CNC, tseem hu ua CNC milling tshuab, yog ib lub sij hawm Ameslikas los ntawm Hong Kong uas yog tom qab qhia rau lub Pearl River Delta cheeb tsam ntawm mainland Tuam Tshoj. Qhov tseem ceeb, nws hais txog lub tshuab CNC milling. Hauv thaj chaw Guangdong, Jiangsu, Zhejiang, thiab Shanghai, qee zaum hu ua "CNC machining center." Nws yog hom machining thev naus laus zis, tus txheej txheem tshiab uas lub luag haujlwm tseem ceeb yog programming cov txheej txheem machining- hloov cov ntawv ua haujlwm rau hauv computer programming. Tau kawg, kev paub ua ntej hauv phau ntawv machining yog yuav tsum tau.
