Shaving Dies with Tungsten Carbide(TC) insert are widely used for shaving application. But TC shaving dies haven't performed well relatively for lifetime, the shaved surface and high-precision controlled. To use polycrystalline diamond(PCD) for shaving is a better choice. It has proven to provide a superior surface finish and improved consistency for different wire materials.

The bearing area of PCD shaving dies support shaved wire materials against the vibration, the wire surface shaved by a PCD die is much better than that shaved by a TC die.
  
The lifetime of PCD shaving dies provide 20 to 80 times (depending on materials) longer tool life than TC shaving dies. The long life reduces the setup time of exchange dies.
  
Comparison of TC Shaving Die and PCD Shaving Die
TC Shaving Die
Advantages: dies cost cheap.
Disadvantages: short lifetime, poor consistency of wire, surface defects, high temperature.

PCD Shaving Die
Advantages: long lifetime, good consistency, high wear resistance and impact resistance.
Disadvantages: Higher unit prices, longer lead time.
  
Application
Copper wire, aluminum wire, gold wire, titanium alloy wire, etc. that require wire surface shaved.
