Working Principle

Chenwei Series Vibration Polishing Machine has a ring chamber to hold media (abrasive stones) and work pieces.When the machine start working,it makes three-D high frequency vibration.This motion makes the media work on surface of work pieces upward &downward;leftward and rightward;frontward and backward.The process is similar to handwork of surface polishing.

The grinding stones are rolling forward and they are grinding each other during .this makes the work pieces ,polished and clean.

To replace the traditional cloth-wheel 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.

The machine structure

Vibratory Polish 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 workpieces on vessel. (For CWP series, there is a separator on the vessel to seperate the workpieces from the stones. )
