Kubunjiniyela bokucacisa, ukunemba komshini akuvamile ukuchazwa yisakhi esisodwa. Kunalokho, kuwumphumela wendlela izinto zokwakha, izakhiwo, kanye nezinhlelo zokunyakaza ezisebenzisana ngayo ngokuhamba kwesikhathi. Njengoba ukubekezelelana kusuka kuma-micron kuya kuma-micron angaphansi, izixazululo zendabuko ziya ngokuya zingatshazwa, ikakhulukazi uma kukhulunywa ngemigwaqo yokuqondisa, izisekelo zomshini, kanye nobuchwepheshe bokuthwala.
Eminyakeni engamashumi amabili edlule, i-granite isuke endaweni esetshenziswa kakhulu kumapuleti angaphezulu iye endaweni eyisisekelo yesakhiwo emishinini ephezulu. Ngesikhathi esifanayo, ama-air bearing avele njengendlela ehlukile ewusizo esikhundleni sama-mechanical bearing avamile. Ukuqonda ukuthi lobu buchwepheshe buqhathaniswa kanjani—nokuthi busebenza kanjani ndawonye—kuye kwaba yinto ebalulekile kubaklami bemishini nabakhiqizi.
I-Granite Guideways kanye ne-Cast Iron Guideways: Ushintsho kwiFilosofi Yokuklama
Iminyaka eminingi, imigwaqo yensimbi ephonswe yayiyisinqumo esizenzakalelayo kumathuluzi omshini. Ukuthandwa kwawo kwavela ekujwayelaneni, ukulula komshini, kanye nokusebenza okwamukelekayo kokukhiqiza okuvamile. Ezindaweni lapho ukushintshashintsha kokushisa nokudlidliza kwakulawuleka khona, insimbi ephonswe yaletha imiphumela ethembekile.
Kodwa-ke, njengoba imishini iqala ukusebenza ngesivinini esiphezulu kanye nesisombululo esiphezulu sokulinganisa, imikhawulo yabonakala kakhulu. Insimbi ecijile isabela ngokushesha ekushintsheni kwezinga lokushisa futhi idlulise ukudlidliza kalula kunalokho abaklami abangathanda. Ezikhathini zokusebenza ezinde, ukuguguleka okuhlobene nokuthambisa kungaletha namaphutha amancane kodwa alinganisekayo.
Izindlela zokuqondisa ze-granite zimelela ifilosofi yokuklama ehlukile. Esikhundleni sokubuyisela ubuthakathaka bezinto ezibonakalayo ngobuningi obengeziwe noma ukudambisa kwangaphandle, i-granite incike ezicini zayo zomzimba zangaphakathi. I-granite enobukhulu obuphezulu ngokwemvelo imunca ukudlidliza futhi isabela kancane ekushintsheni kokushisa. Lokhu kudala inkomba eqinile yokunyakaza okunembile, ikakhulukazi ezinhlelweni zokuhlola kanye ne-metrology lapho amathonya emvelo engenakususwa ngokuphelele.
Ngenxa yalokho, imigwaqo yegranite ikhethwa kakhulu ukuze isetshenziswe lapho ukuphindaphindeka kanye nokuzinza kwesikhathi eside kubaluleke kakhulu kunamandla okusika angavuthiwe.
Indima Ekhulayo Yabakhiqizi Bemishini Ye-Granite
Ukwamukelwa kwemigwaqo ye-granite kuye kwaphakamisa ngokwemvelo ukubaluleka kwabakhiqizi bemishini ye-granite. Namuhla, laba baphakeli abasasebona abahlinzeki bezinto ezibonakalayo abavamile. Basebenza njengabalingani ekwakhiweni kwemishini.
Yesimanjeizisekelo zomshini we-graniteziyizakhiwo ezakhiwe ngendlela ehlelekile. I-geometry yazo, ukusatshalaliswa kwesisindo, kanye nobuso besikhombimsebenzisi kuklanyelwe ukulawula ukuguquguquka, izindlela zokudlidliza, kanye nokulingana kokushisa. Izinto ezifakiwe, izici ezinezintambo, kanye nobuso bereferensi yokuthwala kuhlanganiswe ngesikhathi sokukhiqiza kunokuba kufakwe kamuva njengeziphazamiso.
Leli zinga lokuhlanganiswa libaluleke kakhulu emishinini yokulinganisa ehlelekile, imishini ye-semiconductor, kanye namapulatifomu okuhlola okukhanya. Kulezi zinhlelo, isisekelo somshini akuyona nje into yokusekela—yinkomba eyinhloko echaza ukunemba kuyo yonke imvilophu yokusebenza.
Abakhiqizi abaphambili batshala imali eningi ekugayeni ngokunemba, ezindaweni zokusebenzela ezilawulwa isimo sezulu, kanye nezinhlelo zokuhlola ezilandelekayo. Umgomo awukona nje ukufeza ukunemba kokuqala, kodwa futhi ukuqinisekisa ukuthi ukunemba kuhlala kuzinzile eminyakeni yokusebenza.
Ama-Air Bearings nama-Mechanical Bearings: Izimpendulo Ezihlukene Zombuzo Ofanayo
Ukukhethwa kwamabhereyitha akuhlukaniseki ekukhetheni izinto eziyisisekelo nezomzila. Amabhereyitha emishini abe yindinganiso yemboni isikhathi eside, enikeza imiklamo emincane kanye nomthamo omkhulu womthwalo. Emishinini eminingi yezimboni, ahlala eyisisombululo esisebenzayo nesingabizi kakhulu.
Kodwa-ke, ukuthintana ngomshini ngokungenakugwenywa kuletha ukungqubuzana, ukuguguleka, kanye nokudlidliza okuncane. Ngisho nangemiklamo ethuthukisiwe yokulayisha kusengaphambili, le miphumela ibonakala kakhulu njengoba ukulungiswa kokulinganisa kuthuthuka.
Ama-air bearings asondela ekunyakazeni ngendlela ehluke ngokuphelele. Ngokuhlukanisa izindawo ngefilimu encane yomoya ocindezelwe, aqeda ukuxhumana ngokuphelele. Lokhu kuphumela ekunyakazeni okubushelelezi kakhulu futhi cishe akugugi. Uma kuhlanganiswa nemigwaqo ye-granite, ama-air bearings azuza ekubeni yisicaba, ukuqina, kanye nokuzinza kokushisa kwe-granite substrate.
Le nhlanganisela isebenza kahle kakhulu ezindaweni zokuhlanza, izinhlelo zokubona, kanye ne-metrology enembile kakhulu, lapho ukuhambisana nokuphindaphinda kudlula umthamo womthwalo oluhlaza.
Kungani Ukuhlanganiswa Kubalulekile Ngaphezu Kwezingxenye Zomuntu Ngamunye
Inzuzo yangempelaizakhiwo ze-graniteakuveli ezindleleni zokuqondisa, ezisekelweni, noma kuma-bearings ahlukene. Kuvela lapho lezi zakhi zakhiwe njengohlelo oluhlangene.
Isisekelo somshini we-granite sinikeza isisekelo esizinzile. Imigwaqo ye-granite igcina ukunemba kokunyakaza ngokuhamba kwesikhathi. Ama-air bearings ahumusha lokho kuzinza kube ukunyakaza okungenakuphikiswana. Ndawonye, zakha uhlelo lwe-ecosystem olusekela ukunemba kunokulwa nokuphazamiseka kwemvelo.
Le ndlela yezinga lesistimu ichaza ukuthi kungani imiklamo esekelwe ku-granite isivame kakhulu kuma-CMM aphezulu, amathuluzi okuhlola i-wafer, kanye namapulatifomu okulinganisa nge-laser. Kulezi zinkambu, ukunemba akuyona into engalinganiswa kabusha—kumele kwakhiwe esakhiweni ngokwaso.
Isiphetho
Ukuqhathaniswa phakathi kwe-granite ne-cast iron, noma ama-air bearing kanye nama-mechanical bearing, akuseyona indaba yokukhetha. Kubonisa ushintsho olubanzi endleleni imishini yokunemba eklanywa futhi ihlolwe ngayo.
Njengoba izidingo zokusebenza zikhuphuka, izinto zokwakha nezakhiwo ezinikeza ukuzinza okungokwemvelo, ukumanzisa, kanye nokuvumelana kokushisa zithola inzuzo ecacile.izisekelo zomshini, esekelwa ubuchwepheshe bokuthwala umoya, iba yisisekelo sesizukulwane esilandelayo semishini yokunemba.
Kubakhiqizi abagxile ekunembeni kwesikhathi eside kunokuba kube lula isikhathi esifushane, lezi zinqumo zibumba ikusasa lobunjiniyela bokunemba.
