Vibratory Finishing


Vibratory Finishing Machines are mass finishing machines, used for deburring, polishing, descaling, and surface improvement on metal and plastic components.

Working Principle

The machine has a steel bowl lined with rubber or polyurethane which is filled up with required media (either ceramic, plastic, maize etc. depending upon the finish required) and components. Eccentric weights are mounted on an extended shaft attached to a heavy duty motor to cause vibrations and create a spiral of the media and the components. Variations in vibration, achieved by varying weights and angles, and suitable combination of media enable machine to be used for different components.

Standard Features:

  • Effective motor position for Superior Vibration.
  • High tensile nut bolts for longer machine life.
  • Efficient removal of process fluid for best surface finish.
  • Energy efficient motor.
  • Bowls shot blasted before and after Polyurethane lining for painting.
  • All internal welds ground smooth.
  • Anti rotation motor locking plate provided.
  • Bowls are stress relieved

Additional Features:

  • Complete Polyurethane lined bowl including separation area.
  • Complete Polyurethane dam flap to avoid metal contact instead of metal flap.
  • Polyurethane corrosion resistant paint for longer life in acidic /alkaline environments.
  • Accident proof media outlet design for total safety.

  • Can handle very small to large parts.Batch or continuous operation.
  • In-Process Inspection.
  • Integral separation.
  • Better media/parts mixing since it has cascade and circular action.
  • Economical for general purpose work, heavy deburring, continuous processing, and continuous inspection.
  • Full automation capability.
  • Batch or continuous operation.

Spirotech MachineSpirotech Machine (Curved walls)

Spirotech machines have curved bowls that allow larger batch loads and reduced process time. Recommended for light and small components. Which in standard machine, tend to float on the outer periphery of the bowl.

These machines are available with or without separation for Model 120L and above.

Vibratory Finishing Machine with Superior Separation

Certain applications require that each and every component is separated from media. It is possible to achieve this with machines that are specially designed to suit the geometry of the components and media.

These machines are provided with a hump for superior separation of parts from media with specially designed screens. We custom make these screens based on your part sizes and media chosen for your process. It is possible to automate the entire finishing process.

VFM 300Superior Separation

The machine works on principles of vibration technology. Energy in the form of vibratory forces is imparted from the machine’s drive system to the mass of media and then to surfaces of the parts throughout the entire load. Vibratory motion is induced by an eccentric weight system mounted on a drive mechanism.

The bowl has no end walls, which permits a continuous circular flow of media & parts. Adjusting the degree of eccentricity (amplitude), No. of auxiliary plate on the main eccentric weights and/or the drive speed (frequency) causes media component mixture to follow the contours of bowl in a rolling & tilting type of movement resulting in finishing operation on componets.

At the completion of process cycle a dam is inserted in the work load mass to elevate the parts & media mixture on separation screen. As the mixture flows over the separation screen, the media will fall through the screen back into bowl while parts are directed into receiving container.

Special Features:

  • Continuously welded and stress relieved MS bowl, lined with POLYURETHANE.
  • Specially designed heavy duty motor generating high centrifugal force
  • Inbuilt separation on component & media
  • Optional: Pneumatic cylinder for dam insertion, Control console with PLC, Variable speed drive, Automatic component loading arrangement, Component dryer.


  • Unidirectional processing & Separation / Unloading : No need to stop the machine & reverse the direction for separation of media & unloading of component.
  • Improved separation efficiency up to 95%
  • Ideal for delicate parts processing.
  • Easy separation


  • De burring
