Ingxenye Efihliwe Emishinini Ye-Semiconductor: Lokho Okwenziwa Yizisekelo Ze-Granite Empeleni

Vula indawo yokugcina yesistimu yokuhlola i-wafer, i-CMM, noma ipulatifomu ye-laser ye-femtosecond, futhi endaweni ethile ngaphansi kwezigaba zokukhanya nokunyakaza, kukhona itshe elimnyama elenza umsebenzi othule, ongemuhle. Alibonakali ezintweni zokumaketha zemishini. Akekho olibonisa embukisweni wezohwebo. Kodwa uma lihluleka ukuhlala liqondile, akukho okunye okubalulekile emshinini.

Kungani izinhlelo zokunyakaza zidinga isisekelo "esifile"

Imishini yokunemba — amathuluzi okulinganisa isithombe esine-axis ekabili, amatafula e-XY, amapulatifomu e-linear motor,izinhlelo zokuhlola amathuluzi— bonke babelana ngesidingo esisodwa okulula ukusikhohlwa: isisekelo kumele singabi namandla okusebenza ngomshini nangokushisa uma kuqhathaniswa nakho konke okuhamba phezu kwaso. Onjiniyela ngezinye izikhathi babiza lesi sakhiwo ngokuthi “sifile,” okusho ukuthi asizwakali, asiguquguquki, futhi asikhuli ngokungalingani lapho imishini esizungezile ishisa ngesikhathi sokusebenza.

I-Granite ifanelana nale ndima ngezizathu ezimbalwa zesakhiwo. Ubuningi bayo obuphezulu buyinika izici ezinamandla zokudlidliza, okubaluleke kakhulu emishinini ehlezi eduze kwezitezi zokukhiqiza ezinezinjini zokuphakamisa, ama-conveyor motor, noma amanye amathuluzi omshini asebenza eduze. Isakhiwo sayo sekristalu simelana nohlobo lokukhukhuleka kwesikhathi eside okuboniswa ezinye izinsimbi kanye nezinhlanganisela ngaphansi komthwalo oqhubekayo - isisekelo se-granite esibambe i-gantry endaweni efanayo iminyaka emihlanu, ngokomthetho, kufanele silinganise okufanayo ngosuku lwe-1,825 njengoba senza ngosuku lokuqala.

Lapho lokhu kusetshenziswa khona ngempela

Uhlu lwezicelo zezisekelo ze-granite kanye nezinhlangano lukhule kakhulu ngale kwamalebhu endabuko okukala imitha:

• Inqubo ye-semiconductor kanye nemishini yokuhlola, lapho ukubeka isigaba sezinga le-nanometer kuncike esisekelweni esingashukumi ngokushisa okumaphakathi.
• Ukubhoboza nge-PCB kanye nemishini yokwakha, lapho ukunemba kwesikhundla se-spindle phezu kwetafula elikhulu lokusebenza kunquma ngqo isivuno.
• Imishini yokulinganisa edidiyelwe (i-CMM) kanye namathuluzi okulinganisa iphrofayili ye-optical, lapho ubuso be-granite buvame ukusebenza njengendiza ye-zero-reference kuyo yonke imithamo elandelayo.
• I-AOI (ukuhlolwa okuzenzakalelayo kwe-optical) kanye nezinhlelo ze-CT/X-ray zezimboni, lapho ukuzinza kwemishini kuthinta khona ukunemba kokubhaliswa kwesithombe.
• Imigqa emisha yokuhlola amandla nebhethri, uhlelo lokusebenza olusha kodwa olukhula ngokushesha njengoba abakhiqizi bamabhethri bethatha ukubekezelelana okuqinile kokuhlolwa kweseli nemodyuli.
• Imishini yokulinganisa yomugqa kanye ne-ball-screw, lapho isisekelo se-granite ngokwaso siyingxenye yochungechunge lokulinganisa.

Eziningi zalezi zinhlelo, ingxenye ye-granite ayithengiswa njengomkhiqizo oqediwe kumakhasimende okugcina — kuyinhlanganisela encane umakhi wemishini ayihlanganisa emshinini omkhulu. Lokho kusho ukuthi i-tolerance stack ibalulekile: ukuba yisicaba, ukulingana, kanye ne-squareness specs esisekelweni se-granite kusakazeka ngqo ekunembeni kokugcina umakhi wemishini angayikhangisa kumakhasimende akhe.

Imininingwane yomhlangano enganakwa

Isisekelo se-granite asivamile ukuthunyelwa njengetshe elingavuthiwe. Izinhlelo eziningi zokunemba zidinga ukufakwa kwensimbi, amaphakethe okuthwala umoya, izintambo zokufaka, noma izingxenye ezincane eziboshiwe — izinzwa, ama-rails, noma ama-bracket — ezihlanganiswe kwi-granite ngaphambi kokuba ifike kumakhi wemishini. Lesi sinyathelo sokuhlanganisa ngokuvamile senzeka endaweni elawulwayo, njengoba uthuli noma ukushintshashintsha kokushisa ngesikhathi sokubopha kungaletha uhlobo oluqondile lokungazinzi i-granite eyakhethwa ukukuqeda kwasekuqaleni.

Kwabakhi bemishini abathola lezi zingxenye, imibuzo ewusizo okufanele ibuzwe umhlinzeki ayibalulekile ngombala wetshe kodwa imayelana nokulawula inqubo: Lingakanani izinga lokushisa lokusebenza endaweni yokuhlanganisa? Yimiphi imishini yokulinganisa eqinisekisa ukuthi ithambile ngaphambi kokuthunyelwa, futhi ingabe leyo mishini ngokwayo ingalandelelwa esikhungweni sikazwelonke se-metrology? Ingcezu ipakishwa futhi ibekwe kanjani ukuze ithuthwe, njengoba isisekelo se-granite singaba nesisindo samathani amaningana futhi ukushaya okukodwa ngesikhathi sokuthunyelwa kungaletha umfantu ongabonakali emehlweni kodwa obonakala ngaphansi kokulinganiswa kamuva?

Lena imininingwane ehlukanisa isisekelo se-granite esigcina imininingwane yaso iminyaka eyishumi kuleyo elimaza ukunemba komshini ngokuthula phakathi nonyaka.
