Amapuleti Omphezulu We-Granite vs. Cast Iron: Yikuphi Okungcono Kakhulu Kwi-Metrology Lab Yakho?

Zombili izinto zisebenzele imboni yokukhiqiza iminyaka engaphezu kwekhulu, futhi zombili zinezinzuzo ezihlukile ezenza zibe ngcono kakhulu ekusetshenzisweni okuthile. Nakuba i-granite ivame ukudunyiswa njengenkosi yokuzinza nokunemba, insimbi ephonswe isalokhu iwumsebenzi onzima wephansi lezimboni. Ukuqonda izici ze-“Granite vs. Cast Iron” kubalulekile ekuqinisekiseni ukuthi ilabhorethri yakho ifakwe ithuluzi elifanele lomsebenzi, ilinganise isidingo sokunemba kwezinga le-nanometer ngokumelene nobunzima bokuhlolwa okunzima.

Amapuleti ongaphezulu e-granite, avame ukwenziwa nge-granite emnyama noma i-diabase yekhwalithi ephezulu, abe yindinganiso yegolide yezindawo zokucwaninga zesimanje ze-metrology. Ukukhanga okuyinhloko kwe-granite kusemlandweni wayo we-geological. Lawa matshe akhiwa eminyakeni eyizigidi, edlula ekugugeni kwemvelo okuqeda ngempumelelo ukucindezeleka kwangaphakathi. Lapho umenzi esika futhi epholisha ibhulokhi le-granite, asebenza ngezinto esezifinyelele isimo sokulingana okulinganayo. Lokhu kuzinza kwemvelo kusho ukuthi ipuleti le-granite limelana kakhulu nokugoba noma ukusonta ngokuhamba kwesikhathi, uma nje lisekelwa kahle.

Enye yezinzuzo ezibaluleke kakhulu ze-granite endaweni yelabhorethri ukuzinza kwayo kokushisa. Emkhakheni wokulinganisa ngokunemba, izinga lokushisa liyisitha. Izinsimbi ziyanda futhi zinciphe ngokushisa, futhi ngisho nokushintshashintsha okuncane ekushiseni okuzungezile kwelebhu kungabangela ukuthi ipuleti lensimbi likhule ngokwanele ukuze kukhishwe izilinganiso ezibucayi. I-granite ine-coefficient ephansi kakhulu yokwanda kokushisa—ephansi kakhulu kuneyensimbi ephonswe ngensimbi. Lokhu kusho ukuthi uma izinga lokushisa endaweni yakho lishintshashintsha ngamadigri ambalwa, ipuleti le-granite lizohlala lingashintshi, lilondoloze ukunemba kokufundwa kwakho. Lesi sici senza i-granite ibe ukukhetha okuhle kakhulu ezindaweni lapho ukugcina izinga lokushisa elihlala njalo (izinga lokushisa elihlala njalo) eliphelele kunzima noma kubiza kakhulu.

Ngaphezu kwalokho, i-granite iyinto engeyona eyensimbi, eletha izinzuzo ezimbili ezihlukile: ayinamagnetic futhi ayigodli ukugqwala. Endaweni yelabhorethri lapho kusetshenziswa khona izingxenye ze-elekthronikhi ezithambile noma ama-gauge magnetic, i-cast iron plate ingaletha ukuphazamiseka. I-granite, njengoba ingagqwali ngamakhemikhali, ayisoze yagqwala. Lokhu kuqeda isidingo sokusetshenziswa njalo kwamafutha okuvikela adingekayo kuma-iron plate. I-granite plate ingagcinwa ihlanzekile futhi yomile, kunciphisa ingozi yokungcolisa izingxenye ezilinganiswayo. Uma uketshezi luchitheka epuletini le-granite, lungasulwa ngaphandle kokwesaba ukugqwala, kanti ukuchitheka okufanayo epuletini le-cast iron kungaholela ekuqhekekeni nasekulimaleni okuhlala njalo uma kungaxazululwa ngokushesha.

Ukuphela kobuso bepuleti le-granite kungenye indawo lapho liphumelela khona. Ngezinqubo ezithuthukisiwe zokugoqa nokupholisha, i-granite ingafinyelela ukuqeda okufana nesibuko okubushelelezi kakhulu. Lokhu kushelela kunciphisa ukungqubuzana kwezinsimbi zokulinganisa ezishelelayo futhi kuqinisekisa ukuthi azikho iziqongo nezigodi ezincane zokubamba ukungcola noma imfucumfucu. Lapho ubuso be-granite bushaywa noma bonakaliswe—isibonelo, uma ingxenye esindayo iwela kuyo ngengozi—izinto ezisetshenziswayo zivame ukuqhekeka noma ukwakha umgodi. Okubaluleke kakhulu, akwenzi “i-burr” noma unqenqema oluphakanyisiwe oluzungeze indawo yomthelela. Ku-metrology, i-burr ephakanyisiwe iyinhlekelele ngoba iphakamisa ithuluzi lokulinganisa, okubangela ukufundwa okungamanga kuyo yonke indawo. Ukwehla kobuso be-granite kulula ukukuhlukanisa futhi ngokuvamile kunomthelela omncane ekuthambekeni kwendawo ezungezile.

Nakuba i-granite ibusa ilabhorethri enembile kakhulu, amapuleti obuso bensimbi ecijile ahlala eqinile ezindaweni zokuhlola zezimboni, amakamelo amathuluzi, kanye nezindawo zokukhiqiza ezisindayo. Impikiswano eyinhloko yensimbi ecijile ukuqina kwayo. Insimbi ecijile iyinto ethambile uma iqhathaniswa nesimo sokuphuka kwetshe. Ingamelana nokushaqeka okukhulu kanye nokushayisana ngaphandle kokuphuka. Emsebenzini omatasa lapho kubekwa khona izinto ezisindayo, ukushintshwa, noma izingxenye zensimbi etafuleni lokuhlola, ipuleti le-granite lingase liqhekeke ngaphansi kokucindezeleka. Nokho, ipuleti lensimbi ecijile lizomunca ukushaqeka.

Ukugcinwa kwensimbi ephothiwe ngokuvamile akuqondwa kahle. Nakuba kuyiqiniso ukuthi insimbi idinga ukuvikelwa ekugqwaleni, ipuleti lensimbi ephothiwe elinakekelwe kahle lingahlala amashumi eminyaka. Indlela yendabuko yokugcina la mapuleti ihilela ukugcina ifilimu elincane lamafutha ebusweni. Lo mafutha awagcini nje ngokuvimbela ukugqwala kodwa futhi asebenza njenge-lubricant yezingxenye ezishelelayo. Ngaphezu kwalokho, ubuso bepuleti lensimbi ephothiwe buvame "ukuklwejwa" ngesandla. Le nqubo yesandla idala iphethini yamapokhethi amancane ebusweni. Lawa mapokhethi awawona amaphutha; ayasebenza. Asebenza njengezindawo zokugcina ukugcoba futhi abamba noma yiluphi uthuli noma i-swarf encane engase ibe khona, okuvimbela ukuthi ingaphazamisi ukulinganisa. Lesi senzo "sokusonta" sivumela uhlobo oluthile kakhulu lwempendulo ethintekayo ethandwa ochwepheshe abaningi bemishini nabahloli abangochwepheshe.

Enye inzuzo ephawulekayo yensimbi ephonswe ukuthi iyalungiseka. Uma ipuleti lensimbi eliphonswe liguga noma lonakele, lingakhuhlwa kabusha noma ligaywe kabusha ukuze kubuyiselwe ukunemba kwalo kwasekuqaleni. Lokhu kuwumsebenzi onekhono, kodwa kuvumela ipuleti elonakele ukuthi libuyiselwe ekuphileni, empeleni liphinde lisethe impilo yalo yokusebenza. Ngokuphambene nalokho, yize i-granite ingavuselelwa, inqubo ihlukile futhi ivame ukudinga imishini ekhethekile ukuze iphinde ixhume itshe. Kubasebenzisi abaningi bezimboni, ikhono lokumane likhuhlwe ipuleti libuyele esitezi endlini noma endaweni liyinzuzo enkulu yezokuthutha.

Izindleko nazo ziyisici esibalulekile. Ngokuvamile, amapuleti ensimbi acwebezelayo ashibhile ukuwakhiqiza kune-granite efanayo nawo, ikakhulukazi ngobukhulu obukhulu kakhulu. Nakuba amabhulokhi amakhulu e-granite etholakala, izindleko zokuthola nokulungisa amatshe amakhulu, angenasici zingaba zinkulu kakhulu. Insimbi ecwebezelayo ingafakwa ezimeni ezinkulu neziyinkimbinkimbi, kufaka phakathi lezo ezine-T-slots, ezibalulekile ekubambeni izinto zokusebenza ezinkulu. Lokhu kuguquguquka kwenza insimbi ecwebezelayo ibe yisinqumo esithandwayo sokuhlanganiswa nokufakwa kwe-welding, lapho ipuleti lisebenza njengebhentshi lomsebenzi kanye nethuluzi lokulinganisa.

Uma unquma phakathi kwe-granite nensimbi ephonswe elebhu yakho ye-metrology, kufanele ubheke ngale kwezinto ngokwazo bese ucabangela ukusetshenziswa kwazo. Uma ukukhathazeka kwakho okuyinhloko kuwukunemba okuphezulu kakhulu—njengaselabhorethri yokulinganisa, igumbi le-CMM, noma isikhungo sokuhlola okubonakalayo—i-granite cishe iyona ndlela engcono kakhulu. Ukumelana kwayo nokushintsha kwezinga lokushisa, ukuntuleka kokuphazamiseka kwamagnetic, kanye nezidingo zokunakekelwa okuphansi kudala indawo ezinzile yezinsimbi ezibucayi. Iqiniso lokuthi ayigqwali lisho ukuthi ungasebenza endaweni ehlanzekile yegumbi ngaphandle kokukhathazeka ngenkungu kawoyela noma izinhlayiya zokugqwala ezingcolisa imikhiqizo yakho.

Kodwa-ke, uma "ilebhu" yakho empeleni iyindawo yokuhlola esezingeni eliphansi ngaphakathi kwesitolo semishini, noma uma uhlola izinto ezisindayo neziqinile, insimbi ephonswe ingaba yisisombululo esisebenzayo. Ingozi yokuphonsa ingxenye yensimbi esindayo epuletini le-granite iyisibopho abaphathi bezitolo abaningi abakhetha ukusigwema. Ukuqina kwensimbi, kuhlanganiswe nezindleko zayo zokuqala eziphansi kanye nekhono lokuyilungisa ngokuyiklwebha, kuyenza ibe yimpahla eqinile endaweni enzima. Ngaphezu kwalokho, uma inqubo yakho yokuhlola ihilela izingxenye eziningi ezisindayo ezishelelayo noma idinga ukusetshenziswa kwama-clamps kanye nezinto zokulungisa, isimo sokuzigcoba sobuso bensimbi eklwebhayo kanye nokutholakala kwama-T-slots kunikeza izinzuzo ezisebenzayo amatshe angenakuzifanisa.

Kubalulekile futhi ukuqaphela indlela "ye-hybrid". Izikhungo eziningi ezithuthukile zisebenzisa zombili. Zingasebenzisa itafula elikhulu lensimbi ephonswe ekuqaleni kanye nokulungiswa okuqinile kwezingxenye ezisindayo, bese zithutha ingxenye ziye epuletini le-granite elizinikele ukuze kulinganiswe okokugcina, okunembile kakhulu. Lo msebenzi wokusebenza ukhulisa amandla azo zombili izinto: ukuqina kwensimbi emsebenzini oqinile, kanye nokuqina kwe-granite emsebenzini omuhle.

Ekugcineni, impikiswano ethi “Granite vs. Cast Iron” ayimayelana nokuthi iyiphi into engcono ngokweqiniso, kodwa ukuthi iyiphi engcono kakhuluwena. I-Granite inikeza isiqongo sokuqina, ukunemba, kanye nokulula kokugcinwa, okwenza kube yiqhawe elingenakuphikiswa lelebhu yesimanje, elawulwa yisimo sezulu. Insimbi ephothiwe inikeza ukuqina, ukuguquguquka, kanye nokusebenza kahle kwezindleko, iqinisekisa indawo yayo njengomgogodla oqinile wokuhlolwa kwezimboni. Ngokuhlola ngokucophelela izimo zakho zemvelo, uhlobo lwezingxenye ozihlolayo, kanye namakhono akho okugcina isikhathi eside, ungakhetha ipuleti elingaphezulu elizosebenza njengesisekelo esithembeke kakhulu sohlelo lwakho lokuqinisekisa ikhwalithi. Kungakhathaliseki ukuthi ukhetha ukuzinza kwemvelo kwetshe noma ukuqina okuqinile kwensimbi, isihluthulelo sisekuqondeni i-physics ngemuva kwezinto ezibonakalayo nokuhlonipha imikhawulo yazo.
