PCD remers are used extensively for high volume machining of aluminum and non-ferrous metals. The automotive industry uses PCD tooling for maching almost all their non-ferrous parts such as engines, transmissions, wheels, and brakes.

Advantages:

1.      superior finish part surface quality

2.      exceptional finish hole size and tolorance results

3.      higher production rates

4.      extremely high tool life

PCD tipped tools consist of a carbide body with a PCD (polycrystalline diamond) insert brazed to the cutting portion of the tool.

 

The PCD insert can withstand abrasion wear and heat degradation to a higher extent than carbide or coated carbide. Due to the cost of PCD, a small segment is fixed to a portion of the cutting tool that is engaged in actual chip formation. PCD tools that are constructed with a brazed insert are sometimes referred to as " fixed pocket" tools.
