Cov txheej txheem ntawm laser txiav hlau
Nrog rau laser txiav tshuab, laser txiav yog ntau thiab ntau lug siv thiab tsim cov ntaub ntawv kuj nce. Txawm li cas los xij, cov khoom sib txawv muaj cov khoom sib txawv, yog li cov teeb meem xav tau kev saib xyuas ntawm laser txiav kuj txawv. Golden laser nyob rau hauv laser txiav kev lag luam rau ntau xyoo, tom qab ib tug ntev lub sij hawm ntawm kev xyaum tsis tu ncua summed rau txawv cov ntaub ntawv laser txiav txiav txim siab.
Cov qauv hlau
Cov khoom siv nrog oxygen txiav tuaj yeem tau txais txiaj ntsig zoo dua. Thaum siv cov pa oxygen raws li cov txheej txheem roj, qhov txiav ntug yuav raug oxidized me ntsis. Daim ntawv tuab ntawm 4 hli, nitrogen tuaj yeem siv los ua cov txheej txheem roj siab txiav. Hauv qhov no, qhov txiav ntug tsis oxidized. Thickness ntawm 10mm los yog ntau tshaj ntawm lub phaj, lub laser thiab kev siv cov phaj tshwj xeeb rau saum npoo ntawm lub workpiece thaum lub sij hawm machining oiled yuav tau txais ib tug zoo nyhuv.
Stainless hlau
Txiav ntawm stainless hlau yuav tsum tau siv cov pa oxygen. Nyob rau hauv cov ntaub ntawv ntawm ntug ntawm oxidation tsis muaj teeb meem, kev siv cov nitrogen kom tau ib tug tsis-oxidizing thiab tsis muaj burr ntug, tsis tas yuav tsum tau rov ua dua. Txheej cov phaj perforated zaj duab xis yuav tau txais txiaj ntsig zoo dua, tsis tas yuav txo qhov kev ua haujlwm zoo.
Aluminium
Txawm hais tias muaj kev cuam tshuam siab thiab thermal conductivity, aluminium tsawg dua 6mm thickness tuaj yeem txiav. Nws nyob ntawm hom alloy thiab laser muaj peev xwm. Thaum txiav cov pa oxygen, qhov txiav nto ntxhib thiab tawv. Nrog nitrogen, qhov txiav nto yog du. Ntshiab aluminium txiav yog nyuaj heev vim nws siab purity. Tsuas yog ntsia rau ntawm qhov system ntawm "reflection-absorption", lub tshuab tuaj yeem txiav aluminium. Txwv tsis pub nws yuav rhuav tshem cov khoom siv kho qhov muag pom.
Titanium
Titanium ntawv nrog argon roj thiab nitrogen raws li cov txheej txheem roj los txiav. Lwm qhov kev ntsuas tuaj yeem xa mus rau nickel-chromium hlau.
Tooj thiab tooj dag
Ob qho khoom siv muaj qhov cuam tshuam siab thiab zoo thermal conductivity. Thickness tsawg dua 1 hli tuaj yeem siv nitrogen txiav tooj dag, tooj liab thickness tsawg dua 2 hli tuaj yeem txiav, cov txheej txheem roj yuav tsum yog oxygen. Muaj tsuas yog ntsia rau ntawm lub system, "reflection-absorption" txhais tau tias thaum lawv tuaj yeem txiav tooj liab thiab tooj dag. Txwv tsis pub nws yuav rhuav tshem cov khoom siv kho qhov muag pom.
Cov khoom siv hluavtaws
Txiav cov khoom siv hluavtaws kom nco ntsoov thaum txiav emissions ntawm cov khoom txaus ntshai thiab muaj peev xwm txaus ntshai. Cov khoom siv hluavtaws tuaj yeem ua tiav: thermoplastics, cov khoom siv thermosetting, thiab cov roj hmab hluavtaws.
Organics
Nyob rau hauv tag nrho cov kab mob muaj nyob rau hauv ob qho tib si txiav txoj kev pheej hmoo ntawm hluav taws (nrog nitrogen raws li cov txheej txheem roj, compressed cua kuj yuav siv tau raws li ib tug txheej txheem roj). Ntoo, tawv, cardboard thiab ntawv tuaj yeem txiav nrog laser, txiav ntug tuaj yeem scorch (xim av).
Los ntawm cov ntaub ntawv sib txawv, cov kev xav tau sib txawv, siv cov khoom siv hluav taws xob tsim nyog tshaj plaws thiab kev siv tshuab, yuav tau txais txiaj ntsig zoo tshaj plaws.
