Polycrystalline Cubic Boron Nitride - PCBN INSERTS and TOOLS
GENERAL APPLICATION GUIDELINES FOR FOR PCBN INSERTS

· Use a rigid machine that is fully capable of realizing the full productive potential of PCBN inserts.

·Don't use PCBN inserts for cutting easy-to-machine materials. They are designed to cut hardened
steels, cast irons and tough superalloys.

.Keep tool overhang to a minimum.

·Use negative-rake tools whenever possible.

·Avoid side-cutting edge angles under 15 degrees.

·Use plenty of cutting fluid: Soluble oil is suitable.

·Chamfer the existing edge of the workpiece to minimize burr formation on high-temperature alloys.

·Stop the cut immediately if chatter is audible. Chatter indicates that the tool edge is dull or the setup isn't rigid enough.
