Container of 6 litre. With wet grinding, the workpieces move through the process container in a toroidal current. The difference in mass between the workpieces and the plastic abrasive causes material to be removed and this is then washed away by the water/compound mixture. This eliminates the need for tiresome and time-consuming manual processing and achieves results after about only 3 – 4 hours: - Complete removal of abrasion scratches and casting skin - Clean and bright workpiece surfaces The soft binder of the abrasive prevents the surface from hardening and forming becoming pitted.If you are interested in buying this container, you also need this machine H469203 Eco-Maxi Basic Unit
