1. Cov txheej txheem ua haujlwm thiab kev ua tiav ntawm cov txheej txheem txheej txheej
Ncej, lub tes tsho, thiab disc qhov chaw yog cov khoom siv nrog rau sab nraud. Feem ntau siv cov txheej txheem machining rau sab nraud yog tig, sib tsoo thiab ntau txoj kev ua tiav. Txoj kev tig yog qhov ua tau zoo tshaj plaws rau cov txheej txheem sab nrauv, tab sis hais txog nws qhov tseeb ntawm kev lag luam, nws feem ntau tsim nyog raws li kev ua haujlwm ntxhib thiab ib nrab ua tiav rau sab nrauv; Kev sib tsoo ua tiav yog cov txheej txheem tseem ceeb ntawm lub voj voog sab nraud, tshwj xeeb tshaj yog tsim nyog rau kev ua tiav tom qab ntau yam siab hardness thiab quenching; Photofinishing yog ib qho ultra-precision machining txoj kev (xws li dov, polishing, sib tsoo, thiab lwm yam) tom qab ua tiav, uas yog tsim rau qee qhov chaw nrog siab precision thiab qhov chaw zoo. Txij li thaum kev lag luam machining raug, nto roughness, kev tsim khoom thiab cov nqi tsim khoom uas tuaj yeem ua tiav los ntawm ntau txoj kev ua haujlwm sib txawv, nws yog ib qho tsim nyog los xaiv txoj kev tsim nyog raws li qhov xwm txheej tshwj xeeb, txhawm rau ua cov khoom tsim nyog uas ua tau raws li qhov yuav tsum tau ua. cov duab kos duab.
2. Tig kev ua haujlwm ntawm lub voj voog sab nraud
(1) Txoj kev ua haujlwm tseem ceeb ntawm sab nraud ntawm qhov chaw ntawm cov ncej nyob rau hauv daim ntawv ntawm sab nraud tig yog tig ua. Cov ntaub ntawv tseem ceeb yog: khib nyiab tsheb dawb forgings thiab loj castings ntawm blanks, ua hauj lwm pub yog loj heev, thiaj li yuav txo tau qhov seem ntawm lub voj voog sab nrauv yuam kev thiab txoj hauj lwm sib txawv, kom cov txheej txheem tom qab ua nyiaj pub dawb yog uniform, tshem tawm cov txheej txheem. nto ntawm oxide nplai raws li kev ua vaj huam sib luag sab nrauv, qhov kev txiav dav dav yog 1-3mm ntawm ib sab. Rough tig Me me thiab nruab nrab-qhov loj me forging thiab casting blanks feem ntau ncaj nraim tig. Rough tig tsuas yog txiav feem ntau ntawm cov npoo ntawm qhov khoob (feem ntau tawm ntawm cov kauj ruam profile), thiab thaum lub rigidity ntawm cov txheej txheem tso cai, txiav ntau npaum li cas yuav tsum tau xaiv los txhim kho ntau lawm efficiency. Semi-finishing lem feem ntau yog siv los ua qhov kawg machining txheej txheem rau nruab nrab-precision qhov chaw, tab sis kuj tseem siv tau ua cov txheej txheem ua ntej rau kev sib tsoo thiab lwm yam machining. Rau blanks nrog siab precision, nws tuaj yeem ncaj qha semi-tiav yam tsis muaj kev sib hloov. Xaus txoj siav Kawg machining txheej txheem rau txheej txheej txheej txheej thiab ua ntej ua ntej ua tiav machining. Fine Vehicle Final processing processing for high-precision, fine-roughness surfaces. Nws yog qhov tsim nyog rau txheej txheej txheej txheej txheej ntawm cov hlau tsis yog hlau, tab sis vim tias cov hlau tsis muaj hlau tsis haum rau kev sib tsoo, kev sib tsoo zoo tuaj yeem siv los ntawm kev sib tsoo. Txawm li cas los xij, zoo tig yuav tsum tau siv cov cuab yeej siv nrog kev ua haujlwm siab, zoo rigidity, ruaj khov kis tau tus mob, micro pub, thiab tsis muaj qhov tshwm sim nkag. Cov cuab yeej pob zeb diamond lossis carbide yog siv los tig, lub kaum sab xis ntawm lub cuab yeej loj dua (45 o -90 o), thiab lub vojvoog arc ntawm lub cuab yeej yog tsawg dua 0.{{15} } 0mm, [1]
(2) Kev siv txoj kev tig
1) Ordinary tig yog tsim rau ntau yam batch ntawm ncej qhov chaw sab nraud ncig ua, thiab yog dav siv. Ib qho me me feem ntau siv cov tshuab dhos chav pw kom ua tiav kev ua tiav; Nruab nrab batch thiab ntau lawm siv tsis siv neeg, semi-automatic lathes thiab tshwj xeeb lathes kom tiav txoj kev ua. 2) CNC tig yog tsim rau ib qho me me batch thiab nruab nrab batch ntau lawm. Daim ntawv thov tau dhau los ua ntau dua, thiab nws cov txiaj ntsig tseem ceeb yog kev hloov pauv zoo, hloov khoom siv luv luv thiab lub sijhawm npaj thaum hloov cov khoom siv; Tsawg lub sijhawm pabcuam thaum lub sijhawm ua haujlwm, uas tuaj yeem txhim kho kev ua haujlwm tau zoo los ntawm kev ua kom zoo ntawm kev txiav thiab kev tswj hwm kev tswj hwm; Kev ua haujlwm zoo, tsis tshua muaj kev sib tw tshwj xeeb, tsawg tus nqi npaj ntau lawm; Cov kev xav tau ntawm cov cuab yeej siv tshuab ua haujlwm tsawg, thiab nws tsis cuam tshuam los ntawm kev txawj ntse, lub zeem muag, tus ntsuj plig, lub zog lub cev thiab lwm yam ntawm tus neeg teb xov tooj. Rau cov ncej, CNC tig yog tsim rau cov yam ntxwv hauv qab no. Cov khoom uas muaj cov qauv los yog cov duab, kev ua haujlwm yooj yim yooj yim, cov neeg ua haujlwm ntev-teev thiab kev ua haujlwm tsawg. Cov khoom uas xav tau siab rau kev sib xws hauv kev ua haujlwm raug. Cov khoom uas muaj qhov sib txawv ntawm kev txiav, xws li cov khoom uas yuav tsum tau grooved, tig, tig threads, thiab lwm yam vim yog cov yam ntxwv zoo, yuav tsum hloov qhov txiav ntau zaus thaum ua. Lub batch tsis loj, tab sis txhua batch ntawm qhov chaw nrog ntau yam sib txawv thiab ib qho kev sib txawv ntawm cov khub nrog keyway, radial qhov (xws li lub qhov taub hau), kawg lub ntsej muag nrog lub qhov (suav nrog cov ntsia hlau qhov) system ntawm ncej, xws li ncej. nrog flange, ncej nrog keyway lossis square taub hau, kuj tseem tuaj yeem ua tiav ntawm qhov chaw machining, ntxiv rau CNC tig zoo tib yam, ntau yam grooves, qhov (xws li cov ntsia hlau qhov), qhov chaw thiab lwm qhov chaw ntawm cov khoom tuaj yeem ua tiav. Cov txheej txheem yog cov concentrated, nws cov kev ua tau zoo yog siab dua li CNC tig, thiab qhov tseeb machining yog ruaj khov thiab txhim khu kev qha. 3) Cov txheej txheem ntawm kev ua haujlwm ntawm qhov chaw ua haujlwm nrog cov cuab yeej abrasive rau kev sib tsoo cov txheej txheem ntawm cov kab nrawm yog hu ua kev sib tsoo. Kev sib tsoo yog ib txoj kev txiav ceev nrog ntau yam cuab yeej thiab cov npoo, uas yog siv rau kev ua tiav ib feem thiab nyuaj deg machining. Kev sib tsoo muaj ntau yam txheej txheem thiab tuaj yeem muab faib ua ntxhib sib tsoo, sib tsoo zoo, sib tsoo zoo thiab daim iav sib tsoo. Cov abrasives (los yog abrasives) siv nyob rau hauv kev sib tsoo muaj cov yam ntxwv ntawm cov khoom me me, siab hardness thiab zoo tshav kub tsis kam, yog li cov khoom siv hlau tawv thiab cov khoom tsis yog xim hlau tuaj yeem ua tiav, xws li cov hlau tawv, cov cuab yeej carbide, ceramics, thiab lwm yam. Nyob rau hauv tus txheej txheem ntawm machining, muaj ntau yam hais koom nyob rau hauv lub txiav txav nyob rau tib lub sij hawm, thiab nyias nyias thiab zoo heev chips yuav raug tshem tawm, yog li cov machining raug yog siab thiab cov nto roughness tus nqi yog me me. Raws li txoj kev ua tiav, kev sib tsoo yog siv dav hauv kev tsim khoom. Ua tsaug rau txoj kev loj hlob ntawm kev sib tsoo hnyav, cov khoom lag luam tseem tuaj yeem ua rau hauv av ncaj qha mus rau qhov yuav tsum tau muaj qhov ntev thiab qhov tseeb, uas ua rau muaj txiaj ntsig zoo.
