Izixhobo zegranite mechanical zisetyenziswa kakhulu kwiimveliso zezixhobo zokucubungula ngokuchanekileyo ngenxa yeempawu zazo ezintle ezifana nokuqina okuphezulu, ukwanda okuphantsi kobushushu, kunye nomthamo ogqwesileyo wokudambisa. Nangona kunjalo, njengazo zonke ezinye izixhobo, azigqibelelanga kwaye zinokuba neziphene ezithile ekufuneka ziqwalaselwe xa kusetyenzwa ngokuchanekileyo.
Esinye seziphene ezibonwa rhoqo kwiindawo zegranite kukuvela kokuqhekeka okanye ukuqhekeka kumphezulu. Ezi ziphene zinokubangelwa zizinto ezininzi ezifana nokugqithisa kakhulu, ukufakwa okungafanelekanga, uxinzelelo lobushushu, okanye ukuvezwa kwindawo engqongileyo enzima. Ukuthintela oku, iindawo kufuneka zenziwe ngejometri efanelekileyo kunye nobukhulu bodonga, kwaye kufuneka kuthathwe amanyathelo afanelekileyo ukuthintela ukugqithiswa kakhulu okanye uxinzelelo lobushushu.
Esinye isiphene esinokubakho kwizixhobo zegranite kukwakheka kweembobo kunye neembobo kumphezulu okanye ngaphakathi kwezinto ngokwazo. Ezi ziphene zinokwenza buthathaka isakhiwo kwaye ziphazamise ukuchaneka kwemveliso yokugqibela. Ukukhetha ngononophelo kunye nokuhlolwa kwezinto ezikrwada, kunye neenkqubo ezifanelekileyo zokunyanga kunokuthintela ukwakheka kweembobo kunye neembobo kwizixhobo zegranite.
Ukongeza, izinto zegranite zinokubonisa utshintsho kwindlela umphezulu othe tyaba ngayo okanye indlela ubuso obume ngayo xa buthelekiswa. Olu tshintsho lunokuvela kutshintsho lwendalo lwezinto, kunye nenkqubo yokuvelisa. Ukuqinisekisa ukuchaneka kwemveliso yokugqibela, olu tshintsho kufuneka lulinganiswe ngononophelo kwaye luhlawulwe ngexesha lenkqubo yokugaya.
Esinye isiphene esinokubakho kwizixhobo zegranite kukwahluka kwi-thermal expansion coefficients kuzo zonke izinto. Oku kunokubangela ukungazinzi kobukhulu kunye nokuchaneka okunciphileyo kumanqanaba obushushu. Ukunciphisa esi siphumo, iinjineli zinokuyila izixhobo ukunciphisa ukuphambuka kobushushu, okanye abavelisi banokusebenzisa unyango lobushushu ukuze bafumane i-thermal expansion coefficient efanayo kuzo zonke izinto.
Lilonke, izinto zegranite zizinto ezibalaseleyo zokulungisa ngokuchanekileyo iimveliso zezixhobo, kodwa zinokuba neziphene ezinokuthi zifune ukuqwalaselwa ngononophelo nokulawulwa. Ngokuqonda ezi ziphene kunye nokuthatha amanyathelo afanelekileyo okuthintela okanye ukunciphisa, abavelisi banokuvelisa izinto ezikumgangatho ophezulu ezihlangabezana neemfuno ezichanekileyo zemizi-mveliso yanamhlanje.
