Kodi Kulondola kwa Precision Granite Surface Plate Kumatenga Nthawi Yaitali Bwanji, Ndipo Kodi Kukhazikika Kwa Nthawi Yaitali Kuyenera Kuganiziridwa Posankha?

Ma granite pamwamba pake amaonedwa kuti ndi maziko a njira zoyezera molondola kwambiri komanso zosonkhanitsira. Kuyambira ma laboratories a metrology mpaka kusonkhanitsa zida za semiconductor ndi malo olondola a CNC, nsanja za granite zimadaliridwa chifukwa cha kukhazikika kwawo, kukana kuwonongeka, komanso kutentha. Komabe funso lomwe limafunsidwa kawirikawiri ndi mainjiniya ndi oyang'anira khalidwe ndi losavuta kwambiri: kodi kulondola kwa nsanja ya granite molondola kumatenga nthawi yayitali bwanji, ndipo kodi kukhazikika kwa nthawi yayitali kolondola kukhale chinthu chofunikira posankha imodzi?

Mosiyana ndi zida zogwiritsidwa ntchito kapena zida zamagetsi,nsanja yolondola ya graniteilibe "tsiku lokhazikika lotha ntchito." Nthawi yake yolondola imadalira kuphatikiza kwa zinthu, njira zopangira, momwe zimagwiritsidwira ntchito, komanso kuwongolera chilengedwe kwa nthawi yayitali. Mu ntchito zoyendetsedwa bwino, mbale yapamwamba ya granite imatha kusunga kusalala kwake komanso mawonekedwe ake kwa zaka zambiri. Komabe, m'malo osalamuliridwa bwino, kuwonongeka kwa kulondola kumatha kuchitika mwachangu kwambiri, nthawi zina mkati mwa zaka zingapo.

Chipangizocho chokha chimagwira ntchito yofunika kwambiri pakukhazikika kwa nthawi yayitali. Granite wakuda wokhala ndi makulidwe abwino komanso ofanana amapereka kukana kwakukulu ku kupumula kwamkati komanso kusokonekera pang'ono pakapita nthawi. Granite yokhala ndi makulidwe pafupifupi 3100 kg/m³ imawonetsa makhalidwe abwino kwambiri onyowa komanso khalidwe lochepa loyenda, zomwe ndizofunikira kuti zikhale zosalala pansi pa katundu wokhazikika. Miyala yocheperako kapena zinthu zosasankhidwa bwino, kuphatikiza marble yomwe imagwiritsidwa ntchito molakwika ngati granite, poyamba imatha kukwaniritsa zofunikira za kusalala koma imakonda kuyenda mwachangu pamene kupsinjika kwamkati kumasulidwa ikagwiritsidwa ntchito.

Ubwino wopanga ndi wofunikanso kwambiri. Mapulatifomu olondola a granite omwe amasinthidwa ndi zokometsera, kuchepetsa kupsinjika, komanso kukalamba nthawi yayitali asanapunthidwe komaliza amasonyeza kukhazikika kwabwino kwa nthawi yayitali. Njira zamakono zopangira ndi kulumikiza manja zomwe akatswiri odziwa bwino ntchito amachita zimathandiza kuti malo osalala afike pamlingo wa micrometer kapena nanometer. Chofunika kwambiri, njirayi imatsimikizira kuti mawonekedwe a pamwamba amakhalabe olimba pambuyo poyika, m'malo mosintha pang'onopang'ono pamene kupsinjika kotsala kumatha. Mapulatifomu opangidwa ndi ukalamba wosakwanira kapena kupanga mwachangu nthawi zambiri amawonetsa kutayika kolondola koyezeka pakapita nthawi, ngakhale malipoti oyamba owunikira akuwoneka odabwitsa.

Mkhalidwe wa chilengedwe umakhudza nthawi zonse komanso mokulirapo moyo wolondola wambale ya pamwamba pa graniteKusintha kwa kutentha, chithandizo chosafanana, kugwedezeka, ndi kusintha kwa chinyezi zonse zimapangitsa kuti pakhale zoopsa za kusintha kwa kutentha kwa nthawi yayitali. Granite ili ndi coefficient yochepa ya kukula kwa kutentha, koma siili yotetezeka ku kutentha kwa kutentha. Nsanja yomwe imakumana ndi kusintha kwa kutentha kwa tsiku ndi tsiku kapena magwero otentha am'deralo imatha kukhala ndi kupindika pang'ono komwe kumakhudza kudalirika kwa muyeso. Ichi ndichifukwa chake kukhazikika kwa kulondola kwa nthawi yayitali sikungasiyanitsidwe ndi kukhazikitsidwa koyenera, malo othandizira okhazikika, komanso malo oyezera olamulidwa.

Magwiritsidwe ntchito a granite amathandizanso kudziwa nthawi yomwe kulondola kumakhala mkati mwa zomwe zafotokozedwa. Pulatifomu yolondola ya granite yomwe imagwiritsidwa ntchito ngati maziko ofotokozera ntchito zoyezera kuwala imakalamba mosiyana ndi yomwe imathandizira zida zolemera zamakina kapena katundu wobwerezabwereza. Katundu wokhuthala, kunyamula molakwika, kapena kusamutsa pafupipafupi kumatha kuyambitsa kupsinjika pang'ono m'nyumbamo. Pakapita nthawi, kupsinjika kumeneku kungasinthe mawonekedwe a pamwamba, ngakhale mu granite yapamwamba kwambiri. Kumvetsetsa momwe nsanjayo idzagwiritsidwire ntchito m'mikhalidwe yeniyeni ndikofunikira poyesa magwiridwe antchito olondola kwa nthawi yayitali.

Njira zowunikira ndi kutsimikizira zimapereka chizindikiro chomveka bwino cha nthawi yogwira ntchito yolondola ya nsanja. M'malo mongoganiza kuti nthawi yogwira ntchito ndi yokhazikika, ogwiritsa ntchito akatswiri amadalira kuwunika nthawi ndi nthawi kuti atsimikizire kuti kusalala ndi mawonekedwe ake zimakhalabe mkati mwa kulekerera. M'malo okhazikika, nthawi zowunikiranso za chaka chimodzi mpaka ziwiri ndizofala, ndipo nsanja zambiri zimawonetsa kusinthasintha pang'ono ngakhale zitagwiritsidwa ntchito nthawi yayitali. M'malo ovuta kwambiri amafakitale, kutsimikizira mobwerezabwereza kungafunike, osati chifukwa chakuti granite imawonongeka mwachangu, koma chifukwa chakuti zinthu zachilengedwe zimasonkhana mwachangu.

Posankha mbale yolondola ya granite pamwamba, kukhazikika kwa kulondola kwa nthawi yayitali sikuyenera kuonedwa ngati lingaliro lomaliza. Kukhazikika koyamba kokha sikukuwonetsa momwe nsanjayo idzagwirira ntchito patatha zaka zisanu kapena khumi. Mainjiniya ayenera kuganizira za mawonekedwe a granite, kukalamba, njira zopangira, komanso kugwirizana ndi malo omwe akufunidwa. Nsanja yosankhidwa bwino ya granite imakhala chuma chogwiritsidwa ntchito kwa nthawi yayitali m'malo mokhala nkhani yokonzanso mobwerezabwereza.

Mu mafakitale amakono olondola kwambiri, kulondola sikumayesedwa panthawi yoperekedwa kokha. Kumayesedwa pakapita nthawi, pansi pa katundu, komanso pakusintha kwa zinthu. Pulatifomu yolondola ya granite yomwe imasunga mawonekedwe ake chaka ndi chaka imathandizira zotsatira zoyezera nthawi zonse, kuphatikiza zida zodalirika, komanso kuchepetsa ndalama zobwezeretsanso. Izi ndizofunikira kwambiri pakugwiritsa ntchito monga kupanga ma semiconductor, kuyang'anira kuwala, makina oyezera ogwirizana, ndi makina apamwamba a CNC, komwe ngakhale kusintha pang'ono kumatha kufalikira kukhala zolakwika zazikulu pambuyo pake.

Pomaliza, phindu lenileni la mbale yolondola ya granite pamwamba lili ndi kuthekera kwake kukhalabe yokhazikika nthawi yayitali atayiyika. Mwa kuika patsogolo kukhazikika kolondola kwa nthawi yayitali pakusankha, ogwiritsa ntchito amatha kuwonetsetsa kuti maziko awo oyezera amakhalabe odalirika nthawi yonse ya moyo wa zida zawo. Mu uinjiniya wolondola, kusinthasintha pakapita nthawi si chinthu chapamwamba; ndiye muyezo wofunikira kwambiri.
