Dab tsi milling cutter yog siv nyob rau hauv cov lag luam wholesale PCBS v {{cut zawv ziab kev ncig tshuab?

 

Hauv PCB tsim cov txheej txheem, v {- grooving yog ib qib tseem ceeb uas txiav txim siab qhov tseeb thiab ntug zoo ntawm lub rooj tsavxwm. Qhov kev xaiv ntawm milling cutter ncaj qha cuam tshuam ncaj qha cuam tshuam txiav cov txiaj ntsig, ntau lawm kev ua haujlwm, thiab cuab tam lub neej. Raws li cov tub ntxhais tseem siv rau lubLag luam wholesale PCBS V txiav cov tshuab puab toj siab, qhov kev xaiv zoo ntawm v - Grooving cutter yuav tsum muaj kev txiav txim siab ntawm ntau yam, thiab machining qhov tseeb yuav tsum tau.

Cov khoom xaiv ntawm v {{0} Grooving cutter siv nyob rau hauv cov kev lag luam Groove rebinging yog qhov tseem ceeb machining zoo. Tam sim no, kev lag luam tseem siv ultrafine {{3} nplej} nplej carbide li cov khoom tseem ceeb. Cov cutters yog tsim los ntawm import ultrafine - nplej tungsten carbide alloy. Los ntawm precision moulding, lawv tau ua tiav tsis meej txoj kab ntawm 0.175mm, muab cov kev tiv thaiv zoo thiab cuam tshuam. Nws cov qauv hlau qauv ntom ntom yog siab dua li ntawm cov cemented cemented carbide, cia nws los tswj lub ntsej muag ntse txawm tias nyob rau hauv high- ceev cov chaw ib puag ncig. Nws yog tsim tshwj xeeb rau kev nruam machbers ntawm cov ntaub ntawv pcb nruj xws li Fry 4 Epoxy cov laug cam nrog cov tuab tuab los ntawm 0.2mm rau 6.0mm.
Pob zeb diamond -} coated cutters kev muab cov cim tshwj xeeb rau high {1} precision v {{grooving. Pob zeb diamond txiav cov npoo, tsim kom siv tus tuag - spark electro {}} kev ua kom zoo los ntawm "luam tawm cov duab hluav taws xob. Ua ke nrog cov nplooj siab hydraulic tension lub tes tsho tshem tawm, lawv ua tiav qhov tseeb ntawm tsawg dua lossis sib npaug rau 0.015mm. Cov txheej txheem no ua rau cov kev tawm hauv peb theem: Roughing, ua tiav} {qib dego rougness ntawm kev txiav ntug. Qhov no ua rau nws zoo tagnrho rau micro {13} grooving siab cov ntaub ntawv xws li ceramic saim thiab aluminium- based compels.
Tsoos kev ua kom siab - ceev hlau (hss) milling cutters tseem ua lub luag haujlwm hauv cov ntawv thov tshwj xeeb. Ua los ntawm alloys xws li w6mo5crr4v2, lawv tswj tau ruaj khov txiav kev ua haujlwm ntawm kev ua haujlwm kub tsawg dua lossis sib npaug nrog 600 degree. Hom milling cutter no muaj tus nqi qis thiab, los ntawm kev txiav lub kaum sab xis ntawm Qis {{10} Precision PCBs. Nws yog qhov haum rau roughing nyob rau hauv pawg ntau lawm lossis rau tus nqi- rawv cov ntawv thov.

Cov qauv tsim qauv ntawm v - Grooving milling cutter ncaj qha cuam tshuam kev ua tau zoo thiab machiner tsis muaj peev xwm ua tau zoo thiab machiner ruaj khov. Ib Leeg - stre}}}}}}}}}}}}}}}}} Cov qauv tsim no tshwj xeeb yog zoo - zoo nkauj rau cov khoom nplaum xws li PVC Subttrates ntawm cov laug cam thiab cov cuab yeej tsis tshua muaj thiab txiav suab nrov.
Ob npaug - ntug milling c quavtrters ua tiav cov txheej txheem sib npaug, txo qis kev co ntawm kev kub ceev. Ua ke nrog ob lub siab - muaj peev xwm nti thiab haus luam yeeb tiam thaum tshuab nruab nrab} Qhov rigidity ntawm ob npaug -} edged qauv kev ruaj khov thaum txiav v {} grooves ntawm cov ces kaum ntawm cov ces kaum xws li 60 degree. Nws yog qhov tshwj xeeb tsim nyog rau grooves yuav tsum muaj kev sib txawv, ua tiav cov nplaim hauv qab no Ra0.8μm.

Lub kaum sab xis xaiv yuav tsum tau qhia meej rau lub PCB tuab thiab faib cov cai. 30} grooving ntawm nyias pcbs (0.2} 1.0mm), txo kev ntxhov siab thaum txiav. Ib qho 45℃kaum sab xis yog ib qho kev xaiv dav dav, ntsuas qhov tseeb, thiab yog siv cov thicknesses ntawm 1.0-3.0 hli. Ib tug 60℃lub tshuab milling cutter yog qhov tsim rau kev ua cov laug cam tuab tshaj 3.0 hli, nrog nws cov ntug ntau dua muaj peev xwm txiav cov khoom ntim. Cov ces kaum kev cai (xws li 20℃thiab 50 degree) muaj raws cov kev cai tshwj xeeb kom ntseeg tau tias muaj kev cuam tshuam kev ntxhov siab ntawm kev sib sau ua ke.

Lub hliav milling cutter txoj kab yuav tsum yog ua kom zoo rau v - Grite tob. Ib txoj kab uas hla ntawm 2 {{{{{}} 3 lub sij hawm lub zawj qhov tob feem feem feem ntau pom zoo. Cov txheej txheem kev lag luam ntawm cov cheeb tsam muaj ntau yam los npog 0.175mm rau 3.175mm, nrog 1.0 teev} Me- diam milling txiav (tsawg dua los yog sib npaug rau qhov nqaim grove machining ntawm high- density PCBs. Thaum paired nrog lub siab - ceev spindle (saum 40,000 rpm), lawv tau siab- precision txiav. Loj-txoj kab txiav (ntau dua los yog sib npaug rau 2.5mm) yog qhov tsim nyog rau kev siv lub tshuab loj loj ntawm cov lej loj.

Matching tej tsis yog tus yuam sij rau kev ua tiav cov kev ua kom zoo tshaj plaws millingal cutter. Cov kev pom zoo txiav ceev ceev rau carbide milling cutters yog 150 {{}} 300 m / min, nrog tus nqi pub ntawm 50-200 mm / min. Qhov kev nrawm no yuav tsum tau hloov kho raws li lub hardness ntawm substrate. Rau PCBs nrog cov iav fiber ntau, ib qho kev pom zoo qis dua, thaum lub sijhawm ua rau cov ntsiab lus resin ntau, tus nqi pub yuav tau nce siab. Pob zeb diamond milling cutters tuaj yeem ua haujlwm ntawm kev txiav ntau dua (300-500 m / min), tab sis lawv yuav tsum tau nruab nrog qhov txias txias kom tiv thaiv kev kub siab los ntawm kev ua kom cov txheej kub.

Qhov kev xaiv ntawm milling cutter hom nyob ntawm PCB cov yam ntxwv ntawm PCB cov yam ntxwv cutters tuaj yeem siv rau cov qauv fr - 4 substrates. Rau txhuas - based pcbs, ib leeg- ntug txiav kev txhuas cov chips los ntawm cutter. Rau cov pcbs flexible, ultra - nplej} nplej {8} grain {8} Cov kab laum zoo, raws li lawv optimized ntug vojvoog txo cov khoom tawg. Rau tuab tooj liab pcbs, righting ob chav milling cutters tau pom zoo, raws li lawv cov rigidity ntau ntxiv tsis kam ntawm cov txheej txheem tooj liab.

Tsim nyog ntawm kev tsim nyog tuaj yeem nthuav dav milling txiav lub neej. Yog tias cov khoom siv hluav taws xob zoo tshaj, siv lub zog siv hluav taws xob nce rau ntawm kev txiav ntoo, cov milling cutter yuav tsum tau rov kho kom sai. Regrinding yuav tsum precision hliav cov khoom thiab lub diamond diamond sib tsoo log. Lub kaum lub kaum sab xis thawj yuav tsum nruj nruj tswj kom muaj tseeb tsis txhob mob siab los yog cov npauj me me tom qab hliav. Qhov tob tob yuav tsum ua raws li zam kom tsis txhob muaj alloy overshoot.

Cov ncauj lus kom ntxaws tswj thaum siv txhua hnub yog ib qho tseem ceeb ib yam nkaus. Ua ntej kev teeb tsa, tshem cov khib nyiab los ntawm spindle thiab flange, thiab ua kom cov cuab yeej ua kom haum rau 0.02mm. Xyuas kom meej clamping tob thaum clamping lub cuab tam; Ib qho ntawm tsawg kawg yog 1.5 zaug ntawm Shang txoj kab feem ntau pom zoo kom ntseeg tau tias muaj kev ruaj khov thaum txiav. Tswj tus nqi pub mis tas li thaum lub tshuab kom tsis txhob muaj kev lom zem uas tuaj yeem ua rau muaj kev puas tsuaj hauv cheeb tsam thiab txiav ntug kev puas tsuaj.

Tswj cov cia thiab tig ntawm milling cutters. Zam kev nyiag lossis sib chwv nrog cov khoom hlau thaum lub sijhawm cia. Nws yog qhov zoo tshaj plaws rau khw hauv thawj lub ntim kom tiv thaiv kev puas tsuaj los ntawm kev cuam tshuam. Milling txiav kev yuav khoom yuav hauv qhov yuav tsum yog kev siv lub cav, kaw tus naj npawb ntawm cutters thiab hom ntawm substrates ua tiav. Kev tsom xam txheeb xyuas cov ntsiab lus yuav tsum tau siv los txiav txim siab hloov kev hloov kho tshiab. Kev tshawb fawb tau qhia tias kev yuav txais cov cuab yeej kev tswj hwm kev tswj hwm tau txuas ntxiv tuaj yeem txuas cov nqi cutter los ntawm ntau dua 30% thaum txo cov nqi siv rau ib qho khoom lag luam.

Xaiv v - grooving milling cutter rau pcbs yog ib txheej txheem kev tshawb fawb, kev tsim kho tshuab, thiab machinesient tsim qauv, thiab machinesient tsim qauv, thiab machinesient tsim qauv, thiab machinesient tsim, thiab machinesient tsim, thiab machinesient tsim qauv, thiab machinesient tsim qauv, thiab machinesient tsim Los ntawm ultra - zoo carbide rau pob zeb diamond tshem tawm, ntawm ib qho kev tsim kho thev naus laus zis txhim kho kom zoo thiab ua haujlwm ntawm PCB droaneling. Kev xaiv kom zoo thiab siv v {{6} Grooving milling cutters tsis tsuas yog ua kom cov nqi txiav ntau lawm thiab tseem txhim kho kev ruaj khov. Raws li PCBbs txav mus rau qhov chaw ceev dua thiab thinner profile, tshwj xeeb {...
