Drag finishing

Drag finishing

This treatment is one of the premium processes for surface finishing.
H+K offers drag finishing especially for rounding of edges, but also for smoothing and polishing after completion of the coating process.
The workpieces are mounted in holders and then dragged at high speed in a circular motion through a container containing special granules for processing.
The edge rounding reinforces the stability of the tool edge. Both treatments prevent the formation of built-up edges and minimise frictional heat during use. Tools that are treated with the H+K drag finishing process have a significantly longer life.
