The working bowl of trough vibratory machine is open at the top and incorporates media outlet on the side. Dimensions of the working container are suitable for processing of long workpieces.

Vibrating motor with imbalanced weights is placed under the working bowl. Relative movement between workpieces and media enables material erosion. High amplitude and low frequency of the vibration are especially recommendable for deburring and grinding processes with grey ceramic media.

Possible processes to be run in this machine are: deburring, rounding, grinding, cleaning, deoiling, smoothing and polishing.
