Kusankha Kuyang'ana Kwabwino/Koipa Panthawi Yodula Laser

Podula pogwiritsa ntchito laser, kusankha pakati pa defocus yabwino (kuganizira bwino) ndi defocus yoyipa (kuganizira molakwika) kumadalira kwambiri mtundu wa zinthu, makulidwe a mbale, ndi zofunikira pa ndondomeko. Pansipa pali chitsogozo chomveka bwino komanso chosavuta popanga zisankho.

Mfundo Zazikulu

Choyang'ana kwambiri (zero defocus):Mphamvu zimakhala zochulukirapo, zomwe zimapangitsa kuti kerf yodulidwa ikhale yopapatiza kwambiri. Yoyenera kudula mapepala opyapyala molondola kwambiri komanso mwachangu kwambiri, imaika patsogolo "kukonzanso."

Kuyang'ana kolakwika (kuchotsa kulunjika kolakwika):Mphamvu imafalikira kwambiri, zomwe zimapangitsa kuti msoko wodulidwa ukhale wokulirapo. Yoyenera mbale zokhuthala, imathandizira kuchotsa zinyalala ndikuteteza lenzi, makamaka "mphamvu yolowera ndi khalidwe."

Kodi ndi liti pamene muyenera kugwiritsa ntchito njira yodulira zinthu pogwiritsa ntchito in-focus (zero defocus)?

Zochitika zogwiritsidwa ntchito: Kudula mbale zopyapyala (nthawi zambiri zosakwana 3 mm), makamaka m'magwiritsidwe ntchito omwe ali ndi zofunikira kwambiri pakuchita bwino komanso mwachangu.

1. Kudula mbale zoonda mwanzeru:

• Zitsanzo za zinthu: pepala lopyapyala la chitsulo cha kaboni, pepala losapanga dzimbiri, mkuwa, pepala la aluminiyamu, ndi zina zotero.
• Chifukwa: Mapepala opyapyala amapanga slag yochepa yosungunuka, kotero sikofunikira kuti muchotsedwe. Kugwiritsa ntchito njira yabwino yowunikira kungathandize kupeza malo ochepa kwambiri komanso mphamvu zambiri, kuti muchepetse liwiro lodula kwambiri komanso kuti muchepetse gawo losalala komanso lolunjika.

2. Kulondola kwambiri komanso mpata wopapatiza:

• Zitsanzo zogwiritsira ntchito: zigawo zolondola, zida zamagetsi, zodzikongoletsera, mapatani opanda kanthu, ndi zina zotero.
• Chifukwa: Kerf yomwe imapangidwa ndi positive focus ndi yopapatiza kwambiri, yokhala ndi kutayika kochepa kwa zinthu, ndipo imatha kudula mizere yopyapyala kwambiri ndi ngodya zakuthwa kuti isasungunuke kwambiri.

3. Kufunafuna liwiro lodulira:

• Mukadula mbale zopyapyala, mphamvu zambiri mu positive focus mode zimatanthauza kuti liwiro la chakudya lingagwiritsidwe ntchito mofulumira, motero kumawonjezera mphamvu yopangira.

Chidule:Podula zinthu zoonda, ndipo cholinga chachikulu ndi liwiro, kulondola komanso malo opapatiza, chinthu chofunikira kwambiri ndi kusankha malo abwino.

Kodi ndi liti pamene muyenera kudula ndi focus yoyipa (negative defocus)?

Momwe mungagwiritsire ntchito: kudula mbale yapakatikati ndi yokhuthala (nthawi zambiri ≥ 3mm), makamaka pamene pakufunika kutulutsa bwino slag ndi mtundu wa gawo.

1. Kudula mbale:

• Zitsanzo za zipangizo: chitsulo cha kaboni, chitsulo chosapanga dzimbiri, mbale ya aluminiyamu, ndi zina zotero pamwamba pa 3mm.
• Chifukwa: Ma mbale okhuthala amapanga chitsulo chosungunuka kwambiri (slag). Coke yoyipa imapereka mpata waukulu, zomwe zimathandiza mpweya wothandizira (monga mpweya kapena nayitrogeni) kuti utulutse bwino slag kuchokera pansi, zomwe zimalepheretsa slag kupachikidwa ndi kudula.

2. Mukufuna gawo lapamwamba kwambiri:

• Chifukwa: Pa mbale zokhuthala, ngati cholinga chabwino chikugwiritsidwa ntchito, mphamvu imayikidwa pamwamba, zomwe zimapangitsa kuti gawo lapamwamba likhale losalala ndipo gawo la pansi likhale lolimba. Cholinga choipa chimapangitsa kuti kugawa mphamvu kukhale kofanana kwambiri ndi makulidwe a mbaleyo, kuti pakhale malo odulira okhazikika komanso osalala kuyambira pamwamba mpaka pansi.

3. Tetezani galasi loyang'ana:

• Chifukwa: Mukadula mbale zokhuthala, makamaka mbale zachitsulo zokhala ndi dzimbiri kapena zinthu zomwe zimakhala ndi kuphulika kwakukulu, malo owunikira olakwika amachititsa kuti kuyang'ana kukhale mkati mwa workpiece, zomwe zimawonjezera mtunda kuchokera pamwamba pa workpiece kupita ku galasi loyang'ana ndikuchepetsa kuphulika kwachitsulo. Chiwopsezo chogunda ndi kuwononga galasi loyang'ana lokwera mtengo.

4. Njira yeniyeni (monga kudula kwa nayitrogeni ndi aloyi ya aluminiyamu):

• Chifukwa: Nayitrogeni nthawi zambiri imagwiritsidwa ntchito ngati mpweya wothandizira podula zitsulo za aluminiyamu. Mpweya wothamanga kwambiri umafunika kuti aluminiyamu yosungunuka ituluke. Chophimba chachikulu chomwe chimaperekedwa ndi coke yoyipa ndi chofunikira kwambiri pakuyenda bwino kwa nayitrogeni wothamanga kwambiri komanso kutulutsa slag, ndipo ndicho chofunikira kwambiri kuti chodulacho chisakhale ndi ma burrs komanso kuwala kwa pamwamba.

Chidule:Podula zinthu zokhuthala, cholinga chachikulu ndikuonetsetsa kuti zidula, kuchepetsa matope, kupeza malo olumikizirana komanso kuteteza zida, coke yoyipa ndiyo yabwino kwambiri.

Tchati cha Kuyenda kwa Zisankho Mwachangu

Malangizo ogwiritsidwa ntchito

1. Kuchuluka koyenera kwa defocus kumayesedwa:Malamulo omwe ali pamwambawa ndi malangizo wamba. Kuchuluka koyenera kwa defocus pa chida china cha makina ndi zinthu kuyenera kutsimikiziridwa ndi kuyesa kwa njira. Wogwiritsa ntchitoyo adzachita "slit test" kuti apeze magawo abwino kwambiri powona mtundu wa gawolo ndi slag yopachikika.

2. Kukhazikitsa cholinga choipa:Kuchuluka kwa kulunjika kolakwika nthawi zambiri sikutanthauza kuti ndi chinthu chokhazikika, koma ndi mtundu wogwirizana ndi makulidwe a mbale. Poyambira poyambira ndi 1/4 mpaka 1/3 ya makulidwe a pepala. Mwachitsanzo, kudula 12mm ya chitsulo cha kaboni, kuyesako kungayambitsidwe kuyambira -2mm mpaka -3mm.

3. Zipangizo ndizofunikira kwambiri:Zipangizo zosiyanasiyana zimakhala ndi mphamvu yosiyana yowunikira. Mwachitsanzo, chitsulo chosapanga dzimbiri chimakhala chosavuta kuwunikira kuposa chitsulo cha kaboni.
