Kubunjineli bokuchaneka, ukuchaneka kwezixhobo zokulinganisa kumisela ukuthembeka kwenkqubo yonke yemveliso. Ngelixa izixhobo zokulinganisa zegranite nezeceramic zilawula ishishini elichaneke kakhulu namhlanje, izixhobo zokulinganisa zemabula zazisetyenziswa kakhulu kwaye zisasetyenziswa kwiindawo ezithile. Nangona kunjalo, ukuvelisa izixhobo zokulinganisa zemabula ezifanelekileyo kunzima kakhulu kunokusika nokupolisha amatye nje—imigangatho yobugcisa engqongqo kunye neemfuno zezinto kufuneka zilandelwe ukuqinisekisa ukuchaneka kokulinganisa kunye nokuzinza kwexesha elide.
Imfuneko yokuqala ikwindlela yokukhetha izinto. Ziintlobo ezithile zemabula yendalo kuphela ezinokusetyenziselwa izixhobo zokulinganisa. Ilitye kufuneka libe nesakhiwo esixineneyo, esilinganayo, esicolekileyo, kunye noxinzelelo oluncinci lwangaphakathi. Naziphi na iintanda, imithambo, okanye utshintsho lombala lunokubangela ukuguquka okanye ukungazinzi ngexesha lokusetyenziswa. Ngaphambi kokucubungula, iibhloko zemabula kufuneka zivuthwe ngononophelo kwaye zinciphise uxinzelelo ukuthintela ukugqwetheka kwesimo ngokuhamba kwexesha. Ngokungafaniyo nemabula yokuhombisa, imabula yokulinganisa kufuneka ihlangabezane neempawu zokusebenza zomzimba eziqinileyo, kubandakanya amandla oxinzelelo, ubulukhuni, kunye nokuxinana okuncinci.
Ukuziphatha kobushushu yenye into ebalulekileyo. I-marble inomlinganiselo ophezulu wokwanda kobushushu xa ithelekiswa ne-granite emnyama, nto leyo ethetha ukuba inovelwano ngakumbi kutshintsho lobushushu. Ke ngoko, ngexesha lokwenziwa nokulinganiswa, indawo yokusebenzela kufuneka igcine ubushushu kunye nokufuma okuzinzileyo ukuqinisekisa ukuchaneka. Izixhobo zokulinganisa i-marble zilungele ngcono iindawo ezilawulwayo ezifana neelabhoratri, apho utshintsho lobushushu oluphakathi luncinci.
Inkqubo yokuvelisa ifuna umgangatho ophezulu wobugcisa. Ipleyiti nganye yomphezulu wemabula, i-straightedge, okanye irula yesikwere kufuneka idlule kumanqanaba aliqela okusila okurhabaxa, ukusila okucolekileyo, kunye nokulepha ngesandla. Iingcali ezinamava zixhomekeke kwizixhobo zokuchukumisa kunye nokuchaneka ukuze zifikelele kwinqanaba le-micrometer flatness. Le nkqubo ijongwa kusetyenziswa izixhobo zokulinganisa eziphambili ezifana ne-laser interferometers, amanqanaba e-elektroniki, kunye ne-autocollimators. La manyathelo aqinisekisa ukuba ipleyiti nganye yomphezulu okanye irula ihambelana nemigangatho yamazwe ngamazwe efana ne-DIN 876, ASME B89, okanye i-GB/T.
Ukuhlolwa kunye nokulinganiswa yinxalenye ebalulekileyo yemveliso. Isixhobo ngasinye sokulinganisa imabula kufuneka sithelekiswe nemigangatho yesalathiso eqinisekisiweyo elandelwa yi-national metrology institutions. Iingxelo zokulinganisa ziqinisekisa ukuba isixhobo sithe tyaba, sithe tye, kwaye sinesikwere, ukuqinisekisa ukuba siyahlangabezana nemilinganiselo ethile. Ngaphandle kokulinganiswa okufanelekileyo, nomphezulu wemabula ocoliweyo kakuhle awunakuqinisekisa ukulinganiswa okuchanekileyo.
Nangona izixhobo zokulinganisa imabula zibonelela ngokugqitywa okugudileyo kwaye zifikeleleka ngexabiso eliphantsi, zikwanazo nemida. Ukuxinana kwazo kuzenza zibe sengozini yokufunxwa nokudaya umswakama, kwaye ukuzinza kwazo kungaphantsi kokwegranite emnyama enoxinano oluphezulu. Yingakho uninzi lwamashishini anamhlanje anokuchaneka okuphezulu—njengee-semiconductors, i-aerospace, kunye nokuhlolwa kwe-optical—ekhetha izixhobo zokulinganisa igranite. Kwi-ZHHIMG, sisebenzisa igranite emnyama ye-ZHHIMG®, enoxinano oluphezulu kunye nokusebenza ngcono komzimba kunegranite emnyama yaseYurophu okanye yaseMelika, enika ubulukhuni obuphezulu, ukumelana nokuguguleka, kunye nokuzinza kobushushu.
Nangona kunjalo, ukuqonda iimfuno ezingqongqo zokuveliswa kwezixhobo zokulinganisa imabula kunika ulwazi oluxabisekileyo malunga nophuhliso lwe-precision metrology. Inyathelo ngalinye—ukusuka ekukhetheni izinto eziluhlaza ukuya ekugqityweni nasekulinganisweni—limele ukuphishekela ukuchaneka okuchazwa lilonke ishishini lokuchaneka. Amava afunyenwe ekucutshungulweni kwemabula abeke isiseko setekhnoloji yokulinganisa i-granite kunye ne-ceramic yanamhlanje.
Apha kwi-ZHHIMG, sikholelwa ukuba ukuchaneka kokwenyani kuvela ekuqwalaseleni iinkcukacha ngokungagungqiyo. Nokuba sisebenza ngemabula, igranite, okanye iiceramics eziphambili, umsebenzi wethu uhlala ufana: ukukhuthaza uphuhliso lokuvelisa izinto ngendlela echanekileyo ngokusebenzisa ubuchule, ukuthembeka, kunye nobugcisa.
