1. Nws yog cov ntaub ntawv tseem ceeb hauv kev coj ua ntau lawm
Kev npaj thiab teem sij hawm ntawm kev tsim khoom hauv lub tshuab ua haujlwm rhiav, kev ua haujlwm ntawm cov neeg ua haujlwm, kev tshuaj xyuas kev ua haujlwm zoo ntawm cov khoom, thiab kev suav cov nqi ua haujlwm yog tag nrho raws li cov txheej txheem kev cai. Txhawm rau daws cov teeb meem hauv kev tsim khoom, cov txheej txheem cov txheej txheem feem ntau yog siv los ua ib qho hauv paus. Yog tias ua raws li cov xwm txheej zoo, lub luag haujlwm ntawm txhua lub koom haum thiab cov neeg ua haujlwm yuav tsum tau txiav txim siab raws li cov txheej txheem kev cai.
2. Nws yog lub hauv paus tseem ceeb rau kev npaj ntau lawm
Thaum lub rhiav xav tsim ib feem tshiab, nws yuav tsum xub tsim cov txheej txheem machining specification ntawm ib feem, thiab ces npaj rau ntau lawm raws li cov txheej txheem specification.
Xws li: kev tsom xam thiab kev tshawb fawb ntawm cov txheej txheem tseem ceeb hauv kev ua cov thev naus laus zis ntawm cov khoom tshiab. Npaj cov riam, clamps, thiab cov cuab yeej ntsuas uas yuav tsum tau ua. Kev yuav khoom los yog tsim cov khoom siv raw thiab cov nyiaj rov qab tag nrho. Kev yuav khoom tshiab lossis hloov kho cov cuab yeej qub yuav tsum tau ua raws li cov txheej txheem.
