Vibratory finishing

Vibratory finishing is a surface finishing process that uses a vibrating tub filled with abrasive media, such as triangular ceramic or conical plastic impregnated with aluminum oxide, to mechanically scrub and remove contamination, paint, tape, corrosion products, and soil from almost any type of item. This process can be used on most metals and alloys, ceramics, glass, and plastic parts. Vibratory finishing is commonly used in mass manufacturing of hydraulic, wind power, and aerospace components.From: Hazardous and Radioactive Waste Treatment Technologies Handbook [2019], Micromachining of Engineering Materials [2019], Advanced polishing, grinding and finishing processes for various manufacturing applications: a review [2020]

Vibratory finishing utilizes a rotating, eccentric weight system that dynamically oscillates an attached open- topped tub or bowl mounted on springs. Most machines employ an adjustable eccentric weight system, shown in Figure 1.16 as the squares above the center shaft to the right and left. By adding or removing weights the amount of vibrational energy available in an individual finishing operation can be adjusted. The vibrating action of the bowl causes the workload — the media and part(s) —to “flow” around the bowl in a twisting toroidal path. Figure 1.17 captures the vibratory bowl finisher in operation.
