Tingava Sei Nechokwadi Chekuti Zvakagadzirwa Zvakanaka? Pfungwa Dzakakosha Dzekugadzirira Usati Wayera Zvikamu zveGranite

Muinjiniya wepamusoro-soro, chikamu chegranite ndicho chinhu chikuru chinoratidza kugadzikana kwemidziyo inoshanda pachiyero che micro ne nanometer. Zvisinei, kunyange chinhu chakasimba zvikuru—granite yedu nhema yeZHHIMG® ine density yakakura—inogona chete kupa simba rayo rakazara kana maitiro ekuyera pachawo akatarisirwa nesainzi.

Mainjiniya nenyanzvi dzemetro vanovimbisa sei kuti mhedzisiro yekuyera ndeyechokwadi? Kuwana mhedzisiro chaiyo uye inodzokororwa panguva yekuongorora uye kusimbiswa kwekupedzisira kwematombo emuchina wegranite, mabheyaringi emhepo, kana zvivakwa zveCMM kunoda kutariswa zvakanyanya kune zvese zvisati zvabatwa nechinhu chekuyera pamusoro. Kugadzirira uku kunowanzo kuve kwakakosha semuchina wekuyera pachawo, kuve nechokwadi chekuti mhedzisiro yacho inoratidza zvechokwadi geometry yechikamu, kwete zvinhu zvezvakatipoteredza.

1. Basa Rakakosha reKugadzirisa Kupisa (Nguva Yekunyura Mumvura)

Granite ine Coefficient of Thermal Expansion (COE) yakaderera zvikuru, kunyanya kana ichienzaniswa nesimbi. Asi, chero chinhu, kusanganisira granite ine density yakakura, inofanira kunge yakagadzikiswa nekupisa kumhepo iri mumhepo uye mudziyo wekuyera usati watanga kuongorora. Izvi zvinozivikanwa senguva yekunyura.

Chikamu chikuru chegranite, kunyanya icho chichangobva kutamiswa kubva pasi pefekitori kuenda ku lab yakatsaurirwa metrology, chichava nekupisa kwemvura - musiyano wekupisa pakati pepakati payo, pamusoro, uye hwaro. Kana kuyerwa kukatanga nguva isati yakwana, granite inokura zvishoma nezvishoma kana kupfupika sezvainoenzana, zvichikonzera kutenderera kunoramba kuripo mukuverenga.

• Mutemo weChigunwe: Zvikamu zvakanyatsonaka zvinofanirwa kugara munzvimbo yekuyera—dzimba dzedu dzekuchenesa dzinodzora tembiricha nehunyoro—kwenguva yakareba, kazhinji maawa makumi maviri nemana kusvika makumi manomwe nemaviri, zvichienderana nehuremu uye ukobvu hwechikamu chacho. Chinangwa ndechekuwana kuenzana kwekupisa, kuve nechokwadi chekuti chikamu chegranite, mudziyo wekuyera (senge laser interferometer kana electronic level), uye mhepo yese iri patembiricha inozivikanwa pasi rose (kazhinji 20℃).

2. Kusarudza uye Kuchenesa Pamusoro: Kubvisa Muvengi Wekururama

Tsvina, guruva, uye marara ndizvo vavengi vakuru vekuyerwa kwakarurama. Kunyangwe chidimbu cheguruva chidiki-diki kana chigunwe chakasara chinogona kugadzira kukwirira kwakamira kunoratidza zvisirizvo kukanganisa kwema micrometer akati wandei, zvichikanganisa zvakanyanya kuyerwa kwekusatsetseka kana kutwasuka.

Chero chipi zvacho chekuongorora, chinoratidza chiedza, kana mudziyo wekuyera usati waiswa pamusoro:

• Kuchenesa Zvakakwana: Nzvimbo iri pamusoro pechinhu, ingave iri reference plane kana kuti mounting pad ye linear rail, inofanira kucheneswa zvakanaka uchishandisa wipe yakakodzera, isina lint uye cleansing agent ine hutsanana hwakawanda (kazhinji industrial alcohol kana granite cleaner).
• Pukuta Zvishandiso: Zvakakoshawo kuchenesa zvishandiso zvekuyera pachazvo. Magirazi ekuisa chiedza, mabhesi ezvishandiso, uye matipi ekuongorora anofanira kunge akachena kuti ave nechokwadi chekuti anobata zvakanaka uye kuti nzira yekuona ionekwe zvakanaka.

3. Kunzwisisa Rutsigiro uye Kusunungurwa Kwekushushikana

Matsigiro anoita chikamu chegranite panguva yekuyerwa akakosha. Zvivakwa zvegranite zvakakura, zvinorema zvakagadzirwa kuti zvirambe zvakaita sejiyomethri yazvo kana zvichitsigirwa panzvimbo dzakatarwa, dzakaverengerwa nemasvomhu (kazhinji zvichibva papoindi dzeAiry kana Bessel kuti zvive zvakati sandara).

• Kuisa Kwakarurama: Kuongororwa kunofanirwa kuitwa nechikamu chegranite chakarara pazvitsigiro zvakatarwa nepurani yeinjiniya. Nzvimbo dzekutsigira dzisiridzo dzinogona kukonzera kushushikana kwemukati uye kutsauka kwechimiro, zvichikanganisa pamusoro uye zvichiita kuti kuverenga "kusashivirira" kusanyatsojeka, kunyangwe chikamu chacho chakagadzirwa zvakanaka.
• Kuzviparadzanisa Nekuzunguzika: Nzvimbo yekuyera inofanira kuparadzaniswa pachayo. Nheyo yeZHHIMG, ine pasi rekongiri rinodzivirira kuzunguzika rine ukobvu hwemita imwe uye gomba rekuparadzanisa rakadzika 2000 mm, inoderedza kupindira kwekunze kwekudengenyeka kwenyika uye kwemakanika, zvichiita kuti kuyerwa kuitwe panzvimbo isina kugadzikana zvechokwadi.

4. Sarudzo: Kusarudza Chishandiso Chekuyera Zvinhu Chakakodzera

Chekupedzisira, chiyereso chakakodzera chinofanira kusarudzwa zvichienderana negiredhi rakakodzera uye geometry yechikamu chacho. Hapana chiyereso chimwe chete chakakwana pabasa rega rega.

• Kufara: Kuti zvive zvakati twasu uye chimiro chejometri zvive zvakanyatsonaka, Laser Interferometer kana kuti high-resolution Autocollimator (inowanzo batanidzwa neElectronic Levels) inopa resolution inodiwa uye kururama kwenguva refu.
• Kururama Kwenzvimbo: Kuti utarise kupfeka kana kudzokorora kwenzvimbo (Kudzokorora Kururama Kwekuverenga), maElectronic Levels akanyatsogadzirwa kana kuti maLVDT/Capacitance Probes ane resolution yakadzika kusvika ku0.1 μm akakosha.

Nekunyatsotevedzera matanho aya ekugadzirira—kutarisira kugadzikana kwekupisa, kuchengetedza kuchena, uye kuona kuti chimiro chayo chakasimba—chikwata chemainjiniya cheZHHIMG chinovimbisa kuti kuyerwa kwekupedzisira kwezvinhu zvedu zvakanyatsonaka kunoratidza chokwadi uye chakavimbika chekururama kwepasi rose kunounzwa nezvinhu zvedu nenyanzvi dzedu dzehunyanzvi.
