Cov ntsiab lus tseem ceeb ntawm kev tsim cov khoom sib xyaw
(1) Yuav tsum muaj ib qho (lossis ob peb) convex thiab concave tuag nyob rau hauv cov khoom sib xyaw, thiab cov convex thiab concave tuag yog qhov tseem ceeb ntawm cov khoom sib xyaw. Lub precision ntawm xuas nrig ntaus qhov chaw yog siab dua li ntawm ib tug txheej txheem, thiab cov precision ntawm xuas nrig ntaus qhov chaw tuaj yeem ncav cuag IT10 ~ IT11.
(2) composite tuag tawm ntawm qhov chaw raug thawb tawm los ntawm pwm lub qhov ncauj, qhov chaw yog tus du.
(3) Lub tshuab xuas nrig ntaus ntawm cov khoom sib xyaw ua ke yog qhov nyuaj dua, thiab ntau yam txheej txheem tau teeb tsa nyob ib puag ncig ntawm qhov chaw ua haujlwm ntawm qhov tuag, yog li qhov kev kaw qhov siab feem ntau siab, tshwj xeeb tshaj yog nyob rau hauv kev tsim yuav tsum tau them sai sai rau.
(4) Tus nqi ntawm cov khoom sib xyaw yog siab, lub voj voog tsim tau ntev, thiab nws feem ntau tsim nyog rau kev tsim khoom ntawm ntau qhov chaw stamping.
(5) Thaum tsim cov khoom sib xyaw, xyuas kom lub zog ntawm cov tuag, tshwj xeeb tshaj yog them rau qhov tsawg kawg nkaus phab ntsa thickness ntawm cov tuag. Txhawm rau ua kom lub zog ntawm cov tuag thiab txo qhov kev nthuav dav ntawm cov khib nyiab hauv lub qhov, nws tuaj yeem siv los ua kom cov phab ntsa thickness nyob rau hauv qhov zoo ntawm kev txiav ntug ntawm qhov tuag thiab thawb cov khib nyiab tawm hauv qhov rov qab.
(6) Muaj ntau hom kev thawb cov cuab yeej ntawm cov khoom sib xyaw. Hauv kev tsim, kev saib xyuas yuav tsum tau them nyiaj rau qhov kev ua haujlwm ntawm lub phaj thiab qhov thaiv, thiab qhov nyiaj ntawm qhov kev ua haujlwm ntawm ob yuav tsum zoo ib yam. Nyob rau hauv lub xeev qhib ntawm pwm, lub thaiv yuav tsum nthuav tawm lub concave tuag 0.2 ~ 0.5mm.
(7) Muaj ntau hom kev tuag kov tsim nyog rau kev sib xyaw tuag, xws li hom xovxwm, hom ntsia hlau, hom flange, hom ntab, thiab lwm yam tuaj yeem xaiv. Nws yuav tsum tau ua kom ntseeg tau tias tus kov tuag yog haum zoo tom qab thauj khoom rau hauv lub rooj zaum tuag thiab muaj kev ruaj ntseg txaus. Nws tsis tuaj yeem txo lub zog ntawm qhov tuag tes tuag vim qhov teeb tsa ntawm cov khoom siv rov qab los, lossis nce qhov siab kaw ntawm qhov tuag ntau dhau.
