Izinkundla zokunemba zegwadle zaziwa ngokuzinza nokuqina kwazo, okuzenza zibaluleke kakhulu ekusetshenzisweni okunemba okuphezulu emikhakheni efana ne-metrology kanye nobunjiniyela bemishini. Kodwa-ke, njengezinye izinto eziningi, i-granite ingathuthukisa lokho okwaziwa ngokuthi "ukucindezeleka kwangaphakathi" phakathi nenqubo yokukhiqiza. Ingcindezi yangaphakathi isho amandla angaphakathi kokubalulekile avela ngenxa yokupholisa okungalingani, ukusatshalaliswa kwesisindo esingalingani, noma imithelela yangaphandle phakathi nezigaba zokukhiqiza. Lokhu kucindezeleka kungaholela ekuphendukeni, ukuhlanekezela, noma ngisho nokwehluleka kweplatifomu yegwadle ngokuhamba kwesikhathi uma ingalawulwa kahle.
Ukuba khona kokucindezeleka kwangaphakathi ku-granite kuyinkinga evamile engafaka engozini ukunemba nokuphila isikhathi eside kwamapulatifomu anembayo. Lokhu kucindezeleka kwenzeka lapho igwadle liba nokupholisa okungalingani phakathi nenqubo yokuqiniswa noma uma kunokuhlukahluka kokuminyana nokwakheka kwezinto. Umphumela uba ukuthi igwadle lingase libonise ukuwohloka okuncane kwangaphakathi, okungase kuthinte ukucaba kwayo, ukuzinza, kanye nobuqotho besakhiwo ngokuphelele. Kuzinhlelo zokusebenza ezizwela kakhulu, ngisho nokuhlanekezela okuncane kakhulu kungathula amaphutha okulinganisa futhi kuthinte ukusebenza kwesistimu yonke.
Ukuqeda ukucindezeleka kwangaphakathi ngesikhathi sokukhiqiza kubalulekile ukuze kuqinisekiswe ukunemba okuphezulu nokuthembeka kwamapulatifomu egwadle. Enye yezindlela eziphumelela kakhulu ezisetshenziswa ekukhiqizeni izinkundla ezinembayo zegwadle inqubo ebizwa ngokuthi “i-stress relief” noma “i-annealing.” Ukufaka i-annealing kuhilela ukushisisa ngokucophelela igwagwa kumazinga okushisa athile bese uyivumela ukuthi iphole kancane endaweni elawulwayo. Le nqubo isiza ukukhulula izingcindezi zangaphakathi okungenzeka ukuthi zakheke ngesikhathi sokusika, ukulolonga, kanye nezigaba zokupholisa zokukhiqiza. Inqubo yokupholisa kancane ivumela izinto ukuthi zizinze, zinciphise ubungozi bokuguquguquka futhi zithuthukise amandla ayo kanye nokufana kwawo.
Ukwengeza, ukusetshenziswa kwe-granite yekhwalithi ephezulu, e-homogeneous kusiza ukunciphisa ukucindezeleka kwangaphakathi kusukela ekuqaleni. Ngokuthola izinto ezinokwakheka okungaguquki kanye namaphutha emvelo amancane, abakhiqizi banganciphisa amathuba okugxilisa ingcindezi okungase kuthikameze ukusebenza kwenkundla enembayo.
Esinye isinyathelo esibalulekile ekunciphiseni ingcindezi ukukhanda ngokucophelela nokupholishwa kwegwadle phakathi nenqubo yokukhiqiza. Ngokuqinisekisa ukuthi i-granite icutshungulwa ngokunemba nangokucophelela, amathuba okwethula izingcindezi ezintsha ayancishiswa. Ngaphezu kwalokho, phakathi nezigaba zokugcina zokukhiqiza, amapulatifomu ngokuvamile abhekana nokuhlolwa kokulawulwa kwekhwalithi okuhlanganisa ukulinganisa ukucaba kanye nokuhlola noma yiziphi izimpawu zokuhlanekezela okubangelwa ukucindezeleka kwangaphakathi.
Sengiphetha, nakuba amapulatifomu anemba egwadule angathuthukisa ingcindezi yangaphakathi ngesikhathi sokukhiqiza, izindlela ezisebenzayo ezinjengokuhlanganisa, ukukhetha izinto ngokucophelela, kanye nomshini onembile kunganciphisa kakhulu noma kuqede lezi zingcindezi. Ngokwenza kanjalo, abakhiqizi baqinisekisa ukuthi amapulatifomu agcina ukuzinza kwawo kobukhulu, ukunemba, nokuthembeka kwesikhathi eside, okubalulekile ekusetshenzisweni kwezimboni okunembayo okuphezulu. Ngokuqonda nokubhekana nengcindezi yangaphakathi, izinkundla zokunemba zegwadle zingaqhubeka nokuhlangabezana nezidingo eziqinile zezimboni ezithembele kuzo ukuze zilinganiswe ngokunemba kanye nokusebenza kokusebenza okuphezulu.
Ukuqeda ingcindezi yangaphakathi akuyona nje indaba yokuthuthukisa ukusebenza kwenkundla kodwa futhi nokuvikela ukuphila isikhathi eside nokuqina kwezisetshenziswa ezincike kulezi zingxenyekazi ukuze uthole imiphumela enembile.
