Thaj chaw ntawm qhov chais CNC yog ib qho kev mob tshwm sim los ntawm ntau yam cuab yeej uas txhais tau tias nws muaj peev xwm, siv tsis tas tshaj tawm, nyob deb, thiab lub sijhawm tswj hwm. Nws tsis yog ib leeg leeg, tab sis yog ib qho tshwm sim uas tuaj yeem sib txawv ntau dua ib zaug nyob rau hauv cov cai. Cov cuab yeej tseem ceeb yog lub teeb kub thiab lub teeb kub (X, Y, Z) uas tig txeem, uas sib piv nrog tus naj npawb ntawm khoom siv thiab kev pab cuam tiv thaiv. Qhov chaw spindle yog ib qho ntxiv ntau ntxiv; ib qho chaw spindle tsawg kuj tuaj yeem raug rau hauv qhov kev ua haujlwm tshwj tsis, tab sis high-speed, high-torque lossis geared-head spindles rau kev siv tshwj tsis yuav tsum muaj ntau ntxiv. Lub CNC control unit tus leej li, los ntawm cov xaiv zoo li Fanuc, Siemens lossis Heidenhain, yog ib qho ntau ntxiv hauv thaj chaw, uas muaj cov rooj sib tov zoo li high-speed processing, sophisticated look-ahead, thiab complex kinematic transformations rau 5-axis work. Cov kev pab tiv thaiv yuav cuam tshuam ntau rau thaj chaw. Ib qho tshwj xyuas tshwj xyuas yog standard, tab sis qhov capacity thiab speed sib txawv. Qhov ntxiv ntawm ib qho kev tshawb nrhiav, tool breakage detection lossis tshaj tawm ib qho pallet changer rau kev tswj tsis tas tshaj tawm, tuaj yeem ntxiv ob tug rau thaj chaw. Lwm yam cuab yeej tseem ceeb yog qhov zoo ntawm qhov chaw (xample: polymer concrete rau superior damping), hom ntawm guideways (linear guides vs. more rigid box ways), kev ntxiv ntawm thermal compensation systems, thiab lub npe ntawm tus neeg tsim. Yog li no, "thaj chaw" yuav tsum raug sau ua ib qho kev lag luam, suav nrog thaj chaw thawj nap thiab kev ntxig ntxag hauv kev ua haujlwm, accuracy, reliability, thiab kev kho kom tsawg dua, uas sib pab tiv thaiv qhov thaj chaw tseem ceeb.
