The Method of Vibratory Finishing

vibro machines

In vibratory finishing equipment, materials go into a bowl or tub, and the entire load shakes all at once. This movement causes the media to rotate or move up and down within a tub. The parts and media rub against each other to achieve the surface finishing objective. The friction in a vibratory system occurs with every pulse of vibration. Vibratory finishing works best for large and small parts in order to create a smoother finish.

What is a Vibratory Machine?

A vibratory tumbler, trough or bowl is the equipment used in a vibratory finishing process and is one of the most common methods in mass finishing. This finishing process is to clean, deburr, descale and polish workpieces. It can also be used as a surface preparation step to enhance the bonding of coating, plating, and adhesive materials to the workpiece. The process of a vibratory tumbler involves placing workpieces and parts inside a tub filled with shaped pellets of media and then applying a vibration force to all the tub´s contents. Sufficient vibration force is applied by the motor. During the process, a finishing chemical can be added to the tub.

The machine vibrates and rotates causing the media to rub against metal parts. The friction from the media and metals removes imperfections, scales or rust, and polishes the metal. The barrel grinds with greater force than a vibratory finishing machine. In Barrel tumblers, the deburring only happens in the slide area of the barrel.

Types of Finishing Media

Media is the hard ingredient added into the tumbler to prevent parts from just banging together. Different media has different properties.

  • Steel Media: heavy deburring, shining, polishing, and burnishing metal, plastic, or ceramic parts.
  • Plastic Media: great at finishing delicate parts in a process that does not involve excess wearing of work parts. Used for general metal deburring, precision deburring, polishing and burnishing. This type of media is used on softer metals such as aluminium or brass and on threaded parts.
  • Ceramic Media: used for heavy, light and when fast deburring is needed. This type of media is good for heavy, and hard metals such as steel, and to remove rust on parts. Also used for general purpose polishing. Plastic, steel, stainless steel and aluminium parts are often polished using ceramic media.
  • Organic Media: walnut shells can be used for medium to light deburring and for light finishing and polishing. Corn cob is used when finishing some metal parts because of its ability to absorb surface oils on the parts. Organic media is the natural, and safer way for the environment as they are biodegradable, durable and reusable.

Size and Shape of Media

From cylinders and balls to pyramids and sharp-edged stars, finishing media comes in many varieties. The shape of the parts being finished will determine the shape and size needed for finishing media.

  • Round, oval and cylindrical: preferred for general use, and have lower chipping rates.
  • Triangles, arrowheads and Tri-Star shapes: great for finishing complex parts with hard-to-reach sections. They also have a higher wear rate and are more susceptible to chipping.
  •  Small media: has more contact with the component surface area than larger materials and produces a smoother, more attractive surface. Production times are longer for small media polishing.
  • Large media: Lends itself to aggressive grinding. Provides rapid removal of burs and is also effective for sharp edges.

Types of Vibratory Finishing Equipment

  • Vibratory Circular Bowls: Designed to process small to medium sized components 
  • Vibratory Troughs: Designed to process long and delicate components 
  • Maize Dryers: Excellent drying abilities and heating system 
  • Centrifugal Disc Finishers: Designed to aggressively process small robust components, it has a short process time of deburring polishing of small and medium work pieces. 
  • Centrifugal Dryers: Drying metal and plastic arts by centrifugal force & hot air 
  • Floor Separation Units: Floor mounted vibration decks with interchangeable screens 
  • Bench Top Vibratory Bowls: Suitable for processing small batches

Benefits of Vibratory Finishing

  • Vibratory systems produce a smoother finish as their action is more like filing and they do it more quickly.
  • A vibratory finishing machine can cut inside a metal part and reach every area the selected media can get into.
  • The system can be automatic as they are better for big and delicate parts; this reduces labour costs
  • A better option for finishing very large or delicate parts.
  • Produce finer results with less wear on parts.
  • Increases durability and lifespan of the part.
