Kev kam rau siab yog qhov kev lees paub ntawm qhov ntev txiav txim siab los ntawm tus tsim qauv raws li cov duab, haum thiab kev ua haujlwm ntawm ib feem. Kev nkag siab txog yuav ua li cas CNC machining tolerances cuam tshuam rau tus nqi, kev tsim cov txheej txheem xaiv, kev tshuaj ntsuam xyuas thiab cov ntaub ntawv tuaj yeem pab koj txiav txim siab cov khoom tsim zoo dua.
1. Tighter tolerances txhais tau tias cov nqi nce
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kev tiv thaiv nruj dua yuav raug nqi ntau dua vim muaj cov khoom seem ntxiv, cov khoom siv ntxiv, cov cuab yeej ntsuas tshwj xeeb thiab / lossis lub sij hawm voj voog ntev dua, vim tias lub tshuab yuav tsum tau ua kom qeeb kom tswj tau nruj dua. Nyob ntawm qhov kev tolerance callout thiab cov geometry txuam nrog nws, tus nqi tuaj yeem ua tau ntau tshaj li ob zaug raws li kev tswj hwm tus qauv.
Lub ntiaj teb geometric kam rau ua kuj tuaj yeem siv rau kev kos duab ntawm qhov chaw. Nyob ntawm qhov ntev ntawm geometric kam rau ua thiab hom kev kam rau siab thov, cov nqi ntxiv yuav raug tshwm sim vim muaj sijhawm tshuaj xyuas ntau ntxiv.
Txoj hauv kev zoo tshaj plaws los thov kev zam txim yog tsuas yog siv nruj lossis geometric kam rau cov chaw tseem ceeb thaum nws tsim nyog kom ua tau raws li cov qauv tsim kom txo tus nqi.
2. Tighter tolerances yuav txhais tau hais tias kev hloov ntawm cov txheej txheem tsim
Kev qhia kom nruj dua qhov kev zam dhau ntawm tus qauv kev zam tuaj yeem hloov qhov kev tsim khoom zoo rau ib feem. Piv txwv li, ib lub qhov uas yuav machined ntawm ib tug kawg zeb nyob rau hauv ib tug kam rau ua tej zaum yuav tsum tau drilled los yog txawm nyob rau hauv lub tshuab dhos nyob rau hauv ib tug nruj tolerance, nce nqi installation thiab txhuas lub sij hawm.
3. Tighter tolerances tuaj yeem hloov qhov yuav tsum tau kuaj xyuas
Nco ntsoov tias thaum ntxiv kev zam rau ib feem, koj yuav tsum xav txog seb cov yam ntxwv yuav raug kuaj li cas. Yog hais tias ib tug feature nyuaj rau tshuab, nws yuav nyuaj rau ntsuas ib yam nkaus. Qee lub luag haujlwm yuav tsum muaj cov cuab yeej tshuaj xyuas tshwj xeeb, uas tuaj yeem ua rau cov nqi nce ntxiv.
4. Kev kam rau siab nyob ntawm cov khoom siv
Qhov nyuaj ntawm kev tsim ib feem rau ib qho kev kam rau siab tuaj yeem yog cov khoom siv heev. Feem ntau, cov khoom siv softer, qhov nyuaj nws yog kom tswj tau qhov kev tolerances raws li cov khoom yuav khoov thaum txiav. Cov yas xws li nylon, HDPE, thiab PEEK tej zaum yuav tsis muaj qhov nruj nruj uas cov hlau lossis txhuas ua yam tsis muaj kev txiav txim siab tshwj xeeb.
