Tub finishers, or trough vibrators, are a versatile finishing machine for medium to large parts. For their capacity, tub finishers provide the maximum channel width and allow parts to be easily segregated with customizable, removable compartment dividers. The heavy-duty, interlocking structural design of our tub finishers feature a U-shaped trough that is lined with a premium polyurethane lining that is then mounted onto coated coil springs.
