Kodi Tingatsimikizire Bwanji Kuti Ndi Zolondola? Mfundo Zofunikira Zokonzekera Musanayese Zigawo za Granite

Mu uinjiniya wolondola kwambiri, gawo la granite ndiye maziko abwino kwambiri, omwe amapereka maziko a kukhazikika kwa zida zomwe zimagwira ntchito pa sikelo ya micro ndi nanometer. Komabe, ngakhale zinthu zokhazikika kwambiri—granite yathu yakuda ya ZHHIMG® yokhala ndi kuchuluka kwakukulu—ingathe kupereka mphamvu zake zonse ngati njira yoyezera yokha iyendetsedwa mwanzeru.

Kodi mainjiniya ndi akatswiri a za metro amatsimikiza bwanji kuti zotsatira za muyeso ndi zolondola? Kupeza zotsatira zolondola komanso zobwerezabwereza panthawi yowunikira ndi kutsimikizira komaliza kwa maziko a makina a granite, ma air bearing, kapena kapangidwe ka CMM kumafuna chisamaliro chapadera pa tsatanetsatane chida choyezera chisanakhudze pamwamba. Kukonzekera kumeneku nthawi zambiri kumakhala kofunikira kwambiri monga zida zoyezera zokha, kuonetsetsa kuti zotsatira zake zikuwonetsadi momwe gawolo lilili, osati zinthu zachilengedwe.

1. Udindo Wofunika Kwambiri wa Kutentha (Nthawi Yomwe Madzi Amalowa M'thupi)

Granite ili ndi Coefficient of Thermal Expansion (COE) yotsika kwambiri, makamaka poyerekeza ndi zitsulo. Komabe, zinthu zilizonse, kuphatikizapo granite yochuluka kwambiri, ziyenera kukhazikika pa kutentha kwa mpweya wozungulira ndi chida choyezera musanayambe kutsimikizira. Izi zimadziwika kuti nthawi yonyowa.

Gawo lalikulu la granite, makamaka lomwe langosamutsidwa kumene kuchokera pansi pa fakitale kupita ku labu yodziwika bwino ya metrology, lidzakhala ndi ma gradient a kutentha—kusiyana kwa kutentha pakati pa pakati pake, pamwamba pake, ndi pansi pake. Ngati kuyeza kumayamba msanga, granite idzakula pang'onopang'ono kapena kufupika pamene ikugwirizana, zomwe zimapangitsa kuti kuwerenga kupitirire.

• Lamulo Lalikulu: Zigawo zolondola ziyenera kukhala m'malo oyezera—zipinda zathu zoyera zolamulidwa ndi kutentha ndi chinyezi—kwa nthawi yayitali, nthawi zambiri maola 24 mpaka 72, kutengera kulemera ndi makulidwe a gawolo. Cholinga chake ndi kukwaniritsa kutentha koyenera, kuonetsetsa kuti gawo la granite, chipangizo choyezera (monga laser interferometer kapena electronic level), ndipo mpweya uli pa kutentha kodziwika padziko lonse lapansi (nthawi zambiri 20℃).

2. Kusankha ndi Kuyeretsa Malo: Kuchotsa Mdani Wolondola

Dothi, fumbi, ndi zinyalala ndi adani akuluakulu a muyeso wolondola. Ngakhale tinthu tating'onoting'ono ta fumbi kapena chala chotsala chingapangitse kutalika koyima komwe kumawonetsa cholakwika cha ma micrometer angapo, zomwe zimapangitsa kuti muyeso wa kusalala kapena kuwongoka ukhale wovuta kwambiri.

Chisadayambe kuyikidwapo choyezera chilichonse, chowunikira, kapena chida choyezera pamwamba:

• Kuyeretsa Bwino: Pamwamba pa chinthucho, kaya ndi malo owonetsera kapena malo oikirapo chingwe, payenera kutsukidwa mosamala pogwiritsa ntchito chopukutira choyenera, chopanda ulusi ndi chotsukira choyera kwambiri (nthawi zambiri mowa wa mafakitale kapena chotsukira granite chodzipereka).
• Pukutani Zida: Chofunikanso ndi kuyeretsa zida zoyezera zokha. Zowunikira, maziko a zida, ndi nsonga za probe ziyenera kukhala zoyera bwino kuti zitsimikizire kuti zikugwirizana bwino komanso kuti kuwala kukhale kolondola.

3. Kumvetsetsa Thandizo ndi Kutulutsa Kupsinjika Maganizo

Mmene gawo la granite limathandizira poyezera n'kofunika kwambiri. Nyumba zazikulu, zolemera za granite zimapangidwa kuti zisunge mawonekedwe ake akathandizidwa pamalo enaake, owerengedwa mwa masamu (nthawi zambiri kutengera malo a Airy kapena Bessel kuti zikhale zosalala bwino).

• Kuyimika Koyenera: Kutsimikizira kuyenera kuchitika pamene gawo la granite lili pa zothandizira zomwe zatchulidwa ndi pulani ya uinjiniya. Malo ochirikiza olakwika angayambitse kupsinjika kwamkati ndi kupotoka kwa kapangidwe, kupotoza pamwamba ndikupereka kuwerenga kolakwika "kosagwirizana", ngakhale gawolo litapangidwa bwino.
• Kudzipatula kwa Kugwedezeka: Malo oyezera ayenera kudzipatula okha. Maziko a ZHHIMG, okhala ndi pansi pa konkire wokhuthala mita imodzi komanso ngalande yodzipatula yakuya 2000 mm, amachepetsa kusokonezeka kwa zivomerezi ndi makina akunja, kuonetsetsa kuti muyesowo ukutengedwa pa thupi losasunthika kwenikweni.

4. Kusankha: Kusankha Chida Choyenera cha Metrology

Pomaliza, chida choyezera choyenera chiyenera kusankhidwa kutengera giredi yolondola yofunikira komanso mawonekedwe a gawolo. Palibe chida chimodzi chomwe chili choyenera ntchito iliyonse.

• Kusalala: Kuti chithunzi chikhale chosalala komanso cholondola kwambiri, Laser Interferometer kapena Autocollimator yokhala ndi resolution yapamwamba (nthawi zambiri yolumikizidwa ndi Electronic Levels) imapereka resolution yofunikira komanso kulondola kwakutali.
• Kulondola Kwakomweko: Pofuna kuwona kuwonongeka kwa malo kapena kubwerezabwereza (Kubwereza Kulondola Kwa Kuwerenga), Ma Levels Amagetsi Olondola Kwambiri kapena Ma LVDT/Capacitance Probes okhala ndi ma resolution otsika mpaka 0.1 μm ndi ofunikira.

Mwa kutsatira mosamala njira zokonzekera izi—kusamalira kukhazikika kwa kutentha, kusunga ukhondo, ndikuwonetsetsa kuti kapangidwe kake kali koyenera—gulu la mainjiniya la ZHHIMG likutsimikizira kuti miyeso yomaliza ya zigawo zathu zolondola kwambiri ndi chiwonetsero chenicheni komanso chodalirika cha kulondola kwapamwamba komwe kumaperekedwa ndi zipangizo zathu ndi akatswiri athu aluso.
