The drag-finishing process

In the drag-finishing process the workpieces are mounted on special workpiece holders. These are dragged in a circular motion at high speed through a container filled with grinding or polishing media. The high-speed motion creates high contact pressures between the workpieces and the media, producing perfect results in a very short time in the form of high-precision rounding of the edges or a high-lustre finish in a quality that can otherwise only be obtained through hand polishing.
