Ekufuneni okungapheli kokwenza kahle kakhulu ekukhiqizeni, ukuzinza kwesisekelo somshini we-CNC kubaluleke kakhulu. Njengoba ijubane le-spindle likhuphuka lidlula ama-RPM angu-30,000 futhi ukubekezelelana kuncipha liye ezingeni le-sub-micron, izinto zokwakha zombhede womshini—ngokuvamile ezibizwa ngokuthi “isisekelo”—ziba yisici esinqumayo phakathi kokuphela kobuso obusezingeni eliphezulu kanye nengxenye elahliwe. Sekungamashumi eminyaka, imboni ibilokhu iphikisana ngokufaneleka kwezinto zokwakha ezahlukahlukene, kanti insimbi yendabuko evame ukulahlekelwa yizindlela ezimbili ezinhle kakhulu: i-Natural Granite kanye ne-Mineral Casting (eyaziwa nangokuthi ikhonkrithi ye-polymer noma i-granite yokwenziwa).
Nakuba zombili izinto zinikeza izinzuzo ezibalulekile kunensimbi, ukukhetha phakathi kwazo kudinga ukuqonda okujulile ngezakhiwo zazo zomzimba, ikakhulukazi mayelana nokudambisa ukudlidliza. Lesi sihloko sinikeza ukuhlaziywa kobuchwepheshe kokuthi i-Mineral Casting ne-Natural Granite zihluke kanjani emandleni azo okumunca amandla, ukumelana nokuguquguquka kokushisa, kanye nokugcina ukuzinza kwejometri ezindaweni zomshini ezisheshayo.
I-Fiziksi Yokudlidliza: Kungani Ukudambisa Kubalulekile
Ukuze siqonde ukuqhathanisa, kumele siqale sichaze inkinga. Emishinini ye-CNC, ukudlidliza kuyisitha sokunemba. Ukudlidliza kudalwa ukunyakaza okusheshayo kwama-axes, ukujikeleza kwe-spindle, kanye namandla okusika asebenzisana ne-workpiece. Uma lokhu kudlidliza kungasuswa, kuphumela "ekuxokozeleni" - ukujiya okubonakalayo ebusweni be-workpiece, ukuguguleka kwamathuluzi okusheshayo, kanye nomonakalo ongaba khona eziqondisweni eziqondile zomshini kanye nama-bearings.
Amandla ento yokumunca la mandla e-kinetic bese ewaguqula abe amazinga okushisa aphansi alinganiswa yi-damping coefficient yayo (noma i-loss factor). Yilapho i-Mineral Casting kanye ne-Natural Granite zihluka khona kakhulu ezinsimbini nakwezinye.
I-Granite Yemvelo: Izinga Lomhlaba
I-granite yemvelo ibilokhu iyindinganiso yegolide ye-metrology enembile kakhulu kanye nezisekelo zomshini, ikakhulukazi ku-Coordinate Measuring Machines (CMMs) kanye nokugaya okunembile kakhulu. Ukuthandwa kwayo kuvela emlandweni wayo we-geological. Yakhiwe eminyakeni eyizigidi ngaphansi kokushisa okukhulu kanye nengcindezi, i-granite iyinto ezinzile ngokwemvelo engenakho ukucindezeleka kwangaphakathi.
Amandla okudambisa e-granite yemvelo ayingqayizivele. Inesakhiwo esiqinile, esikristalu esihlinzeka ngokuqina okuphezulu kanye namandla okudambisa cishe izikhathi ezi-5 kuya kweziyi-10 kune-grey cast iron. Lapho igagasi lokudlidliza lifika esisekelweni se-granite, isakhiwo se-crystal esihlanganisiwe esiyinkimbinkimbi sisiza ukuqeda amandla ngokushesha.
Ngaphezu kwalokho, i-granite ayisebenzi ngamakhemikhali futhi ayisebenzi nge-magnetic. Ayigqwali, futhi imelana nemiphumela yokugqwala yama-coolants namafutha. I-coefficient yayo yokwandisa ukushisa cishe iyingxenye yensimbi, okusho ukuthi ayithinteki kakhulu ezinguqukweni zobukhulu ezibangelwa ukushintshashintsha kwezinga lokushisa. Kodwa-ke, ngoba iyinto yemvelo, i-anisotropic—izakhiwo zayo zingahluka kancane kuye ngokuthi okusanhlamvu kuqondiswe kanjani—yize “i-granite emnyama” esezingeni eliphezulu (ngokuvamile i-diabase noma i-basalt) ikhethwa ngqo ngenxa yokufana kwayo.
Ukuphonswa Kwamaminerali: Inhlanganisela Enjiniyela
Ukubumba Okumbiwayo, okuvame ukubizwa ngokuthi ukhonkolo we-polymer noma i-granite yokwenziwa, kumelela isiqongo sezinto zokwakha ezakhiwe ngobunjiniyela. Kuyinhlanganisela ehlanganisiwe equkethe cishe ama-aggregate emvelo angu-90-95% (njenge-quartz, ama-granite chippings, noma i-basalt) ahlanganiswe ndawonye yi-5-10% ye-polymer resin matrix, ngokuvamile i-epoxy.
Lokhu kwakhiwe ngqo ukubhekana nokulinganiselwa kwezinsimbi, futhi kwezinye izici, itshe lemvelo. Inqubo yokukhiqiza ihilela ukuthulula ingxube esikhumbeni esisezingeni lokushisa legumbi, okuvumela ukudalwa kwezakhiwo eziyinkimbinkimbi, ezingenalutho ezinezici ezihlanganisiwe njengeziteshi zokupholisa kanye nemigudu yekhebula.
Ukusebenza kokufiphaza kwe-Mineral Casting kuyisici sayo esichazayo. Ngenxa yemvelo ye-viscoelastic ye-epoxy resin binder, i-Mineral Casting ibonisa amandla okufiphaza ngokuvamile aphindwe ka-6 kuya ku-10 kune-cast iron futhi, okubaluleke kakhulu, ngokuvamile aphindwe ka-2 kuya ku-4 kune-natural granite. I-polymer matrix isebenza njengesithambisi sokushaqeka ezingeni elincane kakhulu, idla ngempumelelo amandla okudlidliza ngaphambi kokuba asakazeke ngesakhiwo somshini.
Umbukiso Wokudambisa: Ukuphonswa Kwamaminerali vs. I-Natural Granite
Uma uqhathanisa lokhu okubili ngqo, umehluko usekusebenzeni kokushabalaliswa kwamandla.
I-Natural Granite ithembele ekungqubuzaneni kwayo kwangaphakathi phakathi kwamakristalu amaminerali. Nakuba isebenza kahle kakhulu, iyinto eqinile. Ezisetshenzisweni zesivinini esikhulu lapho amaza e-harmonic angakha khona ngokushesha, i-granite inikeza ipulatifomu ezinzile kakhulu, kodwa isengadlulisela ukudlidliza kwamaza aphezulu kuye ngokwakheka kwetshe elithile.
I-Mineral Casting, ngokuphambene nalokho, isebenzisa i-composite interface phakathi kwe-hard aggregate ne-soft resin. Lesi sakhiwo sakha i-hysteresis loop enkulu ngesikhathi sokulayisha nokukhipha imithwalo, okuhunyushwa ekumuncweni kwamandla okuphezulu. Izifundo kanye nedatha yemboni ziphakamisa ukuthi isilinganiso somswakama se-Mineral Casting singasukela ku-0.02 kuya ku-0.045, siphumelele kakhulu ekugcineni okuphansi kwe-granite's spectrum. Lokhu kwenza i-Mineral Casting isebenze kahle kakhulu emisebenzini "evame ukuxokozela" njengokubhoboza imigodi ejulile, ukugaya ngesivinini esikhulu kwe-titanium, noma ukuqeda ama-pass lapho ukugoba kobuso kubaluleke kakhulu.
Ngokwendlela engokoqobo, umshini onesisekelo se-Mineral Casting ungase uhlale ngokushesha ngemva kokuhamba okusheshayo kunomshini onesisekelo se-granite, okuvumela izikhathi zomjikelezo ezimfushane kanye nomthamo ophezulu.
Ukuzinza Kokushisa Nobuqotho Bejiyometri
Ngale kokudlidliza, ukuziphatha kokushisa kuyisici esibalulekile sokuhlukanisa.
I-Natural Granite yaziwa ngokungashisi kwayo okushisa. Ine-conductivity ephansi yokushisa, okusho ukuthi kuthatha isikhathi eside ukufudumala noma ukupholisa. Lokhu "kubambezeleka" kuyazuzisa ezindaweni ezinamazinga okushisa ashintshashintshayo, njengoba isisekelo somshini sisebenza njengesinki sokushisa, sigcina i-geometry yaso noma ngabe izinga lokushisa phansi kwesitolo lishintsha. Kodwa-ke, i-granite kunzima ukuyishicilela. Ukudala indawo eyisicaba ngokuphelele kudinga umsebenzi onekhono nesikhathi, futhi izici zokushumeka (njengezinto zokufaka ezinezintambo) zivame ukudinga ukubhoboza nokunamathisela, okungaletha amaphuzu abuthakathaka.
I-Mineral Casting inikeza uhlobo oluhlukile lokuzinza kokushisa. Ngenxa yokuthi iyelapheka ekushiseni kwegumbi, ayinaso ingcindezi yokushisa esele. Ngokungafani nensimbi ephonswe, engagobeka njengoba ukucindezeleka kwangaphakathi kunciphisa eminyakeni yokusetshenziswa, i-Mineral Casting igcina isimo sayo sejometri ngokungenamkhawulo. I-coefficient yayo yokwanda kokushisa iphansi kakhulu futhi ingalungiswa ngesikhathi senqubo yokwenza ukuze ifane neyensimbi, okuyinto enenzuzo lapho ufaka iziqondiso eziqondile zensimbi ngqo esisekelweni.
Kodwa-ke, i-Mineral Casting ine-thermal conductivity ephansi kune-granite. Nakuba lokhu kunikeza ukuzinza, kusho ukuthi uma kukhishwa ukushisangaphakathiisisekelo (isb., esivela kunjini efakwe ngqo kuso), lokho kushisa kungase kunganyamalali ngokushesha njengoba bekuyonyamalala ku-granite. Ngakho-ke, amasu okuphatha ukushisa, njengeziteshi zokupholisa zangaphakathi (eziphonswa kalula ku-Mineral Casting), zivame ukudingeka kakhulu ezisekelweni zekhonkrithi ze-polymer.
Inkululeko Yokuklama kanye Nemiphumela Yokukhiqiza
Ukukhetha phakathi kwalezi zinto nakho kuthinta ukwakheka komshini.
I-Natural Granite inqunyelwe ubukhulu bamabhulokhi aqoshwe phansi. Izisekelo ezinkulu zomshini zivame ukudinga ukuhlanganiswa kwezingcezu eziningi zamatshe, okufaka amalunga angathinta ukuqina nokumanzisa. Ngaphezu kwalokho, i-granite iyaphuka; umthelela obukhali ovela kuthuluzi eliwayo noma umsebenzi ungaqhekeza isisekelo, okuholela ekulungisweni okubizayo noma ekushintshweni.
I-Mineral Casting inikeza inkululeko yokuklama engenakuqhathaniswa. Ingafakwa ezimweni eziyinkimbinkimbi, ezi-monolithic ezinobukhulu obuhlukahlukene bodonga. Lokhu kuvumela onjiniyela ukuthi bathuthukise isilinganiso sokuqina-kuya-kwesisindo, badale izakhiwo ezilula kodwa eziqinile kunezakwabo ze-granite. Ngaphezu kwalokho, izakhi ezisebenzayo—njengezintambo zokufaka, imigqa yomoya, kanye nezindawo zokubeka izikali eziqondile—zingafakwa ngqo ezintweni, kuncishiswe isikhathi sokuhlangana futhi kuqedwe imithombo engaba khona yokudlidliza okubangelwa amalunga aboshwe.
Isiphetho: Ukukhetha Isisekelo Esifanele
Kokubili i-Natural Granite kanye ne-Mineral Casting kumelela igxathu elikhulu eliya phambili kusukela ku-cast iron yendabuko, okunikeza ukuzinza okudingekayo ekukhiqizweni kokunemba kwesimanje.
Uma isicelo sakho sihilela i-metrology enembile kakhulu noma izindawo lapho ukulibaziseka kokushisa kuyindaba eyinhloko, i-Natural Granite isalokhu iyisinqumo esimangalisayo ngenxa yokuhlala kwayo njalo kanye nerekhodi eliqinisekisiwe kuma-CMM.
