Kukhona ihlaya eliqhubekayo ekukhiqizeni ngokunemba: wonke umuntu ufuna ukukhuluma nge-laser interferometer kanye nomshini wokulinganisa ohlanganisayo. Akekho ofuna ukukhuluma ngepuleti lensimbi elingaphansi kwawo.
Kodwa ochwepheshe bemishini kanye nonjiniyela abasezingeni eliphezulu asebesebenze kule mboni isikhathi eside bayazi iqiniso. Ipuleti elingaphezulu liyisisekelo. Futhi uma isisekelo siguguleka, akukho mishini yokulinganisa ebizayo phezu kwaso ezokunikeza izinombolo ongazethemba.
Lesi sihloko simayelana namapuleti ongaphezulu ensimbi ecijile — ikakhulukazi, ukuthi yini eyenza umuntu aqine ngokwanele ukubamba ukubekezelelana okunembile ezindaweni zokukhiqiza zangempela, nokuthi yini eguqula utshalomali lwama-$3,000 lube yinkinga yama-$30,000 eminyakeni emihlanu kamuva.
Kungani Insimbi Ecijile Isabusa Ezindaweni Zokukhiqiza Zangempela
Njalo eminyakeni embalwa, othile embonini ushicilela isihloko mayelana nendlela i-granite ethatha ngayo indawo yensimbi ephonswe ukuze kusetshenziswe ukulinganisa okunembile. Futhi njalo eminyakeni embalwa, ochwepheshe bemishini abanolwazi bafunda lezo zihloko, banqekuzisa ikhanda ngenhlonipho, futhi baqhubeke nokusebenzisa amapuleti abo ensimbi ephonswe.
Isizathu akusikho ukuba nenkani. Kuyifiziksi kanye nokusebenza kahle.
Insimbi ephothiwe inamandla athile okudambisa umswakama njengoba i-granite ingenawo. Lapho imisebenzi yokusika enzima isebenza eduze — ukugaya, ukugaya, i-EDM — amandla okudlidliza angabonakalisa ubuso be-granite obuqinile futhi angcolise izilinganiso eziseduze amuncwa yisakhiwo esincane sensimbi ephothiwe. Akuyona imilingo. Ama-graphite flakes ku-matrix yensimbi ephothiwe enza lokho kanye aklanyelwe ukukwenza.
Lesi sici sokunciphisa sibaluleke kakhulu ezindaweni zokukhiqiza kunasezindaweni zokuhlola ezilawulwa yisimo sezulu. Futhi izindawo zokukhiqiza yilapho iningi lokukhiqiza ngokunemba emhlabeni kwenzeka khona.
Insimbi ephothiwe nayo ingalungiswa ngezindlela i-granite engalungiseki ngazo. Uma ipuleti lobuso lensimbi ephothiwe liguga ngokungalingani, noma lidala umonakalo wendawo, uchwepheshe wemishini angaliphinda alifake - alibuyisele ezimisweni zeBanga 00 ngaphandle kokushintsha ipuleti lonke. Lokhu kwandisa impilo yepuleti lobuso lensimbi ephothiwe elenziwe kahle libe yiminyaka engama-30, 40, noma engama-50. Zama ukukhipha lokho epuletini le-granite eliye lawa.
Umdlalo Webanga: Okushiwo Yizinombolo Empeleni
Uma umhlinzeki ekucaphuna ipuleti lensimbi ephonswe, cishe njalo ucacisa ibanga - ngokuvamile iBanga 00, iBanga 0, iBanga 1, noma iBanga 2. Lawa mabanga achazwa ezindinganisweni ezifana ne-DIN 876, ASME GGGP-463C, ISO 8512, nezinye. Ukuqonda ukuthi asho ukuthini empeleni kubalulekile ekuthengeni ipuleti elifanele.
Ibanga lichaza ukubekezelelana kokuthamba — ukuphambuka okuphezulu okuvunyelwe kusuka endizeni yokubhekisela ephelele ngokwemfundiso kuyo yonke indawo yokulinganisa.
Ku-DIN 876, ukubekezelelana kubukeka kanje:
Ibanga 00: cishe ama-micron angu-2.3 ukuphambuka ngaphezu kuka-1,000mm. Ibanga 0: cishe ama-micron angu-4.6. Ibanga 1: cishe ama-micron angu-9.2. Ibanga 2: cishe ama-micron angu-18.5.
Isinyathelo ngasinye esehlayo ebangeni cishe siphinda kabili iphutha elivumelekile. Ngezinhlelo zokusebenza ezidinga ukunemba kwezinga le-micron, lokhu kubaluleke kakhulu. Ipuleti elivumela ukuphambuka okungu-18.5 microns kokuthamba — Ibanga lesi-2 — lidla cishe lonke ibhendi yakho yokubekezelela ngaphambi kokuthi uqale ngisho nokulinganisa.
Iningi lezicelo zokuhlola zezimboni lichaza iBanga 0 noma iBanga 1. IBanga 00 ligcinelwe amalebhu e-metrology, ukuhlolwa kokugcina kwezindiza, kanye nezicelo lapho isabelomali sokungaqiniseki kokulinganisa sincane. Umehluko wentengo phakathi kwamamaki ubonisa isikhathi esengeziwe kanye nekhono elidingekayo ngesikhathi sokukhiqiza, hhayi nje umehluko wokumaketha.
Yini Enquma Ngempela Ukuthi Ipuleti Lensimbi Ebunjiwe Lihlala Isikhathi Eside Kangakanani
Amapuleti ensimbi acwebezelayo awaphumeleli ngenxa yokuguga. Ayahluleka ngenxa yendlela asetshenziswa futhi anakekelwa ngayo. Nakhu okungakutsheli khona kuleli shidi lemininingwane:
Umswakama ungumbulali othule.Insimbi ephothiwe inezimbobo. Ngisho noma ifakwa uwoyela ngendlela efanele, imunca umhwamuko wamanzi ovela emoyeni omanzi ngokuhamba kwesikhathi. Lokhu kubangela izinguquko ezincane zobukhulu ezibonakala njengokulahlekelwa okuncane kokusicaba — hhayi okukhulu ngokwanele ukukubona ngesikhathi sokusetshenziswa kwansuku zonke, kodwa okwanele ukukhukhuleka ngaphandle kokubekezelela ngaphandle kwesixwayiso. Amapuleti asezindaweni ezisogwini, ezindaweni ezishisayo, noma ezindaweni zokugcina impahla ezingenawo umoya asengozini enkulu. Isixazululo asiyinkimbinkimbi: ukufakwa uwoyela njalo, izembozo zokugcina ezifanele, kanye nokuqinisekiswa kokusicaba njalo. Kodwa futhi kuvame ukweqiwa.
Ukujikeleza kwe-thermal kudala ukucindezeleka.Ipuleti eliseduze nethuluzi lomshini, indawo yokulayisha, noma ifasitela lizobhekana nokushintshashintsha kwezinga lokushisa usuku lonke. Insimbi ephothiwe iyakhula futhi inciphe ngokushisa, kanti ukushisa okungalingani - okuvamile ezindaweni zefektri - kudala ukucindezeleka okuhlukile kulo lonke ipuleti. Eminyakeni edlule, lokhu kunegalelo ekuwohlokeni kancane kancane kokuthamba. Ukulungiswa okusebenzayo: beka ipuleti lakho elingaphezulu kude nemithombo yokushisa eqondile kanye ne-gradients yokushisa, bese ulivumela lizinze ngokushisa ngaphambi kokulinganisa okubucayi.
Ukuguga kwendawo ngenxa yokuxhumana okuphindaphindiwe.Uma opharetha bakho bebeka njalo izithwali zomsebenzi endaweni efanayo epuletini, bazodala amaphethini okuguguleka asendaweni. Lokhu kuvame kakhulu kumapuleti amancane asetshenziswa njalo ekusethweni okufanayo. Ukujikeleza indawo yepuleti ngezikhathi ezithile, nokusebenzisa izithwali ezifanele ezisabalalisa umthwalo ngokulinganayo, kwandisa impilo yesevisi kakhulu.
Umonakalo womthelela.Ibhulokhi yegeyiji ewile, ukubekwa ngokunganaki kwesitendi senkomba esindayo — lokhu kudala ukugoba kanye nama-chip marks okuba amaphutha okubhekisela ejiyometriki ahlala njalo. Umonakalo womthelela ensimbini ephonswe ungalungiswa, kodwa ukulungiswa kubiza imali futhi kuthatha isikhathi. Ukuvimbela kushibhile uma kuqhathaniswa.
Ikhwalithi Yokukhiqiza Ehlukanisa Ipuleti Leminyaka Engu-20 Kulelo Leminyaka Engu-5
Akuwona wonke amapuleti ensimbi enziwe ngendlela efanayo. Ukwakheka kwezinto zokusetshenziswa, inqubo yokubumba, ukwelashwa kokushisa, kanye nokuklwebheka kokugcina konke kunegalelo ekusebenzeni kwesikhathi eside.
Ikhwalithi yezinto ezingavuthiwe ibaluleke kakhulu kunalokho abathengi abaningi abakuqaphelayo.Isakhiwo se-graphite flake ensimbini ephonswe ngensimbi — okuyinika izakhiwo zayo zokumanzisa — sincike ekwakhekeni kwensimbi kanye nezimo zokuphonswa. Ama-castings anokusatshalaliswa kwe-graphite okungalingani, avame kakhulu ukungazinzi ngobukhulu kunalawo ane-graphite encane, esatshalaliswe ngokulinganayo. Umenzi olawula inqubo yawo yokuphonswa kanye nokuthola izinto zokwakha ukhiqiza amapuleti ahambisanayo kunomuntu othenga ama-castings ezimpahla enkampanini yokusungula.
Ukwelashwa kokushisa kanye nenqubo yokuguga kubalulekile.Ama-cast iron cast anezingcindezi zangaphakathi ezivela enkambisweni yokupholisa. Ngaphandle kokwelashwa kokushisa okunciphisa ukucindezeleka okufanele, ipuleti lizoqhubeka nokushintsha ngobukhulu izinyanga noma iminyaka ngemva kokulifaka. Abakhiqizi be-premium baguga ama-cast iron abo — kungaba ngesitoreji semvelo noma nge-thermal cycling esheshayo — ngaphambi kokuba noma yikuphi ukusebenza kuqale. Lokhu kususa ukungazinzi kobukhulu ngaphambi kokuba ipuleti lifinyelele esigabeni sokuklwebha.
Inqubo yokuklwebha yilapho ulwazi lwangempela luhlala khona.Ukukhuhla ipuleti lobuso lensimbi ephonswe ngesandla ukuze lihambisane nezinga lokumelana lebanga 00 kudinga ingcweti engafunda izinto — ukuzwa ukuthi zingakanani izinto ezisuswayo, ukuqaphela ukuthi ubuso buhlangana nini nenhloso, nokuvumelanisa indlela yabo ngesikhathi sangempela ngokusekelwe empendulweni ethintekayo. Leli khono lithatha iminyaka ukulithuthukisa. Umkhiqizi onezingcweti ezineminyaka engu-25+ yesipiliyoni ukhiqiza amapuleti anokuziphatha okungcono komphetho, ukuthungwa komphezulu okuvumelanayo, kanye nokugcinwa okungcono kwesikhathi eside kwesicaba kunelena enezisebenzi eziningi ezishintshayo kanye nabasebenzi abangenalo ulwazi oluningi.
Izinqumo Zokuthola Impahla: Yimiphi Imibuzo Okufanele Uyibuze Ngaphambi Kokuthenga
Abathengi abashiswa ngamapuleti ensimbi ecijile ngokuvamile yibo abenze isinqumo sabo ngentengo kanye neshidi lemininingwane kuphela. Nansi imibuzo ebaluleke kakhulu:
Iyini inqubo yokwakheka kwezinto zepuleti kanye nokwakheka kwazo? Umhlinzeki ongakwazi ukuphendula lo mbuzo ngokucacile akalawuli inqubo yakhe yokukhiqiza ezingeni olidingayo.
Ingabe ukubumba kuncishisiwe ukucindezeleka ngaphambi kokwenza imishini? Uma impendulo ingucha noma ingacacile, ipuleti olithengayo lingase lisaphumula ngokwezinga elithile - okusho ukuthi ukuma kwalo kusashintsha njengoba lihleli phansi esitolo sakho.
Kuyini ukubekezelelana kokuthamba okukhiqizwayo kwakho, hhayi nje kuphela isilinganiso esincane esijwayelekile? Abanye abakhiqizi babamba amapuleti abo ebanga le-00 kuya ku-±1 micron ngaphezu kuka-1,000mm, hhayi isilinganiso esiphezulu se-2.3 micron esijwayelekile. Abanye bakhuhla kancane ngaphansi komkhawulo.
Iyiphi inqubo yokukrwela oyisebenzisayo — ngesandla, ngokuzenzakalelayo, noma ngokugcwele kwe-CNC? Kunezicelo ezisemthethweni zazo zonke. Kodwa uma umhlinzeki ethi ukukrwela kwe-CNC kufinyelela ikhwalithi efanayo nokukrwela ngesandla okunolwazi kwezicelo zeBanga 00, cela idatha yokukhiqiza.
Ngingasithola yini isitifiketi sokulinganisa esinokulandelela okugcwele esikhungweni sikazwelonke se-metrology? Hhayi nje isitifiketi sangaphakathi - esibuyela emuva ngochungechunge lokulinganisa olugunyaziwe luye elebhu kazwelonke.
Singakanani isikhathi sakho sokuhola ekukhiqizeni osayizi abajwayelekile nabangewona abajwayelekile? Futhi ingabe ugcina isitoko sosayizi abavamile?
Iyini inqubomgomo yakho yokubuyisela noma yewaranti uma ipuleti liphuma ekubekezeleleni noma liba nezinkinga ekuqaleni kwenkonzo?
Ukwenza Ukukhetha Okufanele Emvelweni Wakho
Ipuleti lobuso lensimbi ephonswe kahle elisebenza kahle elabhorethri ye-metrology elawulwa amazinga okushisa kungenzeka lingabi yisinqumo esifanele sendawo yokukhiqiza ematasa. Nasi uhlaka olusheshayo:
Kwamalabhorethri e-metrology namagumbi okuhlola anokulawulwa kwesimo sezulu:Cacisa iBanga 00, ukuphonswa okuncishisiwe ekucindezelekeni, ukulandeleka okugcwele kokulinganisa. Izindleko ezengeziwe ziqinisekiswa yizidingo zokunemba kanye nendawo elawulwayo.
Kwezindawo zokukhiqiza imishini ezinokudlidliza nokuguquguquka kokushisa:Ipuleti leBanga 0 ekusekelweni okufanele kokudlidliza lingase lisebenze kangcono kunepuleti leBanga 00 ekusekelweni okubi. Ibanga elifanele lemvelo libaluleke kakhulu kunebanga eliphakeme kakhulu elitholakalayo.
Ezindaweni ezilukhuni — izikhungo zangaphandle, isimo sezulu esinomswakama ezindaweni ezishisayo, izindawo zokugcina impahla ezingenayo i-conditioner:Cabanga nge-granite kune-cast iron ukuze uthole inzuzo yokumelana nomswakama. Noma sebenzisa inqubo eqinile yokulungisa i-cast iron — ukugcotshwa ngamafutha nsuku zonke, ukuhlolwa njalo kokusicaba, kanye nezembozo zokugcina lapho ingasetshenziswa.
Ngezikhungo zemfundo nokuqeqesha:Amapuleti eBanga loku-1 noma leBanga lesi-2 afanele ukufundisa amasu okulinganisa ayisisekelo. Ukonga imali lapha kunengqondo — izidingo zokunemba azivumelani nezindleko zemishini yeBanga lesi-00.
Umkhuba Wokunakekela Owodwa Ozokongela Imali Eningi
Uma kukhona into eyodwa kuphela oyenzayo ngendlela ehlukile ngemva kokufunda lesi sihloko, kwenze lokhu: gcina ipuleti lakho lensimbi elibunjiwe ligcotshwe ngamafutha.
Hhayi ngezikhathi ezithile. Hhayi uma ukhumbula. Njalo.
Uboya obuncane bamafutha omshini — uwoyela ofanayo ongawusebenzisa ngendlela ye-lathe noma umshini wokugaya — osetshenziswa ngendwangu engena-lint nsuku zonke noma ezimbili kudala isithiyo ekumuncweni komswakama. Kuthatha imizuzwana engama-30. Akubizi lutho. Futhi yisinyathelo esisodwa esisebenza kahle kakhulu sokulungisa ongasithatha ukuze wandise impilo yepuleti lensimbi ephonswe.
