Ndidawona lipoti lotere kalekale: asayansi aku Germany, Japan ndi mayiko ena adakhala zaka 5 ndipo adawononga pafupifupi yuan miliyoni 10 kuti apange mpira wopangidwa ndi zinthu zoyera kwambiri za silicon-28.Mpira wa silicon wa 1kg uwu umafunika makina opangidwa mwaluso kwambiri, kupera ndi kupukuta, kuyeza molunjika (kuzungulira, kukhwimitsa ndi mtundu), tinganene kuti ndi mpira wozungulira kwambiri padziko lonse lapansi.
Tiyeni tidziwitse njira yopukutira mwaluso kwambiri.
01 Kusiyana pakati pa kugaya ndi kupukuta
Kupera: Pogwiritsa ntchito particles abrasive TACHIMATA kapena mbamuikha pa akupera chida, pamwamba anamaliza ndi wachibale kayendedwe ka akupera chida ndi workpiece pansi pa mavuto ena.Kupera kumatha kugwiritsidwa ntchito popanga zinthu zosiyanasiyana zachitsulo komanso zopanda zitsulo.Maonekedwe a pamwamba okonzedwa amaphatikizapo ndege, mkati ndi kunja kwa cylindrical ndi conical pamwamba, convex ndi concave spherical surfaces, ulusi, mano ndi mbiri zina.Kulondola kwa processing kumatha kufika IT5 ~ IT1, ndipo kuuma kwapamwamba kumatha kufika ku Ra0.63 ~ 0.01μm.
Kupulitsa: Njira yopangira yomwe imachepetsa kuuma kwa malo ogwirira ntchito pogwiritsa ntchito makina, mankhwala kapena electrochemical action kuti ipeze malo owala komanso osalala.
Kusiyana kwakukulu pakati pa ziwirizi ndikuti mapeto a pamwamba omwe amapezedwa ndi kupukuta ndi apamwamba kuposa akupera, ndipo njira za mankhwala kapena electrochemical zingagwiritsidwe ntchito, pamene kugaya kwenikweni kumagwiritsa ntchito njira zamakina, ndipo kukula kwa njere komwe kumagwiritsidwa ntchito kumakhala kokulirapo kuposa komwe kumagwiritsidwa ntchito. kupukuta.Ndiko kuti, kukula kwa tinthu ndi kwakukulu.
02 Ukadaulo wopukutira bwino kwambiri
Kupukuta kolondola kwambiri ndi moyo wamakampani amakono amagetsi
Ntchito yaukadaulo wopukutira mwaluso kwambiri mumakampani amakono amagetsi sikungopanga ziwiya zosiyanasiyana, komanso kufoletsa zida zosanjikiza zingapo, kuti zowotcha za silicon za mamilimita angapo lalikulu zitha kupanga masauzande ku VLSI wopangidwa ndi mamiliyoni ambiri. ma transistors.Mwachitsanzo, kompyuta yopangidwa ndi anthu yasintha kuchoka pa matani makumi ambiri kufika pa magalamu mazana ambiri masiku ano, zomwe sizingachitike popanda kupukuta bwino kwambiri.
Kutenga mwachitsanzo, kupukuta ndi gawo lomaliza la ndondomeko yonseyi, cholinga chake ndikuwongolera zolakwika zazing'ono zomwe zatsala ndi ndondomeko yapitayi yopangira mkate kuti mupeze kufanana kwabwino.Mulingo wamakono wamakampani azidziwitso a optoelectronic umafunikira kufananiza kowonjezereka kwa zinthu za optoelectronic gawo lapansi monga safiro ndi silikoni wa crystal imodzi, zomwe zafika pamlingo wa nanometer.Izi zikutanthauza kuti kupukuta kwalowanso mulingo wolondola kwambiri wa nanometers.
Momwe kupukuta kwapamwamba kwambiri kuli kofunikira pakupanga kwamakono, minda yake yogwiritsira ntchito imatha kufotokoza molunjika vutoli, kuphatikizapo kupanga makina osakanikirana, zida zachipatala, zida zamagalimoto, zipangizo zamakono, nkhungu zolondola komanso zamlengalenga.
Ukadaulo wapamwamba wopukutira umangodziwika ndi mayiko angapo monga United States ndi Japan
Chida chachikulu cha makina opukutira ndi "grinding disc".Ultra-mwatsatanetsatane kupukuta ali pafupifupi okhwima zofunika pa zikuchokera zinthu ndi zofunika luso la akupera chimbale mu kupukuta makina.Mtundu woterewu wazitsulo wachitsulo wopangidwa kuchokera ku zipangizo zapadera suyenera kungokwaniritsa kulondola kwa nano-level ya ntchito yokha, komanso kukhala ndi coefficient yolondola yowonjezera kutentha.
Pamene makina opukutira akuthamanga kwambiri, ngati kuwonjezereka kwa kutentha kumayambitsa kutentha kwa disc yogaya, flatness ndi kufanana kwa gawo lapansi sikungatsimikizidwe.Ndipo mtundu uwu wa zolakwika zakusintha kwamafuta zomwe sizingaloledwe kuchitika si mamilimita ochepa kapena ma microns ochepa, koma ma nanometer ochepa.
Pakali pano, pamwamba mayiko kupukuta njira monga United States ndi Japan akhoza kale kukwaniritsa zolondola kupukuta zofunika 60 inchi gawo lapansi zopangira (omwe ndi wapamwamba-kakulidwe).Kutengera izi, adziwa luso laukadaulo laukadaulo wowongolera bwino kwambiri ndipo amvetsetsa bwino zomwe zikuchitika pamsika wapadziko lonse lapansi..M'malo mwake, kudziwa lusoli kumayang'aniranso chitukuko cha makampani opanga zamagetsi pamlingo waukulu.
Poyang'anizana ndi kutsekeka kolimba kwaukadaulo kotere, pankhani ya kupukuta kopitilira muyeso, dziko langa limatha kudzifufuza panokha.
Kodi ukadaulo waku China wopukutira molunjika kwambiri ndi wotani?
M'malo mwake, pankhani ya kupukuta kopitilira muyeso, China ilibe zopambana.
Mu 2011, "Cerium Oxide Microsphere Particle Size Standard Material and Its Preparation Technology" yopangidwa ndi gulu la Dr. Wang Qi kuchokera ku National Center for Nanoscale Sciences ya Chinese Academy of Sciences inapambana mphoto yoyamba ya China Petroleum ndi Chemical Industry. Mphotho ya Federation's Technology Invention Award, ndi zida zofananira za nanoscale particle size standard Anapeza chiphaso cha dziko choyezera chida komanso chiphaso chapadziko lonse lapansi chamtundu woyamba.Kuyeserera koyeserera kopitilira muyeso kwa zinthu zatsopano za cerium oxide zaposa zida zachikhalidwe zakunja kamodzi kokha, kudzaza kusiyana kwa gawoli.
Koma Dr. Wang Qi anati: “Izi sizikutanthauza kuti takwera pamwamba pa ntchitoyi.Kwa ndondomeko yonse, pali madzi opukutira okha koma palibe makina opukuta kwambiri.Nthawi zambiri timangogulitsa zinthu.”
Mu 2019, gulu lofufuza la Pulofesa Yuan Julong waku Zhejiang University of Technology adapanga ukadaulo wopangira makina opangira ma abrasive.Makina angapo opukutira opangidwa adapangidwa ndi Yuhuan CNC Machine Tool Co., Ltd., ndipo adadziwika kuti iPhone4 ndi iPad3 galasi ndi Apple.Chida chokhacho chopukutira cholondola kwambiri padziko lonse lapansi chapanel ndi aluminiyamu alloy backplane polishing, makina opukutira opitilira 1,700 amagwiritsidwa ntchito popanga magalasi a Apple a iPhone ndi iPad.
Chithumwa cha makina processing chagona mu izi.Kuti mutengere gawo la msika ndi phindu, muyenera kuyesetsa momwe mungathere kuti mugwirizane ndi ena, ndipo mtsogoleri wa teknoloji nthawi zonse amasintha ndikusintha, kuti akhale oyeretsedwa, kupikisana nthawi zonse ndikugwira, ndikulimbikitsa chitukuko chachikulu cha luso la anthu.
