Ubuchwepheshe bokugaya umshini wokugaya we-CNC webhodi lesifunda buhlanganisa ukukhetha isiqondiso sethuluzi, indlela yesinxephezelo, indlela yokumisa, ukwakheka kohlaka, kanye nendawo yokusika, okuyizo zonke izici ezibalulekile zokuqinisekisa ukunemba kwenqubo yokugaya. . Okulandelayo yi- PCB ibhodi inqubo yokugaya ifinyezwe yi-Jie Duobang pcb amasu okulawula ukunemba nezindlela.

Indlela yokusika nendlela yesinxephezelo:

Lapho umsiki wokugaya esika epuletini, obunye bobuso obuzosikwa buhlala bubheke onqenqemeni lokusika lomshini wokugaya, kanti olunye uhlangothi luhlala lubheke onqenqemeni lokusika lomshini wokugaya. Eyangaphambili inobuso obushelelezi okufanele bucutshungulwe kanye nokunemba okuphezulu kobukhulu. I-spindle ihlale izungeza ngokwewashi. Ngakho-ke, noma ngabe umshini wokugaya we-CNC onokunyakaza okuphothayo okungaguquki noma ukunyakaza okugxilile kokuphotha, lapho ugaywa i-contour yangaphandle yebhodi eliphrintiwe, ithuluzi kufanele lihanjiswe ngokuphambene newashi.

Lokhu ngokuvamile kubizwa ngokuthi i-up milling. Ukugaya i-climbing kusetshenziswa lapho kugaya ifreyimu noma i-slot ngaphakathi kwebhodi lesifunda. Isinxephezelo sokugaya yilapho ithuluzi lomshini lifaka ngokuzenzakalelayo inani elibekiwe ngesikhathi sokugaya, ukuze umsiki wokugaya asuse ngokuzenzakalelayo uhhafu wesethi yobubanzi bokusika umshini wokugaya ukusuka phakathi nendawo yomugqa wokugaya, okungukuthi, ibanga lerediyasi, ukuze ukuma milling isethwe uhlelo kube ngokuvumelana. Ngesikhathi esifanayo, uma ithuluzi lomshini linomsebenzi wokunxeshezelwa, kufanele unake isiqondiso sesinxephezelo kanye nomyalo wohlelo. Uma umyalo wesinxephezelo usetshenziswa ngokungalungile, ukuma kwebhodi lesifunda kuzolingana noma ngaphansi nobude nobubanzi bobubanzi be-milling cutter.

Indlela yokuma nendawo yokusika:

Kunezinhlobo ezimbili zezindlela zokubeka; enye iwukuma kwangaphakathi, kanti enye ukuma kwangaphandle. Ukuma nakho kubaluleke kakhulu kubadwebi. Ngokuvamile, uhlelo lokuma kufanele lunqunywe ngesikhathi sokukhiqizwa kwangaphambili kwebhodi lesifunda.

Ukuma kwangaphakathi kuyindlela yendawo yonke. Okubizwa ngokuthi ukuma kwangaphakathi ukukhetha izimbobo ezifakwayo, izimbobo zokuxhuma noma ezinye izimbobo ezingenasici ebhodini eliphrintiwe njengezimbobo zokubeka. Ukuma okuhlobene kwezimbobo kufanele kube ku-diagonal futhi kukhethwe imbobo enkulu yobubanzi ngangokunokwenzeka. Izimbobo ezenziwe ngensimbi azikwazi ukusetshenziswa. Ngoba umehluko ebukhulu besendlalelo se-plating emgodini kuzothinta ukuvumelana kwembobo yokubeka oyikhethayo, futhi ngasikhathi sinye, kulula ukubangela ungqimba lokucwenga emgodini kanye nonqenqema lwembobo ukuthi lonakaliswe. lapho ibhodi lithathwa. Ngaphansi kombandela wokuqinisekisa ukuma kwebhodi eliphrintiwe, inani lezikhonkwane lizoba lincane Okungcono.

Ngokuvamile, ibhodi elincane lisebenzisa izikhonkwane ezi-2 kanti ibhodi elikhulu lisebenzisa izikhonkwane ezi-3. Izinzuzo ukuma okunembile, ukuwohloka okuncane komumo webhodi, ukunemba okuphezulu, ukuma okuhle, kanye nesivinini sokugaya esisheshayo. Ukungalungi: Kunezinhlobo eziningi zezimbobo ebhodini ezidinga ukulungisa izikhonkwane zama-diameter ahlukahlukene. Uma zingekho izimbobo zokubeka ebhodini, kuba nzima kakhulu ukuxoxa nekhasimende ukuze wengeze izimbobo zokubeka ebhodini ngesikhathi sokukhiqizwa kokuqala. Ngesikhathi esifanayo, ukuphathwa okuhlukene kwezifanekiso zokugaya zohlobo ngalunye lwebhodi kuyinkinga futhi kuyabiza.

Ukuma kwangaphandle kungenye indlela yokubeka, esebenzisa izimbobo zokubeka ngaphandle kwebhodi njengezimbobo zokubeka ipuleti lokugaya. Inzuzo yayo ukuthi kulula ukuyiphatha. Uma ukucaciswa kwangaphambili kokukhiqiza kuhle, ngokuvamile kunezinhlobo ezingu-15 zezifanekiso zokugaya. Ngenxa yokusetshenziswa kokuma kwangaphandle, ibhodi alikwazi ukugaywa futhi linqunywe ngesikhathi esisodwa, ngaphandle kwalokho ibhodi lesifunda lilula kakhulu ukulimaza, ikakhulukazi i-jigsaw, ngoba i-milling cutter kanye nomqoqi wothuli uzokhipha ibhodi, okubangela ibhodi lesifunda. ukonakala kanye nesigayo sokugaya siphuke.

Usebenzisa indlela yokugaya okuhlukene ukuze ushiye amaphuzu ahlangene, qala ugaye ipuleti. Lapho ukugaya sekuqediwe, uhlelo luyama bese ipuleti lilungiswa nge-tape. Isigaba sesibili sohlelo senziwa, futhi iphuzu elihlangene likhishwa nge-drill bit 3mm kuya ku-4mm. Inzuzo yayo ukuthi ithempulethi ayibizi futhi kulula ukuyiphatha. Ingakwazi ukugaya wonke amabhodi wesekethe ngaphandle kwezimbobo ezifakwayo kanye nezimbobo zokubeka ebhodini. Ilungele izingcweti ezincane ukuphatha. Ikakhulukazi, ukukhiqizwa kwe-CAM nezinye izisebenzi zokukhiqiza zakuqala kungenziwa lula futhi i-substrate ingenziwa kahle ngesikhathi esifanayo. Izinga lokusetshenziswa. Okubi ukuthi ngenxa yokusetshenziswa kwama-drill, ibhodi lesifunda linamaphuzu aphakanyisiwe okungenani angu-2-3 angemahle, okungenzeka angahlangabezani nezidingo zamakhasimende, isikhathi sokugaya side, futhi umfutho wabasebenzi ukhulu kancane.

Uhlaka nendawo yokusika:

Ukukhiqizwa kohlaka kungokwasekuqaleni kokukhiqizwa kwebhodi lesifunda. Ukwakhiwa kohlaka akuthinti nje kuphela ukufana kwe-electroplating, kodwa futhi kuthinta ukugaya. Uma umklamo ungemuhle, ifreyimu kulula ukukhubaza noma ezinye izingcezu ezincane zikhiqizwa ngesikhathi sokugaya. Izinsalela ezincane, izinsalela ezikhiqiziwe zizovimba ishubhu ye-vacuum noma ziphule umsiki wokugaya ojikelezayo onesivinini esikhulu. Ukuwohloka kohlaka, ikakhulukazi lapho ubeka ipuleti lokugaya ngaphandle, kubangela ukuthi ipuleti eliqediwe liwohloke. Ngaphezu kwalokho, ukukhethwa kwendawo yokusika kanye nokulandelana kokucubungula kungenza ifreyimu Gcina ukuqina okukhulu kanye nesivinini esisheshayo. Uma ukukhethwa kungalungile, ifreyimu ikhubazekile kalula futhi ibhodi eliphrintiwe liyachithwa.

Amapharamitha enqubo yokugaya:

Sebenzisa i-cemented carbide milling cutter ukugaya ukuma kwebhodi eliphrintiwe. Ijubane lokusika le-milling cutter ngokuvamile liyi-180-270m/min. Ifomula yokubala imi kanje (ngokwereferensi kuphela):

S=pdn/1000 (m/min)

Indawo: PI (3.1415927)
