1. Nws yog ib qho yooj yim los xyuas kom meej qhov tseeb ntawm txhua qhov chaw ntawm lub workpiece; Thaum lub sij hawm ua, lub workpiece rotates nyob ib ncig ntawm ib tug ruaj axis, thiab txhua qhov chaw muaj tib lub axis ntawm kev sib hloov, yog li nws yog ib qho yooj yim los xyuas kom meej lub coaxiality ntawm cov ua nto;
2. Cov txheej txheem txiav yog qhov ruaj khov; tshwj tsis yog rau qhov cuam tshuam ntawm qhov chaw, cov txheej txheem tshuab dhos tshuab feem ntau tsis tu ncua, tsis zoo li milling thiab kev npaj, nyob rau hauv tus txheej txheem ntawm ib qho dhau, cov hniav cutter raug txiav hauv thiab tawm ntau zaus, ua rau poob siab;
3. Nws tsim nyog rau kev ua tiav ntawm cov khoom tsis yog -ferrous hlau; rau qee qhov tsis yog -ferrous hlau qhov chaw, vim qhov tsis tshua muaj hardness thiab zoo plasticity ntawm cov khoom nws tus kheej, nws yog ib qho nyuaj kom tau ib tug du nto los ntawm lwm yam kev ua;
4. Cov cuab yeej yooj yim; Cov cuab yeej tig yog qhov yooj yim tshaj plaws ntawm cov cuab yeej, thiab nws yooj yim heev rau kev tsim khoom, ua kom pom tseeb thiab nruab, uas ua rau nws yooj yim los xaiv lub kaum sab xis tsim nyog raws li kev ua haujlwm tshwj xeeb.
