Funso Lolowa m'malo—Kodi Mapulatifomu Olondola a Polima Angalowe M'malo mwa Granite mu Small-Scale Metrology?

Chuma Chonama cha Kusintha Zinthu

M'dziko lopanga molondola, kufunafuna mayankho otsika mtengo kumakhala kosalekeza. Pamabenchi oyendera ang'onoang'ono kapena malo oyesera apafupipafupi, funso limadza nthawi zambiri: Kodi Platform yamakono ya Polima (Plasitiki) Precision ingalowe m'malo mwa Platform yachikhalidwe ya Granite Precision Platform, ndipo kulondola kwake kungakwaniritse miyezo yofunikira ya metrology?

Ku ZHHIMG®, timakhazikika pamaziko olondola kwambiri ndikumvetsetsa zamalonda aukadaulo. Ngakhale zida za polima zimapereka maubwino osatsutsika pa kulemera ndi mtengo wake, kusanthula kwathu kumatsimikizira kuti pakugwiritsa ntchito kulikonse komwe kumafunikira kukhazikika kwanthawi yayitali kapena kukhazikika kwa nanometer, pulasitiki silingalowe m'malo mwa granite wokwera kwambiri.

Kukhazikika Kwambiri: Kumene Polima Imalephera Kuyesa Kwambiri

Kusiyana pakati pa granite ndi polima sikungofanana ndi kachulukidwe kapena mawonekedwe; Zili muzinthu zofunikira kwambiri zomwe sizingakambirane zolondola pamlingo wa metrology:

1. Kukula kwa Thermal (CTE): Uku ndiye kufooka kwakukulu kwambiri kwa zida za polima. Pulasitiki imakhala ndi Coefficient of Thermal Expansion (CTE) nthawi zambiri kuposa ya granite. Ngakhale kusinthasintha kwakung'ono kwa kutentha kwa chipinda, kumene kumakhala kofala kunja kwa zipinda zoyera za asilikali, kumapangitsa kuti pulasitiki isinthe kwambiri. Mwachitsanzo, ZHHIMG® Black Granite imakhalabe yokhazikika, pamene nsanja ya pulasitiki "imapuma" nthawi zonse ndi kusintha kwa kutentha, zomwe zimapangitsa kuti miyeso yovomerezeka ya micron kapena nanometer ikhale yosadalirika.
2. Kukula Kwa Nthawi Yaitali (Kukalamba): Mosiyana ndi granite, yomwe imapangitsa kukhazikika kwa nkhawa kudzera mu ukalamba wachilengedwe wa miyezi ingapo, ma polima amakhala owoneka bwino. Amawonetsa kukwawa kwakukulu, kutanthauza kuti amapunduka pang'onopang'ono komanso kosatha pansi pa katundu wokhazikika (ngakhale kulemera kwa sensor ya kuwala kapena chojambula). Kupindika kosatha kumeneku kumasokoneza kukhazikika kotsimikizika koyamba pakadutsa milungu kapena miyezi yogwiritsidwa ntchito, zomwe zimafunikira kukonzanso pafupipafupi komanso kokwera mtengo.
3. Vibration Damping: Ngakhale mapulasitiki opangidwa ndi injiniya amapereka zinthu zabwino zochepetsera, nthawi zambiri amakhala opanda kukhazikika kwamphamvu komanso kukangana kwakukulu kwamkati kwa granite yolimba kwambiri. Pamiyezo yosunthika kapena kuyesa pafupi ndi komwe kugwedezeka, kuchuluka kwa granite kumapereka mayamwidwe apamwamba komanso ndege yolondolerapo.

Kukula Kwakung'ono, Zofunika Zazikulu

Mtsutso wakuti nsanja "yaing'ono" ndiyosavuta kukhudzidwa ndi izi ndi zolakwika kwenikweni. Poyang'ana pang'ono, chofunikira cholondola nthawi zambiri chimakhala chokwera. Gawo laling'ono loyang'anira litha kuperekedwa pakuwunika kwa ma microchip kapena ma Ultra-fine Optics, pomwe gulu la tolerance ndi lolimba kwambiri.

Ngati nsanja ya 300mm×300mm ikufunika kuti ikhale ± 1 micron flatness, zinthuzo ziyenera kukhala ndi CTE yotsika kwambiri komanso kukwawa. Ichi ndichifukwa chake Precision Granite imakhalabe chisankho chotsimikizika, mosasamala kanthu za kukula kwake.

Chigamulo cha ZHHIMG®: Sankhani Kukhazikika Kotsimikizika

Pazochita zolongosoka kwambiri (mwachitsanzo, kuyesa koyambira kapena kuyezetsa mwaukali), mapulaneti a polima atha kupereka choloŵa m'malo kwakanthawi, chotsika mtengo.

Komabe, pakugwiritsa ntchito kulikonse komwe:

• Miyezo ya ASME kapena DIN iyenera kukwaniritsidwa.
• Kulekerera kuli pansi pa ma microns 5.
• Kukhazikika kwanthawi yayitali sikungakambirane (mwachitsanzo, masomphenya a makina, masitepe a CMM, kuyesa kwa kuwala).

…ndalama mu nsanja ya ZHHIMG® Black Granite ndi ndalama zotsimikizika, zolondola komanso zolondola. Timalimbikitsa mainjiniya kuti asankhe zida potengera kukhazikika komanso kudalirika, osati kungopulumutsa ndalama zoyambira. Kupanga kwathu kwa Quad-Certified kumatsimikizira kuti mumalandira maziko okhazikika padziko lonse lapansi.
