Four outer brushes (15) can be mounted round a single inner one (14), their polishing areas overlapping. Each brush can have a rotary spindle, on which several polishing tools are mounted, and each spindle can be driven by V-belt from a motor. Hot air can be supplied to each polishing unit, these being of different diameters and accessible via an opening in the housing. A polishing wheel for cutlery can protrude from the housing, being mounted on a separate motor-driven spindle.
