Vibratory finishing machines are perhaps the most popular mass finishing machines out there. Being cost-effective and less labor-intensive, their popularity has remained virtually intact over the years. You can use these machines to de-burr, de-scale, reduce the edges, polish, remove rust, and clean the parts.
The working principle of a vibratory finishing machine is simple. It consists of a ring chamber or a container that holds the tumbling media and the parts. As the off-center rotator starts vibrating, the tumbling media and workpieces start colliding with each other, while rolling spirally forward. As the media comes in contact with parts, their surface gets cleaned.
You can use a vibratory motor with varying frequencies ranging from 900 to 3,600 cycles per minute (CPM) and the amplitude from 0 to 5 mm. This simple mechanism allows you to control the quality of the surface finish.
You can also use a variety of tumbling media to get the desired surface finish. In a typical setup, ceramic tumbling media is used for general finishing, while steel tumbling media is used for finishing metal parts. You can also use plastic and organic tumbling media if required.
