Ipleyiti yomphezulu wegranite lutyalo-mali lwexesha elide, intsingiselo yempahla ehlala ixesha elide kwihlabathi le-metrology. Sekunjalo, esi sixhobo sibalulekileyo asikhuselekanga ekugugeni, ekonakalisweni, okanye ekulahlekelweni kokugungqa ngokuhamba kwexesha. Kuye nawuphi na umphathi wolawulo lomgangatho, ukuqonda kungekuphela nje ukhetho olufanelekileyo lwepleyiti yomphezulu wokuhlola igranite kodwa neenkqubo zokulungiswa kwepleyiti yomphezulu wegranite kubaluleke kakhulu ekunciphiseni ixesha lokungasebenzi kunye nokugcina ukuchaneka. Ulindelo lokuba ipleyiti yomphezulu, nokuba yipleyiti yomphezulu wegranite okanye olunye uphawu oluphambili, iya kugcina ukugungqa kwayo okuqinisekisiweyo ngonaphakade akukho ngqiqweni.
Indlela Ezigugile Ngayo Izinto Ezisetyenziswa Ngayo: Kutheni Kufuneka Ukulungiswa Kweepleyiti Zegranite Surface Plate
Isizathu esiphambili sokuba ipleyiti yegranite ifune ukugcinwa kukuguguleka kwendawo. Kwanegranite emnyama enzima kakhulu iguguleka kukungqubana okungapheliyo okuvela kwizixhobo zokulinganisa, izinto zokusebenza, kunye namasuntswana othuli arhabaxa. Oku kuguguleka kudla ngokubonakala kwiindawo zokuguguleka okuphezulu, okwenzeka apho izixhobo ezifana neegeyiji zokuphakama zihlala zibekwa kwaye zishukunyiswa, kudala ukuntywila okuncinci okuphazamisa ukufundwa kokuphinda-phinda kwendawo. Olu luphawu lokuqala lokuba ukulungiswa kwepleyiti yomphezulu wegranite ngobuchwephesha kunokufuneka. Ukongeza, impembelelo ngengozi kwimiphetho okanye kwiikona zepleyiti inokubangela ukuqhekeka; ngelixa iitships ezikude nendawo yokusebenza zisenokungachaphazeli ngokuthe ngqo ukuguguleka, zinokonakalisa ukuthembeka kwesakhiwo kwaye zibonise ukuphathwa okurhabaxa. Ngaphezu koko, kwiminyaka emininzi yokusetyenziswa kakhulu, ipleyiti yonke inokuwa kancinci kancinci kwinqanaba layo eliqinisekisiweyo (umz., ipleyiti yeBanga 0 inokwehla iye kwiBanga 1 lokunyamezela). Oku kufuna ukuphinda kufakwe umphezulu ngokupheleleyo. Xa ukunyamezela okufunekayo komsebenzi wokuhlola kungasafezekiswa, isisombululo asikokutshintshwa, kodwa yinkqubo yokulungisa ekhethekileyo ebizwa ngokuba kukuphinda kufakwe umphezulu okanye ukuphinda kufakwe umphezulu. Oku kubandakanya iingcali ezinobuchule obuphezulu eziguguleka ngononophelo iindawo eziphakamileyo kwipleyiti zisebenzisa iikhompawundi ezirhabaxa kunye neepleyiti ezinkulu zereferensi, zibuyisela ukuguguleka ngaphakathi kokunyamezela okuqinisekisiweyo. Le nkonzo ikhethekileyo yandisa ubomi bepleyiti ngokungenammiselo, nto leyo eyenza ukuba ibe yinxalenye ebalulekileyo yolawulo lwezixhobo zemetrology.
Umgangatho weGolide: Yintoni iMigangatho yePlate yoMphezulu weGranite?
Ukuze ulawule ngokufanelekileyo ilebhu ye-metrology, umntu kufuneka aqale achaze ukuba yintoni na umgangatho wokuchaneka kweplate yomphezulu wegranite. Lo mgangatho ubhekisa kumanqanaba okunyamezelana aqatshelweyo kwihlabathi liphela (AA, 0, kunye no-1) amiselwe ziinkcukacha ezifana ne-US Federal Specification GGG-P-463c okanye i-German DIN 876. La maxwebhu ayalela ukuphambuka okuphezulu okuvumelekileyo ukusuka kwindawo egqibeleleyo, okuqinisekisa ukutshintshwa kweendawo kunye nokulinganisa kwihlabathi liphela. Nangona kunjalo, umgangatho wokwenyani ukwabandakanya ifilosofi yokufumana izinto ezithembekileyo. Abavelisi abafana neplate yomphezulu wegranite okanye ezinye iimpawu ezimiselweyo banamathela kwiindlela ezingqongqo zokulawula umgangatho, kungekuphela nje ekufezekiseni ukuthamba kokuqala kodwa ekuqinisekiseni umgangatho wegranite emnyama eluhlaza—ukuqinisekisa ukuba inomxholo we-quartz ophantsi, uxinano oluphezulu, kunye ne-coefficient ephantsi yokwandiswa kobushushu (CTE) ukumelana notshintsho lobukhulu ngenxa yokuguquguquka kobushushu. Iplate yomphezulu wokuhlolwa kwegranite ethengwe kumthengisi othembekileyo inesiqinisekiso sokuba izinto ngokwazo zifanelekile kumsebenzi ochanekileyo.
Ukuxhobisa Ukuhlolwa: Indima yePlati yoMphezulu weGranite enePosi yoMqondisi
Umsebenzi ophambili owenziwa kwipleyiti yokuhlola umphezulu wegranite kukulinganisa okuthelekisayo, apho umgangatho owaziwayo (ibhloko yegage) usetyenziselwa ukuseta igeyiji, kwaye umsebenzi ulinganiswa ngokomlinganiselo omiselweyo. Le nkqubo idla ngokusebenzisa ipleyiti yomphezulu wegranite eneposti yesalathisi. Iposti yesalathisi, edla ngokuba yikholamu eqinileyo efakwe kwisiseko semagnethi okanye soomatshini, ibamba isalathisi sovavanyo lwedayali okanye iprobe yedijithali. Uzinzo lwayo lubalulekile ekulinganisweni ngokuchanekileyo. Ngelixa iigeyiji zekholamu ezilula zinokushukunyiswa zijikeleze ipleyiti, ukuba nepleyiti eyenzelwe ngokukodwa ukudibanisa ezi zinto zenza kube lula inkqubo yokuhlola. Ipleyiti yomphezulu wegranite eneposti yesalathisi idla ngokuthetha ukuseta okuhlala kuhleli, okuzinzileyo kakhulu, ngamanye amaxesha kusetyenziswa izinto ezifakwe ngemisonto ngaphakathi komphezulu wepleyiti ukuze zibophe iposti ngokuthe ngqo, zisuse intshukumo encinci okanye ukuthambekela okunokwenzeka ngeziseko zemagnethi. Ngaphezu koko, igranite ibonelela ngedatha efanelekileyo yokuseta inqaku le-zero yesalathisi kusetyenziswa ibhloko yegage, kwaye iposti yesalathisi igcina ukuphakama kunye nokuma, iqinisekisa ukulinganisa okuphindaphindwayo kakhulu, okusisiseko se-metrology yokuhlolwa. Olu kuhlanganiswa kweposti ezinzileyo kunye nepleyiti yomphezulu wokuhlolwa kwegranite eqinisekisiweyo kwandisa ukuchaneka okunokwenzeka kwenkqubo yokulinganisa yonke, kuguqula i-slab elula ibe sisikhululo sokulinganisa esipheleleyo nesichanekileyo.
Ukugcina Ukuthembeka kwePlate yoHlolo lweGranite
Ukhathalelo lokuthintela luhlala lubiza kancinci kunokulungiswa kwepleyiti yomphezulu wegranite. Nangona ukuguguleka kungenakuphepheka, izinga layo linokuncipha kakhulu ngokucoca indlu ngendlela efanelekileyo. Utshaba olukhulu lwepleyiti luthuli kunye nothuli, olusebenza njengodaka olurhabaxa phantsi kwezixhobo. Abasebenzisi kufuneka bacoce ipleyiti ngaphambi nasemva kokusetyenziswa ngakunye ngesicoci sepleyiti yomphezulu esikhethekileyo, kwaye bangaze barhuqe izinto ezinzima phezu komphezulu. Ekugqibeleni, ukuzibophelela kumgangatho we-metrology kuthetha ukwamkela umjikelo wobomi ofunekayo wezi zixhobo: ukukhetha ngononophelo, ukusetyenziswa, ukulinganiswa okucwangcisiweyo, kunye nokulungiswa kwepleyiti yomphezulu wegranite okufunekayo. Ngokunamathela kwinto yokuba ukunamathela ngokungqongqo kwimigangatho yobukhulu kuyinto eqhelekileyo kwipleyiti yomphezulu wegranite, iingcali zolawulo lomgangatho zikhusela ukuchaneka komlinganiselo ngamnye onegalelo ekugqibeleleni kwemveliso.
