Izixhobo zokulinganisa ngokuchanekileyo igranite (iirula zesikwere, ii-straightedges, ii-Angle rulers, njl.njl.) zidlala indima ebalulekileyo kwiindawo ezininzi eziphezulu ngenxa yokuchaneka kwazo okuphezulu, ukuzinza okuphezulu kunye nokumelana nokugqwala okunamandla.
Kwinkqubo yokulungisa ngoomatshini ngokuchanekileyo, isetyenziselwa ukulinganisa ukuthe tye kweereyile zesikhokelo kunye nokuthamba kweetafile zokusebenza kwizixhobo zoomatshini be-CNC, amaziko oomatshini kunye nezinye izixhobo. Ngomlinganiselo wokwandiswa kobushushu ophantsi njenge (4-8) × 10⁻⁶/℃, inokumelana nempembelelo yokunyuka kobushushu ngexesha lokusebenza kwezixhobo zoomatshini. Xa ihlola iindawo ezichanekileyo, umphezulu wayo ophantsi orhabaxa awuyi kukrwela umsebenzi kwaye ayimelani nokugqwala kweoyile.
Amashishini eenqwelo moya kunye nokhuselo aneemfuno ezingqongqo zokuchaneka. Izixhobo zokulinganisa i-granite zisetyenziselwa ukulinganisa izixhobo ze-tenon zeebhleyidi zeenjini zeenqwelo moya kunye nokuhlola iindawo zokudibana kweekhabhini zee-missile, njl. Iimpawu zayo zokudambisa okuphezulu zinokufunxa ukungcangcazela kwindawo yokusebenzela. Izinzile kakhulu kwiikhemikhali kwaye inokuziqhelanisa nendawo ekhethekileyo yenkqubo yendawo yokusebenzela yeenqwelo moya, iqinisekisa ukuchaneka kokwenziwa kwezinto ezibalulekileyo.
Kwicandelo lokwenziwa kwezixhobo ze-elektroniki kunye ne-semiconductor, izixhobo zokulinganisa i-granite zisetyenziselwa ukulinganisa iireli zesikhokelo kwizixhobo ezifana noomatshini be-photolithography kunye noomatshini bokuqhekeza i-wafer, kunye nokuhlolwa kwezinto zokupakisha iitships. Uphawu lwayo lokungabikho kwe-ion yesinyithi luthintela ukungcolisa indawo yokusebenzela ecocekileyo ye-semiconductor, ukuqinisekisa ukuchaneka kwe-lithography yesikali esincinci kunye nomgangatho we-SMT patch soldering.
Amaziko ovavanyo lweMetrology kunye nophando asebenzisa izixhobo zokulinganisa igranite njengemilinganiselo yokulinganisa ezinye izixhobo zokulinganisa zesinyithi. Zinokugcinwa okugqwesileyo kokuchaneka kwexesha elide, kwaye utshintsho lokuthamba emva kweminyaka eli-10 yokusetyenziswa yi-≤±0.5μm/m. Ikwasetyenziswa rhoqo njengesalathiso sokulinganisa okuchanekileyo kwisayensi yezinto kunye novavanyo lobunjineli be-optical.
Ukongeza, izixhobo zokulinganisa igranite zikwasetyenziswa ekwenzeni izixhobo zonyango kunye nezixhobo zokukhanya, ezinje ngokulinganisa amalungu eerobhothi zotyando kunye neziseko zeebrackets zeteleskopu yeenkwenkwezi, ukuqinisekisa ukuba izixhobo zifikelela kubuchule bokubeka indawo obungaphantsi kwemilimitha kunye neziphumo zokujonga ngaphandle kokuphazamiseka. Ngokusebenza okugqwesileyo, izixhobo zokulinganisa ngokuchanekileyo igranite ziye zaba "lilitye lembombo elichanekileyo" lemveliso ephezulu.
