Ipleyiti yomphezulu wegranite sisiseko somlinganiselo wobukhulu. Yindawo ephambili yokubhekisa apho zonke ezinye izilinganiso zithelekiswa khona. Kodwa ayizizo zonke iipleyiti zomphezulu ezenziwe zalingana—kwaye ayizizo zonke imigangatho efanayo. Ukuba uchaza ipleyiti yomphezulu yelebhu ye-metrology, isebe lokuhlola, okanye isikhungo sokulinganisa, ukuqonda umahluko phakathi kwemigangatho ye-DIN, i-ASME, kunye ne-JIS akupheleli nje kwimfundo. Ngumahluko phakathi kokuthenga ipleyiti ehlangabezana neemfuno zakho kunye nokuthenga engahlangabezaniyo neemfuno zakho.
Imeko yeMigangatho
Imigangatho eliqela yamazwe ngamazwe ilawula ukuchaneka kunye nokulinganiswa kweepleyiti zomphezulu wegranite. Ezona zikhankanyiweyo ngokubanzi ziquka:
- I-DIN 876 (umgangatho waseJamani), egubungela iipleyiti zomphezulu ukuze zihlolwe kwaye zilinganiswe
- I-ASME B89.3.7 (umgangatho waseMelika), owathatha indawo ye-Federal Specification yangaphambili i-GGG-P-463C
- I-JIS B 7513 (umgangatho waseJapan), egubungela iipleyiti zomphezulu ukuze kulinganiswe ngokuchanekileyo
- I-GB/T 20428 (umgangatho waseTshayina)
- I-BS 817 (umgangatho waseBritane)
Umgangatho ngamnye uchaza amanqanaba ahlukeneyo okuchaneka, iindlela zovavanyo, kunye nemigangatho yokwamkelwa. Ipleyiti ehlangabezana neDIN 876 Grade 00 isenokungahlangabezani ne-ASME B89.3.7 Grade AA—kwaye ngokuchaseneyo.
Ukuqonda amaBanga okuChaneka
Ukuchaneka kwepleyiti yomphezulu wegranite kudla ngokubonakaliswa ngokwemeko yokunyamezelana kokusicaba phezu komphezulu osebenzayo wepleyiti. Nantsi intelekelelo ngokubanzi:
| Ibanga | Ukunyamezelana Okuqhelekileyo Kokuthe tye | Isicelo Esiqhelekileyo |
|---|---|---|
| I-DIN 876 Ibanga 00 | ± 0.001 mm/m | Isalathiso selabhoratri, i-metrology echanekileyo kakhulu |
| I-DIN 876 Ibanga 0 | ± 0.002 mm/m | Ukuhlolwa, ukulinganiswa |
| I-ASME B89.3.7 Ibanga le-AA | ±(1.0 + L/250) μm | Ukulinganisa okuchanekileyo |
| I-ASME B89.3.7 Ibanga A | ±(2.0 + L/250) μm | Uhlolo ngokubanzi |
| Ibanga le-JIS 0 | ± 0.003 mm/m | Ukulinganisa ngokuchanekileyo |
| Ibanga loku-1 le-JIS | ± 0.006 mm/m | Uhlolo lweworkshop |
L = ubude obude bepleyiti nge-mm
Into ebalulekileyo ekufuneka uyiqwalasele: ipleyiti ethi “Grade 00″ phantsi kwe-DIN ayifani kangako nethi “Grade AA” phantsi kwe-ASME. Iindlela zovavanyo zahlukile, amanqaku okulinganisa ahlukile, kwaye iikhrayitheriya zokwamkelwa zahlukile.
Yintoni Omele Uyijonge Kwipleyiti Yomphezulu Osemgangathweni
Ngaphaya komgangatho wokuchaneka, zininzi izinto ezigqiba ukuba ipleyiti yomphezulu iya kusebenza njengoko kulindelekile na ngexesha lomsebenzi wayo:
Umgangatho wezinto ezisetyenzisiweyo. I-granite kufuneka ibe nobukhulu obucolekileyo, ingabi naziphene, kwaye ibe nobunzima obufanayo. I-granite ekumgangatho ophantsi ingaba nee-micro-fractures ezichaphazela uzinzo lwexesha elide. Kwi-ZHHIMG®, sisebenzisa i-granite emnyama ye-ZHHIMG® enobunzima obuyi-≈3100 kg/m³—ephezulu kunezinye ii-granite ezimnyama zaseYurophu naseMelika—ukuqinisekisa uzinzo oluphezulu kunye nokumelana nokuguguleka.
Ukuqina kunye nokuxhathisa ukuguguleka. Ipleyiti yomphezulu kufuneka imelane nokukrweleka kunye nokuguguleka ngenxa yokusetyenziswa ngokuphindaphindiweyo. Igranite yethu ifikelela kubunzima beMohs obuyi-6-7, ibonelela ngokumelana nokuguguleka okugqwesileyo kangangeminyaka emininzi yokusetyenziswa kwemihla ngemihla.
Uzinzo lobushushu. I-CTE yegranite kufuneka ibe sezantsi kwaye iqikeleleke kangangoko kunokwenzeka. Igranite yethu emnyama ye-ZHHIMG® inika uzinzo olukhethekileyo lobushushu, igcina ubuthe tyaba kuzo zonke iinguqu zobushushu ezinokubangela ukuba iipleyiti zesinyithi zigobe.
Ukulinganisa kunye nokuLandelela. Ipleyiti kufuneka ize nesatifikethi sokulinganisa esilandela imilinganiselo sibuyele kwiziko lesizwe le-metrology. Kwi-ZHHIMG®, yonke ipleyiti yomphezulu ilinganiswa kusetyenziswa izixhobo eziqinisekiswe yiJinan Institute of Metrology kunye neShandong Institute of Metrology, kunye nokulandeleleka kwiNational Institute of Metrology yaseTshayina.
Indima yoBuchule boBugcisa
Negranite ebalaseleyo ayisebenzi ngaphandle kokugqitywa kakuhle.ipleyiti yomphezulu wegraniteIbandakanya amanqanaba amabini aphambili: ukulungiswa okungenanto kunye nokulungiswa ngokuchanekileyo. Isithuba esingenanto sinqunyulwa ukusuka kwibhloko eyombiweyo, emva koko sicolwe ngokuchanekileyo ukuya kwindawo ethe tyaba. Kodwa inyathelo lokugqibela—ukufikelela kwinqanaba elichaziweyo lokuthamba—lifuna ukugoba ngesandla ngobuchule.
Iingcali ezinobuchule zilungisa ngononophelo umphezulu wepleyiti ukuze zifikelele ekuthe tyaba nasekugudeni okufunekayo. Yonke into kufuneka iphumelele uhlolo olungqongqo ukuqinisekisa ukuba iyahlangabezana nomgangatho ochaziweyo. Kwi-ZHHIMG®, ii-grinders zethu eziphambili zinamava angaphezu kweminyaka engama-30 okusebenzisa isandla, zifikelela ekuthe tyaba kwinqanaba le-micrometer ngokusebenzisa uvakalelo oluchukumisekayo olungenakwenziwa matshini.
Iingcebiso Ezisebenzayo Kubathengi
Xa uthelekisa iikowuteshini ezivela kubavelisi abahlukeneyo, musa ukuthembela kwigama lezinto kuphela. Isicelo:
- Uxinano lokwenyani lwegranite (hayi nje "igranite" kodwa uhlobo oluthile kunye noxinano)
- I-CTE (i-coefficient of thermal expansion) ilinganiswa kwi-20°C
- Ukunyamezelana kokuthe tyaba okufezekisiweyo kunye nomgangatho olinganiswa ngawo
- Isatifikethi sokulinganisa kunye namaxwebhu okulandelela umkhondo
- Isiqinisekiso sobomi benkonzo kunye nomgaqo-nkqubo wokuphinda ubekwe umphezulu
Ukuba umthengisi akanakukwazi ukubonelela ngezi nkcukacha, loo nto ithetha ukuba abenzi abaninzi abancinci basebenzisa imabula engabizi kakhulu endaweni yegranite yokwenyani—indlela ekhohlisayo esiyichasayo kakhulu. Imabula ithambile, ayizinzanga kangako, kwaye idla ngokuguga kunegranite efanelekileyo. Umahluko awuncinci; ngumahluko phakathi kwepleyiti yomphezulu egcina ukuchaneka kwayo amashumi eminyaka kunye nenye ephuma ngaphandle kwengcaciso kwiminyaka embalwa.
Ukugcinwa kunye nokuhlaziywa kwesatifikethi
Ipleyiti yomphezulu wegranite ayilotyalo-mali "lokuyibeka uze uyilibale". Kwaneepleyiti ezilungileyo zifuna ukuhlaziywa rhoqo ukuqinisekisa ukuba azikaphumi ekunyamezeleni. I-ASME B89.3.7 igubungela isiqinisekiso esitsha, ukuhlaziywa kwakhona kwicandelo, kunye nokuhlaziywa kwakhona emva kokulungiswa kwakhona. I-DIN 876 kunye ne-JIS B 7513 zinemigaqo efanayo.
Ukugcinwa rhoqo—ukucoca ngezinyibilikisi ezifanelekileyo, ukukhusela umphezulu ekutshatyalalisweni, nokusebenzisa izigqubuthelo ezifanelekileyo xa ungasetyenziswa—kwandisa ubomi benkonzo yepleyiti yomphezulu kakhulu. Kwaye xa ipleyiti ekugqibeleni iguga ngaphaya kokunyamezela kwayo okumiselweyo, ukuphinda ibekwe ngumchwephesha oqeqeshiweyo kunokuyibuyisela kwimeko yayo entsha.
Apha kwi-ZHHIMG®, asenzi nje kuphela iipleyiti zomphezulu. Sibonelela ngenkxaso epheleleyo yomjikelo wobomi—ukusuka kwiinkcazo zokuqala kunye nokulinganiswa ngokuhlaziya kunye nokuphinda ufake umphezulu—kuba siyaqonda ukuba ipleyiti yomphezulu ayisosixhobo nje. Sisisiseko senkqubo yakho yokulinganisa yonke.
