M'mawonekedwe apamwamba kwambiri a makina osindikizira a laser a picosecond-level laser, maziko, monga gawo lothandizira pazida, kusankha kwake kwazinthu kumatsimikizira kukhazikika kwa kulondola kwa kukonza. Granite ndi chitsulo chosungunuka ndi zinthu ziwiri zomwe zimagwiritsidwa ntchito popanga maziko. Nkhaniyi iyerekeza kuchokera kuzinthu zakuthupi, mfundo yochepetsera kulondola, ndi deta yogwiritsira ntchito, ndikupereka maziko asayansi okweza zida. ku
I. Kusiyanasiyana kwa Katundu: Lingaliro Lapansi la Kachitidwe Kolondola
Granite ndi mwala wachilengedwe woyaka moto, womwe umapangidwa ndi kutsekemera kwapafupi kwa mchere monga quartz ndi feldspar mkati. Amadziwika ndi mawonekedwe olimba komanso kuuma kwakukulu. Kachulukidwe kake kamakhala pakati pa 2.7 ndi 3.1g/cm³, ndipo coefficient of thermal expansion ndi yotsika kwambiri, pafupifupi (4-8) × 10⁻⁶/℃, yomwe imatha kukana kutengera kusintha kwa kutentha pakulondola kwa zida. Kuphatikiza apo, kapangidwe kake kakang'ono ka granite kamakhala ndi magwiridwe antchito abwino kwambiri, omwe amawapangitsa kuti azitha kuyamwa mwachangu mphamvu zakunjenjemera zakunja ndikuchepetsa kusokoneza kwa kugwedezeka pakukonza kulondola. ku
Chitsulo chachitsulo, monga zida zamafakitale, chimakhala ndi kachulukidwe pafupifupi 7.86g/cm³, mphamvu yopondereza kwambiri, koma ndiyotentha.
Nambala yowonjezera (pafupifupi 12×10⁻⁶/℃) ndi 1.5-3 nthawi ya granite. Kuphatikiza apo, pali zida za graphite mkati mwa chitsulo chosungunuka. Pogwiritsa ntchito nthawi yayitali, mapangidwewa angayambitse kupsinjika maganizo, kusokoneza kukhazikika kwa zinthuzo ndipo kenako kuchititsa kuchepa kwachangu. ku
Ii. Precision Attenuation Mechanism mu Picosecond-level Machining
Picosecond-level laser processing ili ndi zofunika kwambiri pakukhazikika kwa chilengedwe. Kupindika kulikonse pang'ono kwa zinthu zoyambira kudzakulitsidwa kukhala zotsatira zopangira. Kusinthasintha kwa kutentha, kugwedezeka kopangidwa ndi ntchito ya zipangizo, kutopa pansi pa katundu wa nthawi yaitali, ndi zina zotero, zonsezi ndizinthu zazikulu zomwe zimapangitsa kuti zisawonongeke. ku
Kutentha kukasintha, kukula kwa granite kumasintha pang'ono chifukwa cha kuchepa kwake kwa kuwonjezereka kwa kutentha. Kuchuluka kwamphamvu kwachitsulo chosungunuka kumapangitsa kuti mazikowo asinthe zomwe zimakhala zovuta kuzizindikira ndi maso. Kupindika kumeneku kudzakhudza mwachindunji kukhazikika kwa njira ya laser Optical ndikupangitsa kuti cholembacho chisinthe. Pankhani ya kugwedezeka, mawonekedwe apamwamba a granite amatha kutsitsa kugwedezeka kwa 100Hz mkati mwa masekondi 0.12, pomwe chitsulo chotayidwa chimafunikira masekondi 0.9. Pansi pa kugwedezeka kwamphamvu kwambiri, kulondola kwa zida zokhala ndi zitsulo zotayidwa kumakonda kusinthasintha. ku
Iii. Kuyerekeza kwa Precision Attenuation Data
Malinga ndi mayeso a mabungwe akatswiri, pa 8 maola picosecond laser cholemba ntchito mosalekeza, attenuation wa XY-axis malo kulondola kwa zipangizo ndi maziko granite ndi mkati ± 0.5μm. Kuchepetsa kulondola kwa zida zachitsulo choponyedwa kumafika ± 3μm, ndi kusiyana kwakukulu. M'malo ofananirako ndi kusintha kwa kutentha kwa 5 ℃, cholakwika cha kutentha kwa zida za granite ndi + 0.8μm zokha, pomwe zida zachitsulo zotayira zimafika + 12μm. ku
Kuphatikiza apo, malinga ndi momwe amagwiritsidwira ntchito nthawi yayitali, kuweruza molakwika kwa maziko a granite ndi 0.03% yokha, pomwe kusaganiziridwa molakwika kwazitsulo zachitsulo kumakhala 0.5% chifukwa cha kukhazikika kwamapangidwe. Deta iyi ikuwonetseratu kuti pansi pa zofunikira zowonongeka kwambiri za picosecond-level processing, ubwino wokhazikika wa maziko a granite ndi ofunika kwambiri. ku
Iv. Sinthani Malingaliro Ndi Mapulogalamu Othandiza
Kwa mabizinesi omwe amatsata kulondola kopitilira muyeso, kukweza maziko achitsulo chopangidwa ndi granite ndi njira yabwino yopititsira patsogolo magwiridwe antchito a zida. Panthawi yokonzanso, tcheru chiyenera kuperekedwa ku ndondomeko yolondola ya maziko a granite kuti atsimikizire kuti kutsetsereka kwapamwamba kumakwaniritsa zofunikira za mapangidwe. Nthawi yomweyo, kuphatikiza ndi zida zothandizira monga air flotation vibration isolation system, magwiridwe antchito a anti-vibration a zida amatha kukonzedwanso. ku
Pakadali pano, m'mafakitale monga kupanga zida za semiconductor chip ndi kukonza kwazinthu zowoneka bwino, makina ojambulira laser okhala ndi maziko a granite adalandiridwa bwino, kupititsa patsogolo zokolola zazinthu komanso kupanga bwino. Mwachitsanzo, wopanga zida zina zowoneka bwino atakweza zida zachitsulo, chiwongola dzanja cholondola chidakwera kuchoka pa 82% mpaka 97%, ndipo magwiridwe antchito adakulitsidwa kwambiri. ku
Pomaliza, pakukweza kwa makina oyika chizindikiro a picosecond-level laser, granite, yokhala ndi kukhazikika kwake kwamatenthedwe, magwiridwe antchito apamwamba komanso kuthekera kosunga nthawi yayitali, yakhala chisankho chabwino kwambiri kuposa chitsulo choponyedwa. Mabizinesi amatha kusankha zida zoyambira potengera zomwe akufuna komanso bajeti kuti akwaniritse kukweza kwa zida.
