PCD Insert Machining Dont's #1

PCD inserts are not recommended for the machining of Iron, Cobalt, or Nickel alloys. In the presence of these metals and the heat and pressure created by cutting, diamond is encouraged to revert to the metastable carbon form: graphite. It is possible to use PCD inserts to machine some stainless steels and other highly alloyed materials, which have the iron, cobalt or nickel tied up in a non-reactive state. Even so, these materials should be machined at low cutting speeds and feeds with coolant to reduce any heat generated.


What is PCD (Polycrystalline Diamond)?
