Funso Lokhudza Kusinthana—Kodi Mapulatifomu Olondola a Polymer Angalowe M'malo mwa Granite mu Metrology Yaing'ono?

Chuma Chabodza Chokhudza Kulowa M'malo mwa Zinthu Zachilengedwe

Mu dziko la kupanga zinthu molondola, kufunafuna njira zotsika mtengo kumakhala kosalekeza. Pa mabenchi ang'onoang'ono owunikira kapena malo oyesera am'deralo, funso nthawi zambiri limabuka: Kodi Pulatifomu yamakono ya Polymer (Plastiki) Precision Platform ingalowe m'malo mwa Pulatifomu yachikhalidwe ya Granite Precision, ndipo kodi kulondola kwake kukwaniritse miyezo yofunikira ya metrology?

Ku ZHHIMG®, timadziwa bwino za maziko olondola kwambiri ndipo timamvetsetsa kusintha kwa uinjiniya. Ngakhale kuti zipangizo za polima zimapereka ubwino wosatsutsika pa kulemera ndi mtengo, kusanthula kwathu kumatsimikiza kuti pa ntchito iliyonse yomwe imafuna kukhazikika kwa nthawi yayitali kapena kusalala kwa nanometer, pulasitiki singathe kulowa m'malo mwa granite wokhuthala kwambiri.

Kukhazikika kwa Pakati: Kumene Polymer Yalephera Kuyesa Kolondola

Kusiyana pakati pa granite ndi polima sikutanthauza kungokhala kwa kuchulukana kapena mawonekedwe; kuli m'makhalidwe ofunikira omwe sangakambirane kuti pakhale kulondola kwa kalasi ya metrology:

1. Kukulitsa Kutentha (CTE): Ichi ndi chofooka chachikulu kwambiri cha zinthu za polima. Mapulasitiki ali ndi Coefficient of Thermal Expansion (CTE) nthawi zambiri kuposa granite. Ngakhale kusinthasintha pang'ono kwa kutentha kwa chipinda, komwe kumachitika kawirikawiri kunja kwa zipinda zoyera za asilikali, kumayambitsa kusintha kwakukulu, kwadzidzidzi kwa pulasitiki. Mwachitsanzo, ZHHIMG® Black Granite imasunga kukhazikika kwapadera, pomwe nsanja ya pulasitiki imapuma nthawi zonse ndi kusintha kwa kutentha, zomwe zimapangitsa kuti muyeso wovomerezeka wa sub-micron kapena nanometer usadalire.
2. Kuyenda Kwakanthawi (Kukalamba): Mosiyana ndi granite, yomwe imalimbitsa kupsinjika kudzera mu kukalamba kwachilengedwe kwa miyezi ingapo, ma polima mwachibadwa amakhala osalala. Amawonetsa kuyendayenda kwakukulu, zomwe zikutanthauza kuti amasinthasintha pang'onopang'ono komanso kosatha pansi pa katundu wokhazikika (ngakhale kulemera kwa sensa yowunikira kapena chogwirira). Kusintha kosatha kumeneku kumawononga kusalala koyambirira kovomerezeka pakatha milungu kapena miyezi yogwiritsidwa ntchito, zomwe zimapangitsa kuti pakhale kukonzedwanso kokwera mtengo komanso kovomerezeka.
3. Kuchepetsa Kugwedezeka: Ngakhale mapulasitiki ena opangidwa ndi akatswiri amapereka mphamvu zabwino zochepetsera kugwedezeka, nthawi zambiri sakhala ndi kukhazikika kwakukulu kwa inertial komanso kukangana kwakukulu kwamkati kwa granite yolimba kwambiri. Pakuyeza kwamphamvu kapena kuyesa pafupi ndi magwero ogwedezeka, kuchuluka kwakukulu kwa granite kumapereka kuyamwa kwabwino kwambiri kwa kugwedezeka komanso malo owonetsera chete.

Kukula Kochepa, Zofunikira Zazikulu

Mfundo yakuti nsanja "yaing'ono" siikhudzidwa kwambiri ndi mavuto amenewa ndi yolakwika kwambiri. Pakuwunika pang'ono, kufunikira kolondola nthawi zambiri kumakhala kwakukulu. Gawo lowunikira laling'ono lingakhale loyang'aniridwa ndi microchip kapena ultra-fine optics, komwe gulu lololera limakhala lolimba kwambiri.

Ngati nsanja ya 300mm×300mm ikufunika kuti ikhale yosalala ya ±1 micron, chipangizocho chiyenera kukhala ndi CTE yotsika kwambiri komanso kuchuluka kwa kukwera. Ichi ndichifukwa chake Precision Granite ikadali chisankho chomaliza, mosasamala kanthu za kukula kwake.

Chigamulo cha ZHHIMG®: Sankhani Kukhazikika Kotsimikizika

Pa ntchito zosalondola kwenikweni (monga kusonkhanitsa koyambira kapena kuyesa kwamakina), nsanja za polima zitha kupereka njira yosinthira kwakanthawi komanso yotsika mtengo.

Komabe, pa ntchito iliyonse yomwe:

• Miyezo ya ASME kapena DIN iyenera kutsatiridwa.
• Kulekerera kuli pansi pa ma microns 5.
• Kukhazikika kwa nthawi yayitali sikungakambirane (monga masomphenya a makina, CMM staging, kuyesa kwa maso).

...ndalama zomwe zayikidwa mu nsanja ya ZHHIMG® Black Granite ndi ndalama zomwe zayikidwa mu kulondola kotsimikizika komanso kolondola. Timalimbikitsa mainjiniya kuti asankhe zipangizo kutengera kukhazikika ndi kudalirika, osati kungosunga ndalama zoyambira zokha. Njira yathu yopangira zinthu ya Quad-Certified imatsimikizira kuti mumalandira maziko olimba kwambiri padziko lonse lapansi.
