Kudziwa Kugwirana ndi Manja ndi Kuyeza kwa Laser: Kukwaniritsa Kusalala kwa Nanometer mu Kupanga Zinthu Zambiri

Makina opukusira amakono a computer numerally control (CNC) ndi odabwitsa kwambiri pamakina odzipangira okha. Zipangizo zazikulu zopukusira, monga makina opukusira pamwamba olemera a 6000 mm, zimatha kukonza mofulumira nsanja zachitsulo ndi zopanda zitsulo kuti zikhale zolimba. Komabe, pamene zofunikirazo zimafuna kuti nanometer ikhale yosalala pazitali zazitali, makina opukusira amafika pamalire ake enieni.

Kukonzanso kwakukulu kwa zigawo zolondola za granite, mbale zapamwamba, ndi m'mbali zowongoka kumafuna kuphatikiza kwa malingaliro a anthu ndi laser interferometry.

Malire a Kupera kwa Makina

Ngakhale zapamwamba kwambiriMakina opukutira a CNCali ndi zolakwika zamakina. Kuthamanga kwa spindle, kupotoka kwa kapangidwe ka makina, ndi kusintha kwa kutentha kwa microscopic mu coolant kumayambitsa mawonekedwe a mafunde ozungulira pa workpiece ya pansi. Zizindikiro zamakina izi zimaletsa makina wamba kuti asadutse chotchinga cha sub-micron pazinthu zazikulu.

 

Kuti mupeze mbiri yeniyeni ya nanometer, gawoli liyenera kukonzedwa mwapadera ndi manja, njira yotchedwa hand-lapping.

Njira Yogwirira Manja: Kuyankha Kogwira Pang'ono-Level

Kulumikiza ndi manja ndi luso lapadera la makina komwe akatswiri amagwiritsa ntchito mankhwala okhwima ndi zomangira zapadera kuti achotse zinthu pamalo okwera padenga.pamwamba pa granite.

• Kuzindikira Kugwira Moyenera: Akatswiri aluso ali ndi luso lotha kugwira lomwe lakhalapo kwa zaka zambiri akugwiritsa ntchito manja. Amatha kuzindikira kusinthasintha kwa malo mpaka ma micrometer a manambala amodzi mwa kumva kukana ndi kukangana kwa chipika cholumikizira.

• Kukonza Kobwerezabwereza: Njirayi ndi yobwerezabwereza. Katswiri amadutsa pamwamba, amalola kuti zinthuzo zikhazikike bwino, amayesa malo pogwiritsa ntchito zida zamagetsi zoyezera, ndikubwereza njirayi mpaka malo omwe akufuna atafika.

• Kusalala kwa Nanometer: Kudzera mu njira iyi yamanja, malo okwera amachepetsedwa pang'onopang'ono, zomwe zimapangitsa kuti ma granite pamwamba pa ma plate akuluakulu azitha kufika pamlingo wa nanometer—zomwe sizingatheke ndi mawilo opukutira okha.

Kutsimikizira Kulondola kudzera mu Advanced Metrology ndi Traceability

Luso lamanja siligwira ntchito popanda kutsimikizira kwathunthu muyeso. Kuti zitsimikizire malo ozungulira ndi manja, malo opangira zinthu amagwiritsa ntchito zida zapamwamba zoyezera zomwe zimayenderana ndi miyezo yapadziko lonse lapansi.

• Laser Interferometry: Machitidwe monga Renishaw laser Interferometer amagwiritsidwa ntchito pojambula zolakwika za mzere, angular, ndi flatness za njira zotsogolera ndi matabwa omangira pamtunda wautali (mpaka 20 m).

• Kusiyanitsa kwa Ma Electronic Leveling: Ma electronic level a Swiss WYLER amagwiritsidwa ntchito m'ma differential pairs kuti agwire angular pitch ndi roll deviations mpaka 0.5μm.

• Kuyang'anira Ma Micro-Topography: Zizindikiro zoyimbira za Mahr (0.5μm resolution), ma caliper a digito a Mitutoyo, ndi zoyesa kuuma kwa pamwamba zolondola kwambiri zimatsimikizira kuti kapangidwe kake kakang'ono ka granite kakugwirizana ndi zomwe zafotokozedwa m'chipinda choyera.

Kufunika kwa Kutsata Kulondola kwa Dziko Lonse

Muyeso umakhala wovomerezeka pokhapokha ngati ungatsimikizidwe ndi chipani chachitatu chodziyimira pawokha. Zipangizo zonse zapamwamba zoyezera ziyenera kukhala ndi ziphaso zovomerezeka zoyezera zomwe zimaperekedwa ndi mabungwe ovomerezeka am'deralo, monga Shandong Institute of Metrology kapena Jinan Institute of Metrology.

Chofunika kwambiri, muyezo uliwonse wogwiritsidwa ntchito mufakitale uyenera kukhala ndi unyolo wosasweka wotsatira kubwerera ku National Institute of Metrology (NIM). Izi zimatsimikizira kuti pamene mainjiniya ogula zinthu ochokera ku Apple, Samsung, kapena Bosch akuwunikanso lipoti loyang'anira gawo la granite la ZHHIMG®, detayo imakhala yovomerezeka malinga ndi mapangano apadziko lonse lapansi a metrology.
