Ezweni elibaluleke kakhulu le-metrology, i-gage block—evame ukubizwa ngokuthi “i-Jo Block” ngemuva komsunguli wayo uCarl Edvard Johansson—iyi-arbiter ephelele yeqiniso. Lawa ma-rectangles aphansi anembile asebenza njengezindinganiso eziyinhloko zokulinganisa okuqondile ezitolo zemishini nasema-lab okulinganisa emhlabeni jikelele. Sekungamashumi eminyaka, insimbi yamathuluzi esezingeni eliphezulu yayiyizinto ezikhethwayo ezingaphikiswana ngazo kula mathuluzi abalulekile. Kodwa-ke, njengoba ukubekezelelana kokukhiqiza kuye kwaqina futhi isidingo sokuphila isikhathi eside ezindaweni zezitolo ezinzima sikhulile, kuye kwavela umlandeli ongcono: i-Zirconia-based Ceramic.
Nakuba amabhlogo ensimbi ahlala eyinto ebalulekile ngenxa yezindleko zawo zokuqala eziphansi, ukushintshela ku-ceramic akuyona nje into eyenzeka—kuyimpendulo yokulinganiselwa okungokwenyama kwensimbi. Endabeni elandelayo, sizohlola ukuthi kungani amabhlogo e-ceramic asebe yindinganiso yegolide yabakhiqizi abaqaphela ikhwalithi nokuthi baxazulula kanjani izinkinga eziqhubekayo ze-metrology yendabuko.
Ukungavikeleki Ezintweni Eziphilayo: Ukuphela Kokugqwala
Inzuzo eshesha kakhulu nesobala yokushintshela ku-ceramic ukuzivikela kwayo ngokuphelele ekugqwaleni. Insimbi, kungakhathaliseki ukuthi ikhwalithi yayo iphakeme kangakanani, iyinto ensimbi. Esikhungweni sokukhiqiza esimatasa, umswakama, inkungu yokupholisa, ngisho namafutha emvelo avela ezandleni zochwepheshe kungabangela ukubola. Umunwe owodwa oshiywe ebhulokini lensimbi ubusuku bonke ungabangela ukugqwala okuhlala njalo, konakalisa ukuphela okufana nesibuko okudingekayo "ekusonteni" - inqubo lapho amabhulokhi amabili ehlanganiswa ndawonye ukuze aqine.
Amabhlogo e-ceramic gage ahluke kakhulu. Njengoba engagqwali ngamakhemikhali, awagqwali, awangcoli, noma agqwale. Lokhu kuqeda isidingo semisebenzi yokulungisa ekhathazayo neyingcolile ehlobene nensimbi, njengokufaka amafutha okuvikela noma amafutha okulwa nokugqwala ngaphambi kokugcina. Egumbini lokuhlola elinomthamo omkhulu, isikhathi esilondolozwa ekuhlanzeni nasekulungiseleleni amabhlogo sihunyushwa ngqo ekukhuleni komthamo. Okubaluleke kakhulu, kunikeza ukuthula kwengqondo: awusoze wakhathazeka ngokuthi ibhloko elikhohliwe ngemuva kwedrowa seliphenduke ingxenye yensimbi egqwalile engenamsebenzi.
Ukumelana Nokugqoka Okuphezulu Nokuphila Isikhathi Eside
Ekukhiqizeni ngokunemba, ibhlogo le-gage lilingana nosayizi walo kuphela. Njalo lapho ibhloko licindezelwa kwelinye noma lisetshenziselwa ukulinganisa i-micrometer, inani elincane lezinto liyaguga. Amabhlogo ensimbi athambile uma kuqhathaniswa nezinto avame ukuzilinganisa, okuholela ekulahlekelweni kancane kancane kokunemba eminyakeni eminingi yokusetshenziswa.
Amabhulokhi e-ceramic, ikakhulukazi lawo enziwe nge-Zirconia yobuchwepheshe obuphezulu, aqinile kakhulu kunensimbi. Anamandla okuguguleka avame ukubizwa ngokuthi makhulu ngokuphindwe kayishumi kunamabhulokhi ensimbi yendabuko. Lobu bunzima buqinisekisa ukuthi izindawo ezisicaba, ezifanayo zebhulokhi zihlala ngaphakathi kokubekezelela kwazo okucacisiwe isikhathi eside kakhulu. Ezinkampanini ezihlola njalo i-ISO, lokhu kusho ukulinganiswa okumbalwa okuhlulekile kanye nemvamisa ephansi yokushintshwa, okwenza ukutshalwa kwezimali kokuqala okuphezulu ku-ceramic kube ukukhetha okungabizi kakhulu kunomjikelezo wokuphila womkhiqizo.
Inkinga "ngama-Burrs" kanye nobuqotho bomphezulu
Enye yezingozi “ezifihliwe” zamabhulokhi ensimbi avikelayo yi-burr. Uma ibhulokhi yensimbi iwiswa ngengozi noma ishaywa endaweni eqinile, insimbi iyasuka, ivame ukudala unqenqema oluphakanyisiwe noma “i-crater.” Uma uchwepheshe engayiboni le burr futhi ezama ukusonta ibhulokhi kwenye, insimbi ephakanyisiwe ingaklwebha ubuso bebhulokhi yesibili, okubangela ukusabela kochungechunge lomonakalo kuyo yonke isethi ebizayo.
I-Ceramic iziphatha ngendlela ehlukile. Ngenxa yokuthi ithambile kodwa iqine kakhulu, i-ceramic ayikhi "ikhowe" noma idale i-burr uma ishayisana. Uma ibhlogo le-ceramic liwa, lizohlala liphelele noma, ezimweni ezimbi kakhulu, ingxenye encane ingase iqhekezeke. Okubaluleke kakhulu, indawo esele ihlala ithambe ngokuphelele. Ngeke "iqhume" phezulu, okusho ukuthi ngeke ilimaze amanye amabhlogo ngengozi noma inikeze ukufundwa okungamanga, okukhulu ngesikhathi sokuhlolwa.
Ukuzinza Nokuphathwa Kokushisa
Ukulinganisa ngokunemba kuyindlela yokulinganisa izinga lokushisa. Izilinganiso eziningi zezimboni zijwayelekile zibe ngu-20℃ (68℉), kodwa ukushisa okuvela esandleni somuntu kungabangela ukuthi i-gage block ikhule kakhulu. Izinto zobumba zine-coefficient yokwanda kokushisa okuvame ukuba phansi futhi okubikezelwa kalula ezindaweni ezithile uma kuqhathaniswa nensimbi.
Nakuba ukwanda kokushisa kwe-ceramic kuvame ukusondela ngokwanele ensimbini ukuvumela ukuqhathaniswa okuqondile nezingxenye zensimbi, ukuhanjiswa kokushisa okuphansi kwezinto kuyinzuzo enkulu. I-Ceramic ayimunci ukushisa esandleni ngokushesha njengensimbi. Lokhu kusho ukuthi uchwepheshe angaphatha ibhulokhi le-ceramic isikhathi eside ngaphandle kokubangela "ukukhula" okusheshayo okwenzeka ngensimbi, okuholela ekulinganisweni okuzinzile nokuphindaphindekayo ngesikhathi sezinqubo zokuhlola ngesandla.
Izakhiwo Ezingezona EzikaMagnetic Nezingahambisani Nokuqhutshwa Kwezinto
Ezimbonini zesimanje, ikakhulukazi embonini ye-semiconductor kanye ne-electronics, i-magnetism iyinkinga eqhubekayo. Amabhulokhi e-gage ensimbi angaba ne-magnet ngokuhamba kwesikhathi, ikakhulukazi uma esetshenziswa eduze kwama-chuck magnetic noma imishini enamandla kagesi. Ibhulokhi ene-magnet idonsela uthuli lwensimbi oluncane kanye ne-swarf, okungasebenza njengento ekhuhlayo futhi yonakalise indawo egoqayo noma iklwebhe ingxenye elinganiswayo.
I-Ceramic ayiyona nhlobo i-magnetic. Ngeke idonse amafayili ensimbi, okuqinisekisa ukuthi ukuxhumana phakathi kwe-gage nengxenye kuhlala kuhlanzekile. Ngaphezu kwalokho, njenge-insulator kagesi, amabhlogo e-ceramic afanele ukusetshenziswa lapho ugesi ungaphazamisa izingxenye noma izinzwa ze-elekthronikhi ezizwelayo.
Isiphetho: Kungani Ushintsho Lunengqondo
Ukushintsha kusuka ensimbini kuya kumabhulokhi e-ceramic gage kumelela ukuqhubekela phambili ekuqondeni "okungenakulungiswa". Ngokususa izingozi zokugqwala, amandla kazibuthe, kanye nokubhoboka, i-ceramic ivumela iminyango yokulawula ikhwalithi ukuthi igxile kulokho okubaluleke kakhulu: ukunemba. Ngenkathi iphuzu lentengo yokuqala yesethi ye-ceramic liphezulu, inhlanganisela yokuqina okukhulu, imijikelezo yokulinganisa encishisiwe, kanye nokususwa kwezimbozo zokuvikela kuzenza zibe yisisombululo esisebenza kahle kakhulu kunoma iyiphi indawo enembile kakhulu.
Kungakhathaliseki ukuthi ulinganisa izingxenye zezindiza nge-sub-micron tolerances noma umane ufuna indinganiso ethembeke kakhulu yesitolo sakho semishini, amabhlogo e-ceramic gage anikeza isisekelo sokuzinza insimbi engenakukwazi ukufanisa.
