Mu uinjiniya wolondola kwambiri, gawo la granite ndiye gawo lofunikira kwambiri, lomwe limapereka maziko okhazikika a zida zomwe zimagwira ntchito pamiyeso yaying'ono ndi nanometer. Komabe, ngakhale zinthu zokhazikika kwambiri - ZHHIMG® yathu yakuda ya granite yakuda kwambiri - imatha kupereka mphamvu zake zonse ngati kuyeza komweko kumayendetsedwa ndi sayansi.
Kodi mainjiniya ndi akatswiri a metrologist amawonetsetsa bwanji kuti zotsatira zake ndi zolondola? Kupeza zotsatira zolondola, zobwerezabwereza panthawi yoyendera ndikutsimikizira komaliza kwa maziko a makina a granite, ma air bear, kapena ma CMM amafunikira kusamalitsa mwatsatanetsatane chida choyezera chisanakhudze pamwamba. Kukonzekera kumeneku nthawi zambiri kumakhala kofunikira ngati zida zoyezera zokha, kuwonetsetsa kuti zotsatira zake zikuwonetsa geometry ya gawolo, osati zachilengedwe.
1. Udindo Wovuta Wa Kutentha kwa Matenthedwe (Nthawi Yotsekemera)
Granite ili ndi Coefficient yotsika kwambiri ya Thermal Expansion (COE), makamaka poyerekeza ndi zitsulo. Komabe, zinthu zilizonse, kuphatikiza granite yolimba kwambiri, ziyenera kukhazikika mumlengalenga komanso chida choyezera chisanayambe kutsimikizira. Izi zimatchedwa nthawi ya soak-out.
Chigawo chachikulu cha granite, makamaka chomwe chasamutsidwa posachedwa kuchokera ku fakitale kupita kumalo odzipatulira a metrology labu, chimakhala ndi mawotchi otentha - kusiyana kwa kutentha pakati pa phata lake, pamwamba, ndi maziko ake. Ngati muyeso uyamba nthawi isanakwane, granite imakula pang'onopang'ono kapena kutsika pang'onopang'ono pamene ikufanana, zomwe zimapangitsa kuti anthu aziwerenga mosalekeza.
- Ulamuliro wa Chala Chala Chala Chala: Zida zolondola ziyenera kukhala pamalo oyezera - zipinda zathu zoyeretsera kutentha ndi chinyezi - kwa nthawi yayitali, nthawi zambiri maola 24 mpaka 72, kutengera kuchuluka kwake ndi makulidwe ake. Cholinga chake ndikukwaniritsa kutentha kwapakati, kuwonetsetsa kuti gawo la granite, chipangizo choyezera (monga laser interferometer kapena mulingo wamagetsi), komanso mpweya wonse uli pa kutentha kovomerezeka padziko lonse lapansi (nthawi zambiri 20 ℃).
2. Kusankha Pamwamba ndi Kuyeretsa: Kuchotsa Mdani Wolondola
Dothi, fumbi, ndi zinyalala ndi adani amodzi okhawo a muyeso wolondola. Ngakhale tinthu tating'ono tating'ono tating'ono tating'onoting'ono kapena chotsalira chala chala chimatha kupanga kutalika koyimilira komwe kumawonetsa cholakwika cha ma micrometer angapo, kusokoneza kwambiri kuyeza kwa flatness kapena kuwongoka.
Musanafufuze chilichonse, chowunikira, kapena chida choyezera chimayikidwa pamwamba:
- Kuyeretsa Mokwanira: Pamwamba pake, kaya ndi ndege kapena choyikapo njanji, iyenera kutsukidwa bwino pogwiritsa ntchito chopukutira choyenera, chopanda zingwe komanso choyeretsera kwambiri (nthawi zambiri mowa wa m'mafakitale kapena chotsukira cha granite).
- Pukutani Pansi Zida: Chofunikanso ndikuyeretsa zida zoyezera zokha. Zowunikira, zoyambira zida, ndi maupangiri ofufuza ziyenera kukhala zopanda banga kuti zitsimikizire kulumikizana koyenera komanso njira yeniyeni yowonera.
3. Kumvetsetsa Thandizo ndi Kutulutsa Kupsinjika Maganizo
Momwe chigawo cha granite chimathandizira pakuyezera ndikofunikira. Zomangamanga zazikulu, zolemera za granite zimapangidwira kuti zisunge ma geometry awo zikathandizidwa pazigawo zenizeni, zowerengedwera masamu (nthawi zambiri kutengera ma Airy kapena Bessel kuti azitha kusalala bwino).
- Kuyika Moyenera: Kutsimikizira kuyenera kuchitika ndi gawo la granite lomwe likukhazikika pazothandizira zomwe zasankhidwa ndi pulani ya uinjiniya. Mfundo zothandizira zolakwika zingayambitse kupsinjika kwa mkati ndi kusokonezeka kwapangidwe, kupotoza pamwamba ndi kutulutsa kuwerenga kolakwika "kopanda kulolerana", ngakhale chigawocho chimapangidwa bwino.
- Kudzipatula kwa Vibration: Malo oyezera ayenera kukhala okha. Maziko a ZHHIMG, okhala ndi konkire yolimbana ndi kugwedezeka kwa mita imodzi ndi ngalande yodzipatula yozama ya 2000 mm, imachepetsa kusokoneza kwa zivomerezi zakunja ndi makina, kuwonetsetsa kuti muyeso umatengedwa pathupi lokhazikika.
4. Kusankha: Kusankha Chida Choyenera cha Metrology
Pomaliza, chida choyezera choyenera chiyenera kusankhidwa malinga ndi giredi yolondola yofunikira komanso geometry ya gawolo. Palibe chida chimodzi chomwe chili choyenera pa ntchito iliyonse.
- Flatness: Pazonse zomveka bwino za flatness ndi mawonekedwe a geometric, Laser Interferometer kapena Autocollimator yapamwamba (yomwe nthawi zambiri imagwirizanitsidwa ndi Electronic Levels) imapereka chigamulo chofunikira ndi kulondola kwautali.
- Zolondola Zam'deralo: Kuti muwone kuvala komweko kapena kubwerezabwereza (Kubwereza Kuwerenga Kulondola), Ma Level Electronics olondola kwambiri kapena LVDT/Capacitance Probes okhala ndi malingaliro otsika mpaka 0.1 μm ndiofunikira.
Potsatira mosamala masitepe okonzekerawa—kuwongolera kukhazikika kwa kutentha, kusunga ukhondo, ndi kuonetsetsa chithandizo cholondola—gulu la akatswiri a ZHHIMG limatsimikizira kuti miyeso yomaliza ya zigawo zathu zolondola kwambiri ndi chisonyezero chowona ndi chodalirika cha kulondola kwapadziko lonse koperekedwa ndi zipangizo zathu ndi akatswiri athu amisiri.
