Amapulatifomu okunemba kwe-granite aziwa ngokuqina kwawo nokuqina, okwenza abe abalulekile ekusetshenzisweni okunembe kakhulu emikhakheni efana ne-metrology kanye nobunjiniyela bemishini. Kodwa-ke, njengezinye izinto eziningi, i-granite ingakha lokho okwaziwa ngokuthi "ukucindezeleka kwangaphakathi" ngesikhathi senqubo yayo yokukhiqiza. Ukucindezeleka kwangaphakathi kubhekisela emandleni angaphakathi kwezinto ezivela ngenxa yokupholisa okungalingani, ukusatshalaliswa kwesisindo okungalingani, noma imiphumela yangaphandle phakathi nezigaba zokukhiqiza. Lokhu kucindezeleka kungaholela ekugobeni, ekuphazamisekeni, noma ngisho nasekuhlulekeni kwepulatifomu ye-granite ngokuhamba kwesikhathi uma kungaphathwanga kahle.
Ukuba khona kokucindezeleka kwangaphakathi ku-granite kuyinkinga evamile engafaka engcupheni ukunemba kanye nobude besikhathi samapulatifomu okunembile. Lokhu kucindezeleka kwenzeka lapho i-granite izwa ukupholisa okungalingani ngesikhathi senqubo yayo yokuqina noma lapho kukhona ukuhlukahluka kobuningi kanye nokwakheka kwezinto. Umphumela uba ukuthi i-granite ingabonisa ukuguquguquka okuncane kwangaphakathi, okungathinta ukuthamba kwayo, ukuzinza, kanye nobuqotho besakhiwo sonke. Ezisetshenzisweni ezibucayi kakhulu, ngisho nokuphambuka okuncane kakhulu kungaletha amaphutha okulinganisa futhi kuthinte ukusebenza kwesistimu yonke.
Ukuqeda ukucindezeleka kwangaphakathi ngesikhathi sokukhiqiza kubalulekile ekuqinisekiseni ukunemba okuphezulu nokuthembeka kwamapulatifomu e-granite. Enye yezindlela eziphumelela kakhulu ezisetshenziswa ekukhiqizeni amapulatifomu okunemba kwe-granite inqubo ebizwa ngokuthi “ukukhululeka ekucindezelekeni” noma “ukuncibilikisa.” Ukuncibilikisa kuhilela ukufudumeza i-granite ngokucophelela ekushiseni okuthile bese uyivumela ukuthi iphole kancane endaweni elawulwayo. Le nqubo isiza ukukhulula ukucindezeleka kwangaphakathi okungenzeka ukuthi kwakheke ngesikhathi sokusika, ukubumba, kanye nokupholisa kwezigaba zokukhiqiza. Inqubo yokupholisa kancane ivumela izinto ukuthi zizinze, zinciphise ingozi yokuguquka futhi zithuthukise amandla ayo kanye nokufana kwayo.
Ngaphezu kwalokho, ukusetshenziswa kwe-granite esezingeni eliphezulu, elinganayo kusiza ukunciphisa ukucindezeleka kwangaphakathi kusukela ekuqaleni. Ngokuthola izinto ezinokwakheka okufanayo kanye namaphutha amancane emvelo, abakhiqizi banganciphisa amathuba okugcwala kokucindezeleka okungase kuthinte ukusebenza kwepulatifomu yokunemba kamuva.
Esinye isinyathelo esibalulekile ekunciphiseni ukucindezeleka ukucutshungulwa nokupholishwa kwe-granite ngokucophelela ngesikhathi senqubo yokukhiqiza. Ngokuqinisekisa ukuthi i-granite icutshungulwa ngokunemba nangokucophelela, amathuba okufaka ukucindezeleka okusha ayancishiswa. Ngaphezu kwalokho, ezigabeni zokugcina zokukhiqiza, amapulatifomu avame ukuhlolwa ngokulawula ikhwalithi okuhlanganisa ukulinganisa ukuthamba nokuhlola noma yiziphi izimpawu zokuphambuka okubangelwa ukucindezeleka kwangaphakathi.
Ekuphetheni, yize amapulatifomu okunemba kwe-granite engathuthukisa ukucindezeleka kwangaphakathi ngesikhathi sokukhiqiza, izindlela ezisebenzayo ezifana nokufaka i-anneal, ukukhethwa kwezinto ngokucophelela, kanye nomshini oqondile kunganciphisa noma kuqede lokhu kucindezeleka kakhulu. Ngokwenza kanjalo, abakhiqizi baqinisekisa ukuthi amapulatifomu agcina ukuzinza kwawo okulinganiselwe, ukunemba, kanye nokuthembeka kwesikhathi eside, okubaluleke kakhulu ekusetshenzisweni kwezimboni okunembile kakhulu. Ngokuqonda nokubhekana nokucindezeleka kwangaphakathi, amapulatifomu okunemba kwe-granite angaqhubeka nokuhlangabezana nezidingo eziqinile zezimboni ezithembele kuzo ekulinganisweni okunembile kanye nokusebenza okuphezulu.
Ukuqeda ukucindezeleka kwangaphakathi akuyona nje indaba yokuthuthukisa ukusebenza kwepulatifomu kodwa futhi nokuvikela isikhathi eside nokuqina kwemishini encike kulezi zingxenyekazi ukuze kutholakale imiphumela enembile.
