What Is TheCVD Diamond

Cvd Synthetic Diamond Is An Acronym For Chemical Vapor Deposition Diamond, Pure Diamond Polycrystalline Structure ,No Cutting Surface,No Metal Binder.

The CVD Diamond Types Include

( MORE SUPERHARD Company Offers A Full Range Of Cvd Diamond Grinding, Cutting, Dressing, Coating ,Thermal And Wear-Part Applications,Etc )

1.CVD Diamond Cutting Tool Blanks. The CVD Diamond Tool Is Made With Cvd Diamond Blanks Without Any Binder, Sharing The Same Surface Smooth Finish As The Natural Single Crystal Diamond. The Working Life Of Cvd Diamond Cutting Tools Are 100 Times Higher Than That Of Hard Alloy.

Applications: Non Ferrous Materials,Ceramics,Abrasive Composites,High Silicon-Content Aluminum Alloy,Graphite And Other Difficult Machining Materials.

2.Cvd Diamond Dressing Tool Blank.Cvd Diamond Dressing Blanks Produced By The High Quality Semitransparent Polycrystalline Diamond, With No Binder Phase,Have Excellent Thermal Stability And High Thermal Conductivity.

Applications:Cvd Diamond Blanks Are Suitable For All Dresser Types, Such As Single Point Dresser,Multi-Point Dresser, Blade, Rotary Dresser, , Polishing Tool, Diamond Dressing Roller And Jewelry Processing Tool, Etc

The Product Grade Include,Standard Grade And High Quality Grade
