Okokuqala, iingenelo zesiseko segranite
1. Ukuqina okuphezulu kunye nozinzo
I-Granite inoxinano oluphezulu (2.6-3.1g /cm³), kwaye i-modulus kaYoung (i-modulus ye-elastic) inokufikelela kwi-50-100 GPa, iphezulu kakhulu kunentsimbi eqhelekileyo (malunga ne-200 GPa), kodwa ngenxa yesakhiwo sayo sekristale ye-isotropic, phantse ayinayo i-deformation yeplastiki xa isetyenziswa ixesha elide. Xa ithelekiswa nezinto zesinyithi, i-granite thermal expansion coefficient iphantsi kakhulu (malunga ne-5×10⁻⁶/℃), kwindawo yokuguquguquka kobushushu isenokugcina uzinzo oluhle kakhulu, kuthintelwe ukuba ukucotha kokubanda ngenxa yokwanda kobushushu kuchaphazele ukuchaneka kwezixhobo.
2. Ukusebenza kakuhle kokunciphisa ukungcangcazela
Isakhiwo sangaphakathi sekristale segranite sinomswakama ophezulu wangaphakathi, onokufunxa ngempumelelo ukungcangcazela okuphindaphindekayo kwaye unciphise i-resonance phenomenon. Xa kuthelekiswa nesiseko sesinyithi, igranite inomthamo wokunciphisa ukungcangcazela onamandla kuluhlu lwe-20Hz-1kHz, ibonelela ngendawo yokuqala "ecocekileyo" ngakumbi kwinkqubo yokwahlula ukungcangcazela okusebenzayo kunye nokunciphisa umthwalo wolawulo olusebenzayo olulandelayo.
3. Ukumelana nokugqwala, okungekho magnethi, ukusetyenziswa ngokubanzi
Uzinzo lweekhemikhali zegranite, ukumelana ne-asidi kunye nokugqwala kwe-alkali, aziyi kugqwala okanye ukubola, zilungele igumbi elicocekileyo, ukufuma okuphezulu okanye indawo egqwalisayo. Ukongeza, igranite yinto engenamagnethi, ayizukuphazamisana nezixhobo ezichanekileyo (ezifana ne-electron microscopy, izixhobo zokulinganisa imagnethi, njl.njl.), zilungele iimeko zokusetyenziswa kwe-electromagnetic sensitive.
4. Ubomi benkonzo ende, iindleko zokugcina eziphantsi
Ubunzima begranite buphezulu (ubunzima beMohs 6-7), ukumelana nokuguguleka, ukusetyenziswa ixesha elide akulula ukuguguleka okanye ukuguguleka, ubomi benkonzo bunokufikelela kwiminyaka engaphezu kwama-20. Xa kuthelekiswa nezinto zesinyithi, ayifuni unyango oluqhelekileyo lokulwa nomhlwa okanye ukuthambisa, kwaye iindleko zokulungisa ziphantsi kakhulu.
5.Ukuphakama okuphezulu kunye nokugqitywa komphezulu
Ngokusebenzisa ukugaywa nokupholisha ngokuchanekileyo, ukuba tyaba kwesiseko segranite kunokufikelela kwi-0.005mm/m², kunye nokuba rhabaxa komphezulu we-Ra≤0.2μm, okuqinisekisa ukulingana ngokugqibeleleyo nezixhobo ezichanekileyo (ezifana neqonga le-optical, i-laser interferometer) kunye nokunciphisa iimpazamo zokuhlanganisa.
Okwesibini, iingxaki zesiseko segranite
1. Ubunzima obukhulu, kunzima ukuthwala nokufaka
I-granite inobunzima obukhulu kwaye inzima kune-aluminium okanye intsimbi ngobukhulu obufanayo, nto leyo eyenza ukuba ukuphathwa nokufakelwa kwamaqonga amakhulu kufune izixhobo ezikhethekileyo (ezifana neefolokhwe okanye izixhobo zokuphakamisa), nto leyo enyusa iindleko zokusasazwa.
2. Ubuthuntu obuphezulu, ukumelana nempembelelo ebuthathaka
Nangona igranite inobunzima obuphezulu, yinto ebuthathaka kwaye inokuqhekeka okanye iwe xa ichaphazeleka ngamandla (njengokuwa okanye ukungqubana). Ke ngoko, kufuneka kuthathwe unonophelo olongezelelweyo ngexesha lokuthuthwa nokufakwa ukuze kuthintelwe ukungcangcazela okanye ukungqubana okukhulu.
3. Ukucutshungulwa kunzima kwaye iindleko zokwenza ngokwezifiso ziphezulu
Ukulungiswa kwegranite kufuna izixhobo zoomatshini ezikhethekileyo (ezifana nomatshini wokukrola amatye e-CNC) kunye nezixhobo zedayimani, kwaye isantya sokulungiswa sicotha, nto leyo ebangela iindleko eziphezulu zokwenza ngokwezifiso izakhiwo ezintsonkothileyo (ezifana nemingxunya enemisonto, imiqolo ekhethekileyo) kunye nomjikelo omde wokuhambisa.
4. Utshintsho olukhawulezileyo kubushushu lunokubangela ukuqhekeka okuncinci
Nangona igranite inokuzinza kakuhle kubushushu, ukuba idibana notshintsho olukhulu kubushushu (njengokuhamba ngokukhawuleza ukusuka kwindawo enobushushu obuphantsi ukuya kwindawo enobushushu obuphezulu), iintanda ezincinci zoxinzelelo zinokwenzeka ngaphakathi, kwaye ukuqokelelana kwexesha elide kunokuchaphazela amandla esakhiwo. Ke ngoko, kufuneka isetyenziswe ngononophelo kwiindawo ezinomahluko omkhulu kubushushu.
5. Akukho welding okanye ukucutshungulwa kwesibini
Isiseko sesinyithi singatshintshwa ngokuwelda okanye ngomatshini, kodwa xa igranite yenziwe, phantse akunakwenzeka ukwenza uhlengahlengiso lwesakhiwo (njengokubhoboza, ukusika), ngoko ke inqanaba loyilo kufuneka licwangciswe ngokuchanekileyo ukuze kuthintelwe uhlengahlengiso lwamva.
