Vibratory Polishing Machins are mass finishing machines, suitable for polishing, finishing, grinding, surface improvement.


1. Adopting the world's advanced principle of helical rolling flow, three times vibration. In order to make the work parts and roll-polishing tool rubbing with each other.

2. The multitudinous use the PEFM in the middle and small size work parts to improve efficiency 6-10 times.

3. No damage to the original shape and size of the workparts.

4. The processing vessel interior surface is lined with PU(polyurethane), avoiding direct damage to the workparts and machine body, and the working life for the machine is extended.

5. Random checking the workparts in the finishing process, easy operation. Option to choose the independent electrical box with converter..

Technical Specifications

1. Structure:

Vibratory finishing machine is composed of inertial vibrator, vessel, electrical cabinet and basement.

Inertial vibrator: This is the vibrating source of the machine, it is composed Of vibratory motor,springs 

and eccentric blocks.

Vessel: The vessel is welded of annular steel plate. It is lined with high quality wearable 

Polyurethane, to weaken the noise and the bump of work pieces on vessel.  

Electrical cabinet: Operate the machine by buttons on the control panel.

Basement: It is weld of steel, and it has springs to hold the vessel.

2. Function:

Vibratory finishing machines are suitable for deburring, descaling, edge radiusing, chamfering, 

polishing, surface improvement, pre plating finishing all types of components including fully 

machined parts in metals & plastics.

3. Working Principle

Vibratory Finishing Machine for Metal Working has a ring chamber to hold abrasives (stones) and 

work pieces. When the machine is working, it makes three- high frequency vibration. The grinding 

stones and the work pieces are rolling spirally forward and they are grinding each other during the 

rolling. This makes the work pieces deburred, chamfered, polished and clean. 

To replace the traditional clothwheel polishing, the Vibratory Finishing Machine for Metal Working can 

save a lot of spending on manpower, and lower the cost of production. It can also be matched up 

with mass production, improve and stabilize the quality of the products.
