Mbale ya granite pamwamba yomwe imalembedwa kuti "Giredi 00" pa satifiketi yake, mwa lingaliro, iyenera kusinthidwa ndi mbale ina iliyonse ya Giredi 00 yomwe ili pamsika. M'malo mwake, mainjiniya a QC amadziwa kuti izi sizowona nthawi zonse. Mbale ziwiri zimatha kukhala ndi ziphaso zofanana zosalala ndipo zimakhalabe zosiyana pa moyo wautumiki wazaka ziwiri - imodzi imagwira ntchito yake yowunikira, inayo ikuchoka pakulekerera mwachangu kuposa momwe amayembekezera. Chomwe ogula osinthasintha nthawi zambiri amanyalanyaza si njira yopera. Ndi zinthu zopangira zokha.
Ili ndi vuto losatha komanso losakambidwa mokwanira muchida choyezera graniteunyolo wogulira: marble wochepa, wopangidwa ndi miyala yakuda ndi yomalizidwa kuti iwoneke yosiyana ndi granite wakuda weniweni, nthawi zambiri imagulitsidwa pansi pa mndandanda wa "granite surface plate" kapena "granite square ruler". Kwa wogula kuyerekeza mawu pa pepala lofotokozera, kusiyana sikuonekera mpaka gawolo litayamba kale kugwira ntchito. Kumvetsetsa kuchuluka komwe kumakuuzani za chida choyezera granite - ndi momwe mungatsimikizire - ndi imodzi mwa njira zothandiza kwambiri zogwirira ntchito musanapereke oda yogulira.
Chifukwa Chake Kuchulukana Ndi Katundu Womwe Umaneneratu Zina Zonse
Kuchulukana si nambala yokha yomwe ili pa pepala la zinthu. Mu zinthu zomwe zimagwiritsidwa ntchito m'malo mwa granite ndi granite, ndi njira yodalirika yopangira kapangidwe ka kristalo ka mkati komwe kamatsimikizira kuuma, kukana kuwonongeka, komanso kukhazikika kwa nthawi yayitali.
Zimene Granite Yakuda Yokhala ndi Kuchuluka Kwambiri Imapereka
Granite wakuda weniweni wokhala ndi mphamvu zambiri, womwe uli pamtunda wa pafupifupi 3,100 kg/m³, uli pamwamba pa kuchuluka kwa granite komwe nthawi zambiri kumagwirizanitsidwa ndi mitundu ya marble kapena granite yotsika yomwe nthawi zambiri imalowetsedwa m'malo osungiramo ndalama. Kusiyana kwa kuchuluka kumeneku kumatanthauza mipata yoyezera magwiridwe antchito:
- • Kulimba kwambiri komanso kulimba — granite wokhuthala amalimbana ndi kusokonekera pang'ono pansi pa katundu, zomwe ndizofunikira kwambiri pama plates apamwamba ndi m'mbali zowongoka zomwe zimagwiritsidwa ntchito ngati zero-reference datums
- • Kukana kukalamba bwino — kapangidwe ka kristalo kolimba kamalimbana ndi kusweka kwa pamwamba chifukwa cha kukhudzana mobwerezabwereza kwa probe, kutsetsereka kwa gauge block, ndi kugwira ntchito ndi zinthu zina.
- • Kuchepa kwa ma porosity — kumachepetsa kuyamwa kwa chinyezi, zomwe ndizofunikira chifukwa chinyezi chomwe chimayamwa chingayambitse kutupa kwa mawonekedwe ang'onoang'ono komanso kusinthasintha kwa mawerengedwe m'malo ozizira.
- • Kusunga bwino kusalala kwa nthawi yayitali — zinthu zokhuthala sizimavuta kusuntha pang'onopang'ono kapena kukhazikika komwe kumatha kusuntha mbale pang'onopang'ono kuchoka pamlingo wake wovomerezeka pakapita zaka zambiri ikugwiritsidwa ntchito.
Mosiyana ndi zimenezi, miyala ya marble nthawi zambiri imakhala ndi kapangidwe kolimba komanso kosinthasintha ka kristalo, kachulukidwe kochepa, komanso porosity yapamwamba - zomwe zimapangitsa kuti zikhale zosavuta komanso zotsika mtengo kukumba ndi kumaliza, koma sizikugwirizana ndi kusunga ma sub-micron tolerances kwa nthawi yayitali.
Momwe Kuchulukana Kumakhudzira DIN 876 Flatness Grading
DIN 876 — muyezo womwe umatchulidwa kwambiri pa kusalala kwa granite pamwamba pa mbale — umatanthauzira magiredi anayi olekerera (00, 0, 1, 2), iliyonse imafotokoza kupendekeka kovomerezeka kosalala kutengera malo a mbaleyo. Chomwe DIN 876 sichinatchule mwachindunji ndi kuchuluka kwa zinthu zoyambira kapena kapangidwe kake. Ichi ndichifukwa chake mbale ziwiri zonse zimatha kukhala ndi dzina la "Giredi 00" pomwe zimasiyana kwambiri ndi zinthu zomwe zili pansi pa nthaka — girediyo imatsimikizira kusalala panthawi yowunikira, osati kuthekera kwanthawi yayitali kwa chinthucho kusunga kusalalako.
Kwa ogula, izi zikutanthauza kuti satifiketi ya DIN 876 iyenera kuonedwa ngati mfundo yofunikira koma yosakwanira. Kuigwirizanitsa ndi mfundo yotsimikizika ya kuchuluka kwa zinthu kumapereka chithunzi chokwanira cha nthawi yomwe ntchitoyo ikuyembekezeka.
Momwe Mungatsimikizire Kuchuluka kwa Granite Musanapereke Order Yogula
Zonena za kuchuluka kwa zinthu zomwe zili pa pepala lofotokozera n'zosavuta kuzifotokoza, ndipo mwatsoka, sizimatsimikiziridwa nthawi zonse paokha musanatumize. Njira zingapo zotsimikizira:
Pemphani Deta Yoyesera Kuchuluka kwa Munthu Wachitatu kapena Wamkati mwa Nyumba
- • Funsani ogulitsa kuti akuuzeni zotsatira zenizeni zoyezedwa za kuchuluka kwa madzi (kudzera mu njira yosinthira madzi/Archimedes) kuchokera ku gulu la zinthu zomwe zilipo, osati avareji ya mafakitale wamba.
- • Ngati n'kotheka, pemphani chitsanzo chaching'ono cha zinthu kuti chitsimikizidwe pa labu musanapereke oda yayikulu.
- • Onani kuchuluka kwa granite wakuda weniweni monga momwe wogulitsa amanenera - mtengo wake ndi wochepera ~2,700–2,800 kg/m³.
Unikani Zomangamanga za Calibration za Wogulitsa
Wopanga zinthu amene amasamala kwambiri za umphumphu wa zinthu nthawi zambiri amaika ndalama mu zomangamanga zoyezera kuti athandizire izi:
- • Zipangizo zoyezera mphamvu monga ma laser interferometer, ma level amagetsi, ndi ma inductive displacement gauges, ndi ziphaso zomwe zingatsatidwe ku bungwe la dziko lonse la metrology.
- • Malo owunikira kutentha ndi chinyezi omwe amalamulidwa ndi kutentha ndi chinyezi, popeza kuyeza kwa kusalala komwe kumatengedwa m'chipinda chosalamulirika kumabweretsa kusiyana kwawo.
- • Zofunikira pa zida zopukusira (monga, zopukusira zazikulu zolondola pamwamba zomwe zimatha kukonza kutalika kotalikirapo), zomwe zimagwirizana ndi kuthekera kosunga zolekerera zolimba nthawi zonse pa mbale zazikulu.
Magulu a Zida Zoyezera Zomwe Zimagwiritsidwa Ntchito Kwambiri
- • Ma granite pamwamba — amagwiritsidwa ntchito ngati ma datum oyambira; kuchulukana kumakhudza mwachindunji kukhazikika kwa flatness kwa nthawi yayitali
- • Ma granite straight rulers ndi ma square rulers — ma assembling ndi ma arrangement references pomwe zinthu sizikuyenda bwino
- • Ma block a Granite V ndi ofanana — kukhudzana mobwerezabwereza ndi katundu womangirira kumapangitsa kuti kukana kukalamba kukhale kofunika kwambiri
- • Zigawo zonyamulira mpweya wa granite — kukhazikika kwa pamwamba pa nanometer kumadalira kwambiri kapangidwe ka mkati ka zinthu zomwe zili mkati mwake.
Kodi Izi Zikutanthauza Chiyani kwa QC ndi Magulu Ogula Zinthu?
Palibe chilichonse mwa izi chomwe chikusonyeza kuti zida zonse zotsika mtengo za granite sizoyenera — pa ntchito wamba, zosafunikira kwenikweni, kusiyana kwa kulekerera ndi mtengo kungakhale koyenera. Vutoli makamaka ndi kulemba molakwika — miyala ya marble kapena miyala yotsika mtengo yomwe imagulitsidwa popanda kuulula ngati yofanana ndi granite wakuda wochuluka kwambiri, cholinga chake ndi ogula omwe alibe njira yosavuta yotsimikizira zomwe akunena asanagule.
Pa ntchito zomwe chida choyezera chimagwira ntchito ngati chowerengera, deta yolumikizira, kapena chopangira cha nthawi yayitali, chopempha deta yotsimikizika ya kuchuluka kwa zinthu pamodzi ndi DIN 876 (kapena JIS, GB, ASME, BS 817-1983 yofanana, kapena GOST 10905) satifiketi yokhazikika ndi sitepe yotsika mtengo komanso yamtengo wapatali yotsimikizira. Imatenga imelo imodzi yowonjezera mu ndondomeko ya RFQ ndipo imatha kuchepetsa kwambiri chiopsezo cha kugwedezeka kosayembekezereka miyezi kapena zaka mutakhazikitsa.
Mapeto
Satifiketi yokhazikika imakuuzani momwe chida choyezera granite chinagwirira ntchito tsiku lomwe chinayang'aniridwa. Kuchuluka kwa zinthu kumakuuzani momwe zingakhalire kuti zikwaniritse giredi yachiwiri, zisanu, kapena khumi pambuyo pake. Kwa mainjiniya a QC ndi magulu ogula omwe amatchula mbale za granite pamwamba, ma ruler, kapena zida zoyezera molondola, mfundo zonse ziwiri ndizofunikira - ndipo palibe chomwe chiyenera kutengedwa popanda zikalata zothandizira.
ZHHIMG imapanga zida zoyezera granite molondola komanso zigawo zake kuchokera ku granite wakuda wokhuthala kwambiri (≈3,100 kg/m³), woyesedwa motsatira DIN 876 ndi miyezo yofanana yapadziko lonse lapansi yokhazikika, ndipo kuwunikako kumatha kutsatiridwa ndi zida zovomerezeka zoyezera. Owerenga omwe akuyesa zofunikira za polojekiti yomwe ikubwera alandiridwa kuti apemphe zikalata zoyezera kuchuluka ndi kuwerengera pawww.zhhimg.com.
