The classics of mass finishing technology
Circular vibratory finishing machine – ideal for a wide range of applications
From small precision workpieces to large components: whether steel, aluminium, die-cast zinc or plastic, Walther Trowal’s circular vibratory finishing machines gently finish the surface of workpieces – with maximum process reliability and minimal effort … even with complex geometries and high production volumes.
Circular vibratory finishing machines are ideal for
- Pickling, descaling, derusting
- Deburring
- Edge rounding
- Smoothing and polishing
- Cleaning and degreasing
Multi-vibratory finishing machine – circular vibratory finishing machine with Multivib drive – complements the technology for machining complex-shaped workpieces.
In circular vibratory finishing machines, the relative movement between the workpieces and the abrasive media is achieved in two ways: either the parts circulate within the working chamber together with the abrasive media, or they are fixed in place within it and the abrasive media flows around them.
Traditional circular vibratory finishing machines feature a ring-shaped working chamber which is filled with the workpieces and abrasive media. It is set into vibration by unbalanced motors in such a way that the workpieces move in a spiral pattern within the abrasive media. This creates the relative motion that results in material being gently removed.
In multi-vibratory finishing machines and TX finishers, the workpieces are clamped into the working chamber. This ensures that the relative movement is particularly intense; furthermore, the workpieces do not come into contact with one another. This broadens the range of possibilities to include parts with complex shapes and very delicate surfaces.
After machining, the abrasive media are separated from the workpieces in the screening zone and returned to the working tank. Only the workpieces leave the system – an important consideration, particularly in automated, interlinked processes, as Abrasive media must not enter the subsequent process and workpieces from different batches must not be mixed.
