Pankhani yoyezera molondola, granite straightedge, monga chida chofunikira chotsimikizira kulondola kwa zida ndi muyeso, kalasi yake yosalala imakhudza mwachindunji kudalirika kwa zotsatira zoyezera. Chitsimikizo cha National Institute of Standards and Technology (NIST) cha ku United States ndi muyezo wodziwika padziko lonse lapansi wa zida zoyezera molondola kwambiri, ndipo kusalala kwa AA-level ndi chimodzi mwa magiredi omwe ali ndi zofunikira kwambiri zolondola. Monga kampani yotsogola mumakampani, ZHHIMG, yokhala ndi ukadaulo wake wapamwamba komanso luso lake lokhwima, imathandiza ogwiritsa ntchito kukwaniritsa ziphaso za NIST ndi zolinga za kusalala kwa AA-level kwa owongolera granite. Zotsatirazi zikupatsani kusanthula kwatsatanetsatane kwa mfundo zazikulu zoyezera ndi njira zoyendetsera.
1. Mvetsetsani satifiketi ya NIST ndi muyezo wa flatness wa AA-level
Satifiketi ya NIST imadziwika ndi njira zake zoyesera komanso kuwunika mozama, cholinga chake chachikulu ndikuwonetsetsa kuti zida zoyezera zikukwaniritsa miyezo yolondola padziko lonse lapansi. Pankhani ya granite straightedge, kufunikira kwa AA grade flatness ndi kokhwima kwambiri. Nthawi zambiri, zimanenedwa kuti cholakwika cha flatness mkati mwa kutalika kwa mita iliyonse chiyenera kulamulidwa mkati mwa ± 0.5μm. Muyezo uwu umapereka zofunikira kwambiri pazinthu zakuthupi, ukadaulo wokonza ndi ukadaulo wowerengera wa straightedge. Granite straightedge ya AA-level yotsimikiziridwa ndi NIST si chitsimikizo chodalirika cha muyeso wolondola kwambiri, komanso umboni wamphamvu wa mphamvu zaukadaulo za kampaniyo komanso mtundu wa malonda.
II. Maziko Abwino a ZHHIMG granite straightedge
Chowongolera cha granite cha ZHHIMG chakhazikitsa maziko olondola kwambiri kuyambira siteji yosankha zinthu. Granite yachilengedwe yapamwamba kwambiri, yokhala ndi kristalo wambiri wamkati ndi kapangidwe kofanana, ili ndi coefficient yokulitsa kutentha yotsika ngati 5-7 × 10⁻⁶/℃, ndipo ili ndi kukhazikika kwachilengedwe komanso kuthekera koletsa kusokonekera, zomwe zimapangitsa kuti ikhale yosalala pamlingo wa AA. Panthawi yokonza, ZHHIMG imagwiritsa ntchito njira zapamwamba monga kupukuta ndi kupukuta kwa CNC, kuphatikiza ndi zida zodziwira bwino kwambiri monga laser interferometers kuti zigwiritsidwe ntchito nthawi yeniyeni, kuti zitsimikizire kuti pamwamba pa chowongoleracho pamakhala kulondola kwambiri koyambirira panthawi yokonza, zomwe zimapangitsa kuti pakhale mikhalidwe yabwino yogwirira ntchito yowunikira pambuyo pake.
Iii. Kukonzekera Kusakonzedwa
Musanayambe kuwerengera satifiketi ya NIST, ndikofunikira kuonetsetsa kuti straightedge ili bwino kwambiri. Choyamba, pamwamba pa straightedge payenera kutsukidwa bwino kwambiri. Gwiritsani ntchito nsalu yopanda ulusi ndi chotsukira chapadera kuti muchotse madontho a mafuta, fumbi ndi zonyansa zina pamwamba kuti mupewe zodetsa zomwe zingakhudze kulondola kwa calibration. Kachiwiri, ikani straightedge pamalo okhala ndi kutentha ndi chinyezi chokhazikika kwa maola opitilira 24 kuti igwirizane mokwanira ndi kutentha ndi chinyezi cha chilengedwe, kuchotsa zolakwika zazing'ono zomwe zingachitike chifukwa cha kusintha kwa chilengedwe. Kuphatikiza apo, zida zowerengera zolondola kwambiri monga laser interferometers ndi milingo yamagetsi ziyenera kukonzedwa. Kulondola kwa zida izi kumakhudza mwachindunji kulondola kwa zotsatira za calibration.
Iv. Njira Yoyezera ndi Maukadaulo Ofunika
Kuyeza kolakwika: Gwiritsani ntchito mulingo wamagetsi kuti muyese koyamba m'mphepete wowongoka. Sonkhanitsani malo oyezera nthawi zina (monga 100mm) kuti mupeze deta yoyerekeza ya pamwamba pa m'mphepete wowongoka. Kutengera zotsatira za muyeso, pamwamba pa m'mphepete wowongoka unapangidwa mwaluso pogwiritsa ntchito zida zopukutira za CNC kuti muchotse malo okwera oonekera bwino, zomwe zimapangitsa kuti kusalalako kufikire poyamba zofunikira za muyezo wa AA.
Kuyeza molondola: Kuyeza molondola kwambiri kumachitika pogwiritsa ntchito laser interferometer, yomwe imatha kuzindikira molondola kusintha kwa kutalika pamwamba pa straightedge pa mulingo wa micrometer. Kutengera ndi deta yomwe idaperekedwa ndi interferometer, pamwamba pa straightedge idaphwanyidwa bwino pophatikiza kupukutira ndi CNC machining. Panthawi yopukutira, kuthamanga ndi njira yopukutira ziyenera kusinthidwa nthawi zonse kuti pang'onopang'ono kuthetsedwe cholakwika cha flatness, kuti flatness ya straightedge ifike pamlingo wapamwamba.
Kutsimikizira mobwerezabwereza ndi kukonza bwino: Mukamaliza kukonza bwino, gwiritsani ntchito laser interferometer ndi electronic level kuti mufufuze bwino straightedge kachiwiri kuti muwonetsetse kuti cholakwika cha flatness cha malo aliwonse oyezera chili mkati mwa muyezo wa AA-level. Ngati zolakwika zazing'ono zapezeka m'dera lanu, kukonza bwino kuyenera kuchitika mpaka flatness yonse ya straightedge ikwaniritse mokwanira zofunikira za AA-level za NIST certification.
V. Kufunsira ndi Kuwunikanso Chitsimikizo cha NIST
Mukamaliza kuwerengera ndikutsimikizira kuti straightedge yafika pamlingo wa AA, mutha kutumiza fomu yofunsira satifiketi ku NIST. Panthawi yofunsira, magawo aukadaulo a straightedge, mafotokozedwe aukadaulo wokonza, zolemba za calibration ndi zinthu zina ziyenera kuperekedwa. NIST idzatumiza akatswiri owunikira kuti akayang'ane ndikuwunika straightedge pamalopo. Kuwunikaku kudzakhudza zinthu zingapo monga kusalala, kukhazikika kwa kutentha, komanso kukana kuwonongeka kwa straightedge. Granite straightedge yokha yomwe yadutsa kuwunikira kokhwima ndi yomwe ingapeze satifiketi ya NIST ndikukhala chinthu choyezera bwino.
Potsatira malangizo owunikira a granite straightedge a ZHHIMG omwe atchulidwa pamwambapa, mabizinesi ndi mabungwe ofufuza amatha kukwaniritsa ziphaso za NIST ndi zolinga za flatness za AA mogwira mtima kwambiri. Kaya m'mafakitale omwe ali ndi zofunikira kwambiri monga kupanga makina, ndege, kapena ma chips amagetsi, granite straightedge ya ZHHIMG yovomerezedwa ndi NIST idzakhala bwenzi lodalirika pakuwonetsetsa kuti muyeso ndi wabwino komanso kuti zinthu zikuyenda bwino, kuthandiza mabizinesi kupitilizabe kupita patsogolo pantchito yowunikira molondola ndikupita patsogolo ku tsogolo lolondola kwambiri.
