I-Granite kudala yamkelwa njengeyona nto iphambili kwiziseko zoomatshini ngenxa yeempawu zayo ezikhethekileyo, kubandakanya ukuxinana okuphezulu, ukuqina, kunye nokuchasana nokwandiswa kwe-thermal. Ukuqonda iiparamitha zobugcisa kunye nemigangatho ehambelana neziseko zomatshini wegranite kubalulekile kwiinjineli kunye nabavelisi abaxhomekeke ekuchanekeni kunye nokuqina kwizicelo zabo.
Enye yezona parameters zobugcisa ezisisiseko zegranite mechanical bases ngamandla ayo acinezelayo, aqhele ukuvela kwi-100 ukuya kwi-300 MPa. La mandla aphezulu acinezelayo aqinisekisa ukuba igranite inokumelana nemithwalo ebalulekileyo ngaphandle kokuguqulwa, iyenze ilungele ukuxhasa oomatshini abanzima kunye nezixhobo. Ukongezelela, i-granite ibonisa i-coefficients ephantsi yokwandiswa kwe-thermal, ngokubanzi malunga ne-5 ukuya kwi-7 x 10 ^ -6 / °C, enciphisa utshintsho lwe-dimensional ngenxa yokuguquguquka kweqondo lokushisa, ukuqinisekisa ukusebenza okufanayo kwiindawo ezahlukeneyo.
Ukuthe tyaba komphezulu ngomnye umgangatho obalulekileyo kwiziseko zoomatshini begranite. Ukunyamezelwa kwe-flatness kudla ngokuchazwa kwii-micrometers, kunye nezicelo ezichanekileyo ezifuna ukunyamezela njenge-0.005 mm ngemitha nganye. Eli nqanaba lokuchaneka liyimfuneko kwizicelo ezifana nokulungelelanisa oomatshini bokulinganisa (i-CMMs) kunye nezixhobo ezibonakalayo, apho nokuba ukuphambuka okuncinci kunokukhokelela kwiimpazamo ezinkulu zokulinganisa.
Ngaphezu koko, ubuninzi begranite buqheleke ukusuka kwi-2.63 ukuya kwi-2.75 g/cm³, inegalelo kuzinzo lwayo kunye neempawu zokudambisa ukungcangcazela. Ezi mpawu zibalulekile ekunciphiseni impembelelo yokungcangcazela kwangaphandle, ngaloo ndlela kuphuculwa ukuchaneka kwezixhobo ezibuthathaka ezixhonywe kwiziseko zegranite.
Ukuqukumbela, iiparamitha zobugcisa kunye nemigangatho yeziseko zoomatshini zegranite zidlala indima ebalulekileyo kwisicelo sazo kuwo wonke amashishini ahlukeneyo. Ngokuthobela ezi nkcukacha, abavelisi banokuqinisekisa ukuthembeka kunye nokusebenza kwezixhobo zabo, ekugqibeleni kukhokelela ekuphuculeni ukusebenza kakuhle kunye nokuchaneka kweenkqubo zokuvelisa. Njengoko iteknoloji ihambela phambili, imfuno yomgangatho ophezulu weziseko zomatshini wegranite iya kuqhubeka ikhula, igxininisa ukubaluleka kokuqonda le migangatho yobugcisa.
