What Is a Vibratory Finishing Machine?

Vibratory finishing is an important process for a wide variety of products, including metal parts and plastic components. The vibratory motion created by the vibratory motor results in material removal from workpiece edges. The vibratory motion is induced by an offset mass on the bottom of the processing bowl, which is supported on fairly stiff springs. The relative motion between the media and workpieces causes the removal of material, resulting in the desired isotropic surface finish.

Typically, vibratory finishing machine use one of two types of media: ceramic or plastic. Ceramic media has a high density and is tough, so it’s a great choice for deburring and polishing hard metal parts. Plastic media, on the other hand, is more pliable and can be moulded into a specific size. The plastic media is ideal for finishing nonferrous parts and is less expensive per running hour. Ceramic media can chip easily if excessive force is applied to it, so it’s not the ideal option for polishing and deburring ferrous metal parts.

Vibratory finishing machines typically contain a bowl and a control box. The motor is attached to a wire on the bottom of the container and connected to an electrical source in the factory. The wires are usually yellow/green and connected to a ground wire. While operating a vibratory finishing machine, pay close attention to the parts and media in the tub.
