What is vibratory finishing and how does it work?
Mass finishing, also known as barrel finishing, is based on a natural principle. Similar to how sand and water grind coarse rocks into smooth pebbles in nature, modern production technology gives workpieces the desired surface. By using specialised machines, abrasives, compounds and water, we achieve precise and desired surface finishes. Compared to manual processing methods, vibratory finishing offers numerous advantages: It enables reproducible results and more economical manufacturing processes.

The application areas of mass finishing technology
Today, vibratory finishing is a widespread mechanical-chemical manufacturing process that is used in various areas of application, including:
- Deburring and rounding of edges: Vibratory finishing ensures clean and precise edges, free of burrs and sharp transitions.
- Smoothing and polishing: Fine tuning of the sanding process allows surfaces to be polished to a mirror finish.
- Cleaning and degreasing: In addition to surface finishing, vibratory finishing also enables effective cleaning and degreasing of workpieces.
- Descaling and derusting: Even stubborn oxidation layers such as scale and rust can be efficiently removed using mass finishing technology.
Vibratory finishing is suitable for workpieces made from all common metals and metal alloys. The technology can also be used for moulded parts made of rubber, plastic or ceramics, making it a versatile solution for a wide range of industries. By using mass finishing technology in your production, you can not only increase the quality and aesthetics of your products, but also significantly improve the efficiency of your manufacturing processes. Discover how mass finishing technology can also support your production goals.
The advantages of the mass finishing process at Walther Trowal
The mass finishing process offers numerous advantages over traditional machining methods. It is particularly efficient when machining complex or delicate parts and can process several workpieces simultaneously without monitoring. Here are some of the advantages that vibratory finishing offers:
- Uniform machining: All surfaces of the workpiece are treated evenly.
- Time efficiency: Simultaneous processing of several parts saves time.
- Flexibility: Different media and intensities allow for a wide range of finishes.
- Cost efficiency: Reduces manual labour and increases throughput times.

Trough vibrators
If your workpieces are too large for circular vibrators, simply process them individually in the trough. Sensitive parts can be secured or processed in separate chambers.

Continuous units
Our continuous units can be installed to continuously process your workpieces in the production process. The individual parts are added to the mass finishing machine in cycles, without interrupting the process.

AV unit
Centrifugal disc finishing units
Centrifugal disc finishing units have an abrasive action that is ten times stronger than that of circular vibrators. This helps remove heavy burrs and round off edges on small and medium workpieces.
to overview
Circular vibrators
From deburring and rounding to high-gloss polishing, circular vibrators can be used anywhere.

Consumables for mass finishing machines
The right combination of process media can ensure the perfect processing results. Ceramic and plastic abrasive media, combined with compounds and special media, create the ideal surface.

Drums and rotating barrels
Drums and rotating barrels are the cost-effective solution for processing small workpieces – such as those in precision mechanics – in small and medium batch sizes. They are also suitable for fine finishing and polishing.

Dryers
After mass finishing, workpieces are generally wet or moist and must be dried. This is done using either a heated drying medium or hot air, depending on your individual needs.

Accessories
Our wide range of accessories can help you adjust circular vibrators, trough vibrators, continuous units and all other processing systems to your individual requirements, and help you improve your processes.

Wastewater treatment: Innovative solutions for surface technology
Effective and efficient, reusing process water (a mixture of water and compound) and feeding it back into circulation during mass finishing can help you both save costs and protect the environment.

Drag finishers
High-value, delicate work pieces with complex shapes or work pieces made from tough, difficult to machine materials are mounted to special fixtures and dragged through a stationary bed of grinding or polishing media. Since the work pieces never touch each other during the process, they cannot scratch or nick each other.
