Amathuluzi okulinganisa ukunemba kwe-granite (ama-ruler asikwele, ama-straightedge, ama-Angle ruler, njll.) adlala indima ebalulekile emikhakheni eminingi ephezulu ngenxa yokunemba kwawo okuphezulu, ukuzinza okuphezulu kanye nokumelana nokugqwala okunamandla.
Ekucutshungulweni kwemishini okunembile, isetshenziselwa ukulinganisa ukuqondile kwemigqa yokuqondisa kanye nokuba sicaba kwamatafula okusebenza kumathuluzi omshini we-CNC, izikhungo zomshini wokugaya kanye neminye imishini. Njengoba ine-coefficient yokwandisa ukushisa ephansi njenge-(4-8) ×10⁻⁶/℃, ingamelana nethonya lokwenyuka kwezinga lokushisa ngesikhathi sokusebenza kwamathuluzi omshini. Lapho ihlola izingxenye zokunembile, ubuso bayo obuphansi ngeke buklwebhe ingxenye yokusebenza futhi imelana nokugqwala kwamafutha.
Izimboni zezindiza nezokuvikela zinezidingo eziqinile zokunemba. Amathuluzi okulinganisa i-granite asetshenziselwa ukulinganisa izinto ezihlanganisiwe ze-tenon zezinsika zenjini yezindiza nokuhlola izindawo zokuhlangana zezindawo zokubopha zemishini ye-missile, njll. Isici sayo sokunciphisa kakhulu singamunca ukudlidliza endaweni yokusebenzela. Iqinile futhi ingazivumelanisa nesimo senqubo ekhethekile yendawo yokusebenzela yezindiza, iqinisekise ukunemba kokukhiqiza kwezingxenye ezibalulekile.
Emkhakheni wokukhiqiza izinto ze-elekthronikhi neze-semiconductor, amathuluzi okulinganisa i-granite asetshenziselwa ukulinganisa imigqa yokuqondisa emishinini efana nemishini ye-photolithography kanye nemishini yokusika i-wafer, kanye nokuhlola izinto zokupakisha ze-chip. Isici sayo sokungabi namvula ye-ion yensimbi sigwema ukungcolisa indawo yokusebenzela ehlanzekile ye-semiconductor, okuqinisekisa ukunemba kwe-lithography yesikali esincane kanye nekhwalithi ye-SMT patch soldering.
Izikhungo zokuhlola nokucwaninga nge-Metrology zisebenzisa amathuluzi okulinganisa i-granite njengezilinganiso zokulinganisa amanye amathuluzi okulinganisa insimbi. Ane-retention enhle kakhulu yesikhathi eside, futhi ushintsho lwesicaba ngemva kweminyaka eyi-10 yokusetshenziswa luyi-≤±0.5μm/m. Ivame ukusetshenziswa njengereferensi yokulinganisa enembile kakhulu kwisayensi yezinto zokwakha kanye nokuhlolwa kobunjiniyela bokukhanya.
Ngaphezu kwalokho, amathuluzi okulinganisa i-granite nawo asetshenziswa ekukhiqizweni kwamadivayisi ezokwelapha kanye namathuluzi okukhanya, njengokulinganisa amalunga amarobhothi okuhlinza kanye nezisekelo zama-brackets e-astronomical telescope, ukuqinisekisa ukuthi imishini ifinyelela ukunemba kokubeka okungaphansi kwamamilimitha kanye nemiphumela yokubuka engenaphutha. Ngokusebenza okuvelele, amathuluzi okulinganisa ukunemba kwe-granite abe "yitshe legumbi eliqondile" lokukhiqiza okuphezulu.
