LZGC/LZGS Spiral Vibratory Finishing Machines with a built in spiral  ramp bowl (LZGS series) or a helical geometry bowl (LZGC series allow a damage free processing of delicate components )  and separator screen inside, when the completion of processing, a flap is operated either manually or pneumatically, for automatic separation, media and components are delivered over the separation screen and the media returns through the screen to the bowl and components discharge to a collect bin or secondary operation. This series machines are suited for the processing of high production, small components, or flat, lightweight parts which easy stick together. They are also suitable for steel ball burnishing processing.

PLZG/PLZGC Circular Vibratory Finishing Machines without internal media/parts separation screen for optimum processing capacity, suitable for processing delicate medium/large components which easy damaged by dam and separation screen, or for a variety of parts of different sizes and batches, where automatic unloading does not have any particular advantage.
