Pofuna kufunafuna luso lopanga zinthu, kukhazikika kwa maziko a makina a CNC ndikofunikira kwambiri. Pamene liwiro la spindle likupitirira 30,000 RPM ndipo kulekerera kukuchepa kufika pamlingo wa sub-micron, kapangidwe ka makinawo—kamene nthawi zambiri kamatchedwa “maziko”—kamakhala chinthu chofunikira kwambiri pakati pa kumalizidwa kwapamwamba kwambiri ndi gawo lotayidwa. Kwa zaka zambiri, makampaniwa akhala akukambirana za ubwino wa zipangizo zosiyanasiyana za maziko, ndipo chitsulo chachikhalidwe nthawi zambiri chimataya malo ake ndi njira ziwiri zabwino kwambiri: Natural Granite ndi Mineral Casting (yomwe imadziwikanso kuti polymer concrete kapena granite yopangira).
Ngakhale kuti zipangizo zonsezi zimakhala ndi ubwino waukulu kuposa chitsulo, kusankha pakati pawo kumafuna kumvetsetsa bwino za makhalidwe awo enieni, makamaka pankhani ya kugwedezeka kwa kugwedezeka. Nkhaniyi ikupereka kusanthula kwaukadaulo kwa momwe Mineral Casting ndi Natural Granite zimasiyanirana pa kuthekera kwawo kuyamwa mphamvu, kukana kusintha kwa kutentha, komanso kusunga kukhazikika kwa geometric m'malo opangira makina othamanga kwambiri.
Fiziki ya Kugwedezeka: Chifukwa Chake Kudambitsa Madzi Ndikofunikira
Kuti timvetse kufananiza, choyamba tiyenera kufotokoza vuto. Mu makina a CNC, kugwedezeka ndi mdani wa kulondola. Kugwedezeka kumachitika chifukwa cha kuyenda mwachangu kwa nkhwangwa, kuzungulira kwa spindle, ndi mphamvu zodula zomwe zimagwirizana ndi workpiece. Ngati kugwedezeka kumeneku sikutha, kumabweretsa "kugwedezeka" - kugwedezeka kooneka pamwamba pa workpiece, kuwonongeka kwa chida mwachangu, komanso kuwonongeka komwe kungachitike pa malangizo ndi ma bearing a makinawo.
Kuthekera kwa chinthu kuyamwa mphamvu ya kinetic iyi ndikuisintha kukhala kutentha kochepa kumayesedwa ndi damping coefficient yake (kapena loss factor). Apa ndi pomwe Mineral Casting ndi Natural Granite zimasiyana kwambiri ndi zitsulo komanso kuchokera kwa wina ndi mnzake.
Granite Yachilengedwe: Muyezo wa Geological
Granite wachilengedwe wakhala muyeso wagolide wa metrology yolondola kwambiri komanso maziko a makina, makamaka mu Makina Oyezera Ogwirizana (CMMs) ndi kugaya kolondola kwambiri. Kutchuka kwake kumachokera ku mbiri yake ya geology. Yopangidwa kwa zaka mamiliyoni ambiri pansi pa kutentha kwakukulu ndi kupanikizika, granite ndi chinthu chokhazikika mwachilengedwe chomwe sichimavutitsa mkati.
Mphamvu yonyowetsa madzi ya granite yachilengedwe ndi yapadera kwambiri. Ili ndi kapangidwe kolimba, ka kristalo komwe kamapereka kulimba kwakukulu komanso mphamvu yonyowetsa madzi pafupifupi nthawi 5 mpaka 10 kuposa ya chitsulo chotuwa. Pamene mafunde ogwedezeka agunda maziko a granite, kapangidwe ka kristalo kolumikizana bwino kumathandiza kutaya mphamvu mwachangu.
Kuphatikiza apo, granite ndi yopanda mphamvu ya mankhwala ndipo siigwiritsa ntchito maginito. Siichita dzimbiri, ndipo imalimbana ndi kuwonongeka kwa zinthu zoziziritsira ndi mafuta. Kuchuluka kwa kutentha kwake kuli pafupifupi theka la chitsulo, zomwe zikutanthauza kuti siikhudzidwa kwambiri ndi kusintha kwa kukula komwe kumachitika chifukwa cha kusinthasintha kwa kutentha kwa malo. Komabe, chifukwa ndi chinthu chachilengedwe, ndi anisotropic—makhalidwe ake amatha kusiyana pang'ono kutengera komwe kuli tirigu—ngakhale kuti “granite wakuda” wapamwamba kwambiri (nthawi zambiri diabase kapena basalt) amasankhidwa makamaka chifukwa cha kufanana kwake.
Kuponya Mineral: Chopangidwa ndi Mainjiniya
Kuponya Mineral, komwe nthawi zambiri kumatchedwa konkireti ya polymer kapena granite yopangira, kumayimira pamwamba pa zipangizo zopangidwa ndi akatswiri. Ndi chisakanizo chophatikizana chomwe chimakhala ndi pafupifupi 90-95% ya zinthu zachilengedwe (monga quartz, granite chipings, kapena basalt) zomangiriridwa pamodzi ndi 5-10% ya polymer resin matrix, nthawi zambiri epoxy.
Zinthu zimenezi zinapangidwa makamaka kuti zithetse mavuto a zitsulo, komanso, m'mbali zina, miyala yachilengedwe. Njira yopangira zinthuzi imaphatikizapo kutsanulira chisakanizocho mu nkhungu kutentha kwa chipinda, zomwe zimathandiza kupanga nyumba zovuta, zopanda kanthu zokhala ndi zinthu zophatikizika monga njira zoziziritsira ndi ma waya.
Kagwiridwe kake ka Mineral Casting kochepetsa chinyezi ndiye kamene kamapangitsa kuti chikhale cholimba. Chifukwa cha mtundu wa epoxy resin binder, Mineral Casting imakhala ndi mphamvu yochepetsera chinyezi yomwe nthawi zambiri imakhala yayikulu nthawi 6 mpaka 10 kuposa chitsulo chosungunuka ndipo, chofunika kwambiri, nthawi zambiri imakhala yayikulu nthawi 2 mpaka 4 kuposa granite yachilengedwe. Matrix a polymer amagwira ntchito ngati choyamwa kugunda kwamphamvu pamlingo wa microscopic, zomwe zimapangitsa kuti "zidye" mphamvu yogwedezeka isanafalikire kudzera mu kapangidwe ka makina.
Kulimbana ndi Madzi: Kuponya Mineral vs. Natural Granite
Poyerekeza ziwirizi mwachindunji, kusiyana kuli mu njira yofalitsira mphamvu.
Granite Yachilengedwe imadalira kukangana kwake kwamkati pakati pa makhiristo a mchere. Ngakhale kuti ndi yothandiza kwambiri, ndi chinthu cholimba. Mu ntchito zothamanga kwambiri komwe ma frequency a harmonic amatha kusonkhana mwachangu, granite imapereka nsanja yokhazikika kwambiri, koma ikhozabe kutumiza kugwedezeka kwa ma frequency apamwamba kutengera kapangidwe kake ka miyala.
Mosiyana ndi zimenezi, Mineral Casting imagwiritsa ntchito njira yolumikizirana pakati pa chogwirira cholimba ndi utomoni wofewa. Kapangidwe kameneka kamapanga kuzungulira kwakukulu kwa hysteresis panthawi yokweza ndi kutsitsa, zomwe zikutanthauza kuti mphamvu imayamwa bwino kwambiri. Kafukufuku ndi deta yamakampani akuwonetsa kuti chiŵerengero cha damping cha Mineral Casting chingachokere pa 0.02 mpaka 0.045, zomwe zimapangitsa kuti chikhale chocheperako kuposa malekezero otsika a granite. Izi zimapangitsa Mineral Casting kukhala yothandiza kwambiri pa ntchito "zosavuta kulankhula" monga kuboola mabowo akuya, kupukuta titaniyamu mwachangu, kapena kumaliza kumene kuuma kwa pamwamba ndikofunikira.
Mwachidule, makina okhala ndi maziko a Mineral Casting amatha kukhazikika mwachangu akayenda mofulumira kuposa makina okhala ndi maziko a granite, zomwe zimapangitsa kuti nthawi yozungulira ikhale yochepa komanso kuti mphamvu yogwira ntchito ikhale yokwera.
Kukhazikika kwa Kutentha ndi Kukhulupirika kwa Jiometri
Kupatula kugwedezeka, khalidwe la kutentha ndi chinthu chofunikira kwambiri.
Granite Yachilengedwe imadziwika ndi kutentha kwake kosasinthasintha. Ili ndi mphamvu yochepa yotenthetsera, zomwe zikutanthauza kuti imatenga nthawi yayitali kutentha kapena kuzizira. "Kuchedwa" kumeneku ndi kothandiza m'malo omwe kutentha kumasinthasintha, chifukwa maziko a makina amagwira ntchito ngati chotenthetsera, kusunga mawonekedwe ake ngakhale kutentha kwa pansi pa shopu kukusintha. Komabe, granite ndi yovuta kuigwiritsa ntchito. Kupanga malo osalala bwino kumafuna ntchito yaukadaulo komanso nthawi, ndipo zinthu zoyikamo (monga zoyikamo ulusi) nthawi zambiri zimafuna kuboola ndi kumata, zomwe zingayambitse malo ofooka.
Kupaka Mineral kumapereka mtundu wina wa kukhazikika kwa kutentha. Popeza kumachiritsidwa kutentha kwa chipinda, sikumatsalira kutentha. Mosiyana ndi chitsulo chopangidwa ndi chitsulo, chomwe chimatha kupindika pamene kupsinjika kwamkati kumachepa pakapita zaka zambiri chikugwiritsidwa ntchito, Kupaka Mineral kumakhala ndi mawonekedwe ake a geometrical kwamuyaya. Kuchuluka kwa kutentha kwake kumakhala kochepa kwambiri ndipo kumatha kusinthidwa panthawi yopanga kuti kufanane ndi chitsulo, zomwe zimakhala zabwino poyika zitsogozo zachitsulo molunjika pansi.
Komabe, Mineral Casting ili ndi kutentha kochepa kuposa granite. Ngakhale izi zimapangitsa kuti kutentha kukhale kokhazikika, zikutanthauza kuti ngati kutentha kwapangidwamkatimaziko (monga, kuchokera ku mota yomwe yayikidwa molunjika), kutenthako sikungatha msanga monga momwe kungathere mu granite. Chifukwa chake, njira zoyendetsera kutentha, monga njira zoziziritsira mkati (zomwe zimaponyedwa mosavuta mu Mineral Casting), nthawi zambiri zimakhala zofunika kwambiri pa maziko a konkriti wa polima.
Ufulu wa Kupanga ndi Zotsatira Zake
Kusankha pakati pa zipangizozi kumakhudzanso kapangidwe ka makina.
Granite Yachilengedwe imachepetsedwa ndi kukula kwa mabuloko ogwetsedwa. Maziko akuluakulu a makina nthawi zambiri amafunika kulumikiza zidutswa zingapo za miyala, zomwe zimayambitsa zolumikizira zomwe zingakhudze kuuma ndi kunyowa. Kuphatikiza apo, granite imakhala yofooka; kugwedezeka kwakukulu kuchokera ku chida chogwa kapena chogwirira ntchito kumatha kuswa maziko, zomwe zimapangitsa kuti pakhale kukonza kokwera mtengo kapena kusintha.
Kuyika Mineral Casting kumapereka ufulu wosayerekezeka wopanga. Kungathe kupangidwa m'mawonekedwe ovuta, a monolithic okhala ndi makulidwe osiyanasiyana a makoma. Izi zimathandiza mainjiniya kukonza chiŵerengero cha kuuma ndi kulemera, ndikupanga nyumba zopepuka koma zolimba kuposa granite. Kuphatikiza apo, zinthu zogwirira ntchito—monga ulusi womangirira, mizere yopumira, komanso zomangira za mzere—zikhoza kuponyedwa mwachindunji mu chinthucho, kuchepetsa nthawi yomangira ndikuchotsa magwero omwe angayambitse kugwedezeka chifukwa cha ma bolts.
Mapeto: Kusankha Maziko Oyenera
Granite Yachilengedwe ndi Mineral Casting zonse ziwiri zikuyimira patsogolo kwambiri kuchokera ku chitsulo chachikhalidwe, zomwe zimapangitsa kuti zikhale zokhazikika pakupanga zinthu zamakono molondola.
Ngati ntchito yanu ikuphatikizapo kuyeza kwapamwamba kwambiri kapena malo omwe kuchedwa kwa kutentha ndiko nkhawa yayikulu, Natural Granite ikadali chisankho chabwino chifukwa cha kukhazikika kwake m'ma geology komanso mbiri yake yotsimikizika mu CMMs.
