Muuinjiniya hwekupedzisira-chaiyo, chikamu chegranite ndicho chekupedzisira chereferenzi, chinopa hwaro hwekugadzikana kwezviridzwa zvinoshanda pazvikero zvemicro uye nanometer. Nekudaro, kunyangwe iyo yakagadzika zvinhu zvakanyanya-yedu ZHHIMG® yakakwira-density dema granite-inogona chete kuendesa kugona kwayo kuzere kana kuyerwa kwacho kuchiitwa nekuomarara kwesainzi.
Mainjiniya nemametrologist vanoita sei kuti mhedzisiro yekuyera ndeyechokwadi? Kuwana chaiyo, inodzokororwa mhedzisiro panguva yekuongorora uye kwekupedzisira kuoneswa kwegranite mabhesi emuchina, mabhengi emhepo, kana CMM zvimiro zvinoda kunyatsotariswa kune zvakadzama chiridzwa chekuyeresa chisati chabata pamusoro. Kugadzirira uku kunowanzo kosha semidziyo yekuyeresa pachayo, kuve nechokwadi chekuti mhedzisiro inonyatsoratidza chikamu chejiometry, kwete zvezvakatipoteredza.
1. Basa Rakakosha reKupisa Kwekupisa (The Soak-Out Period)
Granite ine yakasarudzika yakaderera Coefficient yeThermal Expansion (COE), kunyanya ichienzaniswa nesimbi. Asi, chero chinhu, kusanganisira high-density granite, inofanira kudzikamiswa nemhepo kumhepo yakadzika uye mudziyo wekuyeresa kusati kwatanga. Iyi inozivikanwa senguva yekunyura.
Chikamu chikuru chegranite, kunyanya chichangobva kutama kubva pauriri hwefekitori kuenda kune yakatsaurirwa metrology lab, chinotakura kupisa kwemagetsi-kusiyana kwetembiricha pakati pepakati payo, pamusoro, uye chigadziko. Kana kuyerwa kukatanga nguva isati yakwana, giraniti inokura zvishoma nezvishoma kana chibvumirano sezvainoenzana, zvichiita kuti irambe ichidonha mukuverenga.
- Mutemo Wechigunwe: Zvakajeka zvinofanirwa kugara munzvimbo yekuyerwa - tembiricha yedu uye hunyoro-inodzorwa dzimba dzekuchenesa - kwenguva yakareba, kazhinji maawa makumi maviri nemana kusvika makumi manomwe nemaviri, zvichienderana nehuremu hwechikamu uye ukobvu. Chinangwa ndechekuwana kuenzana kwekupisa, kuve nechokwadi chechikamu chegranite, mudziyo wekuyeresa (senge laser interferometer kana chiyero chemagetsi), uye mhepo zvese zviri patembiricha inozivikanwa pasi rose (kazhinji 20 ℃).
2. Kusarudzwa Kwepamusoro uye Kuchenesa: Kubvisa Muvengi Wekururama
Tsvina, guruva, uye marara ndivo vavengi vakuru vechiyero chakarurama. Kunyange chidimbu cheguruva cheguruva kana chigunwe chakasara chinogona kugadzira kukwirira-kureba kunoratidza kukanganisa kwema micrometer akati wandei, zvichikanganisa zvakanyanya kuyerwa kwekudzika kana kutwasuka.
Pamberi pechero probe, reflector, kana yekuyeresa yaiswa pamusoro:
- Kunyatsocheneswa: Iyo chikamu chepamusoro, ingave iri ndege yereferensi kana pedhi yekumisikidza njanji ine mutsara, inofanirwa kucheneswa zvine hungwaru uchishandisa yakakodzera, isina-isina pukuta uye yakanyanya-kuchena yekuchenesa ajenti (kazhinji doro remumaindasitiri kana yakatsaurwa yegranite yekuchenesa).
- Pukuta pasi Zvishandiso: Zvakaenzana zvakakosha kucheneswa kwemidziyo yekuyeresa pachayo. Reflectors, mabhesi ezviridzwa, uye matipi ekuferefeta anofanirwa kunge asina gwapa kuti ave nechokwadi chekusangana uye yechokwadi yekuona nzira.
3. Kunzwisisa Rutsigiro uye Stress Release
Nzira iyo chikamu chegranite chinotsigirwa panguva yekuyera yakakosha. Zvimiro zvakakura, zvinorema zvegranite zvakagadzirirwa kuchengetedza geometry yavo kana ichitsigirwa pane chaiyo, masvomhu akaverengerwa mapoinzi (kazhinji akavakirwa paAiry kana Bessel mapoinzi ekunyatso flatness).
- Kukwira Kwazvo: Kusimbisa kunofanirwa kuitika nechikamu chegranite chakazorora pamatsigiro akasarudzwa neinjiniya blueprint. Mapoinzi ekutsigira asina kunaka anogona kukonzeresa kushushikana kwemukati uye kutsauka kwechimiro, kuchinjika pamusoro uye kuburitsa zvisiri izvo "kunze-kwe-kushivirira" kuverenga, kunyangwe chikamu chacho chakanyatsogadzirwa.
- Vibration Isolation: Iyo yekuyera nharaunda inofanirwa kuve yega. Nheyo yeZHHIMG, inoratidzira imwe-mita-yakakora anti-vibration kongiri pasi uye 2000 mm-yakadzika mugero wekuzviparadzanisa nevamwe, inoderedza kwekunze seismic uye mechaniki kupindira, kuve nechokwadi kuti kuyerwa kunotorwa pane muviri wakamira zvechokwadi.
4. Kusarudzwa: Kusarudza Yakarurama Metrology Tool
Chekupedzisira, chiridzwa chekuyeresa chakakodzera chinofanira kusarudzwa zvichienderana negiredhi rinodiwa chairo uye geometry yechikamu. Hapana chishandiso chimwechete chakanakira basa rega rega.
- Flatness: Kune yakazara yakakwirira-chaiyo flatness uye geometric fomu, iyo Laser Interferometer kana yakakwirira-resolution Autocollimator (kazhinji inobatanidzwa neElectroniki Levels) inopa iyo inodiwa kugadzirisa uye kureba-kureba kurongeka.
- Kurongeka Kwenzvimbo: Kuti utarise kupfeka kwenzvimbo kana kudzokorora (Kudzokorora Kuverenga Kwakarurama), yakakwirira-chaiyo Electronic Levels kana LVDT/Capacitance Probes ine zvigadziriso kusvika ku0.1 μm zvakakosha.
Nekuomerera zvine hungwaru kune aya matanho ekugadzirira - kutonga kugadzikana kwekupisa, kuchengetedza utsanana, uye kuve nechokwadi cherutsigiro rwezvimiro - boka remainjiniya reZHHIMG rinovimbisa kuti zviyero zvekupedzisira zvezvikamu zvedu zvekupedzisira-chaizvo chiratidzo chechokwadi uye chakavimbika chehuchokwadi hwepasi rose hwakaunzwa nemidziyo yedu uye nyanzvi dzedu nyanzvi.
