs): Matsayi na gaban jiki ya kara masa 30%
Aerospace: Alloy 7075 mai tsaba ake amfani dashi a cikin yin hanyar gudun kasa da sauran abubuwa da ke sauyawa.
Sudan: Turanci tare da na'urar gudunauka
IPhone 17 Pro’s bodya na aluminum mai tsaba ba hanya ce kawai ne mai girma–yana nufin canzawa a tsari na gudunauka a zaman larabci. Ta hanyar wasu al’umma na abubuwa, tsaba da alhakin girma, da karkashin CNC mai zurfi, Apple ya saita alaƙa sabuwar da ke nuna kewayar tsakanin tsini, karaƙara, da zurfina a yin tsari.
Daga tattara kama da tsofain ƙima zuwa tattara tsarin jiki, wannan tsarin ya nuna yadda abubuwan inganci na iya fitar da saƙoƙkin da zaɓin gani. A waje daga smartphone, tsarin aluminum mai tsaba yana gudunauka ta yau da kullun ingancin gudun ciwo, ingancin makaranta, da sauran abubuwan masu amfani na zamani , wanda ya nufi cewa ingancin a yau dake tsinkaya akan kibata iya amfani da saƙoƙkin da zaɓin gani.
