Tsogolo la ultrafast mwatsatanetsatane Machining

Machining mwatsatanetsatane ndi gawo lofunikira pakupanga laser. Yapangidwa kuchokera ku ma lasers olimba a nanosecond obiriwira / a ultraviolet kupita ku ma lasers a picosecond ndi femtosecond, ndipo tsopano ma lasers othamanga kwambiri ndi omwe amapezeka kwambiri. Kodi chitukuko chamtsogolo cha makina a ultrafast precision chidzakhala chiyani?

Ma lasers a Ultrafast anali oyamba kutsatira njira yolimba yaukadaulo ya laser. Ma lasers olimba ali ndi mawonekedwe amphamvu yotulutsa, kukhazikika kwakukulu komanso kuwongolera bwino. Ndiwo kupitiliza kwa ma nanosecond/sub-nanosecond solid-state lasers, kotero ma lasers a picosecond femtosecond solid-state m'malo mwa nanoseconds solid-state lasers ndi zomveka. Ma fiber lasers ndi otchuka, ma lasers a ultrafast nawonso asunthira komwe kuli ma lasers, ndipo ma picosecond/femtosecond fiber lasers atuluka mwachangu, kupikisana ndi ma laser olimba kwambiri.

Chinthu chofunika kwambiri cha lasers ultrafast ndikukweza kuchokera ku infrared kupita ku ultraviolet. Infuraredi picosecond laser processing ali ndi zotsatira pafupifupi wangwiro mu magalasi kudula ndi kubowola, zigawo za ceramic, yopyapyala kudula, etc. Komabe, kuwala kwa ultraviolet pansi pa dalitso la ultra-short pulses akhoza kukwaniritsa "kuzizira processing" monyanyira, ndi kukhomerera ndi kudula pa zinthu ndi pafupifupi palibe zipsera, kukwaniritsa processing wangwiro.

Kakulidwe kaukadaulo ka ultra-short pulse laser ndikuwonjezera mphamvu , kuchoka pa 3 watts ndi 5 watts m'masiku oyambilira mpaka pamlingo wapano wa 100 watt. Pakalipano, kukonza molondola pamsika nthawi zambiri kumagwiritsa ntchito ma watts 20 mpaka mawati 50 amphamvu. Ndipo bungwe la Germany layamba kuthana ndi vuto la ma kilowatt-level ultrafast lasers. S&A ultrafast laser chiller series akhoza kukwaniritsa zoziziritsa za lasers kwambiri ultrafast pa msika, ndi kulemeretsa S&A chiller mankhwala mzere malinga ndi kusintha msika.

Kukhudzidwa ndi zinthu monga COVID-19 komanso kusakhazikika kwachuma, kufunikira kwamagetsi ogula monga mawotchi ndi mapiritsi kudzakhala kwaulesi mu 2022, ndipo kufunikira kwa ma lasers othamanga kwambiri mu PCB (board board yosindikizidwa), mapanelo owonetsera ndi ma LED atsika. Ndi magawo ozungulira okha ndi ma chip omwe adayendetsedwa, ndipo makina olondola kwambiri a laser akumana ndi zovuta zakukula.

Njira yotulukira ma lasers othamanga kwambiri ndikuwonjezera mphamvu ndikupanga zochitika zambiri zogwiritsira ntchito. Ma picoseconds mazanamazana adzakhala okhazikika mtsogolomo. Kuchulukitsa kubwereza komanso ma lasers amphamvu amphamvu amathandizira kuti pakhale kuthekera kokulirapo, monga kudula ndi kubowola magalasi mpaka 8 mm wandiweyani. Laser ya UV picosecond ilibe kupsinjika kwamatenthedwe ndipo ndiyoyenera kukonza zida zovutirapo, monga kudula ma stents ndi zinthu zina zachipatala zomwe zimakhala zovuta kwambiri.

Pamsonkhano wazinthu zamagetsi ndi kupanga, zakuthambo, zamoyo, zowotchera semiconductor ndi mafakitale ena, padzakhala kuchuluka kwazinthu zofunikira pakukonza magawo, ndipo kusalumikizana kwa laser kudzakhala chisankho chabwino kwambiri. Pamene chilengedwe chachuma chikuyamba, kugwiritsa ntchito ma lasers a ultrafast kudzabwereranso pakukula kwakukulu.
