Amathuluzi Okulinganisa Ngokucophelela Kwegranite: Ama-Calipers, Ama-Height Gauges, kanye Nezikwele Zokulawula Ikhwalithi

Ezweni eliqondile lokukhiqiza nokulawula ikhwalithi, ukunemba akuyona nje umgomo kodwa kuyinto edingekayo ngokuphelele. Ikhono lokulinganisa ngokunembile nokuqinisekisa ubukhulu liyisisekelo sokuqinisekisa ubuqotho bomkhiqizo, ukushintshaniswa, kanye nokunamathela ezindinganisweni eziqinile zemboni. Ngenkathi izinto ezahlukahlukene zisetshenziswe ekwakhiweni kwezinsimbi zokulinganisa, i-granite iye yavela kancane kancane njengento ekhethwayo yamathuluzi anokunemba okuphezulu njengezikwele ezinkulu, izitendi zokulinganisa ukuphakama, kanye namapuleti obuso. Izakhiwo zayo zomzimba ezingokwemvelo zinikeza isisekelo esingenakuqhathaniswa se-metrology, okwenza abakhiqizi bakwazi ukufeza nokugcina ukubekezelelana okuqinile okudingekayo ezisetshenzisweni zezimboni zanamuhla.

Ukwamukelwa kabanzi kwe-Granite kumathuluzi okulinganisa ngokunemba akuyona into eyenzeka ngengozi; kuvela enhlanganisela eyingqayizivele yezakhiwo zangaphakathi ezibhekana ngqo nezidingo ezibalulekile zokulinganisa okunembile. Lezi zakhiwo zihlangene zinegalelo ekusebenzeni okuphezulu kanye nobude besikhathi sezinsimbi ezisekelwe ku-granite.

Enye yezinzuzo ezibaluleke kakhulu ze-granite ku-metrology ukuzinza kwayo okuphawulekayo kobukhulu, ikakhulukazi i-coefficient yayo ephansi kakhulu yokwanda kokushisa (i-CTE). Ngokungafani nezinto zensimbi, ezikhula futhi zinciphe ngokuphawulekayo ngokushintshashintsha kwezinga lokushisa, i-granite ibonisa ushintsho oluncane ngobukhulu. Lesi sici sibalulekile ezindaweni lapho izinga lokushisa elizungezile lingenakulawulwa ngokuphelele, njengoba liqinisekisa ukuthi ithuluzi lokulinganisa ngokwalo lihlala lihambisana nobukhulu. Isibonelo, i-CTE ye-granite iphansi kakhulu kuneyensimbi noma insimbi ephonswe, okusho ukuthi amathuluzi okulinganisa i-granite agcina ukunemba kwawo phezu kwezimo ezibanzi zokushisa. Lokhu kuzinza kokushisa okungokwemvelo kubaluleke kakhulu ekulinganisweni okuthembekile, njengoba ukuguquguquka okubangelwa izinga lokushisa emishinini yokulinganisa kungaletha amaphutha amakhulu, kubeke engcupheni ubuqotho bezinqubo zokulawula ikhwalithi.

Izilinganiso zokunemba zisengozini enkulu yokudlidliza kwangaphandle, okungabangela ukunyakaza okuncane entweni yokulinganisa noma emsebenzini, okuholela ekufundweni okungalungile. I-Granite inezici ezinhle kakhulu zokudlidliza kwemvelo, idlula kakhulu ezensimbi ezifana nensimbi ephonswe ngensimbi. Isakhiwo sayo esiminyene, esikristalu simunca futhi sichithe ngempumelelo ukudlidliza komshini, sikuvimbela ekuphazamiseni inqubo yokulinganisa. Leli khono lokudlidliza elingasebenzi libaluleke kakhulu ezindaweni zezimboni lapho ukusebenza kwemishini kungadala ukudlidliza okuphansi okuqhubekayo. Ngokunciphisa umthelela walokhu kuphazamiseka, amathuluzi okulinganisa i-granite ahlinzeka ngendiza yokubhekisela ezinzile nethembekile, enegalelo ekuphindaphindweni okuphezulu kokulinganisa nokunemba.

I-Granite iyinto eqinile kakhulu futhi engagugi, ngokuvamile inobunzima be-Mohs obungu-6 kuya ku-7. Lesi sici sivumela amathuluzi okulinganisa i-granite ukuthi amelane nokusetshenziswa njalo kanye nokuxhumana okuphindaphindiwe nezinsimbi zokusebenza ngaphandle kokuguguleka okukhulu noma ukuwohloka kobuso bazo obunembile. Ukuqina kwe-granite kuqinisekisa ukuthi ukunemba kwamathuluzi kugcinwa isikhathi eside, kunciphisa isidingo sokulungiswa kabusha noma ukushintshwa njalo. Ngaphezu kwalokho, i-granite ayinamakhemikhali, okusho ukuthi imelana nokugqwala, ukugqwala, kanye nokufakwa kwe-magnetization. Ngokungafani nensimbi ephonswe, edinga ukugcotshwa njalo nokugcinwa ukuze kuvinjelwe ukugqwala, amathuluzi e-granite cishe awadingi ukunakekelwa kulokhu. Lokhu kumelana nezici zemvelo kwenza i-granite ibe yinto efanelekile yokusetshenziswa ezindaweni ezahlukahlukene zezimboni, kufaka phakathi lezo ezinomswakama ophezulu noma ukuchayeka kuma-coolant ahlukahlukene kanye nama-lubricant. Ukungabikho kokugqwala kuqeda nengozi yokudlulisela izinhlayiya ezigqwalayo ezingcezwini zomsebenzi ezithambile, okuthuthukisa kakhulu ukufaneleka kwayo ekulawulweni kwekhwalithi.

Izakhiwo ezinhle zeGranite ziholele ekusetshenzisweni kwayo kumathuluzi ahlukahlukene okulinganisa ukunemba abalulekile, ngalinye lidlala indima ebalulekile ekuqinisekiseni ikhwalithi nokunemba kwezingxenye ezikhiqiziwe.

Izikwele ze-Granite master ziyithuluzi eliyisisekelo lokubhekisela elisetshenziselwa ukuhlola ngokunembile ubunjalo, ukufana, kanye nokuqondakala kwezimbazo zamathuluzi omshini (X, Y, kanye no-Z) kanye ne-Coordinate Measuring Machines (CMMs). Lawa mathuluzi abonakala ngokuqina kwawo okumangalisayo, okunikeza ireferensi ephelele yobunjalo. Ngokuvamile, izikwele ze-master zinezinhlangothi ezinhlanu eziqediwe (ubuso obukhulu obubodwa kanye nemiphetho emine) eziqondile ukuze zibe ziyisicaba, ziyisikwele, futhi zilingane. Zitholakala ngamamaki ahlukahlukene, njenge-laboratory grade AA (isb., 0.000025” ngo-6”) noma ibanga lokuhlola A (isb., 0.000050” ngo-6”), kuye ngezinga elidingekayo lokunembile. Ukuzinza okungokwemvelo kwe-granite kuqinisekisa ukuthi lezi zikwele zigcina ukunemba kwazo kwejometri ngokuhamba kwesikhathi, okwenza zibe yinto ebalulekile ekulinganiseni nasekuqinisekiseni ukuhambisana kwemishini ebalulekile.

Nakuba ama-caliper evame ukuphathwa ngesandla, ama-height gauge adinga indawo eqondile neqondile yokubhekisela ukuqinisekisa ukulinganisa okuqondile okuqondile. Ama-granite height gauge ahlinzeka ngalokhu kuzinza okubalulekile. Lawa ma-stand aklanyelwe ukuba makhulu futhi aqine, anciphise noma yikuphi ukuphambuka noma ukudlidliza okungathinta ukulinganisa. Ubuso obuyisicaba nobuzinzile be-granite stand buqinisekisa ukuthi i-height gauge isebenza kusukela ku-datum yangempela, okuvumela ukunqunywa okunembile kokuphakama, ukujula, kanye nezinyathelo. Ukuqina kokushisa kwe-granite kuvimbela futhi i-stand ngokwayo ukuthi ikhule noma inciphe, okungenjalo okungafaka amaphutha ekulinganisweni kokuphakama. Lokhu kwenza ama-granite height gauge abe yingxenye ebalulekile kuma-laboratories okulawula ikhwalithi kanye nasesitolo sokuqinisekisa ubukhulu bezingxenye.

Nakuba kungashiwongo ngokucacile esihlokweni, amapuleti obuso be-granite ayisici esiyisisekelo lapho kwenziwa khona izilinganiso eziningi zokunemba, okuhlanganisa nalezo ezinezilinganiso zokuphakama nezikwele. Asebenza njengendawo eyinhloko yokubhekisela emisebenzini yokuhlola nokubeka. Ipuleti lobuso be-granite lenzelwe ukuba liqine, likhulu, futhi lisicaba kakhulu, linikeze indawo ezinzile, elinganayo engaphambuki ngaphansi komthwalo. Ubulukhuni be-granite bukhawulela ukuguguleka, okuqinisekisa ukuthi ipuleti ligcina lisicaba eminyakeni eminingi yokusetshenziswa. Ukunemba kwepuleti lobuso kubalulekile, futhi ngokuvamile akhiqizwa ukuze adlule imininingwane kahulumeni njenge-ASME B89.3.7, lapho ukucaba nokufundwa okuphindaphindiwe kubaluleke kakhulu. Ukulinganiswa njalo kwala mapuleti kubalulekile ukuze kugcinwe ukunemba kwawo, kuqinisekiswe ukuthi zonke izilinganiso ezithathwe kuwo zinembile futhi zithembekile.

Ukudalwa kwamathuluzi okulinganisa ukunemba kwe-granite kuhilela inqubo yokukhiqiza eyinkimbinkimbi eguqula i-granite eluhlaza ibe amathuluzi okunemba okungavamile. Le nqubo ifana naleyo yezingxenye zomshini we-granite kodwa igcizelela kakhulu ukuqeda ubuso kanye nokunemba kwe-geometric.
