PCD (Poly Crystalline Diamond) is, next to a solid diamond, the hardest material known to man. As the market demand increases,For high precision shaft products,Materials such as hard alloy, alloy steel, wear-resisting cast iron, ceramics, etc.The machining process must use a center.

We supply machine centre points equipped with PCD sintered in five veins into a tungsten carbide carrier. Benefits:

* Ultra-High Wear Resistance And Service Life Of 80-180 Times That Of Hard Alloy Center.

* Good  Thermal Conductivity, Reduce The Friction Heat Generated In The Work  And Avoid The Central Hole Of The Workpiece Being Burned And Deformed,  Causing Changes In The Central Position And Affecting The Machining  Accuracy.

* The  Friction Coefficient Is Much Lower Which Cangreatly Reduce The Friction  Resistance, And The Vibration Of Workpiece, To Improve The Processing  Accuracy.

* Polycrystalline  Diamond Under 650° Showed Good Chemical Inertness, Resistant To Strong  Acid,Alkali,Suitablefor All Kinds Of Operating Mode Under The Condition  Of Work.
