Kwihlabathi elinobunzima obukhulu be-metrology, ibhloko ye-gage—edla ngokubizwa ngokuba yi-"Jo Block" emva komqambi wayo uCarl Edvard Johansson—yeyona mgwebi wenyaniso. Ezi rectangles zomhlaba ochanekileyo zisebenza njengemigangatho ephambili yokulinganisa umgca kwiivenkile zoomatshini nakwiilabhoratri zokulinganisa kwihlabathi liphela. Kangangamashumi eminyaka, intsimbi yezixhobo eziphezulu yayiyeyona nto ikhethwayo kwezi zixhobo zibalulekileyo. Nangona kunjalo, njengoko ukunyamezelana kokuvelisa kuye kwaqina kwaye imfuno yokuphila ixesha elide kwiindawo zeevenkile ezinzima ikhulile, kuye kwavela umlandeli obalaseleyo: iCeramic esekelwe kwiZirconia.
Nangona iibhloko zentsimbi ezisetyenziswa kwi-gage ziseyinto eqhelekileyo ngenxa yexabiso lazo eliphantsi lokuqala, ukutshintshela kwi-ceramic akusiyonto nje ithandwayo—yimpendulo kwimida yesinyithi. Kwibali elilandelayo, siza kuhlola ukuba kutheni iibhloko ze-gage ze-ceramic ziye zaba ngumgangatho wegolide kubavelisi abaqaphela umgangatho kunye nendlela abazisombulula ngayo iintloko ezingapheliyo ze-metrology yendabuko.
Ukungakhuseleki kwizinto ezibangela ukonakala: Ukuphela kokubola
Eyona nzuzo ikhawulezileyo necacileyo yokutshintshela kwi-ceramic kukungakhuseleki kwayo ngokupheleleyo ekugqwaleni. Intsimbi, nokuba ikumgangatho ophezulu kangakanani na, iyinto yentsimbi. Kwindawo yokuvelisa exakekileyo, ukufuma, inkungu yokupholisa, kwaneeoyile zendalo ezivela kwiminwe yengcali zinokubangela i-oxidation. Iminwe enye eshiywe kwibhloko yentsimbi ubusuku bonke inokubangela ukugqwala okungapheliyo, kutshabalalisa ukugqitywa okufana nesipili okufunekayo "ekubhideni" - inkqubo apho iibhloko ezimbini zityibilikiswana ndawonye ukuze ziqine.
Iibhloko ze-ceramic gage zahlukile ngokupheleleyo. Ekubeni zingabi nakhemikhali, azigqwali, azingcolisi, okanye zibole. Oku kususa isidingo semisebenzi yokulungisa edinisayo neyingxubakaxaka enxulumene nentsimbi, njengokufaka igrisi yokukhusela okanye iioyile zokulwa nomhlwa ngaphambi kokugcinwa. Kwigumbi lokuhlola elinomthamo omkhulu, ixesha eligcinwe ekucoceni nasekulungiseleleni iibhloko liguqulela ngokuthe ngqo ekuphuhlisweni okukhulu. Okubaluleke ngakumbi, kunika uxolo lwengqondo: akufuneki ukhathazeke ukuba ibhloko elilibeleyo ngasemva kwedrowa libe yinto engenamsebenzi yesinyithi esigqwalisiweyo.
Ukumelana nokunxitywa okuphezulu kunye nobude bexesha elide
Kwimveliso echanekileyo, ibhloko yegeji ilingana nobukhulu bayo kuphela. Ngalo lonke ixesha ibhloko icinezelwa kwenye okanye isetyenziselwa ukulinganisa i-micrometer, ubungakanani bezinto ezincinci ziyaphela. Iibhloko zentsimbi zithambile xa zithelekiswa nezinto ezihlala zilinganisa, nto leyo ekhokelela ekulahlekelweni kokuchaneka kancinci kancinci kwiminyaka emininzi yokusetyenziswa.
Iibhloko zeseramikhi, ingakumbi ezo zenziwe ngeZirconia yobuchwephesha obuphezulu, ziqinile kakhulu kunentsimbi. Zinokumelana nokuguguleka okuhlala kukhankanywa njengobukhulu obuphindwe kalishumi kuneebhloko zesinyithi zemveli. Obu bunzima buqinisekisa ukuba imiphezulu ethe tyaba, ehambelanayo yebhloko ihlala ngaphakathi kokunyamezelana kwayo okuchaziweyo ixesha elide kakhulu. Kwiinkampani ezenza uhlolo lwe-ISO rhoqo, oku kuthetha ukuba ii-calibration ezimbalwa ezisileleyo kunye nokutshintshwa okuphantsi, okwenza utyalo-mali lokuqala oluphezulu kwiseramikhi lube lukhetho olunoqoqosho ngakumbi kumjikelo wobomi bemveliso iyonke.
Ingxaki nge "Burrs" kunye ne-Surface Integrity
Enye yeengozi "ezifihlakeleyo" zeebhloko zentsimbi yi-burr. Xa ibhloko yentsimbi iwiswe ngengozi okanye ibethwa kwindawo eqinileyo, isinyithi siyasuswa, sidla ngokudala umphetho ophakanyisiweyo okanye "i-crater." Ukuba ingcali ayiqapheli le burr kwaye izama ukujija ibhloko kwenye, isinyithi esiphakanyisiweyo sinokukrwela umphezulu webhloko yesibini, nto leyo ebangela umonakalo omkhulu kuyo yonke iseti ebiza kakhulu.
I-ceramic iziphatha ngendlela eyahlukileyo. Ngenxa yokuba ithambile kodwa iqinile ngendlela emangalisayo, i-ceramic ayisebenzisi "ikhowa" okanye idale i-burr xa ibetha. Ukuba ibhloko ye-ceramic iwile, iya kuhlala injalo okanye, kwiimeko ezigqithisileyo, iqhekeza elincinci linokuqhekeka. Okubaluleke kakhulu, umphezulu oseleyo uhlala uthe tyaba ngokugqibeleleyo. Ayizuku "vuthuluka" phezulu, oko kuthetha ukuba ayisoze yonakalise ezinye iibhloko ngengozi okanye inike umfanekiso ongeyonyani, omkhulu ngexesha lokuhlolwa.
Uzinzo kunye noLawulo lweThermal
Ukulinganisa ngokuchanekileyo kukudanisa nobushushu. Uninzi lokulinganisa kwemizi-mveliso luqhelekile ukuya kuma-20℃ (68℉), kodwa ubushushu obuvela esandleni somntu bunokubangela ukuba ibhloko yegeyiji yande kakhulu. Izinto zeseramikhi zine-coefficient yokwandiswa kobushushu ehlala iphantsi kwaye iqikeleleka ngakumbi kwiindawo ezithile xa kuthelekiswa nentsimbi.
Nangona ukwanda kobushushu be-ceramic kudla ngokusondela ngokwaneleyo kwintsimbi ukuvumela ukuthelekiswa ngokuthe ngqo neenxalenye zentsimbi, ukuhanjiswa kobushushu obuphantsi kwezinto ze-ceramic yeyona nzuzo inkulu. I-ceramic ayifunxi ubushushu esandleni ngokukhawuleza njengentsimbi. Oku kuthetha ukuba ingcali inokuphatha ibhloko ye-ceramic ixesha elide ngaphandle kokubangela "ukukhula" okukhawulezayo okwenzeka ngesinyithi, okukhokelela ekulinganisweni okuzinzileyo nokuphindaphindiweyo ngexesha leenkqubo zokuhlolwa ngesandla.
Iimpawu ezingezizo zeMagnetic nezingezizo zeConductive
Kwimveliso yanamhlanje, ngakumbi kumashishini e-semiconductor kunye ne-elektroniki, i-magnetism yinto ehlala ixhalabisa. Iibhloko ze-steel gage zinokuba ne-magnetization ngokuhamba kwexesha, ngakumbi ukuba zisetyenziswa kufutshane nee-magnetic chucks okanye izixhobo ze-high-voltage. Ibhloko ene-magnetization itsala uthuli lwesinyithi oluncinci kunye ne-swarf, enokusebenza njengento erhabaxa kwaye yonakalise umphezulu ojikelezayo okanye ikrwele indawo elinganiswayo.
I-ceramic ayisebenzi ngemagnethi ngokupheleleyo. Ayisoze itsale iifayili zesinyithi, iqinisekisa ukuba unxibelelwano phakathi kwegeji kunye nenxalenye luhlala lucocekile. Ngaphezu koko, njenge-insulator yombane, iibhloko ze-ceramic zilungele ukusetyenziswa apho ukuhanjiswa kombane kunokuphazamisana nezinto ze-elektroniki ezinobuthathaka okanye ii-sensors.
Isiphelo: Kutheni iSwitch Isenza Ingqiqo
Utshintsho ukusuka kwintsimbi ukuya kwiibhloko ze-ceramic gage lubonisa intshukumo eya ekuchanekeni "okungenakulungiswa". Ngokususa iingozi zokugqwala, i-magnetism, kunye nokugqabhuka, i-ceramic ivumela amasebe olawulo lomgangatho ukuba agxile kwizinto ezibaluleke kakhulu: ukuchaneka. Ngelixa ixabiso lokuqala leseti ye-ceramic liphezulu, indibaniselwano yokuqina okugqithisileyo, imijikelo yokulinganisa encitshisiweyo, kunye nokususwa kweengubo zokukhusela kuzenza zibe sisisombululo esingabizi kakhulu kuyo nayiphi na indawo echanekileyo.
Nokuba ulinganisa izinto zeenqwelo moya nge-sub-micron tolerances okanye ukhangela nje umgangatho othembekileyo ngakumbi kwivenkile yakho yoomatshini, iibhloko ze-ceramic gage zibonelela ngesiseko sozinzo esingenakufaniswa nentsimbi.
