Stream finishing machines

SF technology, also known as stream finishing, gives rise to an innovative new generation of mass finishing machines. In this process, the workpieces are clamped in a holder and lowered into a rotating container filled with a grinding or polishing medium. The actual finishing motion is generated…

Drag finishing machine

In the drag finishing process, the workpieces are clamped in specially designed holders. These holders are dragged in a circular motion through a process drum containing grinding or polishing granualate. This high-speed motion generates high contact pressure between the workpiece and the media,…
