Nrog qhov nce ntawm kev thov rau siab-precision machining, muaj feem xyuam precision tshuab kev lag luam kuj tau tsim kho sai, thiab precision fiber ntau laser txiav tshuab hlau kuj tau nce ntau thiab ntau qhov kev lees paub hauv kev ua lag luam.
Cov khoom txiav ntawm cov fiber ntau laser txiav tshuab hlau ua tshuab yog feem ntau nyias daim hlau. Qhov ua tiav raug yog qhov siab, qhov nrawm yog nrawm, thiab qhov phais phais kuj du thiab tiaj. Feem ntau, tsis muaj kev ua tom ntej ntxiv yuav tsum ua; cov txiav kub cuam tshuam cheeb tsam yog me me, lub phaj deformation me me; qhov rov ua tau zoo, thiab cov khoom siv tsis raug puas ntsoog. Nyob rau tam sim no, precision yog tsuas yog siv nyob rau hauv PCB board txiav, microelectronic Circuit Court template kev txiav, qhov muag tsom kev lag luam, kev ua cov hniav nyiaj hniav kub thiab lwm yam lag luam.
Laser precision machining muaj cov yam ntxwv zoo kawg li hauv qab no:
(1) Cov khoom siv dav: Cov ntau yam ntawm cov khoom ua haujlwm tuaj yeem ua tiav los ntawm precision lasers yog qhov dav heev, suav nrog yuav luag txhua yam khoom siv hlau thiab cov khoom siv tsis yog hlau; tsim nyog rau kev lag luam sintering, drilling, cim, txiav, vuam, hloov kho saum npoo thiab tshuaj vapor tso ntawm cov ntaub ntawv Tos. Kev siv hluav taws xob tsuas tuaj yeem ua cov txheej txheem khoom sib ze. Photochemical kev tsuas yog tsim nyog rau cov ntaub ntawv corrosive. Kev ua ntshav yog qhov nyuaj rau kev ua cov txheej txheem siab melting point cov ntaub ntawv.
(2) Qhov tseeb thiab ceevfaj heev: Qhov loj me uas pom lub nqaj nplaim laser tuaj yeem tsom tau yog tsawg heev. Muaj ob peb yam uas cuam tshuam rau qhov zoo ntawm precision laser ua, thiab kev ua kom raug yog qhov siab, uas feem ntau zoo dua li lwm cov kev ua ib txwm ua.
(3) Kev kub ceev thiab nrawm: Los ntawm qhov pom ntawm kev ua lub voj voog, lub tshuab hluav taws xob ntawm EDM yuav tsum muaj qhov siab, qhov ploj loj, thiab kev ua lub sijhawm ntev; kev tsim ua haujlwm ntawm cathode pwm ntawm lub tshuab machining kab noj hniav thiab lub npoo ntawm cov tshuab hluav taws xob muaj qhov loj, thiab kev voj voog raug kuj yog ntev heev; photochemical kev ua yog qhov nyuaj; thiab precision laser ua haujlwm yog qhov yooj yim hauv kev ua haujlwm, txoj kab txiav dav dav yog yooj yim los kho, thiab tuaj yeem nrawm thiab txiav raws cov qauv tsim los ntawm lub khoos phis tawm. Txoj kev khiav ceev yog ceev, thiab lub voj voog ua yog luv dua lwm txoj kev.
(4) Muaj kev nyab xeeb thiab txhim khu kev qha: raws li qhov tseeb laser txiav thev naus laus zis rau kev ua haujlwm tsis sib cuag, nws yuav tsis ua rau cov khoom puas vim lub tshuab extrusion lossis tshuab kev ntxhov siab; piv nrog EDM, plasma arc ua, nws cov tshav kub cuam tshuam cheeb tsam thiab deformation yog qhov tsawg heev, yog li Muaj peev xwm ua tau qhov chaw me me.
(5) Tus nqi qis: Rau cov kev pab cuam me me ua, precision laser txiav tsis txwv los ntawm tus naj npawb ntawm kev ua, nws kuj pheej yig dua. Rau kev ua cov khoom lag luam loj, cov pwm tsim cov nqi ntawm cov khoom lag luam loj heev, cov txheej txheem laser tsis xav tau kev tsim pwm lag luam, thiab laser ua tiav tag nrho zam cov sags tsim thaum lub punching thiab shearing ntawm cov ntaub ntawv, thaum txo cov khoom lag luam ntau lawm ntawm kev lag luam Txhim kho qib qib ntawm cov khoom.
(6) Kev txiav cov kab yog me: qhov txiav txiav ntawm cov kab txiav laser feem ntau yog 0.1-0.2mm.
(7) Qhov txiav saum npoo yog qhov ncaj: qhov laser txiav saum npoo tsis muaj burrs.
(8) Cov cua sov deformation me: Lub tshuab txiav laser muaj qhov sib dhos zoo, kev nrawm nrawm, thiab lub zog muaj zog, yog li cov cua sov hloov mus rau cov khoom yuav raug txiav yog qhov me me, thiab deformation ntawm cov khoom kuj tseem me me.
(9) Kev txuag cov khoom: laser ua kev hloov kho lub koos pij tawj, uas tuaj yeem tsim cov khoom ntawm cov duab sib txawv los ua kom ua tiav kev siv cov khoom thiab txo nqi ntawm cov khoom lag luam.
(10) Lub voj voog kev loj hlob ntawm cov khoom tshiab yog luv: thaum cov khoom kos duab tsim, kev ua cov laser tuaj yeem nqa tawm tam sim, thiab cov khoom lag luam tiag ntawm cov khoom tshiab tuaj yeem tau txais hauv lub sijhawm luv.
Feem ntau, laser precision machining tshuab muaj ntau qhov zoo dua li cov kev ib txwm ua hauv kev, thiab nws daim ntawv thov kev cia siab yog qhov dav heev.
