CNC milling tau suav tias yog ib qho ntawm cov kev siv siv dav tshaj plaws hauv machining. Hauv hnab tshos milling cov khoom hauv ib qho kev txiav txim siab kaw ntawm ib qho chaw tiaj ntawm daim ntawv ua haujlwm raug tshem tawm rau qhov tob ruaj khov. Firstly roughing kev ua haujlwm yog ua tiav kom tshem tawm cov loj ntawm cov khoom thiab tom qab ntawd hnab tshos tiav los ntawm kev ua tiav ntev zeb. Feem ntau ntawm cov kev lag luam kev lag luam milling tau txais kev saib xyuas los ntawm 2.5 axis CNC milling. Txoj kev ntawm txoj kev tswj no tuaj yeem siv tshuab li 80% ntawm txhua qhov chaw siv tshuab. Txij li qhov tseem ceeb ntawm Pocket Milling yog qhov muaj feem xyuam, yog li kev ua kom zoo rau cov hnab tshos tuaj yeem ua rau lub sijhawm siv rov qab thiab raug nqi.
Feem ntau cnc milling tshuab (tseem hu ua machining chaw) yog lub computer tswj cov ceg uas muaj peev xwm txav lub spindle ntsug raws z-axis. Qhov kev ywj pheej ntxiv ntawm kev ywj pheej tso cai rau lawv siv hauv diesinking, engraving appss, thiab 2.5d tej ntaub ntawv xws li kev nyem ntsej muag. Thaum ua ke nrog kev siv cov cuab yeej conical los yog pob tw ntswg cutter, nws tseem txhim kho cov kev ceev, muab cov nqi them rau feem ntau-ua haujlwm.
