Okokuqala, izinzuzo zesisekelo se-granite
1. Ukuqina okuphezulu nokuqina
I-Granite inobukhulu obuphezulu (2.6-3.1g /cm³), kanti i-modulus kaYoung (i-modulus elastic) ingafinyelela ku-50-100 GPa, ephakeme kakhulu kunensimbi evamile (cishe i-200 GPa), kodwa ngenxa yesakhiwo sayo sekristalu esi-isotropic, cishe ayinayo i-deformation yepulasitiki ekusetshenzisweni kwesikhathi eside. Uma kuqhathaniswa nezinto zensimbi, i-coefficient yokwandisa ukushisa kwe-granite iphansi kakhulu (cishe i-5×10⁻⁶/℃), endaweni yokushintshashintsha kwezinga lokushisa isengagcina ukuzinza okuhle kakhulu kobukhulu, gwema ngenxa yokwanda kokushisa ukufinyela okubandayo okuthinta ukunemba kwemishini.
2. Ukusebenza okuhle kakhulu kokunciphisa ukudlidliza
Isakhiwo sangaphakathi sekristalu segranite sinokudambisa okuphezulu kwangaphakathi, okungamunca ngempumelelo ukudlidliza okunemvamisa ephezulu futhi kunciphise ukwenzeka kwe-resonance. Uma kuqhathaniswa nesisekelo sensimbi, igranite inamandla okunciphisa ukudlidliza aqinile aphakathi kuka-20Hz-1kHz, okunikeza indawo yokuqala "ehlanzekile" yesistimu yokuhlukanisa ukudlidliza okusebenzayo kanye nokunciphisa umthwalo wokulawula okusebenzayo okulandelayo.
3. Ukumelana nokugqwala, okungeyona i-magnetic, okubanzi okusebenzayo
Ukuqina kwamakhemikhali e-granite, ukumelana nokugqwala kwe-asidi ne-alkali, ngeke kugqwale noma ku-oxidation, kufanelekela igumbi elihlanzekile, umswakama ophezulu noma indawo egqwalisayo. Ngaphezu kwalokho, i-granite iyinto engeyona i-magnetic, ngeke iphazamise amathuluzi okunemba (njenge-electron microscopy, imishini yokulinganisa i-magnetic, njll.), efanelekile ezimweni zokusetshenziswa ezibucayi ze-electromagnetic.
4. Impilo yesevisi ende, izindleko eziphansi zokulungisa
Ubulukhuni be-granite buphezulu (ubulukhuni be-Mohs 6-7), ukumelana nokuguguleka, ukusetshenziswa kwesikhathi eside akulula ukuguguleka noma ukuguguleka, impilo yesevisi ingafinyelela eminyakeni engaphezu kwengu-20. Uma kuqhathaniswa nezinto zensimbi, ayidingi ukwelashwa okuvamile kokulwa nokugqwala noma ukugcotshwa, futhi izindleko zokulungisa ziphansi kakhulu.
5. Ukuthamba okuphezulu kanye nokuqeda kobuso
Ngokusebenzisa ukugaya nokupholisha ngokunembile, ukuba yisicaba kwesisekelo segranite kungafinyelela ku-0.005mm/m², kanye nokuba lukhuni kobuso okungu-Ra≤0.2μm, okuqinisekisa ukulingana okuphelele nemishini enembile (njengeplatifomu yokukhanya, i-laser interferometer) kanye nokunciphisa amaphutha okuhlanganisa.
Okwesibili, ukushiyeka kwesisekelo se-granite
1. Isisindo esikhulu, kunzima ukusithwala nokusifaka
I-granite inobukhulu obukhulu futhi inzima kune-aluminium noma insimbi ngobukhulu obufanayo, okwenza ukuphathwa nokufakwa kwamapulatifomu amakhulu kudinge imishini ekhethekile (njenge-forklift noma amathuluzi okuphakamisa), okwandisa izindleko zokuthunyelwa.
2. Ukucasuka okuphezulu, ukumelana nobuthakathaka bomthelela
Nakuba i-granite inobulukhuni obukhulu, iyinto ephuka kalula futhi ingaqhekeka noma iwe uma ishaywa ngamandla (njengokuwa noma ukushayisana). Ngakho-ke, kufanele kuqashelwe kakhulu ngesikhathi sokuthutha nokufakwa ukuze kugwenywe ukudlidliza okukhulu noma ukushayisana.
3. Ukucubungula kunzima futhi izindleko zokwenza ngokwezifiso ziphezulu
Ukucutshungulwa kwe-granite kudinga amathuluzi omshini akhethekile (njengomshini wokuqopha amatshe we-CNC) namathuluzi edayimane, futhi isivinini sokucubungula sihamba kancane, okuholela ezindleleni eziphakeme zokwenza ngezifiso izakhiwo eziyinkimbinkimbi (njengemigodi enezintambo, imifantu enesimo esikhethekile) kanye nomjikelezo omude wokulethwa.
4. Ukushintsha kwezinga lokushisa okungazelelwe kungabangela imifantu emincane
Nakuba i-granite inokuzinza okuhle kokushisa, uma ihlangabezana nezinguquko ezinkulu zokushisa (njengokuhamba ngokushesha kusuka endaweni yokushisa ephansi kuya endaweni yokushisa ephezulu), kungase kube nemifantu emincane yokucindezeleka ngaphakathi, futhi ukuqongelela isikhathi eside kungathinta amandla esakhiwo. Ngakho-ke, kufanele isetshenziswe ngokuqapha ezindaweni ezinomehluko omkhulu wokushisa.
5. Akukho ukushisela noma ukucubungula kwesibili
Isisekelo sensimbi singashintshwa ngokushisela noma ngomshini, kodwa uma i-granite isivele yakhekile, cishe akunakwenzeka ukwenza izinguquko zesakhiwo (njengokubhoboza, ukusika), ngakho-ke isigaba sokuklama kumele sihlelwe kahle ukuze kugwenywe izinguquko zakamuva.
