Xov milling yog ua kom tiav xov milling nrog kev pab los ntawm peb-axis linkage muaj nuj nqi ntawm CNC machining chaw thiab G02 los yog G03 kauv interpolation hais kom ua.Txoj kev xov milling nws tus kheej muaj qee yam zoo.
Vim tias cov khoom siv tam sim no ntawm cov xov milling cutters yog cov alloys nyuaj, kev ua haujlwm ceev tuaj yeem ncav cuag 80-200m / min, thaum ua haujlwm ceev ntawm high-speed steel hlau cones tsuas yog 10-30m / min.Yog li ntawd, xov milling cutters yog tsim rau high-ceev txiav thiab nto tiav ntawm cov txheej txheem threads kuj zoo heev.
Cov xov machining ntawm cov ntaub ntawv siab hardness thiab high-temperature alloy cov ntaub ntawv, xws li titanium alloy thiab npib tsib xee raws alloy, yeej ib txwm yog ib qho teeb meem nyuaj, feem ntau vim hais tias high-ceev steel cones muaj ib tug luv luv lub neej cuab tam thaum machining threads ntawm cov ntaub ntawv no. .Txawm li cas los xij, siv lub zog alloy xov milling cutter rau machining cov ntaub ntawv nyuaj threads yog ib qho kev daws teeb meem zoo tshaj plaws.Lub machinability hardness yog HRC58-62.Rau xov ua cov ntaub ntawv kub-kub alloy, xov milling cutters kuj qhia tau zoo heev machining kev ua tau zoo thiab npaj txhij txog ntev lifespan.Rau threaded qhov nrog tib lub suab thiab sib txawv diameters, siv tus kais rau machining yuav tsum tau ntau yam cuab yeej txiav kom tiav.Txawm li cas los xij, yog tias siv xov milling cutter rau machining, tsuas yog ib qho cuab yeej txiav tuaj yeem siv tau.Tom qab cov kais dej yog hauv av thiab cov xov xov loj yog tsawg dua qhov kam rau ua, nws siv tsis tau lawm thiab tsuas yog muab pov tseg;Thaum cov xov milling cutter yog hnav thiab qhov loj ntawm cov txheej txheem xov qhov yog tsawg dua qhov kam rau ua, cov cuab yeej tsim nyog lub vojvoog them nyiaj hloov kho tuaj yeem ua los ntawm CNC system mus txuas ntxiv cov txheej txheem tsim nyog.Ib yam li ntawd, txhawm rau kom tau txais cov xov zoo siab, siv cov xov milling cutter los kho cov cuab yeej lub vojvoog yog yooj yim dua li ua cov kais dej siab.Rau me me txoj kab uas hla xov ua, tshwj xeeb tshaj yog rau siab hardness thiab high-temperature cov ntaub ntawv, lub kais dej tej zaum yuav tawg, thaiv lub threaded qhov, thiab txawm ua rau cov seem yuav tsum scrapped;Siv cov xov milling cutter, vim qhov me me ntawm lub cuab yeej piv rau lub qhov ua tiav, txawm tias nws tawg, nws yuav tsis thaiv lub hauv paus xov qhov, ua rau nws yooj yim heev rau tshem tawm thiab yuav tsis ua rau cov khoom seem;Los ntawm kev siv xov milling, txiav quab yuam ntawm cov cuab yeej txiav yog txo qis piv rau cov kais dej, uas yog qhov tseem ceeb tshwj xeeb rau kev ua cov kab loj loj.Qhov no daws tau qhov teeb meem ntawm lub tshuab cuab yeej overloaded thiab tsis muaj peev xwm tsav tus kais rau ib txwm machining.Lub tshuab clamp hniav hom xov milling cutter tau qhia ib xyoo dhau los, thiab tib neeg kuj pom tau hais tias thaum machining threaded qhov saum M20 ntawm lub tshuab machining chaw. , siv xov milling cutter tuaj yeem txo cov nqi ua piv rau kev siv kais.Txawm li cas los xij, nyob rau hauv xyoo tas los no, kev tsim thiab kev siv tshuab ntawm tag nrho cov tawv alloy xov milling cutters tau maj mam loj hlob, thiab cov khoom lag luam nrog ntau qhov ntau thiab tsawg tau tsim.Rau daim ntawv thov ntawm me me txoj kab uas hla xov machining, ib tug aviation enterprise yuav tsum tau ua 50 M1.6 × 0.35 xov drilling qhov ntawm ib tug txhuas tivthaiv.Cov neeg siv khoom tau ntsib teeb meem: vim qhov qhov muag tsis pom kev, kev tshem tawm cov nti yog qhov nyuaj, thiab nws yooj yim tawg thaum siv tus kais rau machining;Raws li tapping yog cov txheej txheem kawg, yog tias qhov seem tau muab pov tseg, lub sijhawm ua haujlwm tseem ceeb siv rau ntawm ntu yuav ploj tag nrho.Thaum kawg, tus neeg siv khoom xaiv cov xov milling cutter rau kev ua M1.6 × 0.35 threads, nrog cov kab nrawm ntawm Vc = 25m / min thiab qhov ceev ntawm S = 4900r / min (tshuab txwv), thiab pub tus nqi ntawm fz = 0.05 mm/r ib revolution.Lub sijhawm ua haujlwm tiag tiag yog 4 vib nas this ib lub xov, thiab tag nrho 50 workpieces tau ua tiav nrog ib lub cuab yeej.
Ib qho kev txiav cov cuab yeej tsim khoom lag luam, vim tias qhov dav dav ntawm cov cuab yeej txiav lub cev yog HRC44, nws yog qhov nyuaj rau siv cov hlau xaim ceev ceev los ua cov kab me me threaded qhov uas ntim cov hniav.Lub cuab yeej lub neej yog luv thiab yooj yim tawg.Rau M4x0.7 xov ua, cov neeg siv khoom xaiv cov khoom carbide xov milling cutter nrog Vc = 60m / minFz = 0.03mm / r ua lub sij hawm ntawm 11 vib nas this / xov, thiab lub cuab tam lub neej ncav cuag 832 threads, nrog zoo heev xov tiav.
Nruab nrab txoj kab uas hla xov machining yuav tsum tau siv peb qhov ntau thiab tsawg ntawm threaded qhov, M12x0.5, M6x0.5, thiab M7x0.5, ntawm txhuas qhov chaw yuav tsum machined los ntawm ib tug tej enterprise, nrog tib lub suab.Yav dhau los, peb hom kais dej yuav tsum tau ua kom tiav cov machining.Peb tam sim no siv cov xov milling cutter nrog tej yam kev mob: Vc = 100m / min, S = 8000r / min, fz = 0.04mm / r.Lub sijhawm ua haujlwm rau ib lub xov tooj yog 4 vib nas this, 3 vib nas this, thiab 3 vib nas this, feem.Ib lub cuab yeej tuaj yeem ua 9000 xov.Tom qab ua tiav tag nrho batch ntawm cov khoom ua tiav, cov cuab yeej tseem tsis tau puas lawm.
Hauv kev tsim hluav taws xob loj thiab cov cuab yeej siv hlau ua cov khoom lag luam, nrog rau lub twj tso kua mis thiab lub valve ua kev lag luam, xov milling cutters tau daws qhov teeb meem ntawm machining loj txoj kab uas hla threads, dhau los ua cov cuab yeej zoo tshaj plaws machining nrog kev ua haujlwm siab thiab tus nqi qis.Piv txwv li, qee qhov kev ua haujlwm ntawm lub valve yuav tsum tau ua 2 "x11BSP-30 threads ua los ntawm cov hlau cam khwb cia thiab cia siab tias yuav txhim kho kev ua haujlwm zoo.Los ntawm kev xaiv ib lub chips thiab ntau lub tshuab clamp hom xov milling cutter, siv cov kev txiav ntawm Vc = 80m / min, S = 850r / min, fz = 0.07mm / r, lub sijhawm ua haujlwm yog 2min / xov, thiab cov hniav lub neej yog 620 daim, zoo txhim kho kev ua tau zoo ntawm txoj kab uas hla loj threads.
Xov milling cutters, raws li cov cuab yeej tshaj lij uas tau tsim sai heev nyob rau xyoo tas los no, tau txais kev lees paub los ntawm cov tuam txhab thiab nthuav tawm kev ua haujlwm zoo, dhau los ua riam phom muaj zog rau cov lag luam los txo cov nqi xov, txhim kho kev ua haujlwm, thiab daws cov teeb meem xov.
