Laser txiav ntawm stainless hlau
Thaum laser txiav stainless hlau cov ntaub ntawv, yog tias cov kev cai rau ntug oxidation tsis nruj heev, oxygen tuaj yeem siv los ua cov roj ua rau kev txiav. Yog tias nws yuav tsum tau txais cov npoo tsis muaj oxidation thiab burr, ces nitrogen yuav tsum tau siv los ua cov pa roj rau kev txiav, kom cov npoo tau txais tsis xav tau lwm yam kev kho mob. Yog hais tias lub laser yog siv rau drilling, ib tug roj zaj duab xis yuav coated nyob rau saum npoo ntawm stainless hlau phaj, uas yuav tau ib tug zoo perforation nyhuv yam tsis tau txo cov kev ua tau zoo.
Laser txiav ntawm structural steel
Thaum laser txiav cov khoom siv hlau, cov pa oxygen tuaj yeem raug xaiv los ua cov roj ua kom tau txais kev txiav zoo dua, tab sis nws kuj ntsib teeb meem ntawm me ntsis ntug oxidation. Tshwj xeeb tshaj yog rau daim hlau nrog lub thickness ntawm ntau tshaj 4 hli, lub zog ntawm oxidation yog hnyav dua. Yog li ntawd, nws yog qhov zoo tshaj plaws los siv nitrogen raws li cov roj ua rau kev kub siab txiav ntawm daim hlau nrog lub thickness ntawm ntau tshaj 4 hli. Ua li no, qhov teeb meem ntawm ntug oxidation yuav tsis tshwm sim. Rau cov txheej txheem steel daim hlau nrog lub thickness ntawm ntau tshaj 10 hli, siv cov phaj tshwj xeeb rau lasers thiab txheej txheej roj zaj duab xis rau saum npoo ntawm lub workpiece thaum lub sij hawm ua tau zoo dua.
Aluminium laser txiav
Vim tias txhuas muaj kev cuam tshuam siab thiab thermal conductivity, nws tsis tsim nyog siv laser txiav rau txhuas daim hlau nrog loj tuab. Rau cov ntaub ntawv txhuas nrog lub thickness tsawg dua 6 hli, laser txiav yuav siv tau nyob ntawm seb hom aluminium alloy thiab laser muaj peev xwm. Yog tias cov pa oxygen siv los ua cov pa roj, nws yooj yim ua rau tawv thiab tawv. Ib tug du txiav nto tuaj yeem tau los ntawm kev siv nitrogen. Cov khoom siv ntshiab aluminium yog qhov nyuaj heev los txiav vim tias nws cov purity siab thiab muaj kev cuam tshuam siab. Tsuas yog thaum lub cuab yeej "reflection absorption" tau teeb tsa rau ntawm lub kaw lus tuaj yeem txiav cov txhuas ntshiab, txwv tsis pub qhov kev xav yuav rhuav tshem cov khoom siv kho qhov muag ntawm lub laser.
Titanium laser txiav
Nws tsis yog nyuaj rau txiav titanium. Tsuas muaj ib yam uas yuav tsum tau them sai sai rau, uas yog, siv argon thiab nitrogen ua cov roj rau kev txiav.
Laser txiav ntawm tooj liab thiab tooj dag
Ob qho tib si tooj liab thiab tooj dag muaj qhov cuam tshuam siab thiab thermal conductivity zoo heev, yog li lawv kuj koom rau hauv qeb ntawm cov ntaub ntawv uas nyuaj rau txiav los ntawm laser. Brass nrog thickness tsawg dua 1 hli tuaj yeem txiav nrog nitrogen. Brass nrog thickness ntawm 1 hli thiab 2 hli yuav tsum tau txiav nrog oxygen. Brass nrog thickness ntau tshaj 2 hli tsis tuaj yeem txiav nrog laser. Tsis tas li ntawd, zoo ib yam li cov ntshiab txhuas, thaum txiav tooj liab thiab tooj dag, "reflection absorption" ntaus ntawv yuav tsum tau nruab rau hauv lub cev, txwv tsis pub qhov kev xav yuav ua rau cov khoom siv kho qhov muag puas.
Cov khoom siv hluavtaws thiab cov organics
Ntxiv rau cov khoom siv hlau, cov khoom siv hluavtaws thiab cov khoom siv organic kuj yog cov ntaub ntawv uas feem ntau raug txiav los ntawm laser, xws li cov khoom siv thermoplastic, cov khoom siv thermosetting, cov khoom siv roj hmab, ntoo, tawv, cardboard thiab lwm yam. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias kev phom sij ntawm kev sib tsoo yog yooj yim tshwm sim thaum txiav, thiab lwm yam emissions kuj muaj qee yam toxicity. Cov yam tsis zoo no yuav tsum tau tiv thaiv. Thaum cov organic teeb meem raug txiav los ntawm laser, ntug ntawm cov khoom yuav xim av vim scorching.
