Kwinjineli ye-ultra-precision, i-granite icandelo lelona qela libonisa ireferensi, libonelela ngesiseko sozinzo lwezixhobo ezisebenza kwi-micro kunye ne-nanometer scales. Nangona kunjalo, nezona zinto zizinzile ngokwendalo-yethu i-ZHHIMG® high-density black granite-inokuhambisa amandla ayo apheleleyo ukuba inkqubo yokulinganisa ngokwayo ilawulwa ngokungqongqo kwezesayensi.
Iinjineli kunye nee-metrologists ziqinisekisa njani ukuba iziphumo zomlinganiso zichanekile ngokwenene? Ukufezekisa iziphumo ezichanekileyo, eziphindaphindiweyo ngexesha lokuhlolwa kunye nokuqinisekiswa kokugqibela kweziseko zomatshini wegranite, iibheringi zomoya, okanye izakhiwo zeCMM zifuna ingqalelo engqongqo kwiinkcukacha ngaphambi kokuba isixhobo sokulinganisa sichukumise umphezulu. Olu lungiselelo luhlala lubaluleke kakhulu njengesixhobo sokulinganisa ngokwaso, siqinisekisa ukuba iziphumo zibonisa ngokunyanisekileyo ijometri yecandelo, hayi izinto zakudala zokusingqongileyo.
1. Indima enguNdoqo yoBume be-Thermal (Ixesha lokuPhuma)
I-Granite ine-Coefficient ephantsi kakhulu ye-Thermal Expansion (COE), ngakumbi xa kuthelekiswa neentsimbi. Nangona kunjalo, nayiphi na imathiriyeli, kubandakanywa negranite yoxinaniso oluphezulu, kufuneka izinziswe ngokushushu emoyeni nakwisixhobo sokulinganisa phambi kokuba uqinisekiso luqale. Oku kwaziwa njengexesha lokuphuma kwamanzi.
Inxalenye enkulu yegranite, ingakumbi leyo isandula kufuduswa ukusuka kumzi-mveliso ukuya kwilebhu ye-metrology ezinikeleyo, iya kuthwala i-thermal gradients-umahluko kubushushu phakathi kombindi wayo, umphezulu kunye nesiseko. Ukuba umlinganiselo uqala kwangethuba, igranite iya kwanda ngokucothayo okanye ikhonkotha njengoko ilingana, nto leyo ekhokelela ekuqhubeni kokufunda.
- Umgaqo weThupha: Amacandelo achanekileyo kufuneka ahlale kwindawo yokulinganisa-iqondo lethu lobushushu kunye namagumbi okucoca alawulwa ngumswakama-ixesha elide, rhoqo kwiiyure ezingama-24 ukuya kwii-72, kuxhomekeke kubunzima becandelo kunye nobukhulu. Injongo kukuphumeza ukulingana kwe-thermal, ukuqinisekisa icandelo legranite, isixhobo sokulinganisa (esifana ne-laser interferometer okanye inqanaba lombane), kunye nomoya zonke zikwiqondo lobushushu elivunyiweyo lamazwe ngamazwe (elidla ngokuba yi-20℃).
2. Ukukhetha umphezulu kunye nokucocwa: Ukuphelisa utshaba lokuchaneka
Ukungcola, uthuli, kunye nobutyobo zezona ntshaba zinkulu zomlinganiselo ochanekileyo. Nokuba incinci encinci ye-microscopic yothuli okanye i-fingerprint eshiyekileyo inokudala ukuphakama kokuma okubonisa ngobuxoki impazamo yee-micrometer ezininzi, ukuphazamisa kakhulu umlinganiselo wokutya okanye ukuthe tye.
Phambi kokuba naluphi na uphando, isibonisi, okanye isixhobo sokulinganisa sibekwe kumphezulu:
- Ukucocwa ngokucokisekileyo: Umphezulu wecandelo, nokuba yinqwelo-moya yesalathiso okanye i-pad yokukhwela kumzila kaloliwe onqamlezileyo, kufuneka icocwe ngokucokisekileyo kusetyenziswa isicoci esifanelekileyo, esingena-lint kunye ne-agent ecocekileyo yokucoca (ngokuqhelekileyo utywala bemizi-mveliso okanye isicoci esizinikezeleyo segranite).
- Sula phantsi iZixhobo: Okubaluleke ngokufanayo kukucocwa kwezixhobo zokulinganisa ngokwazo. Iireflector, iziseko zezixhobo, kunye neengcebiso zophando kufuneka zingabinachaphaza ukuqinisekisa unxibelelwano olugqibeleleyo kunye nendlela yokwenyani yokubona.
3. Ukuqonda iNkxaso kunye nokukhululwa koxinzelelo
Indlela inxalenye yegranite exhaswa ngayo ngexesha lokulinganisa ibalulekile. Izakhiwo ezinkulu, ezinzima zegranite ziyilelwe ukugcina ijometri yazo xa zixhaswa kwiindawo ezithile, ezibalwe ngokwemathematika (kaninzi zisekelwe kwiindawo ze-Airy okanye ze-Bessel ukwenzela ukuba flatness efanelekileyo).
- UkuFaka okuLungileyo: Ukuqinisekiswa kufuneka kwenzeke kunye nenxalenye yegranite ephumle kwizixhaso ezichongwe yiplani yobunjineli. Amanqaku okuxhasa angalunganga anokubangela uxinzelelo lwangaphakathi kunye nokuphambuka kwesakhiwo, ukuphazamisa umphezulu kunye nokubonelela ngokungachanekanga "ngaphandle kokunyamezela" ukufunda, nokuba icandelo lenziwe ngokugqibeleleyo.
- Ukwahlulwa kweVibration: Indawo yokulinganisa kufuneka yona ngokwayo ibe yodwa. Isiseko se-ZHHIMG, esinomgangatho wekhonkrithi ochasene nokungcangcazela kwemitha enye nobunzulu kunye nomsele wokwahlukanisa ubunzulu obungama-2000 mm, unciphisa uphazamiseko lwangaphandle lwenyikima kunye noomatshini, ukuqinisekisa ukuba umlinganiselo uthathwa kumzimba ongatshintshiyo ngokwenene.
4. Ukhetho: Ukukhetha iSixhobo seMetrology esiLungileyo
Ekugqibeleni, isixhobo esifanelekileyo sokulinganisa kufuneka sikhethwe ngokusekelwe kwibakala elichanekileyo elifunekayo kunye nejometri yecandelo. Akukho sixhobo esinye sigqibeleleyo kuwo wonke umsebenzi.
- I-Flatness: Kwi-flatness ephezulu echanekileyo kunye nefomu yejometri, i-Laser Interferometer okanye i-Autocollimator enesisombululo esiphezulu (ehlala idityaniswe neNqanaba loMbane) inika isisombululo esiyimfuneko kunye nokuchaneka kwexesha elide.
- Ukuchaneka kweNgingqi: Ukukhangela ukunxiba kwendawo okanye ukuphindaphinda (Ukuphindaphinda ukuchaneka kokuFunda), amaNqanaba e-elektroniki achanekileyo okanye i-LVDT / i-Capacitance Probes enezigqibo ukuya kwi-0.1 μm ziyimfuneko.
Ngokuthobela ngokucokisekileyo kula manyathelo okulungiselela-ukulawula ukuzinza kwe-thermal, ukugcina ukucoceka, kunye nokuqinisekisa inkxaso echanekileyo yesakhiwo-iqela lobunjineli be-ZHHIMG liqinisekisa ukuba imilinganiselo yokugqibela yamacandelo ethu achanekileyo yimbonakaliso eyinyani kwaye ethembekileyo yokuchaneka komgangatho wehlabathi ohanjiswe ngezinto zethu kunye neenkosi zethu zezandla.
