Xa icandelo lomgangatho lichaza ipleyiti yomphezulu wegranite, umgca omnye obalulekileyo kumzobo nguloibakala. Olu didi luchaza ukunyamezelana kokuthe tyaba okumele kuqinisekiswe ngumvelisi, kwaye lugqiba ngokuthe ngqo ukuba ipleyiti ifanelekile na kumsebenzi wokulinganisa, ukuhlolwa okungenayo, okanye uyilo oluqhelekileyo lomgangatho wevenkile. Umngeni kukuba imigangatho emine ephambili iyafana ekuthengweni kwehlabathi: isiJamaniI-DIN 876, waseMelikaI-ASME B89.3.7, IsiTshayinaI-GB/T 20428, kunye ne-USIinkcukacha zeSizwe GGG-P-463cEsi sikhokelo sichaza ukuba ithetha ukuthini ibakala ngalinye, indlela yokufunda ukunyamezelana kokuthamba, kunye nendlela yokukhetha ibakala elingabizi kakhulu kwisicelo sakho.
Yintoni kanye kanye echazwa "liBanga"?
Ibanga liklasi yokusicaba, kungekhona inkcazo yelitye ngokwalo. Kwibanga ngalinye, umgangatho uchaza ukuphambuka okuphezulu komphezulu osebenzayo ukusuka kwindawo yokwenyani, olinganiswa kwi-diagonal yeplate kwaye ubonakaliswe kwi-micrometers (okanye ii-intshi). Imithetho emibini isebenza kuyo yonke imigangatho:
- Izikali zokunyamezelana ngokobukhulu.Ipleyiti engama-2000 × 1000 mm yodidi olufanayo inomlinganiselo ophindwe kabini kunowepleyiti engama-1000 × 630 mm. Soloko uthelekisa ii-tolerances ezinobude obufanayo obuthe tyaba.
- Ibanga ngalinye limalunga nesiqingatha sokunyamezelana kwenqanaba elilandelayo.Ukunyuka kwinqanaba elinye (umz., 0 → 00) kuyenza ibe sisiqingatha sendlela yokuphambuka evumelekileyo; ukwehla kwelinye kwinqanaba kuyayiphinda kabini loo nto. Yiyo loo nto ukukhetha izinga elifanelekileyo kunefuthe elikhulu kwixabiso.
Ababoneleli abadumileyo baqinisekisa ipleyiti nganye ngokuchasene nomgangatho ofanelekileyo kwindawo elawulwa bubushushu (efanelekileyo yi-20 °C) baze bakhuphe isatifikethi sokulinganisa okanye sokuhlola esinamaxabiso alinganisiweyo. Ukuba ikowuteshini ayichazi inani elisemgangathweni, inqanaba kunye neliqinisekisiweyo lokutyibilika, yiphathe njengengaphelelanga — bona amanqaku ethu kuukulinganisa kunye nokuhlola i-granite.
I-DIN 876 Amabanga (000 / 00 / 0 / 1 / 2)
I-DIN 876-1 yeyona migangatho ikhankanywa kakhulu eYurophu nase-Asia. Ichaza amanqanaba amahlanu, ukusuka kwiBanga 000 elichanekileyo kakhulu ukuya kwiBanga 2 leworkshop. Ukunyamezelana okuqhelekileyo kokusicaba kwepleyiti eneI-diagonal eyi-1000 mmmalunga:

I-DIN 876 grade 00 flatnessyeyona ndlela ininzi iinkampani zokuhlola eziyifunayo xa ipleyiti ixhasa izixhobo zokulinganisa okanye isebenza njengesalathiso esisebenzayo sokulinganisa. Ukuze ufumane uthelekiso oluchanekileyo, soloko ucela ababoneleli ukuba bachaze ixabiso eliqinisekisiweyo kwi-diagonal yokwenyani yepleyiti oyithengayo, kwaye uqinisekise ukubaukuchaneka kwepleyiti yomphezulu wegraniteixhaswa sisatifikethi esibhaliweyo.
Amanqanaba e-ASME B89.3.7 (AA / A / B)
I-ASME B89.3.7 esemgangathweni yaseMelika isebenzisa amanqanaba oonobumba abathathu, abalwe kwiifomyula ezisekelwe kwi-diagonal yepleyiti endaweni yetafile esisigxina:
- Ibanga le-AA (Ibanga leLebhu)— ukunyamezelana okuqinileyo, okwenzelwe iilebhu zemetrology kunye neepleyiti eziphambili zesalathiso.
- Ibanga A (Ibanga loVavanyo)— malunga nokuphindwa kabini kokunyamezelana kwe-AA; ukhetho oluqhelekileyo lwamasebe olawulo lomgangatho.
- Ibanga B (Ibanga leGumbi lezixhobo)— malunga nokuphindwa kabini kokunyamezelana kwe-A; ifanelekile kuyilo, ukwenza izixhobo kunye nomsebenzi wokulungisa ngokubanzi.
Njengereferensi engqalileyo, i-ASME Grade AA ihambelana ngokusondeleyo ne-DIN 876 Grade 00 ngokwesakhono, kwaye iGrade A ikufutshane ne-DIN Grade 0. Iifomyula zibalulekile xa kuthelekiswa iikowuteshini: abathengisi ababini abacaphula iipleyiti "zeGrade A" ezinobukhulu obahlukeneyo abaniki unyamezelo olufanayo ngaphandle kokuba i-diagonal iyafana.
I-GB/T 20428 kunye ne-Federal Spec GGG-P-463c
Umgangatho wesizwe waseTshayinaI-GB/T 20428Kwi-granite surface plates, ulwakhiwo lweklasi kunye nefilosofi yokunyamezelana efana ne-DIN 876, ngoko ke ii-plates ezenziwe eTshayina eziqinisekisiweyo kwi-GB 00 zinokuvavanywa ngokuchasene nolindelo lwe-DIN 00 - ukuba umenzi uhlola phantsi kobushushu obulawulwayo kwaye abhale phantsi iziphumo.
I-USIinkcukacha zeSizwe GGG-P-463cluxwebhu oludala lukarhulumente olusebenzisa amabakala e-AA / A / B. Iithenda ezininzi zikarhulumente wase-US kunye nemizobo yelifa zisakhankanywa. Ithathelwe indawo yi-ASME B89.3.7 kwimisebenzi yorhwebo, kodwa amagama amabakala ayaqhubeka kwimizobo, ngoko ke amaqela okuthenga kufuneka aqinisekise ukuba loluphi uxwebhu olubhekiselele kulo ukunyamezela xa umzobo uthi "iBakala A" kuphela.
