Itekhnoloji yokugaya ibhodi yesekethe umatshini wokugaya i-CNC ibandakanya ukukhetha isalathiso sesixhobo, indlela yembuyekezo, indlela yokumisa, ulwakhiwo lwesakhelo, kunye nendawo yokusika, ezo ziyimiba ebalulekileyo yokuqinisekisa ukuchaneka kwenkqubo yokugaya. . Oku kulandelayo yi Ibhodi PCB inkqubo yokusila ishwankathelwe nguJie Duobang pcb ubuchule bolawulo oluchanekileyo kunye neendlela.

Indlela yokusika kunye nendlela yembuyekezo:

Xa i-milling cutter inqumla kwi-plate, enye yobuso obuza kunqunyulwa isoloko ijongene nomda wokusika we-milling cutter, kwaye elinye icala lihlala lijongene nomgca wokusika we-milling cutter. Eyangaphambili inomphezulu ogudileyo oza kucutshungulwa kunye nokuchaneka okuphezulu. I-spindle isoloko ijikeleza ngokwewotshi. Ke ngoko, nokuba ngumatshini wokungqusha we-CNC onentshukumo esisigxina yokusonta okanye intshukumo esisigxina yokusonta, xa usila i-contour yangaphandle yebhodi eprintiweyo, isixhobo kufuneka sihanjiswe ngokuchasene newotshi.

Oku ngokuqhelekileyo kubizwa ngokuba yi-up milling. Ukunyuka kokugaya kusetyenziswa xa ukugaya isakhelo okanye i-slot ngaphakathi kwebhodi yesekethe. Imbuyekezo yokusila kuxa isixhobo somatshini sifakela ngokuzenzekelayo ixabiso elibekiweyo ngexesha lokusila, ukuze umsiki wokusila asuse ngokuzenzekelayo isiqingatha sedayamitha yokusila ukusuka kumbindi womgca wokusila, oko kukuthi, umgama weradiyasi, ukuze ubume ukugaya kusetwa yinkqubo mayingqinelane. Ngelo xesha, ukuba isixhobo somatshini sinomsebenzi wembuyekezo, kufuneka ubeke ingqalelo kwisalathiso sembuyekezo kunye nomyalelo weprogram. Ukuba umyalelo wembuyekezo usetyenziswa ngendlela engafanelekanga, imilo yebhodi yesekethe iya kuba ngaphezulu okanye ngaphantsi ngokulingana nobude kunye nobubanzi be-milling cutter ububanzi.

Indlela yokuma kunye nendawo yokusika:

Kukho iindidi ezimbini zeendlela zokubeka; enye kukumi kwangaphakathi, kwaye enye kukumi ngaphandle. Ukuma nako kubaluleke kakhulu kwiingcibi. Ngokuqhelekileyo, isicwangciso sokumisa kufuneka sinqunywe ngexesha lokuveliswa kwangaphambili kwebhodi yesekethe.

Ukuma kwangaphakathi yindlela yehlabathi jikelele. Into ebizwa ngokuba yi-internal positioning kukukhetha imingxuma yokunyuka, imingxuma yeplagi okanye enye imingxuma engeyiyo i-metalized kwibhodi eprintiweyo njengemingxuma yokubeka. Indawo ehambelanayo yemingxuma kufuneka ibe kwi-diagonal kwaye ukhethe umngxuma omkhulu wedayamitha kangangoko kunokwenzeka. Imingxuma eyenziwe ngesinyithi ayinakusetyenziswa. Ngenxa yokuba umahluko kubunzima bomgangatho wokutya emngxunyeni uya kuchaphazela ukuhambelana komngxuma wokumisa owukhethayo, kwaye kwangaxeshanye, kulula ukubangela ukuba umaleko weplating emngxunyeni wonakaliswe. xa ibhodi ithathwa. Ngaphantsi komqathango wokuqinisekisa ukubekwa kwebhodi eprintiweyo, inani lezikhonkwane liya kuba lincinci Ingcono.

Ngokuqhelekileyo, ibhodi encinci isebenzisa izikhonkwane ezi-2 kwaye ibhodi enkulu isebenzisa izikhonkwane ezi-3. Izibonelelo kukubekwa okuchanekileyo, ukuguqulwa okuncinci kobume bebhodi, ukuchaneka okuphezulu, ukumila okulungileyo, kunye nesantya sokugaya ngokukhawuleza. Ukungalungi: Kukho iintlobo ezininzi zemingxuma ebhodini efunekayo ukulungiselela izikhonkwane zobubanzi obuhlukeneyo. Ukuba akukho mingxunya yokubeka ekhoyo ebhodini, kunzima ukuxoxa nomthengi ukongeza imingxuma yokubeka ebhodini ngexesha lemveliso yokuqala. Ngelo xesha, ulawulo oluhlukeneyo lweetemplates zokugaya uhlobo ngalunye lwebhodi luyinkathazo kwaye luyabiza.

Ukuma kwangaphandle yenye indlela yokumisa, esebenzisa imingxuma yokumisa ngaphandle kwebhodi njengemingxuma yokumisa ipleyiti yokusila. Inzuzo yayo kukuba kulula ukuyilawula. Ukuba iinkcukacha zangaphambili zemveliso zilungile, kukho ngokubanzi malunga ne-15 iintlobo zetemplates zokugaya. Ngenxa yokusetyenziswa kokumiswa kwangaphandle, ibhodi ayinakuxutywa kwaye inqunywe ngexesha elinye, ngaphandle koko ibhodi yesekethe kulula kakhulu ukuyonakalisa, ngakumbi i-jigsaw, kuba i-milling cutter kunye nomqokeleli wothuli uya kukhupha ibhodi, ebangela ukuba ibhodi yesekethe. ukuba yonakaliswe kwaye i-milling cutter yaphuka.

Ukusebenzisa indlela yokugaya i-segmented ukushiya amanqaku adibeneyo, okokuqala ukugaya ipleyiti. Xa ukugaya kugqityiwe, inkqubo iyayeka kwaye ipleyiti igxininiswe ngeteyiphu. Icandelo lesibini leprogram liyenziwa, kwaye indawo edibeneyo ikhutshwe kunye ne-3mm ukuya kwi-4mm drill bit. Inzuzo yayo kukuba ithemplate ayibizi kwaye kulula ukuyilawula. Iyakwazi ukugaya zonke iibhodi zesekethe ngaphandle kwemingxuma yokufaka kunye nokubeka imingxuma ebhodini. Kuyafaneleka ukuba iingcibi ezincinci zilawule. Ngokukodwa, ukuveliswa kwe-CAM kunye nabanye abasebenzi bokuqala bemveliso bangenziwa lula kwaye i-substrate inokulungiswa ngexesha elifanayo. Izinga lokusetyenziswa. Ukungalungi kukuba ngenxa yokusetyenziswa kwee-drills, ibhodi yesekethe inamanqaku angama-2-3 aphakanyisiweyo angekho mhle, anokuthi ahlangabezane neemfuno zabathengi, ixesha lokugaya lide, kwaye ukuqina kwabasebenzi kukhulu kancinci.

Isakhelo kunye nendawo yokusika:

Imveliso yesakhelo yeyemveliso yokuqala yebhodi yesekethe. Uyilo lwesakhelo aluchaphazeli nje ukufana kwe-electroplating, kodwa luchaphazela ukugaya. Ukuba uyilo alulunganga, isakhelo kulula ukukhubaza okanye ezinye iincinci ezincinci ziveliswa ngexesha lokugaya. Iziqwenga ezincinci, i-scraps eveliswayo iya kuthintela ityhubhu ye-vacuum okanye iphule i-high-speed-roating milling cutter. I-deformation yesakhelo, ngakumbi xa ibeka ipleyiti yokugaya ngaphandle, ibangela ukuba ipleyiti egqityiweyo iguqulwe. Ukongezelela, ukukhethwa kwendawo yokusika kunye nokulandelelana kokucubungula kunokwenza isakhelo Gcina ubuninzi obuphezulu kunye nesantya esikhawulezayo. Ukuba ukhetho alulunganga, isakhelo sinokukhubazeka ngokulula kwaye ibhodi eprintiweyo iyachithwa.

Iiparamitha zenkqubo yokugaya:

Sebenzisa i-cemented carbide milling cutter ukugaya imilo yebhodi eprintiweyo. Isantya sokusika i-cutter yokugaya ngokuqhelekileyo yi-180-270m / min. Ifomula yokubala imi ngolu hlobo lulandelayo (kwireferensi kuphela):

S=pdn/1000 (m/min)

Indawo: PI (3.1415927)

d: Ububanzi bomsiki wokusila, mm
