Tool Parameter Analysis
Shapes of Flank
The conical flank structure is weak but moresharp.After grinding, the R value will decrease.
Rake Angle
The larger of the positive rake Angle, the sharper the cutting edge. Meanwhile, the strength of the cutting edge is reduced and fragile. And it is easy to wear and crumble.With the increase of the negative rake angle and the cutting force is increase. It is suitable for cutting high strength materials.
The cylindrical flank structure has greater vibration resistance and rigidity. After grinding,the R angle remains basically unchanged.
Relief Angle
The larger of the relief angle, the weaker of the cutting edge.The small relief angles tools are suitable for high strength materials.The large relief angel tools are suitable for soft and low strength materials.
Tool contour Precision
The Sharpness of Cutting Edge
The surface roughness of diamond tool can be less than Ra0.01μm. There is no defects
of cutting edge under the 3000 times microscope. And the friction coefficient is very
small, which can make surface meet the requirements of the super mirror nanometer level.

Waviness Detection
Cutting tool contour precision check ratio:20000x:
We offer the precision of outline and edge radius detection report for each single diamond tool. Because it is non-contact measurement, it will not cause the damage of cutting edge. Test contents include the radius value of the waviness, the angle etc.
