Ekufuneni ukunemba okuphelele, ukukhethwa kwezinto zokwakha amapulatifomu kanye nezisekelo zemishini kuyisinqumo esithinta zonke izigaba zenqubo yokukhiqiza. Njengoba izimboni ezifana nokukhiqiza ama-semiconductor, ubunjiniyela bezindiza, kanye ne-metrology ephezulu zicindezela imingcele yalokho okungenzeka ngokomzimba, isidingo samapulatifomu azinzile, athembekile, futhi anembile asikaze sibe phezulu. Ngokwesiko, insimbi ephonswe yayiyinkosi engenakuphikiswa yesitolo semishini, kodwa ukukhuphuka kwe-granite kanye nokuvela kwe-ceramics ethuthukisiwe kudale indawo eyinkimbinkimbi yokukhetha. Lesi sihloko sinikeza ukujula okujulile ezicini, izinzuzo, kanye nokusetshenziswa okuhle kwamapulatifomu e-granite, i-ceramic, kanye ne-cast iron, okunikeza umhlahlandlela ophelele wabakhiqizi abafuna izixazululo ezinhle kakhulu zezidingo zabo zokunemba.
Insimbi ephothiwe ibilokhu iyizinto eziyisisekelo embonini yamathuluzi omshini iminyaka engaphezu kwekhulu, futhi ngesizathu esihle. Amandla ayo ayinhloko atholakala ekusebenzeni kwayo okuhle kakhulu kanye nekhono lokuphothwa ezimweni eziyinkimbinkimbi nge-ribbing yangaphakathi ukuze kube nokuqina okwengeziwe. Insimbi ephothiwe empunga, ikakhulukazi, iyaziswa ngezakhiwo zayo zokudambisa ukudlidliza, eziphakeme kunezensimbi. Kodwa-ke, insimbi ephothiwe ayinazo izinkinga zayo. Ingaphansi kokucindezeleka kwangaphakathi ngesikhathi senqubo yokuphothiwe, okungaholela ekungazinzini kobukhulu ngokuhamba kwesikhathi uma ingafakwanga kahle noma iphathwe ngokushisa. Ngaphezu kwalokho, insimbi ephothiwe isengozini yokugqwala futhi idinga ukulungiswa njalo ukuze kuvinjelwe ukugqwala. Emongweni wokukhiqiza kwanamuhla okunembile kakhulu, ukuhanjiswa kokushisa kwensimbi ephothiwe nakho kungaba yinkemba esika nhlangothi zombili; ngenkathi ikhipha ukushisa ngokushesha, isabela ngokushesha ekushintsheni kokushisa kwemvelo, okuholela emaphutheni angaba khona ngobukhulu.
Ukushintshela ku-granite njengento ekhethwayo yamapulatifomu okunemba kwaqala emashumini eminyaka edlule futhi kusukela lapho sekuyinto ejwayelekile embonini ye-metrology kanye nezicelo ze-CNC ezinembile kakhulu. I-granite yemvelo, ikakhulukazi izinhlobo ezifana ne-black diabase, inikeza izinga lokuzinza okulinganayo okungenakufinyeleleka ngezinsimbi. Ngenxa yokuthi i-granite ibilokhu inongwa umhlaba eminyakeni eyizigidi, cishe ayinazo izingcindezi zangaphakathi. Uma isihlanganiswe ngokunembile ibe yi-flatness ethile, igcina leyo geometry ngokuhambisana okuphawulekayo. I-granite nayo ayinamakhemikhali futhi ayinazo izimbobo, okwenza ivikeleke ekugqwaleni futhi imelana kakhulu namakhemikhali nama-coolant asetshenziswa ekukhiqizeni. I-coefficient yayo ephansi yokwanda kokushisa kanye nobukhulu obuphezulu bokushisa kwenza iqine kakhulu ezindaweni lapho ukulawulwa kokushisa kuyinselele. Kumapulatifomu angaguquki kanye nezindiza zokubhekisela, i-granite ihlala iyindinganiso yegolide.
Eminyakeni yamuva nje, izinto zobumba ezithuthukisiwe ziye zavela njengendlela engcono kakhulu yokusebenza kwezicelo zokunemba ezidinga kakhulu. Izinto ezifana ne-alumina (i-aluminium oxide) kanye ne-silicon carbide zinikeza inhlanganisela yezakhiwo ezidlula i-granite kanye ne-cast iron ezindaweni ezithile. Izinto zobumba ziqinile kakhulu—ngokuvamile ziqine kabili kunensimbi—futhi zinobunzima obukhulu kakhulu, okwenza zimelane kakhulu nokuguguleka nokuguquka. Zine-coefficient ephansi kakhulu yokwanda kokushisa, ngisho nangaphansi kwe-granite, futhi zingasebenza emazingeni okushisa aphezulu kakhulu ngaphandle kokulahlekelwa ukunemba kwazo. Inzuzo eyinhloko yamapulatifomu obumba yisilinganiso sawo sokuqina-kuya kwesisindo, okwenza afaneleke kakhulu ekuhambiseni izingxenye emishinini enesivinini esikhulu, enembile. Kodwa-ke, izindleko eziphezulu zezinto zokusetshenziswa kanye nobunzima bokwenza izinto zobumba kusho ukuthi ngokuvamile zigcinelwe izinhlelo zokusebenza ezikhethekile lapho kungekho okunye okwanele.
Ukukhetha phakathi kwalezi zinto ezintathu kuvame ukwehla ekulinganiseni ukusebenza, izindleko, kanye nezidingo ezithile zohlelo lokusebenza. Ezisekelweni zemishini emikhulu, enzima lapho kudingeka khona izakhiwo zangaphakathi eziyinkimbinkimbi, insimbi ecijile ihlala iyisinqumo esisebenzayo nesingabizi kakhulu, uma nje izimo zemvelo zilawulwa kahle. Kumalebhu okukala imitha, iziteshi zokuhlola, kanye nemishini ye-CNC enembile kakhulu lapho ukuzinza kwesikhathi eside kanye nokumelana nemvelo kubaluleke kakhulu, i-granite iyona ephumelela kakhulu. Amandla ayo okuhlinzeka ngendiza yokubhekisela ezinzile, eyisicaba enokulungiswa okuncane kwenza kube yingxenye ebalulekile yokuqinisekiswa kwekhwalithi yesimanje. Okwamanje, ezinhlelweni zokunyakaza ezinembile kakhulu embonini ye-semiconductor kanye ne-optical, lapho kudingeka khona ukusheshisa okuphezulu kanye nokunemba kwe-sub-micron, i-ceramics ethuthukisiwe inikeza umkhawulo wokusebenza odingekayo.
Ukuhlanganiswa kwalezi zinto ezakhiweni ezihlanganisiwe kungenye indlela ekhulayo embonini. Abakhiqizi bahlanganisa ngokwengeziwe amandla ezinto ezahlukene ukudala amapulatifomu anikeza okungcono kakhulu emhlabeni wonke. Isibonelo, umshini ungase ube nesisekelo esikhulu segranite sokuqina kanye nokunciphisa ukudlidliza, kuhlanganiswe nezindlela zokuqondisa ze-ceramic zokunyakaza okusheshayo kanye nokumelana nokuguguleka. Le ndlela ye-modular ivumela ukwenziwa ngcono kwengxenye ngayinye ngokusekelwe emsebenzini wayo othize, okuholela emishinini enembile kakhulu, ekhiqiza kakhulu, futhi ethembekile kakhulu. Ukwanda kokuphonswa kwamaminerali—okuyinhlanganisela yama-granite aggregates kanye ne-epoxy resin—kuhlinzeke futhi ngebhuloho phakathi kwegranite yemvelo kanye nensimbi ephonswe, okunikeza izinzuzo eziningi zegranite ngokuguquguquka komklamo wokuphonswa.
Njengoba sibheke ikusasa lokukhiqiza ngokunemba, indima yalezi zinto izoba yinto ebaluleke kakhulu. Ukuthuthukiswa okuqhubekayo kwezindlela ezintsha zokwenziwa kwe-ceramic kanye nokulungiswa kwamasu okucubungula i-granite kucindezela imingcele yalokho okungafezwa. Ngesikhathi esifanayo, ukuhlanganiswa kobuchwepheshe bedijithali kanye nezinhlelo zezinzwa kuvumela ukuqapha ngesikhathi sangempela ukuzinza kwepulatifomu kanye nezimo zemvelo. Le ndlela eqhutshwa idatha yokukhiqiza incike ekubikezelweni nasekuthembekeni kwepulatifomu ebonakalayo, futhi ukukhetha izinto kuyisinyathelo sokuqala sokuqinisekisa lokho kuthembeka. Kungakhathaliseki ukuthi ukuzinza kwasendulo kwe-granite, amandla aguquguqukayo ensimbi ephonswe, noma ukusebenza kwe-ceramics okuphambili, lezi zinto zingabalingani abathule ekudalweni kwezimangaliso zobuchwepheshe ezithuthuke kakhulu emhlabeni.
Ekuphetheni, isimo samapulatifomu okukhiqiza ngokunemba siwukuvela nokuthuthuka okuqhubekayo. Ngokuqonda izakhiwo ezihlukile kanye nokushintshana kwe-granite, i-ceramic, kanye ne-cast iron, abakhiqizi bangenza izinqumo ezinolwazi ezihambisana nemigomo yabo ethile yokunemba. Ukutshalwa kwezimali epulatifomu esezingeni eliphezulu kuwukutshalwa kwezimali esikhathini esizayo senqubo yokukhiqiza, okunikeza isisekelo esiqinile lapho konke ukunemba kanye nekhwalithi kwakhelwe khona. Njengoba isidingo sokunemba siqhubeka nokukhula kuzo zonke izinhlaka zezimboni, ukubaluleka kokukhetha izinto ezifanele zomsebenzi kuzobonakala kakhulu, okwenza lezi zixazululo ezithuthukisiwe zibe yisihluthulelo sokuvula izinga elilandelayo lobuhle bezimboni.
Ukuqhathaniswa kobuchwepheshe kwalezi zinto kudlulela nasekuziphatheni kwazo ngaphansi kwemithwalo enamandla. Ekusebenzeni ngesivinini esikhulu, ikhono leplatifomu lokususa amandla nokumelana nokuzwakala libalulekile. Ngenkathi i-granite ingcono kakhulu ekucindezeleni ukudlidliza okunemvamisa ephansi, izinto zobumba ezithuthukisiwe zingaklanywa ukuze zibe nemvamisa ethile yokudlidliza engaphandle kwebanga lokusebenza komshini. Lokhu kuvumela isivinini esikhulu nakakhulu kanye nokusheshisa ngaphandle kokuphazamisa ukunemba. Insimbi ephothiwe, yize ikwazi ukumanzisa, ngezinye izikhathi ingahlushwa "ukukhala" kuma-frequency athile, okumele kubhekwe ngokuklama ngokucophelela kanye nokusetshenziswa kwezinto ezengeziwe zokumanzisa. Ngakho-ke, ucwaningo lokuhlaziywa kwe-modal kanye ne-structural dynamics luyingxenye ebalulekile yenqubo yokuklama yanoma iyiphi iplatifomu enembayo ephezulu, kungakhathaliseki ukuthi ikhethiwe yiphi impahla.
Ngaphezu kwalokho, umthelela wemvelo kanye nokusimama kwalezi zinto kuba yinto ebalulekile kakhulu kubakhiqizi. I-granite yemvelo iyisinqumo esiqhubekayo, njengoba iyisisetshenziswa semvelo esidinga ukucutshungulwa okuncane uma kuqhathaniswa nokukhiqizwa kwezinsimbi nezinto zobumba ezidinga amandla amaningi. Ukuqina kwayo okukhulu kusho nokuthi izingxenye ze-granite zingasetshenziswa kabusha noma zisetshenziswe kabusha ekupheleni kokuphila komshini, okunciphisa kakhulu ukuthinteka kwayo kwezemvelo. Insimbi ephothiwe, yize ingaphinde isetshenziswe, idinga amandla amakhulu okuncibilikisa nokuphotha. Izinto zobumba, nakuba zihlala isikhathi eside, kunzima ukuziphinda zisetshenziswe futhi zidinga amazinga okushisa aphezulu ekukhiqizweni kwazo. Njengoba imithetho yomhlaba wonke mayelana nokukhishwa kwekhabhoni kanye nemfucuza iqhubeka nokuqina, iphrofayili yokusimama kwezinto zokukhiqiza izodlala indima enkulu nakakhulu enkambisweni yokwenza izinqumo.
Imiphumela yezomnotho yokukhetha into eyodwa kunenye nayo iyinkimbinkimbi. Ngenkathi izindleko zokuqala zepulatifomu ye-ceramic zingaba ziphindwe kaningana kuneze-granite noma insimbi ephonswe, amathuba okwanda kokukhiqiza kanye nokugcinwa okuncishisiwe kungaholela ezindlekweni eziphansi zobunikazi phakathi nesikhathi somshini. Isibonelo, embonini ye-semiconductor, lapho ngisho nemizuzu embalwa yokungasebenzi ingabiza izigidi zamaRandi, ukuthembeka kanye nokusebenza kwesigaba sokunyakaza kwe-ceramic kungathethelela kalula intengo yaso ephezulu. Ngokuphambene nalokho, esitolo semishini esijwayelekile, ukusebenza kahle kwezindleko kanye nokuguquguquka kwensimbi ephonswe noma ukuzinza kwesikhathi eside kwe-granite kungaba yisinqumo esifanele kakhulu. Abakhiqizi kumele bahlole ngokucophelela imigomo yabo yokukhiqiza ethile kanye nemikhawulo yesabelomali ukuze banqume ukuthi iyiphi impahla enikeza imbuyiselo engcono kakhulu ekutshalweni kwezimali.
Izinqubo zokukhiqiza nokuqeda lezi zinto nazo zikhethekile kakhulu. I-granite idinga ukugoqwa ngokunemba ochwepheshe abanekhono ukuze kufezwe ukuthamba okudingekayo kanye nokuphela kobuso. Insimbi ephothiwe idinga imishini ngokucophelela kanye nokuklwebha ngesandla ukuqinisekisa ukunemba kwezindawo zayo zokufaka. I-ceramics, ngenxa yobunzima bayo obukhulu, ingakhiwa kuphela ngomshini kusetshenziswa amathuluzi edayimane kanye nezinqubo zokugaya ezikhethekile. Ukutholakala kwabasebenzi abanekhono kanye nemishini edingekayo yokucubungula lezi zinto nakho kungathonya ukukhethwa kwezinto. Njengoba imboni iqhubekela phambili ekuzenzekeleni okwengeziwe, ukuthuthukiswa kwezinhlelo zokubopha nokugaya zamarobhothi kusiza ekuthuthukiseni ukuhambisana nokunciphisa izindleko zokukhiqiza amapulatifomu anokunemba okuphezulu kuzo zonke izinto ezintathu.
Uma sibheka phambili, ukuthuthukiswa kwezinto ezintsha ezihlanganisiwe ezihlanganisa izakhiwo ezinhle kakhulu ze-granite, i-ceramics, kanye nezinsimbi kuyindawo ethembisayo yocwaningo.
