Iibhloko zegauge (ezidla ngokubizwa ngokuba ziibhloko zeJo) zisebenza njengomgangatho ophambili we-physical we-dimensional metrology kwihlabathi liphela. Ukulinganiswa kwe-micrometer nganye, i-height gauge zeroing, kunyeumatshini wokulinganisa olungelelanisiweyoUhlolo lwe-axis (CMM) lulandelela umgca walo wobukhulu ubuyela kwinqwaba yeebhloko ze-gauge ezingqinisisiweyo nge-laser interferometers.
Ukukhetha izinto ezingalunganga okanye udidi lokuchaneka kuzisa iimpazamo ezincinci zobushushu, ukusilela kokusonta, kunye nokuguguleka okungeyomfuneko. Iseti yokulinganisa yeBanga K eyenzelwe ilebhu yokulawula okusingqongileyo iya konakala ngokukhawuleza ukuba ibekwe kumgangatho wevenkile onamafutha, ngelixa iseti yentsimbi engabizi kakhulu esetyenziselwa ukuseta uthelekiso oluchanekileyo kakhulu izisa ukungaqiniseki okungamkelekanga.
Ukuqonda amanqanaba okuchaneka, ifiziksi yezinto eziphathekayo, kunye ne-wringing dynamics kuqinisekisa ukuba useto lwakho lomgangatho lugcina uthotho olungapheliyo lokulandeleka kwemetrological.
1. Ukukhetha iBanga lokuChaneka eliLungileyo (ISO 3650 / ASME B89.1.9)
Imigangatho yamazwe ngamazwe yahlulahlula iibhloko zeegeyiji zibe ziiklasi ezine eziphambili ngokusekelwe ekuphambukeni kobude kunye nokunyamezelana kokutyibilika:
+-------------------+- ...Ibanga K (Ibanga loLungiso)
Iibhloko zeBanga le-K zithwala ubude obuqinileyo kunye nokunyamezelana okufana, kodwa azisetyenziselwa ukulinganisa imihla ngemihla. Umsebenzi wazo kuphela kukulinganisa iibhloko zokulinganisa ezisebenzayo (iBanga le-0 okanye le-1). Iilabhoratri ezisebenzisa iiseti zeBanga le-K zifuna ii-interferometers eziphezulu okanye ii-mechanical comparators ukuze zibambe utshintsho lwe-micro-intshi.
Ibanga 0 kunye neBanga 1
Ibanga 0 lisebenza njengomgangatho osebenzayo ngaphakathi kwamagumbi okuhlola alawulwa yimozulu ukuze kulinganiswe ii-micrometer, iiringi zokuseta, kunye neeprobe ze-elektroniki. Iibhloko zebanga 1 zijongana nokuhlolwa ngokuchanekileyo ngokubanzi kumgangatho wevenkile apho ukuguquguquka kobushushu kuhlala ngaphakathi kwemida ephakathi.
2. Ukukhetha Izinto: Intsimbi vs. Ikhabhayithi vs. Iseramikhi
Ukukhetha izinto ezifanelekileyo kufuna ukulinganisela ukuhambelana kobushushu, ukumelana nokuguguleka, kunye nokumelana nokugqwala.
+------------------------------+---------------------------------+-----------------------------+---------------------------+ | Ipropati yezinto eziphathekayo | Intsimbi (i-alloy) | I-Tungsten Carbide | I-Ceramic (i-Zirconia) | +- ... +- ...+-----------------------Intsimbi
Intsimbi iselukhetho lwendabuko nolungabizi kakhulu. Umlinganiselo wayo wokwandiswa kobushushu uhambelana kakhulu neenxalenye zoomatshini bentsimbi abaqhelekileyo, nto leyo enciphisa iimpazamo zokwandiswa komahluko ngexesha lokuhlolwa komgangatho wevenkile. Nangona kunjalo, intsimbi ifuna ioyile rhoqo ukuthintela ukugqwala kunye nokukrweleka ngokulula xa ivezwa kumdaka.
I-Tungsten Carbide
I-Carbide inika ukumelana nokuguguleka okuphindwe kalishumi kunentsimbi yesixhobo. Uxinano lwayo oluphezulu kunye nokumelana nokukrwela kwenza ukuba ilungele izikhululo zokuhlola ezinomthamo ophezulu. Nangona kunjalo, i-coefficient yayo yokwandisa ubushushu obuphantsi (~ 4.5 × 10⁻⁶/C) ifuna izinto zokulungisa ubushushu ngononophelo xa ilinganisa izinto zentsimbi kumaqondo obushushu akude ne-20℃.
I-Zirconia Ceramic
I-Zirconia ceramic iye yaba yinto ekhethwayo kwiilabhoratri ezisemgangathweni zanamhlanje. Iibhloko ze-ceramic azinawo umhlwa ngokupheleleyo, azinamagnethi, kwaye azingenwa zii-micro-burr. Ukuwisa ibhloko ye-ceramic akuyi kuphakamisa i-edge burr; isuka nje iqhekezeke kakuhle ngaphandle kokuphazamisa iiplani ezisicaba ezijikelezileyo. Ngaphezu koko, izinga layo lokukhula kobushushu (~ 9.8 × 10⁻⁶/C) lihambelana ngokusondeleyo nentsimbi, okwenza kube lula ukubala imbuyekezo yobushushu.
3. Imbonakalo yokusonta kunye nomgangatho womphezulu
Ukusonta—inkqubo yokutyibiliza iibhloko ezimbini ezicocekileyo nezithe tyaba kunye phantsi koxinzelelo oluncinci ukuze zinamathele ngaphandle kwezinto zokubopha zangaphandle—kuxhomekeke ekunxibelelaneni kweemolekyuli ezithe tyaba kakhulu kunye nokutsala kweemolekyuli kwiifilimu zolwelo ezincinci.
INDLELA YOKUQHUMA Ibhloko A (Phezulu) [===============================]=" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ <-- Ifilimu yeoyile ebhityileyo kakhulu (isikali se-nanometer) Ibhloko B (Ezantsi) [=================================]=" --> Ukutsalana kweemolekyuli + uxinzelelo lomoya zibamba iibhloko ndawonye ngokuqinileyo.Ukusonga ngempumelelo kufuna i-topography yomphezulu ecocekileyo. Ukuba isiseko sebhloko yokulinganisa okanye ubuso bokulinganisa bunee-scratch burrs, uthuli oluphuma emoyeni, okanye i-oyile film buildup, umsantsa wokusonga uyanda ngama-nanometer aliqela, nto leyo eyenza ukuba ukulinganisa kwe-Grade 0 kungasebenzi.
Kwiziko lethu lemveliso laseJinan, ukugcina ukuchaneka kokulinganisa imigangatho yokulinganisa yangaphakathi kuxhomekeke ekudibaniseni iibhloko ze-ceramic kunye ne-steel gauge kunye neeplate ze-granite ezimnyama ze-ZHHIMG® (≈ 3100 kg/m³). Ngenxa yokuba i-granite enoxinano oluphezulu inika isiseko esingangenisi magnethi, esingenamagnethi, esinamalephu amancinci ngaphakathi kweeworkshop zethu ezingama-10,000 m² zobushushu obungaguqukiyo, iingcali zinokusonga kwaye ziqinisekise iibhloko ngaphandle kokuphazamiseka kokungcangcazela komhlaba okutshintsha ubude bokufundwa.
4. Ukulandelelana koLungiso kunye noLawulo lokusingqongileyo
Ukuthenga iibhloko ezikumgangatho ophezulu akuthethi nto ingako ukuba indawo yakho yokulinganisa ayinazo uzinzo lwendalo kunye nokulandeleka kwemetrological.
-
Ukufunxa ubushushu: Ngaphambi kokuba ulinganise okanye ugobe, vumela iibhloko kunye nezinto zokusebenza ukuba zifunxe kwilebhu elawulwa yimozulu (20 ℃) ubuncinane iiyure ezi-2 ukuya kwezi-4. Iibhloko zokuphatha ngokuthe ngqo ngezandla ezinganxibanga zidlulisela ubushushu bomzimba ngoko nangoko, zandise ibhloko ye-100 mm nge-micron epheleleyo kwimizuzwana embalwa. Soloko usebenzisa iitongs ezigqunyiweyo okanye iiglavu zekotoni.
-
Ukulandelelwa kweLabhoratri yeSizwe: Qinisekisa ukuba izatifikethi zokulinganisa zivela kwizibonelelo ezivunyiweyo ezinokulandelelwa zibuyela kumaziko emetrology kazwelonke (i-NIM, i-PTB, i-NPL, okanye i-NIST). Yonke imigangatho yezixhobo ezisetyenziswa kwi-ZHHIMG inokuqinisekiswa kokulinganisa okukhutshwe ngamaziko emetrology ephondo nawesizwe avunyiweyo.
-
Iindlela zokucoca: Coca iibhloko ngaphambi nasemva kokusebenzisa usebenzisa ii-optical-grade anhydrous alcohol kunye nee-lint-free wipes. Iiseti zentsimbi kufuneka zigqunywe kancinci nge-asidi-free petrolatum ngaphambi kokuba zigcinwe.
Uluhlu lokuHlola oluSebenzayo lweeNjineli zoMgangatho
Xa ukhetha iibhloko zokulinganisa zesixhobo sakho:
-
Tshatisa izinto zebhloko nezinto zakho zokusebenza: Khetha i-ceramic yokujonga intsimbi ngokubanzi kunye nokusetyenziswa kwegumbi lokucoca; khetha i-carbide yokusebenzela esetyenziswa kakhulu.
-
Gcina iibhloko zeBakala K kunye neBakala 0 ziqinile ngaphakathi kwamagumbi okulinganisa alawulwa yimozulu (20°C ± 0.5°C).
-
Ungaze ugcine iibhloko ezixovulwe ubusuku bonke. Ukutshiza okubandayo kunye nokufuma komoya kuya kuzidibanisa ubuso obudibeneyo ngonaphakade.
-
Qinisekisa ukuba ipleyiti yakho yomphezulu wereferensi ithambile (DIN 876 Grade 00) ngaphambi kokuba usete izitendi zokuthelekisa ukuze uphephe iimpazamo zokuphambuka kwesiseko.
Ngokufanisa umgangatho, izinto, kunye nemigaqo yokuphatha kwindawo yakho yokulinganisa ethile, ilebhu yakho igcina isiseko esingapheliyo sesalathiso sayo yonke imveliso ephuma kwifektri yakho.
