1. Cov txheej txheem rau kev txhim kho nto tiav
Nws yog feem ntau muab faib ua ob hom: ntxiv cov txheej txheem sib xws thiab kev txhim kho thiab ntxiv cov txheej txheem sib xws ntawm cov txheej txheem qub: ntxiv polishing, sib tsoo, scraping, dov thiab lwm yam txheej txheem tuaj yeem tsis tsuas yog txhim kho smoothness tab sis kuj txhim kho qhov tseeb; Tsis tas li ntawd, ultrasonic dov tshuab, ua ke nrog cov hlau yas fluidity, muaj nyob rau hauv ob qho tib si hauv tsev thiab txawv teb chaws, uas txawv ntawm kev ua haujlwm txias txias los ntawm dov. Nws tuaj yeem txhim kho roughness los ntawm 2-3 qib thiab tseem txhim kho tag nrho cov khoom siv.
2.Yuav ua li cas txhim kho cov txheej txheem
① Tsim nyog xaiv txiav ceev. Txiav ceev V yog qhov tseem ceeb cuam tshuam rau saum npoo roughness. Thaum ua cov ntaub ntawv yas, xws li cov hlau nruab nrab thiab cov pa roj carbon tsawg, cov kev txiav qis qis yog qhov ua rau cov nplai thiab cov burrs, thaum nruab nrab ceev yog qhov tsim ntawm cov chips deposits, uas yuav ua rau kom cov roughness. Kev zam qhov nrawm no yuav txo qhov roughness tus nqi. Yog li tsis tu ncua tsim tej yam kev mob los txhim kho kev txiav ceev yeej ib txwm yog ib qho tseem ceeb kev taw qhia rau kev txhim kho qib ntawm technology.
② Tsim nyog xaiv tus nqi pub. Qhov loj ntawm tus nqi pub ncaj qha cuam tshuam qhov roughness ntawm lub workpiece. Feem ntau, qhov me me ntawm cov khoom noj, qhov me me ntawm qhov roughness, thiab smoother lub workpiece nto.
③ Tsim nyog xaiv qhov ntsuas geometric ntawm cov cuab yeej txiav. Pem hauv ntej thiab nram qab cov ces kaum. Ua kom lub kaum sab xis pem hauv ntej tuaj yeem txo qhov deformation thiab kev sib txhuam ntawm cov khoom siv thaum txiav, thiab tseem txo qhov kev txiav tag nrho, uas yog qhov zoo rau kev tshem tawm cov nti. Thaum lub kaum sab xis tam sim no raug kho, lub kaum sab xis loj dua, qhov me me ntawm lub vojvoog ntawm qhov txiav ntug, thiab cov hniav ntse dua; Tsis tas li ntawd, nws tseem tuaj yeem txo qhov kev sib txhuam thiab extrusion ntawm lub nraub qaum txiav nto thiab lub tshuab ua haujlwm thiab qhov chaw hloov pauv, uas yog qhov zoo rau kev txo cov nqi roughness. Ua kom lub vojvoog arc r ntawm cov cuab yeej taw qhia tuaj yeem txo nws cov nqi roughness; Txo lub kaum sab xis deflection Kr ntawm lub cuab yeej kuj tuaj yeem txo nws qhov roughness tus nqi.
④ Xaiv cov khoom siv tsim nyog. Cov cuab yeej nrog thermal conductivity zoo yuav tsum raug xaiv kom xa cov cua sov kom raws sijhawm thiab txo cov yas deformation hauv cheeb tsam txiav. Tsis tas li ntawd, cov cuab yeej txiav yuav tsum muaj cov khoom siv tshuaj zoo los tiv thaiv kev sib raug zoo ntawm cov cuab yeej txiav thiab cov khoom ua tiav. Thaum cov affinity siab dhau lawm, nws yog ib qho yooj yim los tsim cov chips thiab nplai, ua rau ntau dhau ntawm qhov roughness. Yog tias cov khoom siv tawv tawv lossis cov khoom siv ceramic yog coated rau ntawm nws qhov chaw, oxidation tiv thaiv zaj duab xis yog tsim rau ntawm qhov chaw txiav thaum txiav, uas tuaj yeem txo qhov kev sib txhuam coefficient ntawm nws thiab lub tshuab ua haujlwm, yog li txhim kho qhov smoothness.
⑤ Txhim kho kev ua haujlwm ntawm cov khoom siv ua haujlwm. Lub toughness ntawm cov khoom txiav txim siab nws plasticity, thiab nrog zoo toughness, muaj peev xwm ntawm yas deformation yog ntau dua. Thaum lub sij hawm mechanical ua, qhov roughness ntawm qhov chaw nce.
⑥ Xaiv cov kua txiav uas tsim nyog. Kev xaiv kom raug ntawm cov kua txiav tuaj yeem txo qhov roughness ntawm qhov chaw. Cov kua txiav muaj cua txias, lubrication, tshem tawm cov nti, thiab ntxuav cov haujlwm. Nws tuaj yeem txo qhov kev sib txhuam ntawm cov khoom ua haujlwm, cov cuab yeej, thiab cov nti, tshem tawm cov cua kub ntau, txo qhov kub ntawm qhov chaw txiav, thiab tshem tawm cov chips me me raws sijhawm.
