Discover how ActOn Finishing’s vibratory machinery works, from troughs and bowls to dual machines and dryers, by reading our latest blog.

The manufacturing process of vibratory finishing is often used to deburr, descale, burnish, clean and brighten parts for a variety of industries.

In comparison to tumblers, vibratory machinery is a lot quicker, quieter and at ActOn Finishing, our machines can also be customised to suit customer requirements.

But how does vibratory machinery actually work? We take a closer look at the process behind four machines in our Vibrota Range.

Vibratory Bowls

Our Vibratory Bowls are simple to operate and highly efficient, coming in classic designs and sizes to meet your unique applications. They are built to suit customer applications, from deburring and descaling, radiusing, cleaning and polishing or surface improvement.

The design of the Process Chamber in the Vibratory Bowls ensures components are subjected to effective tumbling action, resulting in shorter process times.

Each of the Bowls are equipped with a separation system, which can be engaged manually or pneumatically to form a bridge that assists parts to travel onto the separation screen whilst the vibratory machinery is still vibrating. The media is then screened through the screen and retained in the bowl whilst the parts exist from the machine.

Vibratory Troughs

ActOn Finishing offers Troughs in many different sizes and an infinite choice of length and width combinations, making them one of our most versatile ranges. Several processing chambers can be made with use of dividers and the Troughs can be customised to suit user applications.

Similar to our Bowls, Vibratory Troughs use a process chamber to ensure components are subjected to effective tumbling action. The work chamber in the drive system has a powerful, heavy-duty extended shaft with a foot mounted vibratory motor fitted on it to imart powerful and uniform vibrations to the mass in the trough.

Due to these vibrations, the mass moves along a linear and spiral path inside the work chamber ensures the media is continuously in contact with the components resulting in effective processing in the shortest time.

Dual Machine

The orbital Dual finisher works to both deburr and dry in one single unit, with the option to carry out both wet and dry processes in one machine. The design integrates two process chambers: an inner chamber that can be used for wet process application, and the outer chamber for dry process applications, both of which make it easier to control.

The inner chamber has a hot cured polyurethane lining and can be used from deburring, descaling, radiusing and cleaning to polishing and surface
Improvement. The heated outer chamber can be used for drying/cleaning the parts after being processed in the inner chamber, and parts can automatically be transferred from the inner chamber to the outer chamber.

There’s also our unique, elliptical-shaped Vibratory bowl drying machines, built to suit a variety of finishing needs. Compact in size and simple to operate, ActOn Finishing’s dryers are known for their 100% separation of parts and can be used as a batch process or single lpa continuous process applications.

To dry parts, the heat is force convected by an air circulating fan motor. Components that need to be dried are loaded on the metal conveyor belt, which travels through the heated drying chamber and collected at the discharge end.

At the heart of the machine is the vibratory motor, in the work bowl. Releasing uniform vibrations to the mass in the bowl, the mass moves along a rotary and spiral path ensures continuous contact with components. Special castings and bearings form the assembly of these motors, making them mechanically robust and reliable.

What is a vibratory finishing machine?

As a common finishing method in the manufacturing industry, vibratory finishing is an efficient process used to optimise all types of small products and parts. Vibratory finishing machines help you clean and deburr products at a faster pace.

What is vibratory deburring?  

Vibratory deburring removes the rough edges from parts and enables them to fit together more efficiently. This leads to fewer part rejections as well as improved safety. In addition, deburring is an important step in preparing parts for painting.

How does vibratory polishing work?

In this stage a combination of media, parts and compounds are placed in a vibrating machine. The vibrations cause the contents to move in a circular motion and the media to grind against the part to get the desired finish.

What is a tumbling barrel?

Barrel finishing, also known as barrel tumbling or vibratory finishing, is a surface improving operation in which a mixture of parts, media and compounds are placed in a six- or eight-sided barrel and rotated at a predetermined speed for the purpose of rounding corners, deburring, grinding, descaling, deflashing, improving surface finish and much more. 

What are the different types of finishing?

There are several types of metal finishing such as metal plating, chemical finishing or coating, grinding, buffing, electroplating, and sandblasting. Each process has basic steps with all processes beginning with surface preparation. Metal finishing processes can include anything from technical processes to buffers.
