Nyob rau hauv tus txheej txheem ntawm loj-scale machining ntau lawm, cov txheej txheem uas ncaj qha cuam tshuam rau kev hloov ntawm raw cov ntaub ntawv rau hauv cov khoom yog hu ua txheej txheem txheej txheem, uas zoo muaj xws li dawb paug manufacturing, qhov chaw ua, kev kho cua sov, zoo soj ntsuam thiab tshuab dhos rau ib tug tej yam kev mob. . Txhawm rau kom ntseeg tau tias cov txheej txheem ib txwm muaj, kev tsim cov cuab yeej thiab cov khoom siv, thiab kev hloov kho thiab kev saib xyuas cov cuab yeej siv tshuab yog cov txheej txheem pabcuam.
Cov kws tshaj lij machining loj yuav tsum tau txiav txim siab cov txheej txheem yuav tsum tau txais thaum lub sijhawm ua haujlwm raws li qhov ntau ntawm lawv cov khoom, cov khoom siv thiab cov neeg ua haujlwm zoo, thiab yuav sau cov ntsiab lus cuam tshuam rau hauv cov ntaub ntawv txheej txheem, uas yog hu ua cov txheej txheem kev cai. Txhawm rau ua kom yooj yim rau kev npaj, ua tiav thiab tsim cov koom haum tswj kev tswj cov txheej txheem, nws yog ib qho tsim nyog yuav tsum tau faib cov txheej txheem mus rau ntau theem ntawm cov chav nyob.
Loj scale machining yog cov txheej txheem, installation, chaw nres tsheb, kauj ruam thiab dhau. Cov txheej txheem yog lub hauv paus chav nyob hauv cov txheej txheem. Cov txheej txheem machining ntawm qhov chaw muaj ntau yam txheej txheem. Cov txheej txheem yuav suav nrog ib lossis ntau qhov kev teeb tsa, txhua qhov kev teeb tsa yuav suav nrog ib lossis ntau qhov chaw nres tsheb, txhua qhov chaw nres tsheb yuav suav nrog ib lossis ob peb kauj ruam, thiab txhua kauj ruam yuav suav nrog ib lossis ob peb kis.
