Lub chaw machining feem ntau tuaj yeem muab faib ua ob ntu: cov cuab yeej siv tshuab (mechanical part) thiab tswj qhov system (qhov hluav taws xob). Lub tshuab cuab yeej yog lub cev tseem ceeb ntawm lub tshuab machining, thiab kev tswj xyuas yog lub hauv paus ntawm machining chaw. Lub chaw machining feem ntau muaj cov khoom siv yooj yim (txaj, workbench, kem), spindle Cheebtsam, CNC system, tsis siv neeg hloov cuab yeej thiab cov cuab yeej pabcuam.
(Cov kab lus no raug xaiv los ntawm Tshooj 2, Tshooj 2 ntawm "Machining Center Selection Guide" Basic Parts and Basic Components of the Machining Center)
3. Cov kab ke thiab kab ke
Cov kab ke thiab kab ke yog cov ntsiab lus tseem ceeb ntawm machining center. Nws yog lub cev tseem ceeb ntawm spindle lub thawv txhawb nqa thiab kev taw qhia, thiab feem ntau dais lub zog ntawm kev khoov lub sijhawm, torque, kev vibration thiab kub hloov los ntawm ob qho kev qhia ntawm lub thawv spindle.
Vim muaj qhov sib txawv ntawm cov qauv thiab kev ntxhov siab ntawm cov chaw ntsug thiab kab rov tav machining chaw, ntu ntu ntawm kab ke ntawm ntsug machining chaw feem ntau yog tsim los ua duab plaub lossis square. Qhov loj ntawm kab ke hla ntu yog loj dua, thiab sab hauv phab ntsa yog tsim los nrog ntau dua ntsug tav thiab Nplhaib tav phaj nrog siab nruj.
Lub kem ntawm kab rov tav machining chaw yog ib tug ncej-hom kab. Lub thawv spindle yog ntsia rau hauv tus ncej ntawm kem thiab txav nce thiab nqis raws li cov lus qhia rail. Hom kab no tsis tshua muaj kev cuam tshuam rau qhov tseeb tshaj li sab-mounted kem. Sab-mounted kem ua raws li lub thawv spindle. Thaum tshav kub kub, qhov kub ntawm cov kab qhia kev tsheb ciav hlau yuav siab dua li sab nraub qaum, ua rau kem khoov rov qab vim thermal deformation, cuam tshuam qhov tseeb ntawm cov lus qhia rail ntawm lub tshuab cuab yeej. Txawm hais tias thermal deformation ntawm thav duab-hom kab yog qhov kev zam, vim yog qhov sib luag ntawm cov qauv, qhov chaw nruab nrab ntawm kab tsis hloov ntau. Cov qauv no feem ntau hu ua thermally symmetric qauv.
