Edge preparation – The key to success

To be really successful in any metal cutting application, it is of outmost importance to control the cutting forces and the material flow. This is of course also valid for PCBN cutting tools. In turning, the rotation of the work piece generates a tangential force, Ft, on the cutting edge and the feed generates a radial force, Fr, on the cutting edge. These two forces added together, generates a resultant force which must be taken care of by the edge preparation.

If the radial or the tangential force is too big, top flaking or edge breakage will occur. By choosing inserts with a proper edge preparation, the resultant force can be taken care of and be directed into the centre of the insert. The optimized edge preparation gives a cutting edge as strong as possible, but still as sharp as possible which together with optimized cutting data generates a controlled wear pattern and long tool life.

Our long experience within the PCBN area has resulted in a wide product portfolio, suitable for many different application areas. It is of course not optimized for every unique application, but it always gives a good start. For full optimization, do not hesitate to contact the PCBN product specialists for support.
