Amapuleti Omphezulu We-Granite vs. Insimbi Ecijile: Ukukhetha Ipulatifomu Efanele Izidingo Zakho Zokulinganisa I-Metology

Esimweni esidinga kakhulu sokukhiqiza ngokunemba kanye nokulawula ikhwalithi, ukukhetha ipuleti lobuso kuyisinqumo esiyisisekelo esithinta kakhulu ukunemba, ukuthembeka, kanye nokusebenza kahle kwemisebenzi ye-metrology. Lezi zindawo ezisicaba ngokucophelela zisebenza njengedatha eyinhloko yokuhlola, ukwakheka, kanye nemisebenzi yokulinganisa, okwenza ukwakheka kwazo kube yinto ebalulekile. Sekungamashumi eminyaka, impikiswano phakathi kwamapuleti obuso be-granite kanye nensimbi ecijile ibilokhu ibalulekile kochwepheshe be-metrology, into ngayinye iveza izinzuzo kanye nokucatshangelwa okuhlukile. Ukuqonda izici ezicacile zazo zombili kubalulekile ekukhetheni ipulatifomu efanele ehambisana nezidingo ezithile zokusebenza kanye nembuyiselo yesikhathi eside ekutshalweni kwezimali.

Amapuleti ensimbi ehlanganisiwe anomlando omude nohlukile ku-metrology, angaphambi kokusetshenziswa kabanzi kwe-granite. Ukuqina kwawo kanye nezakhiwo zawo ezihlukile kuwenze aba yinto ebalulekile ezindaweni eziningi zezimboni, ikakhulukazi lapho ukusetshenziswa okunzima kanye nokulungiswa kubaluleke kakhulu.

Enye yamandla ayinhloko ensimbi ephonswe itholakala emandleni ayo aphezulu okusebenza kanye nokumelana nokushayisana. Ngokungafani ne-granite, engaqhekeka noma iqhekeke lapho ishayisana kakhulu, insimbi ephonswe iqinile kakhulu futhi ingamelana nokucindezeleka okukhulu kokusebenza. Lokhu kwenza amapuleti ensimbi ephonswe afaneleke kakhulu ezindaweni lapho izingxenye ezisindayo zivame ukuphathwa khona, noma lapho kunengozi ephezulu yokuwa noma ukushayisana ngengozi. Ukuqina kwayo okungokwemvelo kuqinisekisa ukuthi ipuleti lingabekezelela ubunzima besitezi sokukhiqiza esiguquguqukayo ngaphandle kokubeka engcupheni ubuqotho besakhiwo saso.

Insimbi ephothiwe kulula kakhulu ukuyishicilela kune-granite, okuvumela ukuhlanganiswa okuqondile kwezici ezahlukahlukene ngqo epuletini. Lokhu kufaka phakathi izikhala ze-T, izimbobo ezinezintambo, kanye nezindlela zokubopha, ezibalulekile ekuqiniseni izinto zokusebenza kanye nezinto ezisetshenziswayo ngesikhathi sokuhlolwa noma ukuhlanganiswa. Lokhu kuvumelana nezimo kwenza amapuleti obuso bensimbi ephothiwe abe nokuguquguquka kakhulu ezinhlelweni zokusebenza ezidinga ukulungiswa kabusha njalo noma ukusetshenziswa kwamathuluzi akhethekile. Ngaphezu kwalokho, ikhono lomshini wokushicilela insimbi livumela ukwenza ngokwezifiso okunembile ukuze kuhlangatshezwane nezidingo zokusebenza ezihlukile, okunikeza izinga lokuguquguquka i-granite engenakukwazi ukulilinganisa kalula.

Inzuzo ephawulekayo yamapuleti obuso bensimbi ephonswe ukuthi ayakwazi ukulungiswa. Ngokuhamba kwesikhathi, ngisho nezindawo eziqinile kakhulu zingaguga noma zonakale. Lapho ipuleti lensimbi ephonswe liguga noma ukuba yisicaba kwalo kubohla, livame ukuklwejwa kabusha noma ukuklwejwa kabusha ochwepheshe abanekhono ukuze kubuyiselwe ukunemba kwalo kwasekuqaleni. Leli khono lokuvuselelwa landisa kakhulu isikhathi sokuphila kwepuleti lensimbi ephonswe, okwenza kube inketho eqhubekayo nengabizi ngokuhamba kwesikhathi, ikakhulukazi kumayunithi amakhulu, abiza kakhulu. Lokhu kulungiswa kuqhathaniswa ne-granite, lapho, uma seyonakele kakhulu noma igugile ngaphezu kwephuzu elithile, ngokuvamile idinga ukushintshwa.

Insimbi ephothiwe inomoya wokushisa ophezulu uma kuqhathaniswa ne-granite. Nakuba lokhu kungaba yiphutha maqondana nokuzinza kokushisa (njengoba kuxoxwe kamuva), kungaba wusizo nasezimweni ezithile lapho kudingeka khona ukulingana kokushisa okusheshayo kulo lonke ipuleti, noma lapho ipuleti idinga ukuqeda ukushisa okukhiqizwa yi-workpiece noma indawo ngokushesha.

Amapuleti omhlaba we-granite aqala ukuvelela ngesikhathi seMpi Yezwe II, ekuqaleni esikhundleni sensimbi, kodwa ngokushesha afakazela izimfanelo zawo ze-metrological eziphakeme. Namuhla, ayindinganiso yemboni yezicelo ezinembile kakhulu, ethandwa ngenxa yezakhiwo zawo zangaphakathi ezinciphisa ukungaqiniseki kokulinganisa.

Isici esidumile kakhulu se-granite ku-metrology ukuzinza kwayo okuvelele kobukhulu, ikakhulukazi ngenxa ye-coefficient yayo ephansi kakhulu yokwanda kokushisa (i-CTE). I-CTE ye-Granite cishe ingxenye eyodwa kwezintathu kuneyensimbi ephonswe (isb., 4.6 x 10⁻⁶/°C ye-granite uma kuqhathaniswa no-11 x 10⁻⁶/°C yensimbi ephonswe). Lokhu kusho ukuthi amapuleti e-granite awathinteki kakhulu ekukhuleni nasekuncipheni kokushisa okubangelwa ukushintshashintsha kwezinga lokushisa. Emalabhorethri e-metrology alawulwa izinga lokushisa, lesi sici siqinisekisa ukuthi indawo yokubhekisela ihlala ithambekele futhi inembile njalo, kunciphisa amaphutha okushisa angathinta kakhulu ukunemba kokulinganisa. Lokhu kuzinza kokushisa okungokwemvelo kuyitshe lesisekelo le-metrology yokunemba okuphezulu, enikeza idatha ethembekile ngisho nokushintsha okuncane kwemvelo.

Ukulinganisa ngokunemba kusengozini enkulu yokudlidliza, okungangenisa umsindo nokungazinzi enqubweni yokulinganisa. I-Granite inezakhiwo ezinhle kakhulu zokudambisa ukudlidliza kwemvelo ngenxa yesakhiwo sayo esiqinile, esikristalu. Imunca futhi ichithe ngempumelelo ukudlidliza komshini, idale

Indawo ethule yezinsimbi ezibucayi. Ngokuphambene nalokho, insimbi ephonswe ivame 'ukukhala' noma ukudlidliza kakhulu, ngokuvamile idinga ezinye izinsimbi ezikhethekile zokudambisa ukuze kusetshenziswe i-metrology ephezulu. Leli khono eliphakeme lokudambisa le-granite libalulekile ekufezeni izilinganiso eziphindaphindwayo nezinembile, ikakhulukazi lapho kukhulunywa ngezinsimbi ezibucayi noma kwenziwa izilinganiso emazingeni angaphansi kwe-micron.

I-granite ilukhuni kakhulu kunensimbi ephothiwe, ngokuvamile ibonisa ubulukhuni obungu-Mohs obungu-6 kuya ku-7. Lobu bulukhuni obuphakeme buholela ekumelaneni nokuguguleka okungavamile, okwenza amapuleti e-granite amelane kakhulu nokuklwebheka nokuklwebheka okuvela ezingxenyeni ezishelelayo ebusweni bawo. Ngokunakekelwa okufanele, ipuleti lobuso le-granite lingagcina ukunemba kwalo amashumi eminyaka, linikeze isikhathi eside kakhulu sokuphila. Ngaphezu kwalokho, i-granite ayinazo izimbobo, ayina-magnetic, futhi ayinamakhemikhali. Lokhu kusho ukuthi ayigodli ngokuphelele ekugqwaleni nasekugqwaleni okuvela kumafutha, ama-coolant, noma umswakama, okususa isidingo sokugcinwa njalo njengokugcoba ngamafutha okudingwa yi-cast iron. Impahla yayo engeyona i-magnetic nayo inenzuzo ekuhloleni izingxenye emikhakheni ye-elekthronikhi noma yezindiza, lapho ukuphazamiseka kwamagnetic kungaba yinkinga khona.

Izidingo zokunakekelwa kwamapuleti obuso be-granite ziphansi kakhulu. Ukusula okulula ngesihlanzi esikhethekile ngokuvamile yikho kuphela okudingekayo ukugcina ubuso buhlanzekile. Ukungabikho kokugqwala kanye nokuqina kwezinto kusho ukuthi amapuleti e-granite awagobeki ngokuhamba kwesikhathi ngenxa yokukhululeka kokucindezeleka kwangaphakathi, ngokungafani nensimbi engadingi ukuklwejwa kabusha noma ukuphindaphindwa ukuze kulungiswe ukuphambuka. Lesi sici sokunakekelwa okuphansi sinikeza kakhulu ukusebenza kahle kwezindleko zesikhathi eside kwamapuleti e-granite.

Ukuze wenze isinqumo esinolwazi, kubalulekile ukuqhathanisa amapuleti omhlaba we-granite kanye nensimbi ephonswe ngensimbi ngokusebenzisa imingcele eminingana ebalulekile ye-metrological kanye neyokusebenza.
