Ma Granite Surface Plate Afotokozedwa: DIN 876, ASME B89.3.7, GB ndi Federal Spec

Dipatimenti yabwino ikasankha mbale ya granite pamwamba, mzere wofunikira kwambiri pachithunzicho ndigirediGirediyo imafotokoza kupirira kwa flatness komwe wopanga ayenera kutsimikizira, ndipo imatsimikizira mwachindunji ngati mbaleyo ndi yoyenera ntchito yowunikira, kuyang'aniridwa kobwera, kapena kapangidwe ka chipinda chogulitsira. Vuto ndilakuti miyezo inayi imagwira ntchito limodzi pakugula padziko lonse lapansi: ChijeremaniDIN 876, waku AmericaASME B89.3.7ChitchainaGB/T 20428ndi USMafotokozedwe a Boma la Federal GGG-P-463cBukuli likufotokoza tanthauzo la giredi iliyonse, momwe mungawerengere kulekerera kwa flatness, komanso momwe mungasankhire giredi yotsika mtengo kwambiri pa ntchito yanu.

Kodi "Giredi" Imatanthauza Chiyani Kwenikweni?

Giredi ndi kalasi yosalala, osati kufotokozera mwala wokha. Pa giredi iliyonse, muyezo umafotokoza kusiyana kwakukulu kwa malo ogwirira ntchito kuchokera ku ndege yeniyeni, yoyezedwa kudutsa mopingasa kwa mbale ndikufotokozedwa mu ma micrometer (kapena mainchesi). Malamulo awiri amagwira ntchito pa miyezo yonse:

• Kulekerera kumakula malinga ndi kukula.Mbale ya 2000 × 1000 mm ya mtundu womwewo imakhala ndi kupirira kowirikiza kawiri kuposa mbale ya 1000 × 630 mm. Nthawi zonse yerekezerani kulekerera komwe kuli kutalika kofanana.
• Giredi iliyonse ndi theka la kulekerera kwa lotsatira.Kukwera giredi imodzi (monga, 0 → 00) ndi theka la kusiyana kovomerezeka; kutsika giredi imodzi kumawirikiza kawiri. Ichi ndichifukwa chake kusankha giredi yoyenera kumakhudza kwambiri mtengo.

Ogulitsa odziwika bwino amatsimikiza mbale iliyonse motsutsana ndi muyezo woyenera pamalo olamulidwa ndi kutentha (pafupifupi 20 °C) ndikupereka satifiketi yowunikira kapena yowunikira yokhala ndi miyeso yoyezedwa. Ngati mtengo sunatchule muyezo, giredi ndi chiphaso chovomerezeka cha flatness, chiwone ngati chosakwanira — onani zolemba zathu pakuyeza ndi kuyang'anira granite.

DIN 876 Maphunziro (000 / 00 / 0 / 1 / 2)

DIN 876-1 ndiye muyezo wodziwika kwambiri ku Europe ndi Asia. Umafotokoza magiredi asanu, kuyambira Giredi 000 yolondola kwambiri mpaka Giredi 2 yogwirira ntchito. Kulekerera kwapadera kwa mbale yokhala ndi1000 mm mopingasapafupifupi:

DIN 876 kalasi 00 kuphwanyikandiye muyezo womwe makampani ambiri owunikira amafunsa nthawi yomwe mbaleyo imathandizira zida zoyezera kapena ngati chizindikiro chogwira ntchito chowerengera. Kuti muyerekeze molondola, nthawi zonse funsani ogulitsa kuti anene mtengo wotsimikizika pa diagonal yeniyeni ya mbale yomwe mukugula, ndikutsimikiziranikulondola kwa mbale ya granite pamwambaimathandizidwa ndi satifiketi yolembedwa.

Magiredi a ASME B89.3.7 (AA / A / B)

Muyezo wa ku America wa ASME B89.3.7 umagwiritsa ntchito magiredi atatu a zilembo, owerengedwa kuchokera ku ma formula kutengera plate diagonal osati tebulo lokhazikika:

• Giredi AA (Giredi ya Laboratory)— kulekerera kwakukulu, komwe kumapangidwira ma lab a metrology ndi ma master reference plates.
• Giredi A (Giredi Yoyendera)— pafupifupi kawiri kulekerera kwa AA; chisankho chokhazikika cha madipatimenti owongolera khalidwe.
• Giredi B (Giredi ya Chipinda cha Zida)— pafupifupi kawiri kulekerera kwa A; koyenera kukonza, kupanga zida ndi ntchito yonse yopangira makina.

Monga njira yowerengera, ASME Giredi AA ikugwirizana kwambiri ndi DIN 876 Giredi 00, ndipo Giredi A ili pafupi ndi DIN Giredi 0. Mafomulawa ndi ofunika poyerekeza mawu: ogulitsa awiri omwe akugwiritsa ntchito mapepala a "Giredi A" a kukula kosiyana sapereka kulekerera kofanana pokhapokha ngati mzere wozungulira uli wofanana.

GB/T 20428 ndi Federal Spec GGG-P-463c

Muyezo wa dziko la ChinaGB/T 20428Pa ma granite pamwamba pa mbale, kapangidwe ka kalasi ndi nzeru zolekerera za 000 / 00 / 0 / 1 / 2 ndi DIN 876, kotero ma plate opangidwa ku China omwe ali ndi chitsimikizo cha GB 00 akhoza kuyesedwa motsutsana ndi zomwe DIN 00 imayembekezera - bola wopanga ayang'ana kutentha koyenera ndikulemba zotsatira zake.

Dziko la USMafotokozedwe a Boma la Federal GGG-P-463cndi chikalata chakale cha boma chomwe chimagwiritsanso ntchito magiredi a AA / A / B. Ma tender ambiri a boma la US ndi zojambula zakale zimatchulabe izi. Chalowedwa m'malo ndi ASME B89.3.7 mu ntchito zamalonda, koma mayina a magiredi amapitilira pa zojambula, kotero magulu ogula ayenera kutsimikizira kuti ndi chikalata chiti chomwe kulekerera kumatanthauza pamene chithunzi chimanena kuti "Giredi A" yokha.

Kuyerekeza kwa Magiredi Osiyanasiyana (Zosonyeza)

Dziwani: matebulo omwe ali pamwambapa ndi zitsanzo zosonyeza kutalika kwa ~ 1000 mm. Nthawi zonse onetsetsani kuti mulingo wololera ndi wotani poyerekeza ndi mtundu wamakono wa muyezo woyenera, ndipo funsani deta yoyezedwa ndi wopanga.

Momwe Mungawerengere ndi Kutsimikizira Kufotokozera kwa Flatness

1. Yang'anani muyezo wofotokozera ndi kope— “Giredi 00″ yopanda chizindikiro chokhazikika (DIN 876, GB/T 20428, ndi zina zotero) sichimveka bwino.
2. Tsimikizani kukula kozungulira komwe kwagwiritsidwa ntchito polekerera— kulolerana kumafotokozedwa pamwamba pa diagonal, osati m'lifupi.
3. Funsani za kusalala kwa malo ndi kulondola kobwerezabwereza kwa kuwerenga— mbale imatha kukhala yosalala koma yokhala ndi kugwedezeka komwe kumakhudza muyeso wa magawo ang'onoang'ono.
4. Amafuna satifiketi yokhala ndi miyeso yoyezedwa komanso kutsatirika— kuyeza koyenera komanso kolondola pansi pa 20 °C ndi komwe kumasintha umboni woti kulekerera ndi umboni. Ichi ndi gawo lofunika kwambiri lanjira yowunikira ndi kuwerengera.
5. Tchulani malo oimikapo magalimoto ndi makina othandizira— mbale ya Giredi 00 pa malo osakwanira sidzasunga mawonekedwe ake ovomerezeka. Zothandizira za mfundo zitatu kapena zochepetsera ndi gawo la phukusi lolondola.

Momwe Mungasankhire Giredi Yoyenera Popanda Kulipira Mopitirira Muyeso

Kugula zinthu mopitirira muyeso ndiko kutaya zinthu komwe kumachitika kawirikawiri; kugula zinthu motayirira kwambiri ndiko kulakwitsa kokwera mtengo kwambiri. Malangizo othandiza ochokera ku mapulojekiti mazana ambiri omwe akuyendetsedwa ndiNjira yopangira ya ZHHIMG®:

• Gwirizanitsani giredi ndi chida, osati kabuku.CMM imafuna malo okhazikika owunikira (Giredi 00/A yachizolowezi), pomwe tebulo lolembera m'sitolo yopanga zinthu silipindula chilichonse kuchokera ku Giredi 000.
• Gulani kukula kamodzi, perekani kawiri.Ndikotsika mtengo kugula kukula koyenera ndi giredi yolondola tsopano kusiyana ndi kubwerezanso kapena kusintha mbale yomwe idatchulidwa giredi imodzi yomasuka kwambiri kuti igwiritsidwe ntchito m'tsogolo.
• Ganizirani za ma ledges, inserts ndi ma thread boss pa siteji yofotokozera.Kuziwonjezera pambuyo pake kumachepetsa kusalala ndi kuchotsera chiphaso.
• Konzani nthawi zokonzanso zinthu.Ngakhale mbale yokhazikika ya granite iyenera kutsimikiziridwanso nthawi ndi nthawi; kusinthasintha kwa kulolera kumachitika pang'onopang'ono komanso kosaoneka.

Pa mapulojekiti omwe mbaleyo imaphatikizidwa mu makina kapena makina oyezera m'malo mogwiritsa ntchito yokha, zofunikira pa geometry nthawi zambiri zimalembedwa pagawo lililonse pachithunzicho — gulu lathu limatha kuwonanso kulolerana ndikuthandizira zonse zomwe zafotokozedwa, kuyambira kusankha zinthu mpaka kutumiza kovomerezeka, monga tafotokozera munkhani yathu.luso la granite lolondola.

Mapeto

Ma granite surface plate ndi chilankhulo chogwirizana pakati pa dipatimenti yanu yabwino ndi wopanga — koma pokhapokha ngati aliyense atchula muyezo womwewo, kukula kwake, ndi mtengo wovomerezeka. Kaya chojambula chanu chikuyitanitsa DIN 876 Grade 00, ASME Grade AA kapena GB/T 20428 Grade 0, ZHHIMG® imapanga ndikutsimikizira ma framework onse anayi, ndi muyeso wotsatira m'mikhalidwe yolamulidwa ndi kutentha.

Kodi mwakonzeka kufotokoza mbale yanu? Titumizireni kukula, giredi yofunikira kapena muyezo, ndi fomu yanu yofunsira — mainjiniya athu adzatsimikizira kupirira kwa flatness, adzapereka chithandizo cha makina, ndikulemba mtengo ndi lipoti lovomerezeka lowunikira.
