Edge rounding
Edge rounding is a special process for the surface treatment of workpieces . The workpieces to be processed, primarily metal , are rounded off by a special brushing process (different depending on the machine manufacturer).
Areas of application
The edge rounding is used in the metal as well as in the plastic and wood processing industries. In the metal industry, the edge rounding z. B. sharp edges removed to avoid injuries to the end user . When processing wood into pieces of furniture , the rounded edges are important for the paint to hold . However, edge rounding is particularly important for cutting tools . A defined cutting edge rounding can extend the service life of cutting tools.
Precision edge rounding
The precision edge rounding (also flak marking ) is a further development of the edge rounding. Brush tools are also used, which achieve accuracies in the μ range for edge rounding and in the nano range for surface polishing. Precision edge rounding has many areas of application. It is also used (as with normal edge rounding) to extend the service life of cutting tools many times over. However, it is also used to flak hard metal indexable inserts, drills, milling machines, saws and punched parts.
development
Flak listing was developed in 2003 by Profin Progressive Finishing AG in Switzerland based on customer requests. The first machine at that time, the FLAKKO, gave this machining method its nickname.
