Ekufuneni okungapheli kokwenza kahle ekukhiqizeni, lapho ukubekezelelana kulinganiswa ngama-micron futhi ikhwalithi ingaxoxiswana, isisekelo sokunemba sivame ukuba semathuluzi ayisisekelo kakhulu. Enhliziyweni yawo wonke amalabhorethri okulawula ikhwalithi, isitolo semishini, kanye nomugqa wokuhlanganisa kukhona isinqumo esibalulekile: ukukhetha indiza yokubhekisela. Sekungamashumi eminyaka, imboni ithembele ezintweni ezimbili eziyinhloko ukuze isebenze njengesisekelo sokunemba: i-granite yemvelo kanye nensimbi ephonswe ngensimbi ephezulu. Lawa Mapulatifomu Okulinganisa Okuhlala Isikhathi Eside awawona nje ama-surface angasebenzi; angabavikeli abasebenzayo bekhwalithi, abaqinisekisa ukuthi yonke into ekhiqizwayo ihlangabezana nezimfuneko eziqinile ezifunwa ubunjiniyela besimanje.
Njengoba izimboni zithuthuka, kusukela esikalini esikhulu sokukhiqiza imishini esindayo kuya ekuqondeni okuncane kakhulu kokwenziwa kwe-semiconductor, isidingo sezisekelo zokulinganisa ezizinzile, ezinembile, nezihlala isikhathi eside asikaze sibe sikhulu kangaka. Lesi sihloko sihlola izindima ezihlukile ze-granite ne-cast iron endaweni yezimboni yesimanje, sihlaziya izakhiwo zazo zezinto ezibonakalayo, ukusetshenziswa kwazo ekulinganisweni okunembile kakhulu, nokuthi kungani zihlala ziyisinqumo esifanele sokusekela imishini esindayo neyinkimbinkimbi kakhulu emhlabeni.
Isayensi Yezinto Zokuzinza: I-Granite vs. I-Cast Iron
Ukuze uqonde ukuthandwa okuqhubekayo kwalezi zinto ezimbili, umuntu kufanele abheke i-physics yezakhiwo zazo zama-athomu. Kokubili i-granite ne-cast iron kunikeza izinzuzo ezihlukile ezenza zifanelekele i-metrology enembile, kodwa zithola ukuzinza ngezindlela ezahlukene.
I-Granite Yemvelo: I-Inert Standard
I-granite, ikakhulukazi i-granite emnyama esezingeni eliphezulu (evame ukutholakala ezinkwalini ezaziwa ngokuzinza okucolekile), iyaziswa ngokuqina kwayo okukhulu. Njengoba yakhiwe eminyakeni eyizigidi ngaphansi kokushisa okukhulu kanye nengcindezi, ukucindezeleka kwangaphakathi ngaphakathi kwetshe cishe akukho. Le nqubo yokuguga yemvelo isho ukuthi ipulatifomu ye-granite enembile ngeke igobe noma iphenduke ngokuhamba kwesikhathi.

Njengoba yakhiwe eminyakeni eyizigidi ngaphansi kokushisa okukhulu kanye nengcindezi, ukucindezeleka kwangaphakathi ngaphakathi kwetshe cishe akukho. Le nqubo yokuguga yemvelo isho ukuthi ipulatifomu ye-granite enembile ngeke igobe noma iphenduke ngokuhamba kwesikhathi.
Enye yezinzuzo ezibaluleke kakhulu ze-granite ukuthi i-coefficient yayo ephansi yokwanda kokushisa ingashintshashintsha. Endaweni yokusebenza lapho amazinga okushisa engashintshashintsha khona, insimbi noma insimbi inganda noma inciphe, ishintshe ukuba yisicaba kobuso. Nokho, i-granite ihlala ingashintshi ngokuphawulekayo. Ngaphezu kwalokho, njengezinto ezingezona ezensimbi, ayigodli ukugqwala nokugqwala. Ezindaweni lapho izinto zokupholisa, uwoyela, noma umswakama zivame khona, ubuso be-granite ngeke bubole noma bubole, okuqinisekisa impilo ende yenkonzo. Futhi ayinamandla kagesi, okwenza kube ukuphela kokukhetha kokulinganisa izingxenye ezizwela amandla kazibuthe, njengalezo ezitholakala kuma-elekthronikhi noma kumadivayisi ezithombe zezokwelapha.
Insimbi Ebunjiwe: Ihhashi Elisebenzayo Eliqinile
Nakuba i-granite inikeza ukuzinza ngenxa yokungangeni, insimbi ephonswe inikeza amandla ngenxa yokuqina. Amapulatifomu e-Cast Iron aziwa ngomthamo wawo ophezulu wokuthwala umthwalo. Isakhiwo sangaphakathi sensimbi ephonswe, esibonakala ngama-graphite flakes ngaphakathi kwe-ferrite noma i-pearlite matrix, siyinika izakhiwo ezimangalisayo zokudambisa. Lokhu kusho ukuthi insimbi ephonswe isebenza kahle kakhulu ekumunceni nasekuqedeni ukudlidliza.

Lokhu kusho ukuthi insimbi ephonswe isebenza kahle kakhulu ekumunceni nasekuqedeni ukudlidliza.
Ngokwesimo seMishini Enzima, lapho ibhlogo elikhulu lenjini noma i-turbine blade lingabekwa etafuleni lokulinganisa, ukuqina kwensimbi ephonswe kubalulekile. Ingasekela isisindo esikhulu ngaphandle kokugoba, iqinisekise ukuthi ukulinganisa akuphazanyiswe ukuphambuka kwepulatifomu uqobo. I-metallurgy yesimanje ithuthukise insimbi ephonswe kakhulu; ama-alloy afana ne-Meehanite kanye ne-grey iron yezinga eliphezulu (HT300) anikeza ubulukhuni obuthuthukisiwe kanye nokumelana nokuguguleka, okuvala igebe phakathi kwensimbi yendabuko nezinto zesimanje ezihlanganisiwe.
Ukulinganisa Okunembe Kakhulu: Indima Yamapuleti Omphezulu
Ipuleti elingaphezulu liyidatha eyinhloko yokulinganisa ngokunemba. Kungakhathaliseki ukuthi ukuhlolwa okulula kwengxenye esetshenzisiwe noma ukulinganiswa okuyinkimbinkimbi kwengalo yerobhothi, ukunemba komphumela kuhle kuphela njengokuqina kwepuleti.
Ngezinhlelo zokusebenza ezinembe kakhulu, ukuqeda ubuso kanye nokubekezelela ukuthamba kubalulekile. Amapuleti e-granite avame ukugoqwa afinyelele esibukweni, okufeza amanani okugoba avumela ukunyakaza okungenakuphikiswana kwezinsimbi zokulinganisa. Lokhu kubalulekile uma usebenzisa amazinga e-elekthronikhi noma ama-autocollimator, lapho ngisho nokuhudula okuncane kungathinta ukufunda. Ukuqina kwe-granite kusho nokuthi imelana nokuklwebheka. Uma ingxenye yensimbi iwa epuletini le-granite, kungenzeka kakhulu ukuthi yonakalise ingxenye kunepuleti, kugcinwe ubuqotho bendawo yokubhekisela.
Kodwa-ke, amapuleti ensimbi aqinile ahlala emazingeni okulinganisa aguquguqukayo. Umphumela "wokusonta"—ukukhangana kwama-molecule okuvumela amabhlogo e-gauge ukuthi anamathele ndawonye—ungatholakala kumapuleti ensimbi asezingeni eliphezulu, isici esivame ukusetshenziswa kuma-laboratories okulinganisa. Ngaphezu kwalokho, ubuso bepuleti lensimbi ensimbi bungaphindwa bube khona noma "bukhuhlwe kabusha" uma buguga, okwandisa isikhathi salo sokuphila kakhulu. Lokhu kulungiswa kabusha kwenza insimbi ensimbi ibe ukukhetha okungabizi kakhulu kuma-workshop amatasa lapho ipulatifomu isetshenziswa khona nsuku zonke.
Ilungele Imishini Esindayo: Ubuqotho Besakhiwo kanye Nokuthwala Umthwalo
Uma sisuka egumbini lokuhlola siya phansi efektri, izidingo zamapulatifomu okulinganisa ziyashintsha kusukela ekubeni yisicaba okumsulwa kuya ekubeni nobuqotho besakhiwo. Yilapho-ke isici esithi “Imishini Enzima” sesihloko sethu sisebenza khona.
Ukusekela Ama-Giants Ezimboni
Emkhakheni wezindiza kanye namandla, abakhiqizi basebenzelana nezingxenye ezingaba nesisindo samathani amaningana. Ibhokisi legiya lomoya noma i-jet engine casing idinga ipulatifomu yokulinganisa engagcini nje ngokuba yithafa kodwa futhi ephilile ngokwanele ukuthwala umthwalo ngaphandle kokuguquka unomphela. Lapha, ama-Cast Iron Platforms avame ukuba phambili. Amandla okucindezela ensimbi ephonswe kakhulu avumela ukwakhiwa kwamatafula amakhulu anezakhiwo eziyinkimbinkimbi ze-ribbing (ngokuvamile imiklamo ye-honeycomb noma i-box-rib) ezikhulisa ukuqina ngenkathi zinciphisa isisindo.

Lezi zingxenyekazi zivame ukusebenza njengesisekelo seMishini Yokulinganisa Ehlanganisiwe (ama-CMM). Kuma-CMM amakhulu, isisekelo se-granite noma sensimbi kumele sihlale sizinzile ngenkathi ikhanda lomshini lihamba ngesivinini esikhulu. Izakhiwo zokunciphisa ukudlidliza kwensimbi ephonswe zizuzisa kakhulu lapha, zihlukanisa i-probe yokulinganisa ekudlidlizeni phansi okubangelwa ama-forklift aseduze noma imishini yokucindezela.
I-Granite Ehambayo
Ngakolunye uhlangothi, i-granite isetshenziswa kakhulu njengengxenye yesakhiwo ezingxenyeni ezihambayo zemishini esindayo. Ngenxa yokuthi i-granite ilula kunensimbi ngenxa yokuqina okufanayo, ivame ukusetshenziselwa amabhuloho ahambayo ama-CMM asheshayo. Lokhu kunciphisa isisindo esihambayo, okuvumela ukusheshisa okuphezulu kanye nomthamo ngaphandle kokulahlekelwa ukunemba. Isici "sokwanda okungenalutho" se-granite siqinisekisa ukuthi i-geometry yomshini ihlala ingaguquki ngisho noma ama-motor ekhiqiza ukushisa ngesikhathi sokusebenza.

Ukuqina: Ukutshalwa Kwezimali Kwesikhathi Eside
Emkhakheni wezimboni, elithi “eshibhile” livame ukusho “okubizayo” ngokuhamba kwesikhathi. Amapulatifomu Okulinganisa Okuhlala Isikhathi Eside ayitshalomali lwesikhathi eside. Ipuleti le-granite noma lensimbi elisezingeni eliphezulu, uma ligcinwa kahle, lingahlala amashumi eminyaka.
Ukunakekelwa Nokunakekelwa
Ukuqina kwalezi zinkundla kuncike kakhulu ekunakekelweni. Nge-granite, isitha esiyinhloko ukushaqeka ngokomzimba kanye nokuchitheka kwamakhemikhali. Nakuba i-granite iqinile, iyaphuka. Ukushaya okubukhali kungaphula ubuso, kudale indawo ephezulu ethinta ukuba yisicaba. Ngakho-ke, kuwumkhuba ojwayelekile ukumboza amapuleti e-granite uma ungasetshenziswa nokuwahlanza ngezihlanzi ezingagugi.

Ngakho-ke, kuwumkhuba ojwayelekile ukumboza amapuleti e-granite uma ungasetshenziswa nokuwahlanza ngezihlanzi ezingagugi.
Ngensimbi ephonswe ngensimbi, isitha siwukugqwala. Naphezu kokumbozwa kwesimanje kanye nezinsimbi, insimbi izogqwala uma ingavikelwe. Uhlelo olujwayelekile lokuhlanza nokusebenzisa ungqimba oluncane lwamafutha e-防锈 (amafutha okulwa nokugqwala) lubalulekile. Kodwa-ke, njengoba kuphawuliwe ngaphambilini, ubuso bepuleti lensimbi bungabuyiselwa. Uma ipuleti le-granite lonakele, livame ukudinga ukugoqwa kabusha kochwepheshe, okungabiza kakhulu futhi kuthathe isikhathi. Uma ipuleti lensimbi lonakele, uchwepheshe onekhono angase alikhuhle alibuyisele esimweni salo lapho likhona.
Umnotho Wokunemba
Uma ukhetha phakathi kwe-granite ne-cast iron, abakhiqizi kumele bacabangele izindleko eziphelele zobunikazi. I-granite ngokuvamile inezindleko eziphezulu kusengaphambili ngenxa yobunzima bokukhanda amatshe kanye nokuntuleka kwamabhulokhi aluhlaza asezingeni eliphezulu. Kodwa-ke, ukuntuleka kwayo kokunakekelwa (akudingeki ukugcoba ngamafutha) kanye nokungagqwali kungenza kube lula ukuyisebenzisa iminyaka engaphezu kwengu-20. I-cast iron inentengo ephansi yokungena futhi kulula ukuyilungisa, okwenza ibe yintandokazi ezitolo zemishini ezisetshenziswa kabanzi.

Amathrendi Esikhathi Esizayo: Ukuvela Kwezisekelo Zokulinganisa
Njengoba sibheke ikusasa lokukhiqiza, izinto esizisebenzisela ukulinganisa nazo ziyashintsha. Sibona ukuthambekela okuya kumapulatifomu “ahlakaniphile”, lapho izinzwa zifakwa khona ngqo esakhiweni se-granite noma sensimbi ukuze ziqaphe izinga lokushisa nokudlidliza ngesikhathi sangempela. Le datha ingafakwa kusofthiwe ye-CMM ukuze ibuyisele izinguquko zemvelo, isunduze imingcele yokunemba nakakhulu.
Ngaphezu kwalokho, ukwanda kokukhiqizwa kwezengezo (ukuphrinta kwe-3D) sekuqala ukuthonya ukwakheka kwezisekelo zensimbi ecijile. Abakhiqizi manje sebengaphrinta izikhunta zesihlabathi ezinejiyomethri zangaphakathi eziyinkimbinkimbi ezazingenakwenzeka ukuzisebenzisa ngaphambili, okuholela ezisekweni zensimbi ezilula futhi eziqinile kunanini ngaphambili. Ngokufanayo, i-granite yokwenziwa (ukhonkolo we-polymer) ithola ukubambelela kwezicelo ezithile, inikeza okunye okubunjwayo esikhundleni setshe lemvelo, yize ingenakho ukuzinza kwemvelo kokuguga kwe-granite eqoshiwe.
Isiphetho
Ezweni elibaluleke kakhulu lokukhiqiza kwezimboni, ukukhetha ipulatifomu yokulinganisa kuyisinqumo esithinta zonke izici zokukhiqiza. Kungakhathaliseki ukuthi umuntu ukhetha ukuzinza okungagqwali, okumelana nokugqwala kwama-Granite Platforms noma amandla aqinile, anciphisa ukudlidliza kwama-Cast Iron Platforms, umgomo uhlala ufana: ukuphishekela iqiniso eliphelele ekulinganisweni.
Ngemishini esindayo kanye nezinhlelo zokusebenza ezinembile kakhulu, lawa mapulatifomu aqinile ahlinzeka ngesisekelo esiqinile lapho imboni yanamuhla imi khona. Bangabalingani abathule ekusunguleni izinto ezintsha, beqinisekisa ukuthi njengoba imishini yethu iba ngokushesha futhi iyinkimbinkimbi, ikhono lethu lokuyilinganisa lihlala linembile, lithembekile, futhi lihlala isikhathi eside. Njengoba amazinga omhlaba wonke ekhuphuka, indima yalezi zisekelo zekhwalithi ephezulu izobe ibaluleke kakhulu, okufakazela ukuthi esikhathini sokwenziwa kwedijithali, isisekelo esibonakalayo sekhwalithi sisabalulekile.
