Vibratory Finishing Machine / Working Principle of Vibro - Fin

Vibro finishing process involves rubbing of parts to be finished with suitable media ( ceramic, plastic, steel, etc) in presence of finishing compound for pre-determined time.

VIBRO-FIN vibratory finishing machine has a bowl that holds parts, media, water & finishing compound. The special vibratory motor mounted at C.G. of the system generates intense spiral motion of parts & media in the bowl. The relative motion between parts & media results in deburring, descaling, polishing etc.

VIBRO-FIN vibratory finishing machine has different options for separation of parts from media. The bowl has hot cast polyurethane lining or natural rubber lining, drain for discharge of used compound & water.

VIBRO-FIN vibratory finishing machine is available is wide range of capacities from 25 lits to 2500 lits.


SM Series Vibrofin
These machines are used when inbuilt separation is not required or it is not possible due to near size of the parts and media.

In these machines at the end of the process time parts are picked up manually from the bowl.

It is generally preferred when strong vibration intensity is required and for medium to big size parts or for heavy parts.

Technical Specification

SMA Series Vibrofin
In these machines there is in-built part-media separation arrangement.

At the end of the process cycle flapper is lowered in the bowl manually & part media mixture is carried over to the separation screen. The media will fall back in the bowl & the parts come out of the machine.

80 % to 100 % separation can be achieved depending on various parameters. This type of machines should be opted when part media separation is feasible by screening method.


Technical Specification

SPA Series Vibrofin

These machines are used when 100 % part-media separation is required.

The basic change in these machines is the spiral path inside the bowl. The part media mixture moves in spiral path from minimum to maximum level. During separation cycle flapper is inserted at the maximum level & mixture is transferred to separation screen. The spiral geometry ensures that 100 % mixture is carried to screen & hence 100 % separation.

The movement of flapper is outside media zone & it is rectangular in shape which makes it ideal for fully automatic separation using pneumatic actuation ( this can not be ensured in SMA series machines).


Technical Specification

BB Series Vibrofin

These machines are used for Steel Ball Burnishing Process.
The steel media has 5-6 times more density than that of ceramic media.So these heavy duty machines are specially designed to generate effective tumbling motion even with steel media.
In Ball Burnishing process, steel media is used for burnishing(polishing) of soft metals like brass, copper, aluminium, mild steel etc.

BB Series machines don't have part media separation arrangement. At the end of the process time parts are picked up manually.

Technical Specification

BBA Series Vibrofin

These machines are used for Steel Ball Burnishing Process

BBA Series machines have inbuilt part-media separation facility. This feature is very useful for polishing small parts in large quantity.

Technical Specification

Tub Vibrofin

Trough vibrators have rectangular tub, in conventional round vibrator longer components can not be processed conveniently.
For processing longer parts trough vibrator is an ideal solution.

For special application where part to part impingement is to be totally avoided we can provide compartments in rectangular tub.

Technical Specification

Vibro Dryer

Vibro Finishing is a wet process. Hence components coming out after processing from the machine are wet & must be dried properly or given any other suitable post treatment.
VIBRO-FIN vibro dryer is used for drying of wet components. The dryer is filled with water absorbing media like corn cob. The dryer has heating arrangement to keep corn cob warm and free from moisture.
The wet components when tumbled with warm corn cob, it get nice wiping action and Stain Free Drying is achieved. Longer process time here enhances lustre of the components.
The dryer has in built separation screen for separating drying media & components.

The dryer is provided with control panel having temp. controller.

This dryer is suitable for components where corn cob used is not getting clogged.
