Umshini we-CNC we-Electronics:
Ukukhiqiza Ngokunembile Esikhathini Sedijithali
Imboni ye-elekthronikhi iyaphila futhi ife ngenxa ye-miniaturization, ukusebenza kahle kokushisa, kanye nokuthembeka okuphelele. Kusukela ku-chassis ye-aluminium ye-smartphone kuya ekushiseni kwethusi ensikeni yeseva ye-3U VPX, cishe wonke amadivayisi kagesi ancike ezingxenyeni ezaqala ukuphila njengensimbi eluhlaza emshinini we-CNC. Umshini wokulungisa we-Computer Numerical Control (CNC) uye waba umgogodla wokukhiqizwa kwezingxenye zensimbi ngokunemba okuphezulu kuma-elekthronikhi abathengi, ezokuxhumana, kuma-avionics asezindiza, kumadivayisi ezokwelapha, kanye nokubala okuphezulu.
Ngokungafani nokuphrinta kwe-3D noma ukuphonswa nge-die, imishini ye-CNC inikeza ukubekezelelana kwezinga le-micron, ukuqedwa kobuso obuhle kakhulu, kanye nekhono lokusebenza nama-alloy aqondile adingwa yi-electronics—i-aluminium 6061, ithusi elingenawo umoya-mpilo i-C10100, i-magnesium AZ91D, ithusi le-tellurium C14500, ngisho nezinto ezingavamile ezifana ne-molybdenum ne-Kovar. Lesi sihloko sihlola ukuthi kungani i-CNC ihlala ibalulekile kuma-electronics, yiziphi izinto ezibusayo, izinselele zokuklama kanye nomshini ezihlukile, amasu anamuhla okusebenzisa amathuluzi nokuhlela, izidingo zokuqeda ubuso, kanye nezitayela ezintsha ezizobumba iminyaka eyishumi ezayo.
Kungani Abakhiqizi Bezinto Zikagesi Besakhetha Imishini Ye-CNC
Ngisho nasenkathini yokunyathelisa okuthuthukisiwe kwe-3D, ukubumba nge-injection yensimbi (i-MIM), kanye nokuphonswa nge-die, ukukhanda nge-CNC kusalokhu kuyinqubo evelele yokukhiqiza izingxenye ze-elekthronikhi ezisebenza kahle kakhulu. Kusukela kuma-heat spreaders e-smartphone kuya kuma-cold plate e-AI server kanye nezihlangu ze-RF ze-base-station ze-5G, ukukhanda nge-precision subtractive kuyaqhubeka nokuba nezinzuzo ezibalulekile ubuchwepheshe bokwengeza nokwakha obungakanqotshwa.
1. Ukunemba Okungalingani kanye Nokubekezelelana Okuqinile
Umkhuba wokwenza izinto zibe zincane kuma-elekthronikhi uqhubekisele phambili izidingo zobukhulu ebangeni le-micrometer yedijithi eyodwa. Amaphakheji e-semiconductor anamuhla (ama-CoWoS-S, i-EMIB, ama-3D-IC stacks), izingxenye ze-RF ezivame kakhulu, kanye nama-photonic interconnect avame ukucacisa ukubekezelelana okungu-±5 μm noma ngisho no-±2 μm ezicini ezibalulekile.
Imishini yokugaya ye-CNC kuphela—ikakhulukazi izikhungo zokugaya ze-5-axis kanye ne-Swiss-type lathes ezihlonyiswe nge-thermal compensation, i-in-process probing, kanye ne-sub-micron tooling—engafinyelela ngokuthembekile lokhu kubekezelelana ekukhiqizeni. Ngokomongo:
- Ukuphrinta kwe-3D kwensimbi okuphezulu (i-DMLS, i-EBM): okuvamile okungu-±50–100 μm, kanye nokuba lukhuni kwendawo okuvame ukudinga ukushintshwa okukhulu ngemuva komshini noma kunjalo
- Ukubumba ngomjovo oqondile ngezifakelo zensimbi: ±20–50 μm okungcono kakhulu, futhi kuncike kakhulu kwikhwalithi yesikhunta kanye nokuncishiswa kwezinto.
- Umshini wokugaya we-CNC one-axis ezi-5: inqubo ye-±2–5 μm, lapho izitolo ze-premium zifinyelela ku-±1 μm ekusethweni okuzinzile
2. Ukuguquguquka Okumangalisayo Kwezinto Ezisetshenziswayo
Ihadiwe ye-elekthronikhi ihlala ezindaweni ezishisayo kakhulu, zikagesi, kanye nezama-electromagnetic. Izinhlelo ezingaphansi ezahlukene zidinga izakhiwo zezinto ezihlukene kakhulu—ngezinye izikhathi ngaphakathi kwenhlangano efanayo. Ikhono lomshini we-CNC lokusebenza cishe nanoma yiziphi izinto zobunjiniyela lihlala liyinzuzo enkulu.Cabanga ngephalethi elitholakala kumhleli wezinhlelo ze-CNC:
Izinsimbi ezinokushisa okuphezulu kakhulu
