• This is normally carried out in a `wet' process bowl where water together with a soluble compound is introduced via a small electric pump system.
• The process bowl is filled with media (normally an abrasive filled plastic shape) and the jewelery pieces are added.
• The process time is set using the in built timer and the speed adjusted by rotating the potentiometer knob.
• Normal process time is only 2-3 hours.

• This is carried out in a `dry' process bowl where the media used is a walnut granule pre dosed with a polishing paste.
• The bowl is filled with media together with the jewelery pieces to be polished, the time and speed are set and the process started.
• Standard polishing time is one to three hours.
• The media can be used for up to 150 hours before being replaced. During processing it is refreshed every 6 - 10 hours, by the addition of a small amount of polishing paste.
