Peb paub tias cov ncej ncej yog qhov feem ntau ntawm precision machining, ua ntej kuv kuj tau qhia rau koj txog kev ua haujlwm ntawm cov ncej thiab cov teeb meem uas tau ntsib hauv kev ua, yog li hnub no kuv coj koj los nkag siab txog cov kev cai ntawm kev ua cov ncej ncej :.
Niaj hnub no peb hais los ntawm peb yam.
Ua ntej: qhov tseeb qhov loj me, phau ntawv xov xwm yog qhov tseem ceeb ntawm qhov chaw ntawm cov ncej, uas cuam tshuam rau qhov tseeb thiab kev ua haujlwm ntawm cov ncej. Txoj kab uas hla qhov tseeb ntawm phau ntawv journal feem ntau yog IT6 txog 9 raws li nws cov kev xav tau siv, thiab cov ntawv xov xwm precision tuaj yeem ncav cuag IT5.
Thib ob: geometric duab raug, cov duab geometric qhov tseeb ntawm cov ntawv xov xwm (roundness, cylindricity), feem ntau yuav tsum tau txwv rau txoj kab uas hla kam rau ua ntau yam. Thaum cov geometric duab raug qhov yuav tsum tau muaj siab, qhov tso cai kam rau ua tau cais cais nyob rau hauv daim duab kos duab.
Thib peb: qhov chaw ntawm kev ua, qhov tseeb feem ntau yog hais txog kev sib dhos ntawm cov khoom sib kis nrog cov ntawv xov xwm txheeb ze rau kev sib dhos ntawm cov kabmob txhawb nqa phau ntawv journal coaxiality, yog nrog cov ntawv xov xwm ntawm kev txhawb nqa phau ntawv journal radial ncig runout qhia; Raws li kev siv cov kev cai, cov kev cai ntawm siab precision ncej {{0}}}001 ~ 0.005mm, thiab dav dav dav ncej 0.01 ~ 0.03mm. Tsis tas li ntawd, muaj cov coaxiality ntawm sab hauv cylindrical nto thiab axial positioning kawg lub ntsej muag thiab axis perpendicularity yuav tsum tau.
Plaub: deg roughness, raws li qhov chaw ntawm qhov chaw ua haujlwm saum npoo, tuaj yeem muaj qhov sib txawv ntawm qhov sib txawv, xws li cov cuab yeej siv tshuab zoo tib yam spindle bearing journal nto roughness ntawm Ra{{0}}}.16 ~ {{4} }.63um, nrog rau cov ntawv xov xwm nto roughness ntawm Ra0.632.5um, nrog rau kev nce hauv tshuab ceev thiab precision degree ntawm kev txhim kho, ncej qhov chaw nto roughness tus nqi yuav tsum ua me thiab me.
