Kodi Malo Anu Ofotokozera Ali Okhazikika Mokwanira Kukwaniritsa Zofunikira za Nanometer-Scale Metrology?

Mu mpikisano womwe ukupitilira wopita ku zinthu zazing'ono komanso kulekerera kwakukulu pakupanga zinthu padziko lonse lapansi—kuyambira kukonza zinthu za semiconductor mpaka kuzinthu zoyendera ndege—kufunika kwa malo ofotokozera osasunthika komanso olondola ndikofunikira kwambiri. Mbale yakuda yolondola ya granite ikadali maziko ofunikira, osakambirana pa miyeso yonse, yomwe imagwira ntchito ngati "zero point" yomwe imatsimikizika kuti khalidwe ndi labwino. Koma ndi njira zambiri zomwe zilipo, kodi mainjiniya ndi akatswiri a metro angatsimikizire bwanji zomwe asankha?mbale ya pamwambaKodi ndi yokhazikika mokwanira kuti ikwaniritse zosowa zamakono za sub-micron?

Yankho lake lili pomvetsetsa kusiyana kwakukulu pakati pa granite wamba ndi granite wakuda wolondola kwambiri, wosankhidwa ndi kupangidwa kuti agwiritsidwe ntchito poyesa zinthu mwaukadaulo.

Chofunika cha Black Granite: Chifukwa Chake Kuchulukana Kuli Kofunika

Maziko a mbale iliyonse yapamwamba kwambiri ndi zinthu zopangira. Ngakhale kuti kugwiritsa ntchito kosavuta kungalole kugwiritsa ntchito miyala ya granite yowala kapena miyala ya marble, kulondola kwambiri kumafuna chinthu chokhala ndi mawonekedwe apadera, monga gabbro wakuda wokhuthala kwambiri.

Mwachitsanzo, granite yathu yakuda ya ZHHIMG®, ili ndi kukhuthala kwakukulu kofikira 3100 kg/m³. Khalidweli ndi lofunika kwambiri, chifukwa kukhuthala kwakukulu kumagwirizana mwachindunji ndi miyezo iwiri yofunika kwambiri ya magwiridwe antchito:

1. Kulimba ndi Kulimba: Chipangizo chokhuthala chimakhala ndi Young's Modulus yapamwamba, zomwe zimapangitsa kuti mbale ya granite yolondola kwambiri ikhale yolimba kwambiri ku kupotoka ndi kusinthika ikathandizira katundu wolemera (monga ma CMM akuluakulu kapena zinthu zolemera). Kulimba kumeneku kumatsimikizira kuti pamwamba pake polumikizana bwino pamakhalabe kulekerera kwake kosalala pakapita nthawi, ngakhale pakapanikizika kwambiri.

2. Kuchepetsa Kugwedezeka: Kapangidwe kake kovuta komanso kokhuthala kamapereka mawonekedwe abwino kwambiri ochepetsera kugwedezeka poyerekeza ndi chitsulo kapena chitsulo chopangidwa ndi chitsulo. Izi ndizofunikira kwambiri m'zipinda zamakono zowunikira, komwe mbale ya granite iyenera kuyamwa bwino kugwedezeka kochepa kuchokera ku phokoso lachilengedwe kapena makina apafupi, kuwaletsa kuti asasinthe miyeso yovuta.

Kuphatikiza apo, granite wakuda wapamwamba uyu mwachilengedwe amawonetsa kutentha kochepa kwambiri. M'malo owunikira kutentha komwe kumayendetsedwa ndi kutentha, izi zimachepetsa kusintha kwa mawonekedwe komwe kumachitika chifukwa cha kutentha kotsalira kuchokera ku gawo lomwe likuyesedwa kapena kusinthasintha pang'ono kwa kutentha kwa mpweya, kuonetsetsa kuti kukhazikika kofunikira pakuyeza mulingo wa nanometer.

Kupanga Nanometer: Njira Yopangira

Kukwaniritsa kusalala kofunikira pa mbale yakuda yolondola ya granite pamwamba—nthawi zambiri mpaka Giredi AAA (yofanana ndi DIN 876 Giredi 00 kapena 0)—ndi kalasi yabwino kwambiri yomaliza zinthu zopangidwa ndiukadaulo. Ndi njira yomwe imadalira zomangamanga zapadera komanso kulowererapo kwa anthu aluso kwambiri.

Timagwiritsa ntchito malo akuluakulu, olamulidwa ndi nyengo, komanso otetezedwa ku kugwedezeka, okhala ndi pansi pa konkire yolimba ndi ngalande zozungulira zotsutsana ndi kugwedezeka, kuti titsimikizire kuti zinthu zikuyenda bwino kwambiri panthawi yomaliza. Kupera kwakukulu kumayendetsedwa ndi makina odziwika padziko lonse lapansi, olemera (monga makina athu opera a ku Taiwan a Nant), omwe amatha kukonza mabuloko akuluakulu.

Komabe, gawo lomaliza komanso lofunika kwambiri ndi kugwirana ndi manja mosamala. Gawoli limachitidwa ndi akatswiri aluso omwe ali ndi zaka zambiri akugwira ntchito, omwe mayankho awo ogwira mtima komanso luso lawo lolondola limawathandiza kuchotsa zinthu zomwe zili pamlingo wa sub-micron. Ukadaulo uwu wa anthu umasintha mbaleyo kukhala yotsimikizika padziko lonse lapansi, yolunjika bwino.

Chakuda chilichonsembale yolondola ya granite pamwambaimatsimikiziridwa bwino pogwiritsa ntchito zida zoyezera zomwe zimatsata, kuphatikiza ma interferometer a laser a Renishaw ndi ma WYLER electronic levels. Izi zimatsimikizira kuti kusalala, kuwongoka, ndi kulondola kobwerezabwereza kwa kuwerenga kumakwaniritsa kapena kupitirira miyezo yovuta kwambiri (monga ASME, DIN, kapena JIS), ndi kutsata kubwerera ku mabungwe apadziko lonse lapansi.

Kugwiritsa Ntchito: Muyezo Wofotokozera wa Universal

Kukhazikika kwapamwamba komanso kulondola kotsimikizika kwa mbale yakuda ya granite pamwamba kumapangitsa kuti ikhale muyezo wofunikira pafupifupi m'makampani onse apamwamba:

• Metrology ndi Quality Control: Imagwira ntchito ngati maziko oyambira a zida zonse zowunikira, kuphatikiza ma CMM, makina oyezera makanema, ndi ma comparator a kuwala, zomwe zimapangitsa kuti pakhale njira yopanda cholakwika chilichonse yoyezera ndi kuyang'anira.

• Kukonza Molondola: Kumagwiritsidwa ntchito ngati malo owonetsera pokonza ndi kulumikiza zida zamakina molondola kwambiri, mabenchi owunikira, ndi magawo oyenda molunjika (kuphatikizapo makina onyamula mpweya) pa ntchito za semiconductor ndi aerospace.

• Ma Lab Oyezera: Ma plate a Giredi 00 ndi ofunikira kwambiri poyezera zida zazing'ono zoyezera, zoyezera kutalika, ndi milingo yamagetsi, zomwe zimagwira ntchito ngati njira yodziwira bwino mu kachitidwe ka calibration.

Pomaliza, ndalama zomwe zayikidwa mu mbale yapamwamba kwambiri ya granite yolondola kwambiri ndi ndalama zomwe zayikidwa mu mtundu wotsimikizika. Zimateteza kulondola koyambira komwe kumafunika kuti mupikisane mu gawo lopanga zinthu molondola kwambiri, kuonetsetsa kuti muyeso wanu siwolondola kokha komanso wosavuta kutsatira komanso wodalirika kwa zaka zikubwerazi.
