Kukhazikika Kwanthawi Yaitali: Ubwino wa Moyo wa Utumiki wa Mbale Zapamwamba za Granite za Giredi 00

Ogula ambiri amafunsa za kulekerera kuphwanyika akamayitanitsambale ya pamwamba pa granite. Ochepa amafunsa kuti kulolerana kumeneko kudzakhala kwa nthawi yayitali bwanji. Ndi funso labwino kulisiya mukamayerekeza mawu, koma ndi funso lomwe limakhala lofunika kwambiri pazaka zitatu kapena zisanu mu moyo wa ntchito wa munthu - ndipo ndi pomwe kusiyana pakati pa magiredi kumaonekera.

Ma granite pamwamba nthawi zambiri amagawidwa m'magulu motsatira miyezo monga DIN 876, ASME B89.3.7, kapena GB/T 22095, ndi magiredi kuyambira AA mpaka A, B, ndi 0/00 kutengera muyezo womwe wagwiritsidwa ntchito. Giredi 00 ili pamwamba - kupirira kolimba kwambiri komwe mbale ingavomerezedwe, nthawi zambiri kumasungidwa ma master reference plates, ma calibration lab, ndi ntchito zomwe muyeso wina uliwonse mnyumbamo umachokera ku malo amodzi amenewo. Gawo losangalatsa si nambala yoyamba pa satifiketi. Ndi zomwe zimachitika ndi nambala imeneyo pakapita nthawi.

Chifukwa Chake Mapepala Otsika Amayenda Mofulumira

Kusalala kwa mbale pamwamba si chinthu chokhazikika; ndi chithunzi chomwe chimatengedwa poyang'anitsitsa komaliza. Kuyambira pamenepo, zinthu zitatu zimatsimikiza momwe imagwirira ntchito bwino:

Kuchuluka kwa zinthu ndi kapangidwe ka tinthu. Mwala wochepa, kapena mwala wokhala ndi tinthu tosasinthasintha, nthawi zambiri umatha mosagwirizana ndi chida chobwerezabwereza komanso mbali zina. Madontho ataliatali a microscopic amawonongeka mofulumira kuposa pamwamba pake, ndipo kupindika kwa thabwalo kumayamba kusuntha — pang'onopang'ono poyamba, kenako kumawonekeratu patatha zaka zingapo kugwiritsidwa ntchito tsiku ndi tsiku. Granite wakuda wokhuthala, wolemera makilogalamu 3,000+/m³, umalimbana bwino ndi kuvala kosiyanasiyana kumeneku, zomwe ndi chifukwa chake ndi chinthu chomwe chimasankhidwa pa ntchito ya Giredi 00 m'malo mwa miyala yopepuka kapena yopepuka.

Kupera ndi kulumikiza bwino. Kulowetsa mbale mpaka Giredi 00 sikungokhala kosalala pa tsiku loyamba - nthawi zambiri kumatsirizidwa kudzera mu ndondomeko yayitali komanso yowongoleredwa bwino ya kulumikiza yomwe imasiya kapangidwe kofanana kwambiri pansi pa kulekerera komwe kumayesedwa. Mbale yotsika mtengo imatha kuwerenga pafupifupi nambala yomweyo kuchokera pamzere, zomwe zimachitika kudzera mu kukonza mwachangu, koma popanda kusinthasintha kwakukulu pakumaliza kwa pansi. Kusiyana kumeneko sikuonekera pa pepala lofotokozera; kumawonekera momwe mbaleyo imakalamba.

Kusamalira ndi kusunga pambuyo pa satifiketi, zomwe tafotokoza kwina, koma ziyenera kubwerezedwanso apa - ngakhale mbale ya Giredi 00 imataya ubwino wake ngati isungidwa pamalo osafanana kapena kusiyidwa m'chipinda chomwe kutentha kwake sikuli bwino.

Kodi Izi Zikutanthauza Chiyani pa Ma Calibration Cycles?

Mwachizolowezi, kusiyana kwa magiredi kumatanthauza kuchuluka kwa ma recalibration. Sitolo yomwe imagwiritsa ntchito mbale ya Giredi B pamzere wotanganidwa ingafunike kuyang'ananso ndikuyibwerezanso chaka chilichonse, nthawi zina nthawi zambiri kutengera momwe imagwiritsidwira ntchito. Mbale yowunikira ya Giredi 00, yosamalidwa bwino pamalo olamulidwa, nthawi zambiri imatha kukhala zaka ziwiri kapena zitatu pakati pa ma recalibration athunthu - ngakhale izi zimasiyana malinga ndi momwe zimagwiritsidwira ntchito ndipo siziyenera kuonedwa ngati lamulo lokhazikika. Pa labu yowunikira kapena dipatimenti yowunikira yomwe imagwira ntchito ngati malo owunikira malo onse, nthawi yayitaliyo si kungopulumutsa ndalama zokha. Imachepetsa kuchuluka kwa nthawi zomwe kupanga kuyenera kuyimitsidwa, kapena ma recalibration achiwiri ayenera kubweretsedwa, pomwe mbale yoyamba yachotsedwa kuti itsimikizidwenso.

Tapereka mapepala a Giredi 00 kwa makasitomala omwe amawagwiritsa ntchito ngati chizindikiro chachikulu chomwe chipinda chawo chonse cha CMM chimatsimikiziridwa - madipatimenti a metrology aku yunivesite, mabungwe apadziko lonse, ndi malo angapo opanga zinthu a Fortune 500 pakati pawo. Chomwe chimadabwitsa ogula koyamba si nambala ya flatness yokha, chifukwa ogulitsa ambiri odziwika bwino amatha kupeza ziwerengero zofanana papepala. Ndi pempho, chaka chimodzi kapena ziwiri pambuyo pake, kuti deta yoyambirira ya calibration iyendere poyerekeza ndi kuyang'ananso - ndikupeza kusiyana komwe kudakali mkati mwa gawo la satifiketi yoyambirira. Kutsimikizira kobwerezabwereza kumeneku, kochitidwa moona mtima ndi zida zotsatirika, ndiyo njira yokhayo yodziwira ngati pempho la Giredi 00 linapezedwa kapena linangoyesedwa kamodzi kokha pansi pa mikhalidwe yabwino.

Chidziwitso Chothandiza kwa Ogula

Giredi 00 sikofunikira pa ntchito iliyonse — pakuwunika kapena kusonkhanitsa, mbale ya Giredi A kapena B nthawi zambiri imakhala chisankho chanzeru komanso chotsika mtengo. Koma pa ma reference akuluakulu, calibration ya gauge, kapena gawo lililonse lomwe mbaleyo imakhala yokhazikika, kukhazikika kwa nthawi yayitali kwa mbale ya Giredi 00 yopangidwa bwino kumapereka chifukwa chokwera mtengo. Mayeso enieni si satifiketi yomwe imatumizidwa ndi mbaleyo. Ndi zomwe satifiketiyo imanenabe kwa zaka zitatu, pansi pa mikhalidwe iliyonse yomwe mbaleyo yakhalamo.
