Emishinini yokulawula izinombolo ye-CNC, yize i-granite isibe yinto ebalulekile ngenxa yezakhiwo zayo ezihlukile, izinkinga zayo ezingokwemvelo zingase zibe nomthelela othile ekusebenzeni kwemishini, ukusebenza kahle kokucubungula kanye nezindleko zokulungisa. Okulandelayo ukuhlaziywa kwemiphumela ethile ebangelwa ukushiyeka kwe-granite kusuka ezilinganisweni eziningi:
Okokuqala, izinto zibuthakathaka kakhulu futhi zisengozini yokuphuka nokulimala
Inkinga eyinhloko: I-Granite iyitshe lemvelo futhi empeleni iyinto ebuthakathaka futhi iqinile kancane (inani lokuqina komthelela licishe libe ngu-1-3J/cm², elingaphansi kakhulu kune-20-100J/cm² yezinto zensimbi).
Umthelela emishinini ye-CNC:
Izingozi zokufakwa kanye nezokuthutha: Ngesikhathi sokuhlanganiswa noma ukuphathwa kwemishini, uma ingqubuzana noma iwe, izingxenye zegranite (ezifana nezisekelo kanye nemigqa yokuqondisa) zivame ukuqhekeka noma ukuqhekeka kwamakhona, okuholela ekwehlulekeni kokunemba. Isibonelo, uma ipulatifomu yegranite yomshini wokulinganisa onezixhumanisi ezintathu iba nemifantu efihliwe ngenxa yokusebenza okungafanele ngesikhathi sokufakwa, kungaholela ekuwohlokeni kancane kancane kokusicaba ngenxa yokusetshenziswa isikhathi eside, okuthinta imiphumela yokulinganisa.
Izingozi ezifihliwe enkambisweni yokucubungula: Lapho imishini ye-CNC ihlangabezana nokugcwala ngokweqile okungazelelwe (njengokungqubuzana kwethuluzi nomsebenzi), izinsimbi zokuqondisa ze-granite noma amatafula okusebenzela angase aphuke ngenxa yokungakwazi ukumelana namandla okushaya ngokushesha, okubangela ukuba imishini ivalwe ukuze ilungiswe, futhi kubangele ngisho nochungechunge lokwehluleka kokunemba.
Okwesibili, ubunzima obukhulu bokucubungula buvimbela ukwakheka kwezakhiwo eziyinkimbinkimbi
Izithiyo Eziyinhloko: I-Granite inobulukhuni obuphezulu (6-7 esikalini se-Mohs), futhi idinga ukugaywa nokucutshungulwa ngamathuluzi akhethekile njengamasondo okugaya idayimane, okuholela ekusebenzeni kahle kokucubungula okuphansi (ukusebenza kahle kokugaya kungu-1/5 kuya ku-1/3 kuphela kwezinto zensimbi), futhi izindleko zokucubungula izindawo ezigobile eziyinkimbinkimbi ziphezulu.
Umthelela emishinini ye-CNC:
Imikhawulo yokwakheka kwesakhiwo: Ukuze kugwenywe ubunzima bokucubungula, izingxenye zegranite zivame ukuklanywa ngezimo ezilula zejometri (njengezingqwembe, imigqa yokuqondisa engunxande), okwenza kube nzima ukufeza imigodi yangaphakathi eyinkimbinkimbi, amapuleti aqinile alula kanye nezinye izakhiwo ezingafezwa ngokusika/ukusika ngezinto zensimbi. Lokhu kuholela eqinisweni lokuthi isisindo sesisekelo segranite sivame ukuba sikhulu kakhulu (10%-20% sinzima kunensimbi ephonswe ngevolumu efanayo), okungase kwandise umthwalo wonke wemishini futhi kuthinte ukusebenza kwempendulo enamandla ngesikhathi sokunyakaza kwesivinini esikhulu.
Izindleko eziphezulu zokulungisa nokufaka esikhundleni: Uma kwenzeka ukuguguleka noma umonakalo ezindaweni ezithile ze-granite, kunzima ukuzilungisa ngezindlela ezifana nokushisela noma ukusika. Ngokuvamile, yonke ingxenye idinga ukushintshwa, futhi izingxenye ezintsha kudingeka ziphinde zigaywe futhi zilinganiswe ukuze kutholakale ukunemba, okuholela ekungasebenzi isikhathi eside (ukufaka esikhundleni esisodwa kungathatha amasonto ama-2-3), kanye nokwenyuka okukhulu kwezindleko zokulungisa.
Iii. Ukungaqiniseki Kokwakheka Kwemvelo Nokukhubazeka Kwangaphakathi
Inkinga eyinhloko: Njengeminerali yemvelo, i-granite inemifantu yangaphakathi engalawuleki, ama-pores noma ukungcola kwamaminerali, futhi ukufana kwezinto ezibonakalayo zemithambo ehlukene kuyahlukahluka kakhulu (ukuguquguquka kobuningi kungafinyelela ku-±5%, ukuguquguquka kwe-modulus elastic ±8%).
Umthelela emishinini ye-CNC:
Ingozi yokuzinza ngokunemba: Uma indawo yokucubungula yengxenye igcwele imifantu yangaphakathi, ngesikhathi sokusetshenziswa isikhathi eside, imifantu inganda ngenxa yokucindezeleka, okubangela ukuguquka kwendawo futhi kuthinte ukunemba kwemishini. Isibonelo, uma imisele yokuqondisa ye-granite yomshini wokugaya we-CNC inezimbobo zomoya ezifihliwe, ingawa kancane kancane ngaphansi kokudlidliza okuvama kakhulu, okuholela ephutheni lokuqondile ngokweqile kwemisele yokuqondisa.
Umehluko wokusebenza kweqembu: Izinto ze-granite ezivela kumaqoqo ahlukene zingase zibhekane nokushintshashintsha kwezinkomba ezibalulekile njenge-coefficient of thermal expansion kanye nokusebenza kwe-damping ngenxa yomehluko ekwakhiweni kwamaminerali, okuthinta ukuhambisana kokukhiqizwa kweqembu ngemishini. Emigqeni yokukhiqiza ezenzakalelayo edinga ukusebenzisana kwamadivayisi amaningi, umehluko onjalo ungaholela ekwandeni kokusabalala kokunemba kokucubungula.
Okwesine, inzima, okuthinta ukusebenza okuguquguqukayo kwemishini
Inkinga eyinhloko: I-Granite inobukhulu obuphezulu (2.6-3.0g/cm³), futhi isisindo sayo cishe siphindwe izikhathi ezingu-1.2 kunensimbi ecijile kanye nesisindo esiphindwe izikhathi ezingu-2.5 kunese-aluminium alloy ngaphansi komthamo ofanayo.
Umthelela emishinini ye-CNC:
Ukulibaziseka kokuphendula kokunyakaza: Ezikhungweni zomshini ezinesivinini esikhulu noma emishinini enezingqimba ezinhlanu, isisindo esikhulu sesisekelo segranite sizokwandisa i-inertia yomthwalo wesikulufu se-motor/lead esiqondile, okuholela ekubambezelekeni kokuphendula okuguquguqukayo ngesikhathi sokusheshisa/ukwehla kwesivinini (okungase kwandise isikhathi sokuqala ngo-5% kuya ku-10%), okuthinta ukusebenza kahle kokucubungula.
Ukusetshenziswa kwamandla okwandisiwe: Ukushayela izingxenye ze-granite ezisindayo kudinga ama-servo motor anamandla kakhulu, okuphakamisa ukusetshenziswa kwamandla okuphelele kwemishini (izilinganiso zangempela zibonisa ukuthi ngaphansi kwezimo ezifanayo zokusebenza, ukusetshenziswa kwamandla kwemishini yesisekelo se-granite kuphakeme ngo-8%-12% kunokwemishini yensimbi ephonswe ngensimbi). Ukusetshenziswa kwesikhathi eside kuzokhulisa izindleko zokukhiqiza.
Okwesihlanu, ikhono lokumelana nokushaqeka kokushisa lilinganiselwe
Inkinga eyinhloko: Nakuba i-granite inomthamo ophansi wokwanda kokushisa, ukuhanjiswa kwayo kokushisa akukuhle (ngokushisa okungu-1.5-3.0W/(m · K) kuphela, cishe okungu-1/10 kwensimbi ephonswe ngensimbi), futhi izinguquko zokushisa zendawo ezisheshayo zivame ukudala ukucindezeleka kokushisa.
Umthelela emishinini ye-CNC:
Inkinga yokwehluka kwezinga lokushisa endaweni yokucubungula: Uma uketshezi olusikayo lugugule indawo yendawo yetafula lokusebenza le-granite, lungabangela i-gradient yokushisa (njengokwehluka kwezinga lokushisa elingu-5-10℃) phakathi kwale ndawo nendawo ezungezile, okuholela ekuguqukeni okuncane kokushisa (inani lokuguqulwa lingafinyelela ku-1-3μm), okuthinta ukuhambisana kokunemba kokucubungula ngokunemba (njengokugaya igiya lezinga le-micron).
Ingozi yokukhathala kokushisa kwesikhathi eside: Ezindaweni zokusebenzela lapho kuqaliswa khona izinto ezintsha nokuvalwa noma umehluko omkhulu wokushisa phakathi kwemini nobusuku, izingxenye zegranite zingase zibe nemifantu emincane ngenxa yokwanda nokuncipha kokushisa okuphindaphindiwe, okwenza kancane kancane kube buthaka ukuqina kwesakhiwo.
