Kev co lub cev muaj zog ua kom muaj zog centrifugal los ntawm qhov siab -kev sib hloov ceev ntawm eccentric hnyav, yog li inducing vibration hauv lub vibrating trough. Hom kev vibration ntawm lub trough feem ntau yog peb -dimensional, suav nrog ntsug kev co thiab ob lub orthogonal kab rov tav vibration Cheebtsam. Qhov no peb -qhov kev vibration ua rau kev sib tsoo thiab polishing xov xwm-nrog rau cov khoom ua haujlwm- ua raws txoj hauv kev nyuaj hauv lub trough.
Nyob rau hauv lub zog ntawm ntsug kev co, cov xov xwm thiab workpieces yog lofted mus rau ib tug tej yam qhov siab ua ntej yuav poob rov qab mus rau hauv qab ntawm lub trough nyob rau hauv lub zog ntawm lub ntiajteb txawj nqus; Meanwhile, kab rov tav vibrations induce lateral zawv zawg thiab dov motions ntawm cov xov xwm thiab workpieces nyob rau hauv lub trough. Piv txwv li, thaum lub vibrating trough oscillates raws X-axis, cov xov xwm thiab workpieces undergo alternating acceleration thiab deceleration raws li axis; tib lub sijhawm, vim kev co raws Y-axis, lawv muaj kev hloov pauv hauv Y- kev taw qhia; Tsis tas li ntawd, txoj kev vibration ntsug tsis tu ncua hloov lawv cov spatial elevation. Lub superposition ntawm peb lub Cheebtsam no ua rau cov complex, composite trajectories-xws li helical los yog ncig txoj kev.
