Raws li cov ntsiab lus sib kis ntawm cov khoom siv twj tso kua mis, cov hlau tso kua mis tau txais kev xav tau siab heev rau qhov tseeb, lub zog thiab hnav tsis kam. CNC machining thev naus laus zis tuaj yeem ua tiav kev tsim khoom muaj txiaj ntsig thiab raug ntau. Cov hauv qab no yog kev ua tiav kev nyeem ntawv rauCNC Raug Steel Plab Ncej.
1. Khoom npaj npaj thiab Pretrice
Nyiam dua 45 # cov roj carbon zoo carbon cov hlau lossis 40cr alstoy cov qauv hlau. Cov ob cov ntaub ntawv tuaj yeem ua tau raws li cov kev ua tau zoo ntawm cov tshuab nqus tsev tom qab kev kho cua sov. Cov ntaub ntawv nyoos yuav tsum tau ncaj, thiab tus curvature yog tswj tsis pub dhau 0.05 hli / m los ntawm kev siv lub tshuab ua haujlwm ruaj khov rau. Tom qab ntawd txoj kev ntxhib yog nqa tawm, thiab 8-10mm machining pub tshwj tseg raws li qhov loj me ntawm cov khoom tiav. Nyob rau tib lub sijhawm, cov txheej txheem Ejector lub qhov yog drilled nyob rau hauv nruab nrab ntawm ob kawg ntsej muag los muab ib qho chaw ua haujlwm muab cov c cylindrical sab nraud.
2. CNC Tshuab Dhos Hnyav Ua
Xaiv lub tshuab dhos CNC tau nruab nrog carbide sab nraud cylindrical tig tuam. Thaum sau cov kev pab cuam nruj heev machining Thaum lub sij hawm cov txheej txheem machining, nws yog qhov tsim nyog yuav tsum nres thiab tshawb xyuas qhov ua haujlwm kub txhua 300mm txiav ntev. Yog tias nws tshaj 60 degree, nws yuav tsum tau txias nrog emulsion; Cov khoom noj ceev tau teeb tsa rau 80-100mm / min, thiab lub spindle ceev tau tswj hwm ntawm 800r / min kom tsis txhob muaj kev cuam tshuam ntawm lub zog txiav ntau dhau los.
3. Kev kho cua sov muaj zog
Lub workpiece tom qab siv ntxhib machining yuav tsum tau npau taws: ua kom sov rau 250℃(405 # Qhov kawg hardness yuav tsum mus txog 220-250hbw. Tom qab kev kho cua sov, kev kho mob laus yuav tsum tau tshem tawm sab hauv kev ntxhov siab. Lub workpiece tau muab tso rau ib txwm rau 48 teev, lossis khaws cia sov rau hauv 120℃qhov cub rau 6 teev.
4. CNC KWS DHOS TOINISHING
Hloov nrog lub precision CNC tshuab dhos (muab tso rau qhov tseeb 0.01 hli), thiab cov cuab yeej hloov nrog lub ceramic CMN hniav txhawm rau txhim kho qhov chaw zoo. Cov ntawv adopts ua tiav "ib qho kev kawm thiab ib qho txheej txheem sab saum toj" clamping, thiab cov tailstock ejector PIN siv lub zog sab saum toj ntawm 0.2-0.3mpa. Cov khoom tseem ceeb nrog:
Matching Ncej caj ces yuav tsum tau mus txog IT6 qib (φ50h6), nto rougness ra1.6μμ
Foob Nplhaib Grittha: Groove Dav Dagrance yog tswj ntawm ± 0.02 hli, thiab parallelism ntawm qhov zawj hauv qab thiab lub axis yog tsawg dua lossis sib npaug rau 0.015mm;
Cov xov kawg xov: Siv G76 Xov Txiav Mus Ua Rau Cov Txheej Txheem M20 × 1.5 xov paj, thiab cov hniav sib txawv tsis tshaj 1 degree.
5. CNC Milling Tshuab Kev Ua
Hloov mus rau CNC Milling Tshuab, siv High-Ceev Hlau Milling Cutter (Olyb12mm) los ua tus txheej txheem xa kis. Los ntawm kev ua haujlwm ntawm lub voj voog lub voj voog ua ke, txheej txheej Milling Tom qab kev ua tiav, qhov tseem ceeb thiab cov ntawv xov xwm kev ua ntaub ntawv yuav tsum tau tshawb xyuas nrog kev mus thiab tsis muaj ntsuas.
6. Precision sib tsoo thiab kev kho kom nto
Cov txheej txheem kawg tau siv cylindrical grinder rau kev ua zaum kawg, sib tsoo sab nraud lub voj voog rau φ50h5, thiab cov kev sib tw yog tswj tsis pub dhau 0.005mm. Rau cov ntawv xov xwm mating saum npoo, kev polishing yog qhov yuav tsum tau, siv lub wool log nrog chromium oxishing polishing polishing paste kom nce sab saum npoo roughness rau ra0.8μm. Qhov chaw tsis sib xws tuaj yeem yog blackened kom txhim kho cov xeb tsis kam.
7. Kev Soj Ntsuam Zoo
Siv peb lub tshuab ntsuas sib txuas ua ke los soj ntsuam qhov tseem ceeb ntawm cov ntsiab lus yuam kev tsis ua yuam kev yog tsawg dua lossis sib npaug zos yog tsawg dua lossis sib npaug rau 0.01mm. Siv cov hlau nplaum ua kom pom kom pom kom meej kom paub meej tias tsis muaj qhov tsis xws luag zoo dua 0.2mm}}% ntawm cov workpieces yog kev kuaj xyuas torque. Daim ntawv 45 # steel twj tso kua mis yuav tsum tau ua kom muaj ntau dua lossis muaj sib npaug rau 300 xm m tsis muaj deformation.
Thaum lub sijhawm CNC tsim khoom ntawm cov hlau twj tso kua nplaum, tshwj xeeb Thaum lub sij hawm loj heev, lub cuab yeej nyiaj them yuav tsum muaj calibrated txhua 2 teev kom ntseeg tau qhov ruaj khov sab ruaj khov. Nrog cov txheej txheem no kev daws teeb meem, huab hwm coj ntau lawm ntawm cov steel twj tso nrog cov kauj ruam dhau ntawm 98% tuaj yeem ua tiav. Yog tias koj xav tau CNC Machining ntawm cov hlau tso kua mis ncej cov khoom siv, tiv tauj peb rau cov lus hais.
