Vibratory finishing is a technology that is mainly employed for the surface treatment of metal components. But vibratory finishing processes can also be used for finishing the surface of parts made from plastic, wood, glass and various types of stone.
Together with grinding or polishing media made from ceramic, plastic or metal as well as chemical additives (usually called compounds) the parts to be finished are placed in a vibratory work bowl that is lined with polyurethane. A vibratory motor is inducing an oscillating or rotary movement of the vibratory of parts and media in the work bowl. The constant rubbing action between media and parts causes the desired removal of material from the parts. Different combinations of grinding or polishing media and compounds allow practically infinite variations of surface finishes on the processed parts.
Normally, vibratory finishing is a so-called batch process: The movement of the work pieces and the grinding or polishing media in the vibratory bowl takes place for a pre-determined, fixed cycle time. But the development of various types of separation and material handling systems and different versions of work bowls now allows running vibratory finishing processes not only in batch but also continuous mode. Frequently, by linking multiple equipment components the vibratory finishing process can be run fully automatically without any manual intervention.
At Rosler vibratory finishing is used for the following surface finishing processes:
