Uma uke wahamba endaweni yokukhiqiza ngokunemba, ilabhorethri yokulinganisa, noma igumbi lokulawula ikhwalithi yendiza, kungenzeka ukuthi uke wabona ipuleti lobuso be-granite lisebenza. Lawa matshe aqinile, amnyama enziwe ngamatshe emvelo ahlala enhliziyweni ye-metrology enobukhulu, esebenza njengesisekelo senkomba lapho kuthathwa khona izilinganiso ezingenakubalwa nsuku zonke. Amageyiji okuphakama ahlala kuwo. Izinkomba zokushintshana ziqhathanisa ukufundwa kwazo. Imishini yokulinganisa ehlanganisiwe iwasebenzisa njengezindawo ze-datum. Ezimbonini lapho i-micron yephutha ingasho umehluko phakathi kwengxenye yendiza ephumelelayo kanye nokwehluleka, ipuleti lobuso be-granite aliyona into engaphansi "kwe-datum yeqiniso."
Noma kunjalo, naphezu kokubaluleka kwawo, amapuleti ongaphezulu e-granite ahlala eyimfihlakalo kubathengi abaningi ngisho nakwabanye onjiniyela abawasebenzisa nsuku zonke. Enye yemithombo evame kakhulu yokudideka uhlelo lokulinganisa. Lisho ukuthini ngempela iBanga 00? Lihluke kanjani kwiBanga 0 noma iBanga 1? Kufanele ukhethe nini elinye kunelinye? Ingabe ibanga eliphakeme lihlala lingcono? Lena yimibuzo ehlelwe yilesi sihloko ukuyiphendula ngolimi olulula nolusebenzayo.
Ukulinganisa ngokunemba kuyindlela yokulawula ukungaqiniseki. Njalo lapho uchwepheshe ebeka igeyiji epuletini lobuso futhi eqopha ukufundwa, lokho kufundwa kuthembeke kuphela njengobuso obubhekiselwe ngaphansi kwalo. Uma ipuleti ngokwayo iphambuka endizeni ephelele ngama-micron amaningana, lawo ma-micron anezela ngqo ekungaqinisekini kokulinganisa. Ezweni lapho ukubekezelelana kwemishini yanamuhla kuvame ukudinga ukunemba kwe-micron yenombolo eyodwa, ipuleti lobuso "eliseduze ngokwanele" lingase lingasasondele ngokwanele nhlobo.
Yilapho amamaki okunemba angena khona engqondweni. Amamaki okunemba empeleni ayindlela yokuhlela ekutshela ukuphambuka okuphezulu okuvunyelwe kusukela ekusibekeni kwepuleti elingaphezulu elinikeziwe, ngokusekelwe kusayizi walo kanye nokusetshenziswa okuhlosiwe. Amamaki awanqunyelwe; achazwa yizindinganiso eziqashelwa emhlabeni wonke ezichaza amanani aqondile okubekezelela, izindlela zokuhlola, kanye nezidingo zezinto ezibonakalayo. Ukuqonda la mamaki kubalulekile kunoma ngubani onesibopho sokukhetha imishini yokulinganisa, ukuklama izinqubo zokulawula ikhwalithi, noma ukuqinisekisa ukuhambisana nemithethonqubo yemboni.
Indinganiso yamazwe ngamazwe ebhekiselwa kakhulu kumapuleti obuso be-granite yi-ISO 8512-2, enesihloko esithi “Amapuleti Obuso — Ingxenye 2: I-Granite.” Eshicilelwe yi-International Organisation for Standardization, le ndinganiso ichaza izidingo zamapuleti obuso be-granite angunxande noma ayisikwele asukela ku-160 mm ngo-100 mm kuya ku-2500 mm ngo-1600 mm. Isungula amazinga amane okunemba: Ibanga 0, Ibanga 1, Ibanga 2, kanye neBanga 3, lapho iBanga 0 limelela ukunemba okuphezulu kakhulu kanye neBanga 3 limelela ukubekezelelana okukhulu kakhulu.
Ngesikhathi esifanayo, i-DIN 876 ejwayelekile yaseJalimane isebenzisa uphawu oluhlukile kancane olufaka iBanga 00 ngaphezu kweBanga 0. Lolu hlelo luvame kulo lonke elaseYurophu nase-Asia, lapho abakhiqizi bevame ukucacisa amapuleti njengeBanga 00, 0, 1, noma 2. Ukuqokwa kweBanga 00 kumelela ukubekezelelana okuqinile kuneBanga 0, kusondela ezingeni lokunemba okudingekayo emalabhorethri okulinganisa okuqala lapho kugcinwa khona amazinga okulinganisa kazwelonke.
Ngaphesheya kwe-Atlantic, imakethe yaseMelika ibilokhu ithembele ku-Federal Specification GGG-P-463c kanye nomlandeli wayo, i-ASME B89.3.7-2013. Le mibhalo ichaza amamaki amathathu aqokwe njenge-AA, A, kanye ne-B, lapho iBanga le-AA liyindinganiso yelabhorethri, iBanga A liyindinganiso yokuhlola, kanti iBanga B liyigumbi lamathuluzi noma indinganiso yesitolo. Ngokwemibandela engokoqobo, iBanga le-AA lihambisana eduze neBanga le-00 ngaphansi kwe-DIN, iBanga A lihambisana neBanga le-0, kanye neBanga le-B lihambisana neBanga le-1. Ngenkathi amanani okubekezelelana aqondile angase ahluke kancane ngenxa yokuguqulwa kwamayunithi kanye nokuzungeza, ukuhlelwa komqondo kuyavumelana kuzo zonke izindinganiso ezinkulu.
Ngaphambi kokucwila ezigabeni ezithile, kubalulekile ukuqonda ukuthi ukunemba kwepuleti lobuso kuhilela izici ezimbili ezihlukene kodwa ezibaluleke ngokulinganayo. Esokuqala ukuthamba okuphelele, okubhekisela ekuphambukeni okuphezulu kusuka endizeni ephelele kuyo yonke indawo yokusebenza. Esesibili ukuhluka kwendawo kokuthamba, ngezinye izikhathi okubizwa ngokuthi ukufundwa okuphindaphindiwe.
