They work according to the vibratory finishing process and also give filigree parts with complex inner structures any desired surface structure, be it a high-gloss polish or defined roughness values.

With its three controllable, high-frequency unbalance drives, the multivibrator generates complex flow patterns, whereby connecting the workpiece to the work bowl enables the flow of abrasive particles through internal structures. At the same time, the high-frequency vibration with a small amplitude protects the edges of the workpiece.

With the choice of suitable abrasives and chemical compounds, Walther Trowal adapts the entire vibratory finishing process to the requirements of additive manufacturing.

After the first applications were initially realised in the high-end sector - in motor sports, aerospace and aerospace technology and medical technology, the multivibrator now has a high degree of flexibility due to the automatic, synchronous automatic, synchronous processing of several parts, the multivibrator has great potential for the mass production of additively manufactured parts
